How this service works
MCP discovery audit 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 report containing: the observation (what was found at the target), the threshold being evaluated against, a pass/fail verdict, the exact evidence source URL, any limitations of the passive check, and a mode-specific recommended action. No login, payload injection, or active testing is performed.
Example use cases
Pre-launch agent readiness check
“Before we go live, can you audit https://myproduct.io for MCP discovery compliance and tell me the verdict, what evidence you found, and any limitations I should know about?”
Comparing two sites for MCP signals
“I want to compare MCP discoverability between https://siteA.com and https://siteB.com — can you audit siteA as the target and siteB as the comparison URL and show me how they differ?”
Ongoing monitoring against baseline
“We ran an MCP audit on https://app.company.com last week — here's the baseline result. Can you re-audit it now and tell me if anything has changed in its MCP discovery signals?”
Technical details
Endpoint
POSThttps://agentreadiness.halowerk.com/v1/mcp-discovery-audit?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a passive, evidence-backed verdict on whether a specific public URL or domain exposes MCP discovery signals correctly. It is purpose-built for MCP protocol compliance specifically, unlike generic crawler audits or robots.txt checks on the same platform. Prefer it over sibling endpoints when your concern is specifically MCP discoverability rather than llms.txt availability, generic crawler access, or article entity extraction.
Side effects
- Target URL is unreachable or returns non-200 status — audit cannot retrieve public evidence
- Malformed or overly short target URL rejected at input validation
- Target site blocks crawlers, preventing evidence retrieval — returned as a limitation
- Baseline object schema mismatch causes comparison to fail
- Rate limiting or payment failure on the x402 payment layer prevents call completion
