Anlyon alternative

5 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.

Why it is in this group
- The name "create_design" says "create": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  The server marks "create_design" read-only (readOnlyHint: true), and its own name, description or input give the class "write".

Description, as the server wrote it
Compiles a short brief into a complete design with the configurator defaults; the centre given by place or lat and lon is the centre of tile 0. Invalid values fall back to their defaults with a notice naming the brief field. Change the result with edit_design.

  What this check looks for
Description, as the server wrote it
Changes a design and returns the complete changed design, validated against the rules and the limits of anonymous use. changes takes brief fields (an absent field keeps the design: width, rotation, model_width, exaggeration, relief, frame, colors, label, tiles, shape, or place or lat and lon to move the centre of tile 0); patch takes JSON Patch operations for every other field, applied after changes. The service stores no design: send the complete design every time and continue with the returned one.
Annotations the server declares
- title: Edit design
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
edit_tilesAdds a tile at, or removes the tile at, a compass side of a tile and returns the updated design.1 finding

render_designRenders a design as an image, returns its summary, and opens the interactive 3D viewer where the host supports 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.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Renders a design as an image, returns its summary, and opens the interactive 3D viewer where the host supports it. The default overview shows four 3D views from the north, east, south, and west beside the top view with north up and a scale bar, so proportions and relief read from every side; view top or oblique with a direction gives one larger view, resolution high doubles the size. A repeated render of the same design and options is answered from the cache.
Annotations the server declares
- title: Render design
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
share_designStores the design and returns a link, valid for 90 days, that opens exactly this design in the NeuronForm configurator.No findings
Why it is in this group

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 write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; list_templates
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.

Findings

Matches of fixed checks, with the text they matched.

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 neuronform. Review it before you use it.
