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://mcp-security.agentdiet.dev/v1/x402-verifier)
Output
Returns a structured compliance report covering JSON-RPC response validity, measured latency against SLA thresholds, OpenAPI schema presence and correctness, and HTTP 402 x402 payment header fields — indicating which checks passed, failed, or were not applicable for the audited URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I go live, can you run a full compliance audit on my MCP server at https://staging.myagent.io/mcp — I want to know if the JSON-RPC responses, OpenAPI schema, and HTTP 402 headers all look correct.”
Third-party A2A agent SLA verification
“I'm about to integrate a third-party agent at https://partner-agent.acmecorp.com/a2a into my pipeline — can you audit it for JSON-RPC compliance and latency SLA so I know it'll hold up in production?”
x402 payment header validation on agent marketplace listing
“I've listed my service on an x402 marketplace and I need to confirm it's serving the right HTTP 402 settlement headers — can you verify the endpoint at https://api.myservice.dev/v1/agent is x402 v2 compliant?”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/x402-verifier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-enabled API endpoint correctly implements one or more of: JSON-RPC protocol, latency SLA thresholds, OpenAPI schema, or HTTP 402 x402 payment settlement headers. It is particularly valuable for pre-deployment checks, third-party agent integration due diligence, and marketplace listing compliance. Prefer it over generic HTTP probing tools when the target is specifically an agent or MCP endpoint with payment or protocol compliance requirements.
Side effects
- Target URL is unreachable or returns a connection timeout — audit returns network error
- Target URL does not implement JSON-RPC — compliance check fails with protocol mismatch
- Missing or malformed x402 headers — HTTP 402 check fails with header validation error
- URL parameter is missing or empty — request rejected with validation error
- Target service returns unexpected HTTP status codes — partial audit results returned
