Command+K (com.commandplusk/command-k@1.1.0) Command+K v1.1.0, an in-product AI assistant server, was published to the official MCP registry on 2026-09-12 and is distributed as a hosted remote over streamable-http, according to the mcpindex index. The index's semantic screen of the server's tool description returned a PARTIAL status with an advisory posture and no manipulation pattern found, while the deterministic conformance probe has not yet been run. The listing is filed under Memory & RAG, and mcpindex notes the registry listing changed after the screen ran, so the assessed description is no longer the one published. ← Index /leaderboard Command+K Set up and run an in-product AI assistant: widgets, knowledge, MCP connections, usage. The current version, v1.1.0, was published to the official MCP registry on 2026-09-12. It is distributed as a hosted remote over streamable-http, filed under Memory & RAG by this index. Removals and unreachable sources are measured across every server this index tracks, contract drift across the servers that answer in consecutive snapshots; the index's current counts /stats put this record in context. Using Command+K in Claude, Cursor, Gemini CLI, Cline, or Zed? MCP tool contracts can change remotely with no version bump. The mcpindex gate pins each contract and HOLDs the call when it drifts-before your agent acts. Zero credentials. This is not the package install for this server itself use Install this server for that . Rewrites your MCP host config so each server launches behind the gate.
