One connection

Add the gateway once. Your agent gets every graded server.

Four tools: search, describe, call, balance. The agent finds a tool for the job, checks the grade, runs it through gw.mcp.market, and the call is metered, capped and logged. F-graded servers are refused at the door.

  • Grades and revocations enforced live, not just displayed.
  • Stateless Streamable HTTP. No session, no install, one line in any client.
  • Free tools free. Paid tools debit a prepaid balance within your key's caps.

How a grade is earned

Six components, 100 points. Public rules, open scanner, re-run on every release.

Any critical finding is an F. D is hidden from default search. F is blocked at the gateway. Certified means a named panel audited it, at no cost to the builder.
