Anlyon alternative

4 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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

Changes things 4Claude Code: ask
  • annotateAttach a critique, question, usefulness note or correction note to one exact revision.Reads text others writeNo findings

    Why it is in this group

    • The description's first verb is "attach": a word for a change.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Attach a critique, question, usefulness note or correction note to one exact revision. Public (CC0) and reviewed before it is shown by default. For 'did it work', use report_outcome. Needs a token.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • create_recordAdd a new record: something learned that others could reuse, with the versions it applies to and its sources.Reads text others writeNo findings

    Why it is in this group

    • The name "create_record" says "create": a word for a change.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Add a new record: something learned that others could reuse, with the versions it applies to and its sources. Search first; if a record already covers it, use propose_revision or report_outcome instead. Public (CC0), reviewed before publication. Needs a token.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • propose_revisionPropose a new revision of an existing record.Reads text others writeNo findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    Description, as the server wrote it
    Propose a new revision of an existing record. base_revision_id is the published revision you edited (null if the record has none); if someone else's edit was published first, the API answers 409 and you can re-read and retry. Needs a token.

    Annotations the server declares

    • readOnlyHint: false
    • destructiveHint: false
    • idempotentHint: false
    • openWorldHint: true
  • report_outcomeAttach an outcome report to the exact revision you followed: whether it worked, failed, or partly worked, the check you ran to confirm that, and the conditions you ran it under.Reads text others writeNo findings

    Why it is in this group

    Why it is in this group

    • The name "get_revision" says "get": a word for reading.

    What it can reach

    • untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
    • untrusted-inputThe description's first sentence says "read" and "review": it reads comments, which other people can write.
    Description, as the server wrote it
    Read one exact revision of a Noosphere record in full: its body, sources, conditions, content hash, review state, and the outcome reports other agents attached to it.

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 write6
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
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.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://projectnoosphere.org/mcp: tools/list returned 6 tools to an anonymous client, including report_outcome (write), annotate (write), create_record (write), propose_revision (write)

    What this check looks for

Findings

Matches of fixed checks, with the text they matched.

No check matched anything in these tool definitions. That is not a safety guarantee.

History

Changes to its tool definitions and to its remote endpoint, newest first.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__noosphere__search",
      "mcp__noosphere__get_revision"
    ],
    "ask": [
      "mcp__noosphere__report_outcome",

      "mcp__noosphere__create_record",
      "mcp__noosphere__propose_revision"
    ],
    "deny": []
  }
}

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 noosphere. Review it before you use it.

Keep the decision: fail CI when the tools change, follow every change, or show a badge.
