-Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports. Native deferred tool loading for Anthropic and OpenAI APIs reduces token overhead and improves tool selection accuracy when MCP servers expose many tools; local models (vLLM, llama.cpp) get a transparent client-side BM25 fallback.

+Turnstone gives LLMs tools — shell, files, search, web, planning — and orchestrates multi-turn conversations where the model investigates, acts, and reports. It runs as:
 
 - **Interactive sessions** — terminal CLI or browser UI with parallel workstreams
 - **Queue-driven agents** — trigger workstreams via message queue, stream progress, approve or auto-approve tool use
 - **Multi-node clusters** — generic work load-balances across nodes, directed work routes to a specific server
-- **Cluster dashboard** — real-time view of all nodes and workstreams, workstream creation with node targeting, reverse proxy for server UIs (only the console port needs network access)
-- **Governance & compliance** — role-based access control, tool policies, usage tracking, and append-only audit logs
+- **Cluster dashboard** — real-time view of all nodes and workstreams, reverse proxy for server UIs
+- **Intent validation** — an LLM judge evaluates every tool call before approval, presenting risk assessments and evidence-based recommendations so users can make informed decisions instead of blindly approving raw tool calls
+- **Governance & compliance** — RBAC, tool policies, prompt templates, workstream templates, usage tracking, and append-only audit logs
 - **Cluster simulator** — test the stack at scale (up to 1000 nodes) without an LLM backend
 
+Works with any OpenAI-compatible API (vLLM, llama.cpp, NVIDIA NIM) or Anthropic's native Messages API. Supports [MCP](https://modelcontextprotocol.io/) for external tool servers with native deferred tool loading on Anthropic and OpenAI APIs (BM25 fallback for local models).

+### Intent Validation (LLM Judge)
+
+Every tool call that requires human approval is evaluated by an intent validation judge that provides a structured risk assessment alongside the approval prompt — so instead of "approve this bash command?", users see a verdict with risk level, confidence, recommendation, and reasoning.
+
+The system uses a two-tier evaluation pipeline:
+
+1. **Heuristic tier** (instant, free) — 23 pattern-based rules classify tool calls by severity. Catches destructive commands (`rm -rf /`, `DROP TABLE`), privilege escalation (`sudo`), credential access, and more. Results appear immediately.
+2. **LLM judge tier** (async) — A full LLM evaluation runs in the background with access to `read_file` and `list_directory` for evidence gathering. The judge can inspect files that a write would overwrite, check directory contents before a delete, and cite specific evidence in its reasoning. Results update the UI progressively when ready.
+
+The judge defaults to the same model as the session (self-consistency) but can be configured to use a separate model — useful when running a small local model for tasks but wanting a commercial model for safety evaluation.
+
+```toml
+[judge]
+enabled = true           # on by default
+model = ""               # empty = same as session model
+provider = ""            # empty = same as session provider
+timeout = 60.0           # generous for local models
+```
+
+Verdicts are persisted for audit and exposed via Prometheus metrics (`turnstone_judge_verdicts_total`, `turnstone_judge_llm_latency_seconds`). See [docs/judge.md](docs/judge.md) for the full guide.

+max tokens, auto-approve policy, token budget, and agent max turns. Templates
+are snapshot-applied once at creation — not a live binding. The
+`workstream_templates` table (migration 011) supports auto-versioning, and
+workstreams record which template and version spawned them. Token budget
+enforcement tracks consumption in `session.send()` with 80% warning and
+100% approval gate via the `__budget_override__` synthetic tool name.
+
+The console admin panel adds 6 governance tabs (Roles, Policies, Templates,
+WS Templates, Usage, Audit) for a total of 11 tabs, all permission-gated.
+Both Python and TypeScript SDKs expose governance methods on the console
+client.

+## Intent Validation
+
+> See also: [Intent Validation guide](judge.md) | [Judge Architecture diagram](diagrams/png/22-judge-architecture.png)
+
+Intent validation provides advisory risk assessments for tool calls that
+require human approval. The system runs a two-tier evaluation pipeline
+implemented in `turnstone/core/judge.py`:
+
+1. **Heuristic tier** (synchronous, sub-millisecond) -- A priority-ordered
+   rule table using fnmatch tool patterns and regex argument patterns. Four
+   severity levels: critical (deny), high (review), medium (review), low
+   (approve). First match wins. The heuristic verdict is attached to the
+   `approve_request` SSE event immediately.
+
+2. **LLM judge tier** (asynchronous, daemon thread) -- A multi-turn evaluation
+   where the judge LLM receives conversation context and tool call details,
+   optionally uses `read_file`/`list_directory` to gather evidence (with
+   security-hardened path blocking), and produces a structured JSON verdict.
+   If the LLM verdict has higher confidence than the heuristic, it replaces
+   it via an `intent_verdict` SSE event.
+
+The judge is session-scoped (`IntentJudge`), lazy-initialized on first
+approval, and configured via the `[judge]` config section or `--judge` CLI
+flags. By default it uses self-consistency (same model), but supports
+cross-model and cross-provider configurations. Sub-agents (plan, task)
+are exempt. All verdicts are persisted to the `intent_verdicts` table
+(migration 012) with the user's final decision, enabling future calibration.
+The console exposes `GET /v1/api/admin/verdicts` for audit queries
+(requires `admin.judge` permission).

 - **Priority**: Higher priority evaluated first, first match wins
 - **Enforcement**: `evaluate_tool_policies_batch()` called in `WebUI.approve_tools()`
   before the `auto_approve` check
+- **MCP granular policies**: MCP resources and prompts are evaluated using their
+  `approval_label` for fine-grained control:
+  - Resource reads: `mcp_resource__{uri}` (e.g., `mcp_resource__file:///docs/*` to allow,
+    `mcp_resource__*` to deny all)
+  - Prompt invocations: `mcp__{server}__{prompt}` (e.g., `mcp__trusted__*` to allow,
+    `mcp__*` to require approval for all)
+  - Built-in tools continue to use `func_name` for backward compatibility
 
 ### Prompt Templates
 
-Reusable system message templates with variable substitution:
+Admin-curated system message templates injected at workstream startup:
 
-- **Variables**: `{{variable_name}}` placeholders in content
-- **Categories**: general, engineering, support, custom
-- **Default flag**: `is_default=true` templates intended for new workstreams
-- **Storage**: `prompt_templates` table with JSON `variables` array
+- **Runtime behavior**: Templates are loaded once at session creation and injected
+  into the system message *before* user `instructions`. Templates set the baseline;
+  instructions customize per-workstream behavior.
+- **Default templates**: All `is_default=true` templates auto-apply to new
+  workstreams, concatenated in alphabetical order by name. Use name prefixes
+  (e.g. `01-safety`, `02-style`) to control ordering.
+- **Explicit selection**: `--template <name>` CLI flag, `template` field on
+  `POST /v1/api/workstreams/new`, console creation modal dropdown, scheduled task
+  config, and channel adapter config. An explicit template *replaces* defaults.
+- **Variables**: Three built-in placeholders resolved at load time:
+  `{{model}}` (active model name), `{{ws_id}}` (workstream ID),
+  `{{node_id}}` (server node ID). Unrecognized placeholders are kept as-is.
+- **Runtime switching**: `/template <name>` to switch, `/template clear` to revert
+  to defaults, `/template` to show current. Persisted across resume.
+- **Categories**: general, engineering, support, custom, mcp
+- **Content limit**: 32 KB per template (enforced on create/update)
+- **Storage**: `prompt_templates` table with JSON `variables` array. Migration 010
+  adds `template` column to `scheduled_tasks`.
+- **MCP sync**: MCP server prompts auto-sync into prompt_templates with
+  `origin="mcp"`, `mcp_server` set, and `readonly=True`. Manual templates take
+  precedence on name collision. MCP-synced content updates reset `is_default` to
+  prevent compromised servers from injecting defaults. Admin UI shows origin badge
+  and disables edit/delete for MCP-sourced templates.
+
+### Workstream Templates
+
+Workstream templates are behavioral profiles applied at workstream creation — the next level beyond prompt templates. While prompt templates inject system message text, workstream templates define the complete workstream configuration.
+
+**What they define:**
+- System prompt (inline text OR reference to a prompt template by name)
+- Model override (empty = server default)
+- Temperature, reasoning effort, max tokens, agent max turns
+- Auto-approve policy (blanket and/or per-tool list)
+- Token budget (0 = unlimited; warns at 80%, requires approval at 100%)
+- Completion notification config (stored for v2 dispatch)
+
+**Storage:** `workstream_templates` table (migration 011) with auto-versioning. Edits snapshot the pre-update state into `workstream_template_versions`. Workstreams record which template and version spawned them via `ws_template_id` + `ws_template_version` columns.
+
+**Applied once at creation:** Template settings are snapshot-applied to the workstream's config. Not a live binding — template updates don't affect running workstreams.
+
+**Prompt template drift detection:** When a workstream template references a prompt template, a SHA-256 hash of the prompt content is stored at ws_template create/update time. At workstream creation, the server compares the stored hash against current content and logs a warning on mismatch.
+
+**Admin API:** 7 endpoints under `/v1/api/admin/ws-templates` (list, create, get, update, delete, version history) plus a read-only summary at `/v1/api/ws-templates`. Permission: `admin.ws_templates`.
+
+**Console UI:** "WS Templates" tab (11th admin tab) with CRUD table, create/edit modals (name, description, system prompt source toggle, model, auto-approve, per-tool auto-approve, temperature, reasoning effort, max tokens, agent max turns, token budget, enabled), and version history modal. "Profile" dropdown on workstream creation modal. "WS Template" dropdown on scheduler create/edit modals.
+
+**Token budget enforcement:** Tracked in `session.send()`. At 80% consumption, emits an info message. At 100%, the next turn requires explicit approval via the `__budget_override__` synthetic tool name (reuses existing approval UI — inline in browser, Discord buttons, bridge auto-approve). The synthetic name can be targeted by tool policies (e.g. `__budget_override__` → `allow` for admins).
+
+**SDK:** Python (`list_ws_templates`, `create_ws_template`, `get_ws_template`, `update_ws_template`, `delete_ws_template`, `list_ws_template_versions`) and TypeScript (`listWsTemplates`, `createWsTemplate`, etc.) on both sync and async console clients. `ws_template` parameter on `create_workstream()` for both server and console SDKs.

+# Intent Validation (Judge)
+
+> See also: [Judge Architecture diagram](diagrams/png/22-judge-architecture.png)
+
+Intent validation provides advisory risk assessments for tool calls that require
+human approval. An LLM judge evaluates each tool call and presents a structured
+verdict alongside the approval prompt, helping users make informed decisions.
+
+## Overview
+
+When a tool call requires approval, the intent validation system runs a two-tier
+evaluation:
+
+1. **Heuristic tier** (instant) -- Pattern-based risk classification using a
+   rule table. Zero cost, sub-millisecond latency.
+2. **LLM judge tier** (async) -- Semantic evaluation using an LLM with
+   read-only tool access. Runs on a daemon thread and delivers its verdict
+   progressively.
+
+The verdict is purely advisory -- the user always makes the final decision.
+
+The heuristic verdict is attached to the `approve_request` SSE event immediately.
+The LLM verdict arrives later via an `intent_verdict` SSE event, allowing the
+UI to show a spinner that resolves into a richer assessment. Both verdicts are
+persisted to the `intent_verdicts` table for audit and future calibration.
+
+---
+
+## Configuration
+
+### config.toml
+
+```toml
+[judge]
+enabled = true
+model = ""                    # empty = same as session model
+provider = ""                 # empty = same as session provider
+base_url = ""
+api_key = ""
+confidence_threshold = 0.7   # reserved for v2 smart approvals (not used in v1)
+max_context_ratio = 0.5       # max % of judge context window for history
+timeout = 60.0                # seconds (generous for local models)
+read_only_tools = true        # judge can use read_file/list_directory
+```
+
+All fields are optional. The judge is enabled by default; use `enabled = false`
+(or `--no-judge` on the command line) to disable it.
+
+### CLI flags
+
+```
+--judge / --no-judge           Enable/disable (default: enabled)
+--judge-model MODEL            Model for judge
+--judge-provider PROVIDER      Provider for judge
+--judge-timeout SECONDS        LLM judge timeout (default: 60)
+--judge-confidence FLOAT       Confidence threshold (default: 0.7)
+```
+
+CLI flags override `config.toml` values.
+
+---
+
+## Judge Model Selection
+
+- **Default (self-consistency)**: When `model` is empty, the session model
+  evaluates its own tool calls. Research shows self-consistency achieves
+  comparable accuracy to multi-agent debate at a fraction of the cost.
+- **Cross-model**: Use a different model for the judge (e.g. local model for
+  the session, commercial model for the judge). Set `model` and `provider`
+  in the `[judge]` config section, or use `--judge-model` / `--judge-provider`
+  CLI flags.
+- **Cross-provider**: When both `model` and `provider` are set, the judge
+  creates its own LLM client. You can optionally specify `base_url` and
+  `api_key` for non-default endpoints.
+
+---
+
+## Heuristic Rules
+
+The heuristic tier scans a priority-ordered rule table (critical first, low
+last) and returns the first matching rule. Each rule has:
+
+- **Tool pattern**: fnmatch glob matched against `func_name` and `approval_label`
+- **Argument patterns**: Regex patterns matched against the tool's primary
+  argument text (command string for bash, path for file tools, JSON for others)
+- **Risk level, confidence, and recommendation**: Pre-assigned per rule
+
+### Rule tiers
+
+| Tier     | Confidence | Recommendation | Examples |
+|----------|-----------|----------------|----------|
+| Critical | 0.90      | deny           | `rm -rf /`, `mkfs`, `dd if=`, pipe-to-shell, chmod 777 on root, write/edit to `/etc/`, `.ssh/` |
+| High     | 0.80      | review         | `sudo`, `kill -9`, destructive git (`reset --hard`, `push --force`, `clean -f`), DROP TABLE, write/edit secrets (`.env`, `.pem`, `.key`), HTTP mutations, `ssh`/`scp` |
+| Medium   | 0.70      | review         | Package installs (`pip`, `npm`, `apt`, `brew`, `cargo`), `write_file` (default), MCP tool calls, Docker operations |
+| Low      | 0.85      | approve        | `read_file`, `list_directory`, `search`, `recall`, `man`, `use_prompt`, read-only bash commands (`ls`, `cat`, `head`, `grep`, `find`, etc.) |
+
+When no rule matches, the heuristic returns a default verdict: medium risk,
+0.50 confidence, "review" recommendation.
+
+The bash "read-only" rule handles simple pipelines and command chains by
+splitting on `|`, `&&`, `||`, and `;`, then checking each segment individually.
+
+---
+
+## LLM Judge
+
+The LLM judge runs on a daemon thread and performs a multi-turn evaluation:
+
+1. **Context preparation**: Recent conversation history is FIFO-truncated to
+   fit within `max_context_ratio` of the judge's context window. The tool call
+   details (name, approval label, full arguments) are appended as a user message.
+2. **Multi-turn loop** (up to 5 turns): The judge can use `read_file` and
+   `list_directory` to gather evidence before rendering its verdict. Each tool
+   result is appended to the conversation and the judge is called again. On
+   the final turn, tools are stripped and a forcing message instructs the
+   judge to render its verdict immediately.
+3. **Verdict parsing**: The judge's final text response is parsed as JSON using
+   a four-stage strategy: direct parse, markdown code block extraction,
+   brace-counting, and regex field extraction as a last resort.
+4. **Arbitration**: If the LLM verdict has higher confidence than the heuristic,
+   it replaces the heuristic via the `intent_verdict` SSE event.
+
+### Read-only tools
+
+When `read_only_tools` is enabled (default), the judge can use two tools:
+
+- **`read_file`**: Read file contents (capped at 32 KB)
+- **`list_directory`**: List directory entries (capped at 200 entries)
+
+Security hardening blocks access to sensitive paths:
+
+| Category | Blocked patterns |
+|----------|-----------------|
+| System directories | `/etc/`, `/root/`, `/proc/`, `/sys/`, `/dev/` |
+| Credential directories | `.ssh`, `.gnupg`, `.aws`, `.config` |
+| Key files | `*.pem`, `*.key`, `*.p12`, `*.pfx` |
+
+### Timeout
+
+The `timeout` setting (default 60 seconds) is a total budget across all judge
+turns. Time is decremented after each LLM call. If the budget expires mid-turn,
+the judge attempts to parse whatever partial response is available.
+
+---
+
+## Verdict Structure
+
+Each verdict (heuristic or LLM) is an `IntentVerdict` with these fields:
+
+| Field            | Type       | Description |

+
+## Session Integration
+
+The judge is lazy-initialized on first use. When `ChatSession` prepares tool
+calls for approval, it calls `_evaluate_intent()` which:
+
+1. Instantiates `IntentJudge` if not already created
+2. Extracts `func_name`, `func_args`, and `approval_label` from each pending item
+3. Calls `judge.evaluate()` which returns heuristic verdicts immediately
+4. Attaches each heuristic verdict to its item as `_heuristic_verdict`
+5. The daemon thread runs the LLM judge and delivers results via `ui.on_intent_verdict()`
+
+Sub-agents (plan agent, task agent) are exempt from intent validation -- they
+always get full tool visibility without judge evaluation.
+
+---
+
+## Storage and Audit
+
+All verdicts are persisted to the `intent_verdicts` table (migration 012):
+
+- Heuristic verdicts are stored when the `approve_request` event is emitted
+- LLM verdicts are stored when the `intent_verdict` event is delivered
+- The `user_decision` column is updated when the user approves or denies
+
+The console admin panel exposes verdict history via:
+
+```
+GET /v1/api/admin/verdicts?ws_id=&since=&until=&risk_level=&limit=100&offset=0
+```
+
+This endpoint requires the `admin.judge` permission.
+
+---
+
+## SSE Events
+
+### `approve_request` (extended)
+
+When the judge is active, `approve_request` items include a `verdict` field
+with the heuristic verdict, and the event includes a `judge_pending` flag
+indicating that an LLM verdict is in flight:
+
+```json
+{
+  "type": "approve_request",
+  "judge_pending": true,
+  "items": [
+    {
+      "call_id": "call_abc123",
+      "header": "bash: npm install express",
+      "preview": "",

+        "func_name": "bash",
+        "intent_summary": "Package installation: npm install express",
+        "risk_level": "medium",
+        "confidence": 0.70,
+        "recommendation": "review",
+        "reasoning": "Command installs a software package which may modify the environment.",
+        "evidence": ["Matched rule: package-install"],
+        "tier": "heuristic",
+        "judge_model": "",
+        "latency_ms": 0
+      }
+    }
+  ]
+}
+```
+
+### `intent_verdict`
+
+Delivered asynchronously when the LLM judge completes. The UI replaces the
+heuristic verdict badge with the LLM verdict:
+
+```json
+{
+  "type": "intent_verdict",
+  "verdict_id": "f7e8d9c0b1a2",
+  "call_id": "call_abc123",
+  "func_name": "bash",
+  "intent_summary": "Install Express.js web framework via npm",
+  "risk_level": "medium",
+  "confidence": 0.85,
+  "recommendation": "review",
+  "reasoning": "The command installs express from npm. This is a well-known package but will modify node_modules and package.json.",
+  "evidence": ["Checked package.json — express is not currently a dependency"],
+  "tier": "llm",
+  "judge_model": "gpt-5",
+  "latency_ms": 2340
+}
+```
+
+---
+
+## v2 Calibration Path
+
+Run v1 with all tools requiring manual approval to build a local verdict
+dataset. The `intent_verdicts` table accumulates `(tool_call, verdict,
+user_decision)` triples over time. In v2, calibration tooling will analyze
+this dataset to:
+
+- Identify tools that are always approved (candidates for auto-approve policies)
+- Detect false positives in heuristic rules
+- Measure LLM judge accuracy against human decisions
+- Recommend policy changes to reduce approval fatigue
+
+This data-driven approach means v1 is both useful on its own and a foundation
+for automated policy tuning.

+
+## MCP Resources
+
+MCP servers can expose **resources** -- named data items (files, database rows,
+API responses) addressable by URI. turnstone discovers resources at startup and
+makes them available to the model via the `read_resource` built-in tool.
+
+### Discovery
+
+During the MCP `initialize` handshake, `MCPClientManager` checks each server's
+capabilities for the `resources` capability. For servers that declare it:
+
+1. `list_resources` fetches static resources (fixed URIs).
+2. `list_resource_templates` fetches URI templates (parameterized patterns like
+   `db://tables/{table}/rows/{id}`).
+
+Both are stored as `{uri, name, description, mimeType, server}` dicts and
+merged into a unified catalog.
+
+### Resource catalog in system message
+
+The first 50 resources are injected into the system message as an XML-delimited
+block so the model knows what URIs are available:
+
+```xml
+<mcp-resources>
+  file:///project/README.md  Project readme
+  db://users/schema  User table schema
+</mcp-resources>
+Use read_resource(uri='...') to access the resources listed above.
+```
+
+### read_resource tool
+
+| Parameter | Type   | Required | Description |
+|-----------|--------|----------|-------------|
+| `uri`     | string | yes      | The resource URI to read. |
+
+- **What it does**: Reads the resource from its MCP server via `MCPClientManager.read_resource_sync()`. Returns text content for text resources or base64-encoded data for binary resources. Output is truncated by the standard tool output limiter.
+- **Auto-approve**: No -- requires user confirmation (reads external data).
+- **Agent availability**: `agent` and `task_agent`.
+
+### Capability guards
+
+The `read_resource` tool schema is always loaded (it is a built-in JSON schema),
+but resource discovery only runs for servers that declare the `resources`
+capability. Servers without the capability contribute zero resources to the
+catalog.
+
+### Refresh
+
+Resource lists stay current through the same three-tier mechanism as tool lists:
+
+1. **Push** -- Servers declaring `resources.listChanged: true` send
+   `notifications/resources/list_changed`, triggering an immediate refresh.
+2. **Periodic** -- Servers without push are polled on the configured refresh
+   interval (default 4 hours, same timer as tools).
+3. **Manual** -- `/mcp refresh` re-fetches resources alongside tools.
+
+---
+
+## MCP Prompts
+
+MCP servers can also expose **prompts** -- reusable message templates with
+optional arguments. turnstone discovers prompts at startup for servers that
+declare the `prompts` capability.
+
+### Discovery
+
+Prompt discovery mirrors resource discovery: `list_prompts` is called during
+the `initialize` handshake. Each prompt is stored with its prefixed name
+(`mcp__{server}__{prompt}`), description, and argument schema.
+
+### use_prompt tool
+
+| Parameter   | Type   | Required | Description |
+|-------------|--------|----------|-------------|
+| `name`      | string | yes      | The prompt name (e.g. `mcp__server__prompt_name`). |
+| `arguments` | object | no       | Key-value argument pairs for the prompt. Values must be strings. |
+
+- **What it does**: Invokes an MCP prompt template by name via `MCPClientManager.get_prompt_sync()`, expanding it into messages. Returns the expanded prompt content formatted as `[role]: content` blocks joined with blank lines. The prompt catalog is listed in the system message so the model knows which prompts are available. Output is truncated by the standard tool output limiter.
+- **Auto-approve**: No -- requires user confirmation (invokes external prompt servers).
+- **Agent availability**: `agent` and `task_agent`.
+
+### Invocation
+
+`MCPClientManager.get_prompt_sync()` calls the server's `get_prompt` method
+with the provided arguments and returns the expanded messages. The `use_prompt`
+built-in tool exposes this to the model as a function call.
+
+### Governance Sync
+
+Discovered MCP prompts are automatically synced into the `prompt_templates`
+governance table as first-class governed templates:
+
+- **Origin tracking**: MCP-sourced templates have `origin="mcp"` and
+  `mcp_server` set to the server name. Manual templates have
+  `origin="manual"`.
+- **Read-only**: MCP-sourced templates are `readonly=True`. The admin API
+  returns 403 on update/delete attempts. The admin UI disables edit/delete
+  buttons and shows an origin badge.
+- **Precedence**: If a manual template and MCP prompt share the same name,
+  the manual template wins and the MCP prompt is skipped (with a log
+  warning).
+- **Lifecycle**: Templates are created on connect, updated on prompt list
+  refresh, and removed when the MCP server no longer exposes the prompt.
+  The sync runs automatically on connect, on `PromptListChangedNotification`,
+  and on manual `/mcp refresh`.
+- **Schema**: Migration 009 adds `origin`, `mcp_server`, and `readonly`
+  columns to the `prompt_templates` table.
+
+The `use_prompt` tool allows the model to invoke any discovered MCP prompt at
+runtime. A catalog of up to 30 prompts is injected into the system message
+inside `<mcp-prompts>` XML tags so the model can discover available prompts.
+
+---
+
+## MCP UI Visibility
+
+MCP server, resource, and prompt counts are surfaced across the UI:
+
+- **Server `/health` endpoint**: Returns `mcp.servers`, `mcp.resources`,
+  `mcp.prompts` when MCP is configured
+- **Server UI**: Magenta status badge in the header showing server count,
+  with resource/prompt counts in tooltip
+- **Console cluster status bar**: MCP metrics (servers/resources/prompts)
+  with magenta LED dot indicator, shown after a divider from workstream
+  metrics
+- **Console node detail**: Per-node MCP summary showing server, resource,
+  and prompt counts
+- **Console collector**: Aggregates MCP counts across all nodes in the
+  cluster overview
+
+MCP indicators use the `--magenta` design token for consistent theming
+across light and dark modes.

 Architecture: the MCP SDK is fully async, but turnstone's ChatSession is
 synchronous.  We bridge the two by running a dedicated asyncio event loop
 in a daemon thread.  ``call_tool_sync`` dispatches coroutines onto that loop
 via ``asyncio.run_coroutine_threadsafe``.

+Refresh: three mechanisms keep tool/resource/prompt lists up-to-date:
+  1. Push notifications — servers declaring ``listChanged`` on the
+     respective capability trigger immediate refresh.
   2. Periodic timer — servers *without* push support are polled on a
      staggered interval (configurable, default 4 h, seeded at launch).
   3. Manual — ``/mcp refresh [server]`` triggers ``refresh_sync()``.
