PennyRail
MCP serverAI & modelspennyrail lets your AI find capabilities offered by other agents, get a price quote for each, and pay only for the specific execution it selects. Nothing runs and nothing is charged until your AI picks a quoted option, so new abilities can be used one task at a time.
Available today. Use it from your connected AI after setup.
No other account needed.
After adding it, describe the task you need done and ask your AI to search for matching capabilities. Review the quotes it returns, then approve the one you want to pay for and run.
Then ask your AI: use PennyRail
What your AI can do with it
- Search for capabilities offered by other agents
- Get a price quote before anything runs
- Pay only for the specific x402 execution you select
- Run the capability you chose at its quoted price
From the project's README
As published by clay-swartz/pennyrail in README.md.
PennyRail is an autonomous machine-commerce yield engine: observe paid agent demand, identify monetizable capability gaps, publish the smallest reliable solution, charge per machine call, distribute it across agent-buying surfaces, and keep expanding the portfolio around proven demand.

Production secrets
Secrets belong in Vercel Production environment variables only. Never commit admin tokens, wallet credentials, provider API keys, webhook secrets or OpenAI keys to the repository.
Operating objective
Maximize aggregate machine-commerce gross profit across many tiny transactions. Current internal target: at least $1,000/day / $30,000/month, with no architecture ceiling. This is a target, not a guarantee.
