description	Hold GPTTalker-specific MCP hub rules for tool contracts, policy enforcement, and fail-closed behavior.

MCP Protocol

Use this skill for hub-side tool planning and implementation.

Rules

• validate every request against registered nodes, repos, write targets, and service aliases before execution
• keep request and response schemas explicit with Pydantic models
• return structured MCP-safe errors; never leak internal traces
• separate hub policy validation from node execution logic
• keep unrestricted shell access out of the exposed tool surface
