delete_assetSTOP monitoring one of YOUR assets and remove it, by its asset id (from list_my_assets).No findings
Why it is in this group
- The name "delete_asset" says "delete": a word for removing or ending something.
- The description says "irreversible".
- The server marks it destructive (destructiveHint: true).
Description, as the server wrote it
STOP monitoring one of YOUR assets and remove it, by its asset id (from list_my_assets). This is irreversible — its check history goes too. Requires an API key with write scope.

Changes things 9Creates or changes something that can be changed back.Claude Code: ask

acknowledge_alertAcknowledge one of YOUR alerts by its alert id (from list_my_alerts) — marks it as seen/being-handled without resolving it.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
Description, as the server wrote it
Acknowledge one of YOUR alerts by its alert id (from list_my_alerts) — marks it as seen/being-handled without resolving it. Optionally attach a note. Requires an API key with write scope.
Annotations the server declares
- readOnlyHint: false
- destructiveHint: false
- idempotentHint: true
- requiresAuth: true
check_agent_readinessScore how ready a website is for AI agents and answer engines.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Score how ready a website is for AI agents and answer engines. Fetches /llms.txt, /robots.txt, and the homepage and returns a letter grade with per-signal findings. No browser rendering or LLM call — deterministic HTTP/parse.
Annotations the server declares
- readOnlyHint: true
check_broken_linksScan one web page for dead links (4xx/5xx/unreachable) and mixed content (http subresources on an https page).1 finding

  Matched text
  annotations: {"readOnlyHint":true}; The name "check_broken_links" says "link": a word for a change.
  What this check looks for
Description, as the server wrote it
Scan one web page for dead links (4xx/5xx/unreachable) and mixed content (http subresources on an https page). Returns each link with its status. Single-page scan, not a crawl — pass the exact page URL. Rate-limited to a few scans per minute, so batch calls will be throttled.

check_domain_healthCheck the live SSL/TLS certificate (validity + expiry + issuer), DNS records (A/AAAA/MX/NS resolution), and domain-registration (RDAP) expiry of any public hostname.No findings

Description, as the server wrote it
Check the live SSL/TLS certificate (validity + expiry + issuer), DNS records (A/AAAA/MX/NS resolution), and domain-registration (RDAP) expiry of any public hostname. Each leg fails soft and is reported independently.

Description, as the server wrote it
Check whether a domain or IP is listed on the major DNS blocklists (DNSBLs) that mail providers consult before accepting mail — the usual reason legitimate mail silently lands in spam. Returns each zone checked, whether it is listed, and the return code. Deterministic DNS lookups, no LLM.

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Health-check a live MCP (Model Context Protocol) server by URL: performs a real JSON-RPC initialize handshake, then tools/list, and returns whether it is up/degraded/down, its protocol version, server name/version, the callable tool/resource/prompt inventory, transport, and handshake latency. Deterministic — no LLM. Use it to verify your own MCP server is alive and spec-compliant.

10 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.
