# PlanMcp

MCP server that exposes plan-specific tools for writing, editing, and submitting implementation plans for user approval/feedback. Agents refer to plans by `planName`; the server maps that name to `<planName>-plan.md` inside the configured plans directory.

By default, built-in Aether wiring stores plans at `${WORKSPACE}/docs/aether/plans`. Standalone `plan-mcp` defaults to `docs/aether/plans` relative to the server process cwd. Configure another directory with `--plans-dir`.

Alternatively, the server can hand submitted plans off to an arbitrary external CLI. Any trailing positional tokens in the `mcp.json` `args` array are treated as the submit command; the resolved absolute plan path is appended as its final argument, and stdout is forwarded verbatim to the agent as `feedback`.

```json
{
  "servers": {
    "plan": {
      "type": "in-memory",
      "args": ["--plans-dir", "docs/plans", "contextbridge", "plan", "--project", "foo"]
    }
  }
}
```

With the above config, calling `submit_plan` with `planName=docs-site-refresh` invokes:

```
contextbridge plan --project foo <absolute-path-to>/docs/plans/docs-site-refresh-plan.md
```

A non-zero exit code surfaces as a tool error; an exit code of `0` returns `{ "approved": false, "feedback": "<stdout>" }` regardless of stdout content — the agent reads the feedback and decides how to proceed.
