Title: ToolPin as reference for MCP server pinning + drift protection?

Body:

Hi maintainers,

The official MCP servers repo itself uses .mcp.json.

ToolPin is a lightweight open-source tool that adds:

• Committed mcp-lock.json with artifact + tool surface hashing (including input schemas)
• toolpin ci + GitHub Action drift gate
• Vendor-neutral spec

Would you be open to a demonstration PR adding a lockfile + ToolPin workflow as a canonical example for the ecosystem?

Completely opt-in. I can do the work in a fork first.
