Sourcebook

Sourcebook is an MCP server that provides live codebase intelligence for AI agents and assistants. It enables agents to query real-time structural and semantic information about a repository, including test file completeness, import graphs, co-change analysis, and codebase conventions. Through both rules-based and AI-powered analysis, Sourcebook ensures changes are contextually complete and flags files that are likely to require edits, improving the reliability and depth of agent-driven code modifications. It integrates with tools and assistants like Claude, Cursor, Windsurf, and other MCP-compatible clients, making it valuable for teams building or deploying AI code assistants.
