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)
Output
Returns a structured compliance report covering: JSON-RPC spec adherence, measured latency against SLA thresholds, OpenAPI schema presence and validity, and HTTP 402/x402 settlement header correctness — giving a pass/fail breakdown per protocol dimension for the audited URL.
Example use cases
Pre-launch MCP server compliance check
“Before I publish my MCP server, can you run a full compliance audit on https://mcp.myservice.dev/v1 and tell me if it passes JSON-RPC, OpenAPI schema, and latency SLA checks?”
Verifying a third-party x402 payment endpoint
“I'm about to integrate this monetized agent API at https://partner-agent.io/v2 — can you audit it to confirm its HTTP 402 settlement headers are correct and it meets x402 v2 spec?”
Diagnosing a failing agent-to-agent endpoint
“My A2A service at https://agents.myplatform.com/rpc keeps getting rejected by downstream agents — can you audit it to find out if it's a JSON-RPC issue, a latency problem, or something wrong with the protocol headers?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-monetized API meets protocol-level requirements before integration or production deployment. It is the right choice when you need a multi-dimensional compliance check covering JSON-RPC, OpenAPI, latency SLA, and HTTP 402 headers in a single call, rather than testing each dimension manually. Prefer it over generic HTTP testing tools when the target is specifically an AI agent or MCP endpoint using modern agentic protocols.
Side effects
- Target URL is unreachable or returns a network error — audit fails with connectivity error
- Target URL does not expose any recognized protocol surface (not JSON-RPC, MCP, or x402) — report reflects no compliance signals
- Latency of the target service causes audit timeout — SLA result marked as failed
- Malformed or missing URL parameter — returns validation error
- Target endpoint blocks external probes or requires authentication — partial or empty audit results
