What Claudex does
According to its repository: “Persistent memory and full-text search over Claude Code conversation history indexed into SQLite, with session summaries and a web UI for exploration.”
An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Claudex is listed under Memory and knowledge, a category of 250 servers in the directory, where it ranks #73 by stars.
Topics declared by the repository: claude-ai, claude-code, conversation-viewer, fastify, react, sqlite.
Installing and connecting Claudex
Distribution modes declared in the official MCP registry:
- npm package (Node.js, usually started with
npx)
Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: TypeScript. Listed systems: macOS, Windows, Linux.
Security: what to check
An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.
None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Claudex. That does not replace reading the code.
Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.
Project activity and maintenance
Created on October 3, 2025, the kunwar-shah/claudex repository has 97 stars and 11 forks, with 0 open issues. It has more stars than 66% of the servers in the directory. Last change 4 months ago. Version published in the registry: 1.3.4 (May 3, 2026).
Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
