## Description

This MCP server provides AI assistants with intelligent search capabilities across Claude Code conversation history, built by the Claude Code Community using TypeScript with an intelligent indexing system that prioritizes recent activity and content richness for fast retrieval. The implementation offers seven specialized tools including conversation search with AI-enhanced query expansion, file context discovery, similar query matching, error solution patterns, tool usage analysis, and session management, all backed by a robust parser that extracts file references, tool usage patterns, and error contexts from JSONL conversation logs stored in ~/.claude/projects. Built with performance optimizations including circuit breakers, memory limits, and caching mechanisms, it serves developers needing to leverage their coding conversation history for debugging and learning, teams wanting to discover patterns in their AI-assisted development workflows, and users seeking to quickly find relevant past solutions and context from their Claude Code sessions.
