How this service works
MCP discovery decision fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.
Output
Returns a structured assessment including: the observed evidence from the target URL, the threshold criteria applied, a pass/fail/unknown verdict, the exact evidence source URL, any limitations of the passive inspection, and a recommended mode-specific action the caller should take next.
Example use cases
Pre-integration MCP readiness check
“Before we integrate with this vendor, can you check if https://platform.acme.com supports MCP discovery and tell me if the evidence is solid enough to proceed?”
Monitoring a partner API for MCP support
“I want to know if our partner at https://api.partner.io has added MCP discovery yet — can you fetch the current public evidence and give me a verdict?”
Comparing MCP discovery between two URLs
“Can you evaluate https://v2.myservice.com for MCP discovery and compare it against https://v1.myservice.com to see if the new version improved agent readiness?”
Technical details
Endpoint
POSThttps://agentreadiness.halowerk.com/v1/mcp-discovery-decision?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a passive, non-intrusive check of whether a specific public URL or domain advertises MCP discovery capabilities. Prefer it over generic HTTP probing when you want a structured verdict with evidence sourcing, thresholds, and recommended actions rather than a raw HTTP response. Ideal for pre-integration checks, partner audits, and automated agent-readiness pipelines where no login or payload injection is acceptable.
Side effects
- Target URL is unreachable or returns non-2xx status, resulting in no evidence and an inconclusive verdict
- Domain normalization fails for malformed input URLs
- Target blocks crawler user agents, causing evidence gaps and a limited verdict
- MCP discovery endpoint exists but is behind authentication, which passive inspection cannot evaluate
- Rate limiting or timeouts on the target produce incomplete evidence
