Anlyon alternative

2 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 2Claude Code: ask
  • calculate_takeoffCalculate an auditable material takeoff from explicit geometry or a supported SmartScale/ProtoGen measurement payload.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
    Calculate an auditable material takeoff from explicit geometry or a supported SmartScale/ProtoGen measurement payload. Returns net, explicit waste-adjusted, and conservative purchase quantities. This is a planning estimate, not a guaranteed material order or professional certification.
  • verify_resultRecompute a takeoff audit hash, notary payload, pack currency, and QT9 unit-resolved conservation.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
    Recompute a takeoff audit hash, notary payload, pack currency, and QT9 unit-resolved conservation. Pass the prior result object as JSON.
Only reads 5Show 5 read-only tools
  • describe_agentReturn fleet-standard capabilities, version, pack digest, disclaimer, composition role, and pricing.No findings

    Why it is in this group

    • The name "describe_agent" says "describe": a word for reading.
    Description, as the server wrote it
    Return fleet-standard capabilities, version, pack digest, disclaimer, composition role, and pricing.
  • get_assemblyReturn one assembly's formula, required dimensions, material factors, purchase increment, sources, and material-pack lineage.No findings

    Why it is in this group

    • The name "get_assembly" says "get": a word for reading.
    Description, as the server wrote it
    Return one assembly's formula, required dimensions, material factors, purchase increment, sources, and material-pack lineage.
  • get_material_packReturn the bundled factors, densities, coverages, waste defaults, purchase increments, unit conversions, sources, and raw-pack SHA.No findings

    Why it is in this group

    • The name "get_material_pack" says "get": a word for reading.
    Description, as the server wrote it
    Return the bundled factors, densities, coverages, waste defaults, purchase increments, unit conversions, sources, and raw-pack SHA.
  • list_assembliesList supported assemblies, required dimensions, formulas, waste defaults, and the current material-pack digest.No findings

    Why it is in this group

    • The name "list_assemblies" says "list": a word for reading.
    Description, as the server wrote it
    List supported assemblies, required dimensions, formulas, waste defaults, and the current material-pack digest.
  • list_material_packList the bundled material pack version, digest, coverage, shapes, rebar sizes, roof pitches, and explicit unsupported policy.No findings

    Why it is in this group

    • The name "list_material_pack" says "list": a word for reading.
    Description, as the server wrote it
    List the bundled material pack version, digest, coverage, shapes, rebar sizes, roof pitches, and explicit unsupported policy.

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 untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://mcp.viridisconservation.com/quantity-takeoff/mcp: tools/list returned 7 tools to an anonymous client, including calculate_takeoff (write), verify_result (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.

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 quantity-takeoff. Review it before you use it.

Pin

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

Pin in CI

Fail a build when the tools you reviewed are not the tools the server serves today.
