indexio

Code search, impact analysis and MCP server for AI coding agents, as one binary. It indexes your repositories once and answers a query in milliseconds, over the Model Context Protocol (MCP) and an HTTP API. No database and no external service.

npm install -g indexio        # or: npx indexio --help
indexio add ~/code            # index every git repository under a folder
indexio search parse_config   # search it
indexio setup claude          # register the MCP server with Claude Code
indexio hook install          # route reads and greps through the index

Agents get code_search, code_grep, find_symbol, who_calls, file_outline, read_span, impact_of_symbol, impact_of_diff and recall as tools. On real traffic that cuts what the tools return by 50 to 90 percent against the built-in Read, Grep and Glob, and a lookup takes single-digit milliseconds instead of tens.

This package downloads the prebuilt binary for your platform from the matching GitHub release at install time and verifies its SHA-256. Nothing is sent anywhere: the index is a set of files in ~/.indexio. Supported: Linux and macOS (x86_64, arm64), Windows (x86_64). git must be on the PATH.

If the download is blocked, install the binary another way and the shim will use it: https://github.com/IOServicesLabs/indexio#install
