- loads enabled bundle-MCP servers for the current workspace and merges them with any existing backend MCP config/settings shape;
- rewrites the launch config using the backend-owned integration mode from the owning plugin.
Restricted runs such as cron jobs with `toolsAllow` require an exact
backend-owned translation. The bundled `claude-cli` backend disables Claude's
native tools and user, project, and local customizations, including hooks,
plugins, agents, skills, and `CLAUDE.md`. It then exposes every allowed
OpenClaw tool through the grant-scoped MCP server. This keeps filesystem,
process, exec, approval, and sandbox policy inside OpenClaw instead of widening
authority to Claude's native tools or customization processes. The same MCP
list is enforced in Claude's generated config and again by the Gateway on tool
listing and execution. Before minting the grant, core rejects backend
translations that name any MCP permission outside the original allowlist.
Backends without an exact translation still fail closed.
If no MCP servers are enabled, OpenClaw still injects a strict config when a backend opts into bundle MCP, so background runs stay isolated.
Session-scoped bundled MCP runtimes are cached for reuse within a session, then reaped after 10 minutes of idle time. One-shot embedded runs such as auth probes, slug generation, and active-memory recall request cleanup at run end so stdio children and Streamable HTTP/SSE streams do not outlive the run.

- No direct OpenClaw tool calls: OpenClaw does not inject tool calls into the CLI backend protocol. Backends only see gateway tools when they opt into `bundleMcp: true`.
- OpenClaw does not inject tool calls into the CLI backend protocol. Backends only see gateway tools when they opt into `bundleMcp: true`.
- Streaming is backend-specific: some backends stream JSONL, others buffer until exit.
- Structured outputs depend on the CLI's own JSON format.

closed when the backend cannot enforce the restriction. MCP names in this
context are safe to auto-approve only because the host has already limited the

To support OpenClaw runtime caps such as cron `toolsAllow`, also implement
`resolveRuntimeToolAvailability(ctx)`. OpenClaw passes a normalized,
group-expanded allowlist and always disables backend-native tools. Return only
host-isolated MCP names selected from that allowlist. Returning `null` or
`undefined` keeps the generic runner fail-closed. A backend may omit an allowed
tool it cannot represent, but must never add authority absent from the
allowlist. Before minting a grant, the host rejects any returned entry that is
not the exact `mcp__openclaw__<tool>` name for one of the allowed tools.

OpenClaw fails closed if the backend cannot do so.
To accept runtime caps such as cron `toolsAllow`, the backend must also
implement `resolveRuntimeToolAvailability`; OpenClaw disables all native
tools and fails closed if the backend cannot translate or enforce the MCP
cap.
