How this service works
Audits any remote agent or MCP URL for JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 settlement headers. (Live x402 v2, IETF MPP & MCP endpoint at https://preflight.agentdiet.dev/v1/mcp-security-scan)
Output
Returns a structured compliance report including JSON-RPC conformance status, measured latency against SLA thresholds, OpenAPI schema validation results, and presence/correctness of HTTP 402 (x402 v2) settlement headers for the audited endpoint URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I go live, can you run a full compliance audit on https://tools.mycompany.ai/v1/mcp — I want to know if its JSON-RPC responses, latency SLA, and HTTP 402 headers all pass?”
Verify x402 payment header support on agent API
“I'm integrating a third-party agent at https://api.agentservice.io/v1/run — can you check whether it properly supports HTTP 402 x402 v2 settlement headers before I wire up payments?”
Ongoing quality check on a vendor MCP endpoint
“Can you probe https://vendor.example.com/mcp-endpoint and tell me if it's fully A2A and MCP protocol compliant, including its OpenAPI schema and response latency?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/mcp-security-scan?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that a remote A2A agent, MCP server, or x402-enabled service conforms to protocol standards before integrating it into an agent pipeline or paying for its services. It is especially useful for pre-deployment compliance gating, third-party vendor due diligence, or continuous monitoring of agent infrastructure health.
Side effects
- Target URL is unreachable or times out — audit returns connectivity error
- URL does not implement any recognized A2A/MCP/x402 protocol — partial or null compliance results
- Malformed URL input — returns validation error
- Target endpoint blocks external probes — incomplete audit results
- Rate limiting on the audited endpoint — latency SLA may reflect throttling rather than true performance
