ruvnet-brain is an MCP server by stuinfla. RuvNet Brain — a downloadable, source-grounded brain for Claude Code over Reuven Cohen's (rUv's) RuvNet stack: RuVector/RVF, Ruflo, AgentDB, RuLake, SPARC + 21 building blocks. Grounds Claude in real source via one MCP tool (search_ruvnet), so it builds with the stack instead of drifting off it. It has 76 GitHub stars and ranks #422 of 1287 in Memory & Knowledge by stars.

How to install ruvnet-brain

ruvnet-brain is published on npm as ruvnet-brain. These steps assume it runs as a local stdio server, which is the usual setup.

Check the README. Confirm the start command and note any API keys or environment variables it needs (pass them with -e KEY=value or an env block). You need Node.js for npx.

Add it to Claude Code from a terminal:

claude mcp add ruvnet-brain -- npx -y ruvnet-brain

Or add it to Cursor or Claude Desktop in .cursor/mcp.json or claude_desktop_config.json:

{
  "mcpServers": {
    "ruvnet-brain": {
      "command": "npx",
      "args": [
        "-y",
        "ruvnet-brain"
      ]
    }
  }
}

Restart the client and check it. Run claude mcp list, or open the client's MCP settings, and confirm ruvnet-brain and its tools are listed. The install guide covers VS Code and Codex.
