Implementation Reference
- codebrain/server.py:330-343 (handler)The 'codebrain_status' tool handler (registered via @mcp.tool()). Calls list_models() and reports which Ollama models are available locally.
@mcp.tool() async def codebrain_status() -> str: """Report which Ollama models are available locally. Call this to verify the local backend is reachable and discover which models the user has pulled. """ try: models = await list_models() except BackendError as exc: return f"[codebrain error] {exc}" if not models: return "No models installed. Run `ollama pull qwen2.5-coder:14b` to add the default." return "Installed models:\n" + "\n".join(f" - {m}" for m in models) - codebrain/server.py:330-330 (registration)The @mcp.tool() decorator registers 'codebrain_status' as an MCP tool on the FastMCP server instance.
@mcp.tool() - codebrain/backend.py:58-68 (helper)The list_models() helper function that queries Ollama's /api/tags endpoint and returns a list of installed model names.
