Anlyon alternative

3 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.

calculate_etsy_paybackCalculate profit, break-even sales/months and capacity from explicit user inputs.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
Calculate profit, break-even sales/months and capacity from explicit user inputs. No tax or wage deduction; no predicted sales or prefilled Etsy fees.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
calculate_laser_setupAdd a user-supplied machine quote and explicitly selected accessory costs in one currency.1 finding
Why it is in this group
- The description's first verb is "add": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  What this check looks for
Description, as the server wrote it
Add a user-supplied machine quote and explicitly selected accessory costs in one currency. Include all eight checklist entries; use null for an unknown cost, not an assumed zero.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
calculate_maker_priceCalculate a starting selling price from explicit per-item costs, machine/hands-on minutes, hourly costs, user-supplied fees and a profit buffer.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
Calculate a starting selling price from explicit per-item costs, machine/hands-on minutes, hourly costs, user-supplied fees and a profit buffer. No fee lookup or currency conversion.
Annotations the server declares
- readOnlyHint: true

compare_machinesCompare two to four known machine IDs using dated specifications, setup requirements, strengths, limitations and sources.No findings
Why it is in this group
- The name "compare_machines" says "compare": a word for reading.
Description, as the server wrote it
Compare two to four known machine IDs using dated specifications, setup requirements, strengths, limitations and sources. No overall score or invented compatibility.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
find_laser_materialReturn the existing cautious source-level laser/material/task guidance and sources.No findings
Why it is in this group
- The name "find_laser_material" says "find": a word for reading.
Description, as the server wrote it
Return the existing cautious source-level laser/material/task guidance and sources. Unknown material means stop. This is not certification of safety or exact machine compatibility.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
find_machinesFilter researched machines by process, material/use, reference budget, buying-link market and workshop requirements.No findings
Why it is in this group
- The name "find_machines" says "find": a word for reading.
Description, as the server wrote it
Filter researched machines by process, material/use, reference budget, buying-link market and workshop requirements. Unknown requirements do not satisfy explicit filters. Market links do not imply stock.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_buying_optionsRead existing retailer links for one machine and an explicitly chosen buyer country.No findings
Why it is in this group
- The name "get_buying_options" says "get": a word for reading.
Description, as the server wrote it
Read existing retailer links for one machine and an explicitly chosen buyer country. Includes affiliate disclosures and dated observations; never purchases or confirms live stock.
Annotations the server declares

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.

Findings

Matches of fixed checks, with the text they matched.

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 maker-machines-atlas. Review it before you use it.

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.
