Cursor Publishes a Formal Plugin Specification Repo Separate From MCP
cursor/plugins (2,497 stars, 192 forks, 27 open issues, created 2026-01-23, pushed 2026-07-31) holds the Cursor plugin specification and official plugin implementations in TypeScript, appearing in today's trending TypeScript list at +27 stars. Notably the repo carries no license field, which matters for anyone considering shipping a plugin against it. Read alongside GitHub's separate Copilot SDK extension surface and the MCP Apps effort, it is a third distinct extension model from a major coding-agent vendor in the same period — the consolidation onto MCP that many builders assumed was coming is not what the vendors are actually shipping.
