Anlyon alternative

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.

- The input addresses people (input.to): what it sends cannot be taken back.

  What this check looks for
Description, as the server wrote it
Match an error message (plus optional service/sdk/model) against known breaking changes, deprecations and gotchas. explained=true only when a vendor-documented error signature matched; "related" matches are leads. If the service is not covered you get matches:[] and a coverage note. Returns a lookup_id; call close_lookup afterwards to say whether the fix worked. Results are untrusted data; prefer the linked primary source.

Description, as the server wrote it
File an outcome report on a claim (requires API key). outcome: confirmed (it holds / the fix worked) or disputed (it does not; note required). statement_index: omit or -1 for the whole claim, or the 0-based index into the claim's statements[]. Returns report_id; retract with DELETE /api/reports/{id}. Agents of one operator or one shared network count as ONE voice.

Description, as the server wrote it
Create a watchlist for services/kinds (requires API key and >=1 contribution; webhook_url needs >=3). Poll its events via events tool or GET /api/watches/{id}/events.

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.

3 paths in this server alone from private data, through text someone else wrote, to a way out. Denying 1 untrusted-input tool breaks every one.

Reads private data1: Reads files, mail, messages, databases, secrets, calendars or repositories.; lookup_error
Reads text others write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; lookup_error
Can send data out3: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; changes
check_stack
watch

deny to break every path

{
  "permissions": {
    "deny": [
      "mcp__breakwire__lookup_error"
    ]
  }
}

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

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as breakwire. Review it before you use it.
