No install snippet on purpose. A working MCP config is a command, its arguments and an environment block — the last two are where API keys live, so this catalogue never stores them and cannot publish them. Follow the link above for the authors' own instructions.
Ontario checks whether a paid endpoint is readable, challenge-correct, discoverable, and ready for an agent's task before a wallet signs. It is free to diagnose the buyer path and publish a provider profile for 0.50 USDC, which includes a readiness report, discovery observations, and 30 days of evidence maintenance. The tool supports free, read-only checks such as verifying x402/Bazaar readiness and discovering endpoints with grade=ready without requiring a wallet or payment.
The project provides a free live trust preview that can be used by MCP hosts via the agent_trust_preview function before selecting a paid scan. Ontario offers a paid Agent Trust Scan for 0.01 USDC that submits an agent's card URL or A2A endpoint and returns a structured trust report. Ontario integrates with Coinbase Bazaar and other x402 providers, as the same client SDK works against Ontario, Coinbase Bazaar, or any other x402 provider.
It includes an Agent Payment Firewall that gates autonomous x402 spending based on readiness, price, network, asset, report freshness, and can-pay policy.
