CoverBureau MCP Server
Remote MCP server (JSON-RPC 2.0 over HTTP POST) that reads US ACORD 25 Certificates of Insurance, judges them against caller-supplied requirements and returns Ed25519-signed verdicts. Tools are extract_coi ($0.02/call), validate_coi ($0.075/call) and check_carrier ($0.01/call); no account or API key, unpaid calls return HTTP 402 with an x402 payment challenge settled in USDC on Base mainnet. No OpenAPI, AsyncAPI or GraphQL contract is published; the tool input schemas were captured from the live tools/list response.
