Ontario Protocol MCP server

Ontario Protocol

Find out why an agent cannot discover or call your x402 API, then publish the evidence a buyer needs to evaluate it.

Run the free buyer-discovery audit

Install in your agent

Launch multiple x402 endpoints: validate a public services manifest, select up to ten endpoints, and inspect the 0.50 USDC per-endpoint publication quote. The plan does not authorize payment. Use your existing wallet or MCP client and retain each successful receipt.

Catalog Watch is a free customer-run Python kit for scheduled public-profile observations, before/after webhook alerts, and gated refresh jobs after included maintenance. It is not a hosted subscription and never signs or spends.

For API providers preparing a launch:

npx skills add TheTechDevPro/ontario-protocol --skill ontario-provider-launch

For agent builders checking an endpoint before spending:

npx skills add TheTechDevPro/ontario-protocol --skill ontario-x402-preflight

Or install both from the Ontario x402 Toolkit pack:

npx skills add https://skills.sh/p/1i9kLVcmDbP4Zbhz

The pack is a public, unlisted snapshot of these two skills, published September 6,

1. It is not a leaderboard placement, endorsement, or security certification.

Skills contain inspectable instructions. Installation does not create a wallet, authorize a purchase, or change spending limits.

Connect

The remote uses Streamable HTTP. No Ontario API key is required for free tools. For clients using mcpServers, including Claude Code's .mcp.json:

{
  "mcpServers": {
    "ontario-protocol": {
      "type": "http",
      "url": "https://ontarioprotocol.com/mcp"
    }
  }
}

For VS Code, see examples/vscode-mcp.json. The official Registry record and Smithery listing point to the same remote. A connected MCP host still needs a compatible local x402 wallet and explicit spend policy to use paid tools.

Try a useful task

Check whether my public x402 API appears in Bazaar for "return a sourced

company filing". Report observable blockers. Do not spend or publish anything.

Or call the free HTTP diagnostic directly:

curl --fail-with-body --silent --show-error \
  https://ontarioprotocol.com/api/tools/coinbase-bazaar-readiness \
  -H 'Content-Type: application/json' \
  -d '{"target_url":"https://example.com/api/paid","buyer_query":"return a sourced company filing"}'

Replace the example URL with your own public API. The result separates indexing preflight from sampled buyer-query retrieval, with evidence and timestamps. It does not initiate a settlement or submit your service to another registry.
