What it does

Code Index MCP provides a high-performance indexing and search layer for local code repositories. By leveraging Zoekt's trigram-based indexing, it allows AI assistants to perform complex substring and regex searches across large codebases with minimal latency, far surpassing standard grep-based approaches.

Tools

index_directory: Indexes a local source code directory for fast searching.
search_code: Executes complex searches across indexed directories using Zoekt syntax (regex, file filters, etc.).
list_indexes: Lists all currently indexed directories and their storage locations.
delete_index: Removes the index for a specific directory to free space or refresh data.
index_info: Retrieves metadata and configuration details about the indexing process.
