Direzione di ricerca

Start by locating the buyer skill's x402 MCP transport and its existing tests or examples. Then check how it handles tools/list, an unpaid tools/call, payment metadata, a paid retry, and the settlement response against the public HumanMirror endpoint. Done means a documented optional workflow exercises that sequence; the issue does not name repository files or tests.

Descrizione

The buyer skill now supports the x402 MCP transport, but I could not find a public mainnet conformance fixture in this repo that exercises the full MCP flow end-to-end against an independent seller.

Would it be useful to add one documented external fixture for:

  1. tools/list discovery
  2. unpaid tools/call → PaymentRequired in structuredContent
  3. payment in _meta["x402/payment"]
  4. paid retry
  5. settlement in _meta["x402/payment-response"]

HumanMirror can serve as that fixture without requiring an account or API key.

Public MCP server:
POST https://humanmirror.fr/api/x402/mcp/

Two paid tools:

  • humanmirror_machine_resolve — 0.001 USDC on Base
  • humanmirror_safe_preflight — 0.010 USDC on Base

The MCP-originated PaymentRequired now uses the x402 MCP resource identity form:
mcp://tool/

and includes Bazaar MCP discovery metadata (type=mcp, toolName, inputSchema, example, streamable-http).

Canonical discovery:
https://humanmirror.fr/.well-known/x402
https://humanmirror.fr/kit.json

Independent public evidence already exists that HumanMirror is x402-compliant and listed in CDP Bazaar:
https://forgemesh.io/partners/humanmirror

I am not proposing a special-case integration or any change to MetaMask payment policy. The useful outcome would be a small optional example/conformance workflow that lets contributors test the MetaMask buyer against a live third-party seller.

If you prefer a different public seller for the fixture, the same test shape would still be valuable; I can help adapt the HumanMirror side if your MCP buyer exposes a stricter requirement than the current x402 v2 spec.
