Jarvis MCP server

jarvis

Your coding agent should not spend its context window on grep.

When your agent asks "where is AuthService used?", grep returns comments, markdown, test fixtures, and similarly named symbols in one noisy pile. The agent burns context re-reading files to filter signal from noise — and still misses call sites.

jarvis precomputes a local code-intelligence layer so your agent calls findReferences for exact occurrences, goToDefinition for the defining range, callHierarchy for call paths, and searchCode for precise lexical search — ten MCP tools for Claude Code, Cursor, or any MCP client. Your code and indexes never leave your machine.

Quick start

1. Install the standalone binary:

brew install jarvis-intelligence/jarvis/jarvis

Linux users need Homebrew/Linuxbrew installed first. The formula supports macOS arm64/x8664 and Linux arm64/x8664, installs both jarvis and jarvis-server, and embeds Python 3.12, dashboard assets, tree-sitter libraries, watch, scip, zoekt-git-index, and zoekt-webserver. Homebrew supplies universal-ctags. No Python, uv, pip, or PyPI installation is required.

Upgrade with brew upgrade jarvis; recover a damaged installation with brew reinstall jarvis.

2. Index a repo (slug defaults to the directory name):

jarvis index /path/to/your/repo

3. Register the MCP server:

claude mcp add jarvis --scope user -- jarvis-server

Ask your agent "find all references to AuthService" — it calls findReferences instead of grepping.

Other MCP clients (Cursor, Claude Desktop, any stdio client)

{
  "mcpServers": {
    "jarvis": {
      "command": "jarvis-server"
    }
  }
}

If your client can't find jarvis-server on PATH (GUI apps often don't inherit your shell's), use the absolute path from which jarvis-server.

Claude Code plugin (registers MCP + ships agent skills)

Install the Homebrew binary first. The plugin adds jarvis skills and can register the already-installed jarvis-server.

/plugin marketplace add jarvis-intelligence/jarvis-index
/plugin install jarvis@jarvis

Optional language indexers

The standalone package includes the SCIP converter and both Zoekt binaries. The Homebrew formula does not install setup.sh; from a jarvis source checkout, install the optional per-language indexer for your repo:
