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/mpp-verifier)
Output
Returns a structured compliance report covering JSON-RPC protocol adherence, measured latency vs. SLA thresholds, OpenAPI schema validity findings, and the status of HTTP 402 / x402 settlement headers for the audited endpoint URL.
Example use cases
Pre-deployment MCP server validation
“Before I add this MCP server at https://tools.mycompany.ai/v1/mcp to our agent swarm, can you audit it for JSON-RPC compliance, latency SLA, and HTTP 402 settlement headers so I know it's ready?”
Third-party A2A agent vetting
“I'm about to integrate a vendor's A2A agent at https://partner.example.com/agent — can you run a protocol compliance check on it to see if it passes JSON-RPC and OpenAPI schema validation?”
x402 payment endpoint preflight check
“Can you audit https://api.myservice.dev/v1/pay to confirm that the HTTP 402 x402 payment headers are set up correctly and the endpoint is SLA-compliant before we go live?”
Technical details
Endpoint
GEThttps://preflight.agentdiet.dev/v1/mpp-verifier?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a structured, multi-dimensional compliance check specifically covering JSON-RPC correctness, latency SLA, OpenAPI schema, and HTTP 402 payment headers on an A2A, MCP, or x402 service — particularly during pre-deployment validation, third-party agent vetting, or ongoing protocol conformance monitoring. Prefer this over generic uptime monitors or ping tools when protocol-level compliance details matter.
Side effects
- Target URL is unreachable or times out — audit fails with a connectivity error
- URL points to a non-agent or non-MCP service — compliance checks return not-applicable or fail
- Malformed or missing URL parameter — returns 400 bad request
- Target service blocks external probes — partial or empty audit results
- x402 headers absent on a non-payment endpoint — 402 check returns not-configured
