Usage

First Time Setup

When you first use the MCP, you need to index your existing conversations:

Use the tool: index_conversations

This will scan your ~/.claude/projects directory and index all conversations.

Searching Your History

Search for specific errors, code patterns, or topics:

Use the tool: search_history with query: "CORS error"
Use the tool: search_history with query: "database connection"
Use the tool: search_history with query: "TypeError"

Getting Full Conversation Details

After searching, you can get the full conversation:

Use the tool: get_conversation with conversationId: "abc123"

Listing All Projects

See all your indexed projects:

Use the tool: list_projects

How It Works

The MCP:

1. Reads your Claude Code conversation history from ~/.claude/projects
2. Indexes conversations in a local SQLite database
3. Provides full-text search capabilities
4. Returns relevant snippets and full conversation details

Data Storage

• Database location: ~/.claude-code-mcp/history.db
• No data is sent to external services
• Your conversation history stays local

Roadmap (v2)

• [ ] Semantic search using embeddings
• [ ] Auto-indexing with file watcher
• [ ] Conversation summarization with GPT-4
• [ ] Export/import functionality
• [ ] Search filters (date, project, success/failure)
