onyx-paid-mcp — build a paid MCP server in 5 lines

USDC settlement on Base. No Stripe, no API keys, no signup flow. Charge AI agents per call directly through the protocol they already speak.

from onyx_paid_mcp import App

app = App(
    name="hello-paid-mcp",
    receive_address="0xYourBaseWallet",
    network="base",   # or "base-sepolia" for free testnet
)

@app.tool(
    name="echo",
    price_usdc="0.001",
    description="Returns whatever you send.",
    input_schema={"type": "object", "properties": {"text": {"type": "string"}}, "required": ["text"]},
)
def echo(text: str) -> dict:
    return {"echoed": text}

if __name__ == "__main__":
    app.serve(port=8080)

That's it. pip install onyx-paid-mcp, point at any wallet address, decorate any function. You now have:

Streamable HTTP MCP at /mcp/ — installable in Claude Desktop, Cursor, Cline, mcp-use
REST endpoint at /v1/<tool> — for non-MCP agents
HTTP 402 gate that charges your wallet per call in USDC
Bazaar-discoverable manifest at /.well-known/x402.json — Coinbase auto-indexes
Free introspection at /, /manifest, /health

Why

Every MCP today is free-as-in-unmetered. That breaks at scale for any tool with real per-call expense (OCR, scraping infra, LLM passes, anything backed by a physical resource). onyx-paid-mcp lets you charge directly through the agent's wallet — the same way a paywall works in a browser, except the wallet signs an EIP-3009 USDC authorization instead of pulling out a credit card.

Install

pip install onyx-paid-mcp

Generate a Base wallet (gen_wallet.py in this repo, or any EVM wallet generator), set it as ONYX_RECEIVE, run your tool. Agents pay you in USDC the second they call.

Reference implementation

onyx-actions — the live server using this framework. Paid tools across Base on-chain primitives, captcha OCR, URL text extraction, DNS, WHOIS, email validation, IP geo, FX, browser automation, and a workflow chainer. All shipped as one-file modules in tools_pkg/.

How agents call you

Try it against the live reference server with one command — no install:

curl -X POST https://onyx-actions.onrender.com/v1/onyx_solana_jupiter_quote \
  -H "content-type: application/json" \
  -d '{"input_mint":"So11111111111111111111111111111111111111112","output_mint":"EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v","amount":"1000000000"}' -i
