indexio MCP server

indexio

indexio is a code search engine for AI coding agents. It indexes all the repositories of an organization one time. It answers a query in milliseconds. It gives the index to agents as a tool through the Model Context Protocol (MCP) and through an HTTP API.

indexio is one binary, written in Rust. It does not need a database or an external service. The index is a set of files in one data directory. You can copy that directory to another machine.

Let your agent install it

Paste the block below to Claude Code, Cursor, Codex or any coding agent that can run shell commands. It installs indexio, indexes your code, registers the MCP server and verifies the result. Replace ~/code with the folder that holds your repositories.

Install indexio (https://github.com/IOServicesLabs/indexio) on this machine and connect it
to me. Do these steps in order and stop at the first failure with the exact error.

1. Install the binary.
   - Linux or macOS:  curl -fsSL https://raw.githubusercontent.com/IOServicesLabs/indexio/main/install.sh | sh
   - Windows (PowerShell):  irm https://raw.githubusercontent.com/IOServicesLabs/indexio/main/install.ps1 | iex
   - If neither works, use `pip install indexio-cli`, `npm install -g indexio`, or `cargo install --git https://github.com/IOServicesLabs/indexio indexio`.
   The binary lands in ~/.local/bin (Linux, macOS) or %LOCALAPPDATA%\Programs\indexio (Windows).
   If `indexio --version` is not found afterwards, add that folder to PATH and open a new shell.
   `git` must be on PATH.

2. Index my code:  indexio add ~/code
   This registers every git repository under the folder at any depth and builds the index.
   Nothing is uploaded; the index lives in ~/.indexio.

3. Register the MCP server with the agent you are.
   - Claude Code:  indexio setup claude --claude-md ~/.claude/CLAUDE.md
     then  indexio hook install
     (the hooks route file reads and greps through the index; 

What the agent gets afterwards: codesearch, codegrep, findsymbol, whocalls, fileoutline, readspan, impactofsymbol, impactofdiff and recall as tools, answered from the index in milliseconds. The tools table describes each one.

Install

Pick one. Each one gives you the indexio command.
