How this service works
WebMCP agent-compatibility check: does a website expose a WebMCP tool surface agents can call? Inventory, schema-hygiene findings and readiness verdict
Output
Returns a structured report containing: the inventory of WebMCP tools exposed by the target website, schema hygiene findings identifying any malformed or non-compliant tool definitions, and an overall agent-readiness verdict indicating whether the site is properly configured for AI agent tool calling.
Example use cases
Vetting a vendor for agent integration
“Before I wire up my AI agent to use Shopify's APIs, can you check if shopify.com has a WebMCP-compatible tool surface and flag any schema hygiene issues I should know about?”
Developer self-audit before launch
“I'm about to launch my SaaS — can you run a WebMCP compatibility check on myapp.io and tell me whether agents can discover and call my tools correctly?”
Competitive agent-readiness benchmarking
“Check openai.com, anthropic.com, and cohere.com for WebMCP tool surfaces — I want to know which ones have a proper agent-callable setup and which ones fail the readiness verdict.”
Technical details
Endpoint
GEThttps://agentx.sale/x402/webmcp-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically verify WebMCP protocol compatibility and tool discoverability for a given domain, rather than general agent-readiness (use the Site Agent-Readiness Verdict Card for broader checks) or x402 payment compliance (use x402 Doctor for that). Best when you want a focused inventory of callable tools plus schema lint findings.
Side effects
- Host not reachable — domain does not resolve or times out
- No WebMCP surface detected — site does not expose any WebMCP endpoint
- Schema parsing error — the site's WebMCP manifest is malformed beyond recovery
- Rate limit or payment failure — x402 payment not processed
- Invalid host parameter — malformed or missing host query parameter
