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://prompt-guard.agentdiet.dev/v1/mpp-verifier)
Output
Returns a structured audit report covering JSON-RPC protocol compliance, measured latency against SLA thresholds, OpenAPI schema validity, and HTTP 402 payment header correctness for the target URL.
Example use cases
Pre-deployment MCP server compliance check
“Before I publish my new MCP server at https://tools.mycompany.com/mcp, can you audit it to make sure it's properly JSON-RPC compliant and has valid OpenAPI schema documentation?”
Verifying x402 payment header setup
“I set up HTTP 402 payment gating on my API at https://api.myservice.dev/v1/data — can you check whether the x402 settlement headers are configured correctly?”
Third-party A2A agent SLA validation
“I'm thinking about integrating an external agent at https://partner-agent.example.com/a2a into my workflow — can you run a full compliance and latency SLA audit on it first?”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/mpp-verifier?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically verify that an A2A agent, MCP server, or x402-gated API meets protocol compliance standards before integration or deployment, especially when you need simultaneous validation of JSON-RPC spec, latency SLA, OpenAPI schema, and HTTP 402 payment headers in a single call.
Side effects
- Target URL is unreachable or times out — audit cannot be completed
- Target service returns unexpected non-standard responses that cannot be parsed for compliance
- Invalid or malformed URL provided as input
- Target service has no HTTP 402 headers, resulting in empty payment compliance section
- Rate limiting or network restrictions prevent the auditor from reaching the target
