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/preflight)
Output
Returns a compliance report object covering JSON-RPC spec adherence, measured latency vs. SLA thresholds, OpenAPI schema validity findings, and HTTP 402 x402 payment settlement header analysis for the submitted endpoint URL
Example use cases
Pre-integration MCP server compliance check
“Before I wire up this new MCP server at https://tools.mycompany.ai/mcp, can you run a full compliance audit on it — JSON-RPC spec, latency SLA, and OpenAPI schema?”
x402 payment header verification
“I built an HTTP 402 endpoint at https://api.mybiz.dev/pay — can you audit it to confirm the x402 v2 settlement headers are properly configured and the payment flow will work?”
A2A agent SLA health check
“My A2A agent at https://agent.myfleet.dev/v1 has been acting weird — can you probe it for protocol compliance issues, check its latency against SLA targets, and tell me what's wrong?”
Technical details
Endpoint
GEThttps://prompt-guard.agentdiet.dev/v1/preflight?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify that a remote A2A agent, MCP server, or x402-enabled API meets protocol and SLA standards before integration — especially when you need simultaneous checks across JSON-RPC compliance, latency, OpenAPI schema, and HTTP 402 payment headers in a single call rather than assembling separate tools
Side effects
- Target URL is unreachable or returns a network error
- Target endpoint does not respond within the audit timeout window
- Malformed or missing URL parameter causes a 400 validation error
- Target returns unexpected content type preventing schema analysis
- x402 headers absent or malformed on the target endpoint
