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/preflight)
Output
Returns a structured compliance report including JSON-RPC spec adherence, measured latency vs SLA thresholds, OpenAPI schema validation results, and HTTP 402 / x402 v2 settlement header presence and correctness for the target URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I add this new MCP server at https://tools.myagent.ai/mcp to my agent fleet, can you audit it for JSON-RPC compliance, latency SLA, and proper HTTP 402 payment headers?”
x402 payment header verification
“I'm building an x402-enabled API at https://api.myservice.dev/v1/execute — can you check whether the HTTP 402 settlement headers are correctly set up according to the x402 v2 spec?”
A2A agent endpoint health audit
“We just deployed an A2A agent endpoint at https://agents.company.com/worker — can you audit it for protocol compliance, OpenAPI schema validity, and latency SLA before we route live traffic to it?”
Technical details
Endpoint
GEThttps://mcp-security.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a specific remote agent, MCP server, or x402-enabled API is correctly implementing JSON-RPC, latency SLAs, OpenAPI schemas, and HTTP 402 payment settlement headers before integrating it into an autonomous agent workflow or swarm. It is specifically designed for A2A/MCP/x402 protocol compliance, not generic HTTP health checks.
Side effects
- Target URL is unreachable or returns a non-2xx/402 status — audit fails with connectivity error
- Malformed or missing URL parameter — returns validation error
- Target service has no OpenAPI schema exposed — schema check returns not-found
- Latency measurement times out if target is slow or unresponsive
- x402 headers absent or malformed — reported as non-compliant rather than erroring
