Persistent memory + FTS5 search MCP server for Claude Code conversation history.
Most knowledge and memory work still happens through a UI a human drives. Claudex MCP server moves it into the conversation instead. Persistent memory + FTS5 search MCP server for Claude Code conversation history.
Claudex is a full-stack web application designed for developers, QA engineers, and researchers who need to inspect, search, and analyze Claude Code conversation histories. Built with React and Fastify, it provides enterprise-grade full-text search using SQLite FTS5, universal template support for all Claude Code versions, and comprehensive analytics dashboards.
The server publishes 5 tools. What each one is for:
Prerequisites — The Prerequisites tool exposed by this serverInstallation — The Installation tool exposed by this serverSearch — The Search tool exposed by this serverExport — The Export tool exposed by this serverHealth — The Health tool exposed by this server~/.claude/projectsThe server ships on npm as @kunwarshah/claudex, 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.
This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Claudex's toolset — Prerequisites, Installation, Search and 2 more — is a fair guide to whether it matches your workflow. It is maintained by kunwar-shah; 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We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
