  Matched text
  description: "...match. Returns a 90 day listing-control credential; identical retries recover that grant...."
  What this check looks for
Description, as the server wrote it
Confirm a one-hour domain challenge with the same private requester key. Exact HTTPS origin and path must match. Returns a 90 day listing-control credential; identical retries recover that grant. A new proof revokes prior credentials. Confirmation does not approve branding or change grades. Never signs payments.

  inputSchema.properties.origin.description: "Public HTTP(S) origin only; no credentials, path, query or fragment. Use paths for..."
  What this check looks for
Description, as the server wrote it
Start or recover an asynchronous x402 conformance scan. For new origin-only calls, this MCP tool defaults to quote_mode fast and returns an unsigned 402 quote without starting a scan. Capability-only recovery requires the original input or proof; use get_scan_status for capability polling. Resend the same arguments with payment_signature only after independent payment authorization. Supplying idempotency_key without quote_mode retains compute-first admission. Save the job/capability and poll. Never signs payments.

Use X-Mekler-Listing-Control and the expected revision to hide a listing, suppress branding or revoke access. Domain proof is rechecked after seven days; failed, stale, revoked or expired credentials deny control. Concurrent writes return 409.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; get_service
scan_origin
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

14 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
