Block Xcode Index MCP Server
Open-source MCP server from Block (Square) that gives AI agents direct access to Xcode's project index store through Apple's IndexStoreDB. Enables precise code navigation and refactoring operations on iOS and macOS projects with tools for loading project indexes, finding symbol occurrences, retrieving symbol references, and pattern-based symbol searching. Agents can find all call sites of a function and perform exhaustive refactoring across large Swift and Objective-C codebases.
