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/paywall-scanner)
Output
Returns a structured compliance report covering JSON-RPC protocol adherence, measured latency vs SLA thresholds, OpenAPI schema validity, HTTP 402 x402 settlement header correctness, and an overall protocol compliance status for the audited endpoint.
Example use cases
Verify new MCP server before integration
“Before I wire up this MCP server into my agent stack, can you audit https://tools.myservice.com/mcp and tell me if it's properly JSON-RPC compliant and what its latency looks like?”
Check x402 payment header correctness
“I built a paywalled API at https://api.myagent.dev/v1/search and I want to make sure the HTTP 402 x402 headers are set up correctly — can you run a compliance check on it?”
Pre-launch A2A agent endpoint audit
“We're about to go live with our A2A agent at https://agent.company.io/v2/actions — can you do a full compliance audit including OpenAPI schema validity, SLA latency, and JSON-RPC format before we launch?”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/paywall-scanner?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that an A2A agent, MCP tool server, or x402-paywalled API is correctly implementing its protocol stack — particularly JSON-RPC compliance, latency SLAs, OpenAPI schema correctness, and HTTP 402 payment header format. It is especially useful before integrating a third-party agent endpoint into a production system, or when debugging why an x402 payment handshake is failing.
Side effects
- Target URL is unreachable or returns a network error
- Target URL is not an A2A/MCP/x402 endpoint and returns unexpected content type
- URL missing or empty — required parameter not provided
- Target endpoint times out before SLA measurement completes
- Target returns malformed or non-standard HTTP 402 headers that cannot be parsed
