CLI harnesses (claude-cli, gemini-cli) cannot enforce runtime toolsAllow, so
Crestodian previously fell back to the single-turn planner for them. The
openclaw-tools stdio MCP entry can now serve the ring-zero crestodian tool
(OPENCLAW_TOOLS_MCP_TOOLS=crestodian), and Crestodian CLI runs inject it as the
run's exclusive MCP surface: no loopback server, no plugin/user MCP servers,
with the server kept under the "openclaw" name so existing tool pre-approvals
apply. agent-turn routes configured or detected CLI-harness models through
runCliAgent with native session resume across turns, keeps embedded toolsAllow
enforcement for API-key models and the Codex app-server fallback, and still
degrades to the planner when no loop backend works.
The host-verified approval contract survives the process boundary: per-turn
arming and the pending exact-operation hash travel to the stdio server via the
generated MCP config env, and the host mirrors proposal transitions back from
harness tool events (denial registers the hash, mismatch voids it, execution
consumes it) so a generic yes can never authorize a different mutation. The
trust model (the CLI owns its native tools) is documented in
docs/cli/crestodian.md.
