fortytwo-mcp — Claude Code plugin: what it does, how to install
This plugin routes demanding questions from Claude Code to Fortytwo Prime, where independent AI nodes work together on an answer. Use it for architecture reviews or difficult debugging.
/plugin marketplace add anthropics/claude-plugins-community
/plugin install fortytwo-mcp@claude-communityWhat fortytwo-mcp does
fortytwo-mcp connects Claude Code to Fortytwo Prime, a system that combines responses from several independent AI nodes. Once installed, the skill is available automatically, and the agent can use it when it recognizes a relevant task.
Each request is paid through the x402 protocol in USDC on Base or Monad. The first call starts a payment challenge; later calls in the same session are free. Plan for a charge before making that first request.
What it helps with
- review an architecture for weak points
- investigate a concurrency bug
- find a safer fix for a code issue
- get input on a difficult question spanning several fields
Example prompts for the agent
- Ask Fortytwo Prime to review this architecture and find its weak points.
- Ask Prime to investigate this concurrency issue and suggest a safer fix.
- Use Fortytwo Prime to work through this complex question.
