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.

  • reorder_print_jobA REORDER ALSO REQUIRES A NEW VISUAL PREVIEW AND BUYER CONFIRMATION.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
    A REORDER ALSO REQUIRES A NEW VISUAL PREVIEW AND BUYER CONFIRMATION. First call preview_print_order with reorder_of and any desired changes, show every image/options/price to the buyer, and obtain confirmation. Then call this with preview_id, preview_version and buyer_confirmed=true, without option overrides. Without a preview this returns a preview only; it never creates an order. In preview_print_order, quantity means complete sets for multi-part reorders; material/color overrides apply to every part. Omit overrides to preserve choices. Prices are recalculated. The previous order's geometry is reused without requesting a new upload. Shipping/contact details are never copied from the previous order; confirm the new address with the buyer. Orders cancelled by HardCopy Labs or still awaiting payment cannot be reordered. Returns a new job ID, total and payment link when payment is required, only after the new preview is confirmed.

    Why it is in this group

    • The name "submit_print_job" says "submit": 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
    Create an order ONLY AFTER preview_print_order, image display and buyer confirmation. First present every preview image (or the viewer fallback), dimensions, material/color, quantity and quote. Obtain explicit buyer confirmation for that preview version. Then send preview_id, preview_version, buyer_confirmed=true, job_name and shipping details ONLY; omit model/options fields. Any relevant change needs a new preview. Legacy model inputs without a preview return a preview and NEVER create an order. Set geometry, material, color, quantities and operator notes in preview_print_order. OpenSCAD is preferred for designs made in conversation; uploaded STL and cached model IDs are also supported there. One preview covers the whole multi-part order. Confirm the shipping address with the buyer. ship_to requires their full name and US address; contact_email is used for updates. This returns a job ID and total, plus a payment link when payment is required. The buyer pays in their own browser.

    Why it is in this group

    • The name "check_job_status" says "status": a word for reading.
    Description, as the server wrote it
    Look up the current status of a print job (submitted, approved, printing, QC, shipped) and its UPS tracking number once shipped. Use when the user asks about an order they placed with HardCopy Labs.

    • idempotentHint: true
    • openWorldHint: false
  • preview_print_orderMANDATORY before creating any order or checkout, including reorders.No findings

    Why it is in this group

    • The name "preview_print_order" says "preview": a word for reading.
    Description, as the server wrote it
    MANDATORY before creating any order or checkout, including reorders. Render exact validated geometry and quote the whole order. Display EVERY returned part image with name, dimensions, material/color, quantity, notes and total to the buyer. The in-chat card shows images where supported; otherwise embed image_url values or give viewer_url and ask the buyer to review there. Never substitute an AI illustration, or describe unshown images as reviewed. Ask for explicit buyer confirmation of this version only after presenting the preview. Changes require a new preview and new confirmation; pass replaces_preview_id to revoke the old preview. Preview failure blocks ordering. After confirmation call submit_print_job (or reorder_print_job) using preview_id, preview_version, buyer_confirmed=true and shipping/contact details; do not resend models or option overrides. Preview generation and viewing never create an order. Separate parts are displayed individually, not as an inferred assembly.

    • idempotentHint: true
    • openWorldHint: false
  • validate_stlCheck whether a 3D model can be printed, before ordering.No findings

    Why it is in this group

    • The name "validate_stl" says "validate": a word for reading.
    Description, as the server wrote it
    Check whether a 3D model can be printed, before ordering. A text validation quote is NOT approval to order. Call preview_print_order next, show its exact model images/options/price to the buyer, then obtain confirmation. Use this when the user has an STL file (base64-encoded) and wants to know if it is printable, or as a pre-check before submit_print_job. Returns printability (watertight/manifold status), dimensions, which printers it fits on, and the total for each material: what submit_print_job will charge for this file, shipping included. If the user is designing an object in this conversation, generate the STL, then call this to confirm it can be manufactured. Pass quantity (default 1) when the user wants several copies, so the totals cover all of them. For multiple parts, pass the WHOLE order in parts with each material/color/quantity. Never add separate quotes: totals already include shipping and handling once. To keep payloads small, validate each STL first and reuse its model_id (24 hours). PLA and PETG are the only materials offered.

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 write2
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.hardcopylabs.com/mcp: tools/list returned 5 tools to an anonymous client, including submit_print_job (write), reorder_print_job (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.

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

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 hardcopy. Review it before you use it.
