Claudex
Search and recall past Claude Code threads with persistent memory and FTS5 full-text search from your current session.
Overview
Claudex is a Build-phase MCP server that adds persistent memory and FTS5 search over Claude Code conversation history for coding agents.
What is this MCP server?
- Persistent memory backed by local Claude Code conversation storage
- FTS5 full-text search across historical agent sessions
- npm stdio package @kunwarshah/claudex v1.3.4
- Optional PROJECT_ROOT env pointing at Claude Code log directory (default ~/.claude/projects)
- GitHub repository kunwar-shah/claudex
- Registry version 1.3.4
- npm package @kunwarshah/claudex

What problem does it solve?
Claude Code solo builders repeat context and lose prior fixes because past sessions are buried in local logs with no agent-visible search.
Who is it for?
Heavy Claude Code users on long-horizon repos who want searchable session memory without a separate notes app.
Skip if: Cursor-only workflows without Claude logs, teams needing cross-user team memory, or builders who want cloud-hosted shared memory.
What do I get? / Deliverables
After stdio setup, your agent can query indexed conversation history and surface relevant prior threads while you code.
- Full-text search hits across stored Claude Code conversations
- Persistent memory surface exposed as MCP tools
- Faster continuity across multi-session solo builds
Recommended MCP Servers
Journey fit
Canonical shelf is Build / agent-tooling because Claudex extends Claude Code itself with durable conversation recall while you ship. Agent-tooling is where IDE-adjacent MCP servers live; Claudex indexes ~/.claude/projects logs for FTS5 search across sessions.
How it compares
Claude Code log search MCP, not a general codebase RAG or Superpowers planning skill.
Common Questions / FAQ
Who is Claudex MCP for?
Solo developers using Claude Code who want MCP tools to search and reuse conversation history from prior agent sessions.
When should I use Claudex MCP?
During Build and Operate iteration when you need to recall earlier agent decisions, debugging notes, or plans stored in Claude Code logs.
How do I add Claudex MCP to my agent?
Install @kunwarshah/claudex, add the stdio server in your MCP config, optionally set PROJECT_ROOT to your log path, then restart Claude Code.
