Search Claude Code conversation history with natural language queries across all projects
Claude MCP server is a locally run integration for AI assistants that speak the Model Context Protocol. Search Claude Code conversation history with natural language queries across all projects.
Find any conversation across all projects: bash "where did we discuss the database issue?" "find that authentication conversation" "docker configuration we talked about yesterday"
The server ships on npm as claude-code-conversation-search-mcp, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Once Claude is connected, these are the calls the assistant has available:
Contributing — 1. Fork the repository 2. Create a feature branch (git checkout -b feature/amazing-feature) 3. Commit your changes (git commit -m 'Add amazingYou will need 2 environment variables: DEBUG, CONVERSATION_DB_PATH. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Claude's toolset — Contributing — is a fair guide to whether it matches your workflow. It is maintained by TonySimonovsky; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
