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://serp-extract.agentdiet.dev/v1/mpp-verifier)
Output
Returns a structured compliance report covering JSON-RPC protocol conformance, latency SLA pass/fail, OpenAPI schema validity, and HTTP 402 / x402 settlement header inspection for the submitted target URL.
Example use cases
Pre-integration MCP server health check
“Before I add this MCP server at https://tools.myagent.dev/mcp to my agent stack, can you audit it for JSON-RPC compliance, latency SLA, and whether its HTTP 402 headers are set up correctly?”
x402 payment header verification
“I deployed a new x402-enabled endpoint at https://api.mybusiness.dev/v1/service — can you check that it's returning the correct HTTP 402 payment settlement headers and that it's IETF MPP compliant?”
Routine SLA audit for agent fleet endpoint
“Run a compliance audit on https://agent.myplatform.io/rpc and report back on its JSON-RPC validity, OpenAPI schema, and whether it's meeting latency SLA benchmarks.”
Technical details
Endpoint
GEThttps://serp-extract.agentdiet.dev/v1/mpp-verifier?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 correctly implements protocol-level standards — including JSON-RPC compliance, latency SLA, OpenAPI schema, and HTTP 402 payment headers — before integrating it into an agent workflow or marketplace listing. Prefer it over generic uptime monitors or HTTP health-check tools when protocol-layer compliance (especially x402/MPP and MCP) is what matters.
Side effects
- Target URL is unreachable or returns a network timeout — audit fails with connectivity error
- Target URL does not expose a valid HTTP endpoint — schema and header checks return empty or error
- Malformed or non-URL input causes validation rejection before request is sent
- Target service blocks automated probes, returning 403 or CAPTCHA — audit results incomplete
- x402 or JSON-RPC headers absent — report reflects non-compliance rather than an error
