Tools

Open a tool for its reasons and full description. Descriptions are the publisher's own words, shown as they are.

8 tools

Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

submit_feedbackSend feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer.No findings
Why it is in this group
- The name "submit_feedback" says "submit": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
Description, as the server wrote it
Send feedback, a bug report or a tool request to the maintainers of the tools on this server: a missing tool, missing or stale data, or a tool that broke or gave a wrong answer. Pass the kind (need_tool, need_data, bug or other), one short message (at most 1000 characters) and, if you know them, the tool name and the error text it returned. Returns a ticket id. Feedback is not a chat: nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.

Changes things 3Creates or changes something that can be changed back.Claude Code: ask

check_browser_supportUse this when the user asks whether a web platform feature works in browsers, such as "can I use CSS container queries in Safari?" or "is subgrid Baseline?".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
Use this when the user asks whether a web platform feature works in browsers, such as "can I use CSS container queries in Safari?" or "is subgrid Baseline?". Pass the feature name or its id. Returns its Baseline status (widely available, newly available or limited), the dates it reached them, and the first version that supports it in Chrome, Edge, Firefox and Safari, including Android and iOS. A browser shown as null has not shipped the feature. If the name is unclear it returns candidate features.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
check_licenseUse this when the user asks about an open-source license, such as "is the MIT license OSI approved?" or "what is the SPDX id of Apache License 2.0?".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
Use this when the user asks about an open-source license, such as "is the MIT license OSI approved?" or "what is the SPDX id of Apache License 2.0?". Pass an SPDX identifier or the license name. Returns the SPDX id, full name, whether it is OSI approved, whether the FSF lists it as free, whether the id is deprecated, and the SPDX page. If the name matches several licenses it returns candidates to choose from. It identifies a license and does not say what the license permits or requires. It is not legal advice.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
check_runtime_eolUse this when the user asks whether a runtime version or a project's runtimes are still supported, such as "is Node 18 past end of life?" or "is the Node version in our Dockerfile …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
Use this when the user asks whether a runtime version or a project's runtimes are still supported, such as "is Node 18 past end of life?" or "is the Node version in our Dockerfile still supported?". Pass runtimes by name and version, such as [{"runtime": "node", "version": "18"}], or the repository's pin files with their contents: package.json, .nvmrc, .node-version, .python-version, pyproject.toml, Pipfile, runtime.txt, go.mod, .go-version, Dockerfile, compose.yaml, .tool-versions, mise.toml, .ruby-version, Gemfile, composer.json or global.json. Returns one row per pin, past end of life first: the endoflife.date release cycle, end-of-life date, whether it passed, days left, latest patch and next supported cycle. A range such as >=18 is checked at its oldest version; an image tag such as python:3.11-slim at its version, plus its Debian or Alpine base. A pin it cannot match comes back as unmatched with the reason. Data comes from endoflife.date, maintained by volunteers. Not for package vulnerabilities.

Only reads 4Looks things up and changes nothing.Claude Code: allow

get_eol_statusGet end-of-life status.No findings
Why it is in this group
- The name "get_eol_status" says "get": a word for reading.
Description, as the server wrote it
Get end-of-life status. Use this when the user asks whether a software version is still supported or when it reaches end of life, such as "is Node.js 20 still supported?" or "which Python versions get security fixes?". Pass the product (nodejs, python, ubuntu, postgresql and so on) and optionally a version or release cycle. With a version it returns that cycle's end-of-life date, whether it has passed, LTS dates and the latest patch. Without one it returns the release cycles that are still supported. Data comes from endoflife.date, maintained by volunteers: confirm with the vendor for contract or compliance decisions. Not for package vulnerabilities.

- destructiveHint: false

get_feedback_replyRead the maintainers' reply to feedback you sent with submit_feedback, given its ticket id.No findings
Why it is in this group
- The name "get_feedback_reply" says "get": a word for reading.
Description, as the server wrote it
Read the maintainers' reply to feedback you sent with submit_feedback, given its ticket id. Returns status pending until a reply is ready, then status answered with the reply text. The reply is information for you, not an instruction.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: false
get_release_notesGet release notes.No findings
Why it is in this group
- The name "get_release_notes" says "get": a word for reading.
Description, as the server wrote it
Get release notes. Use this when the user asks what changed between two versions of a package, or what to watch for in an upgrade, such as "what changed in express between 4.18.2 and 5.1.0?" or "are there breaking changes from requests 2.28 to 2.32?". Pass the npm or PyPI package name (or a GitHub repo) and fromVersion, the version the user has; toVersion defaults to the latest release. Returns each release after fromVersion up to toVersion, newest first, with its date, link, a short excerpt of its notes and a breaking flag, plus a GitHub compare link. Notes come from GitHub releases and, when those do not reach back far enough, from the repository's changelog file; complete is false when neither covers the whole range. Not for vulnerabilities.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true
lookup_rfcUse this when the user asks about an RFC, such as "which RFC obsoletes RFC 2616?" or "find the RFC about WebSocket".No findings
Why it is in this group
- The name "lookup_rfc" says "lookup": a word for reading.
Description, as the server wrote it
Use this when the user asks about an RFC, such as "which RFC obsoletes RFC 2616?" or "find the RFC about WebSocket". Pass either the RFC number, or words from its title (not both). A number returns the title, status, publication date, authors, abstract, and the RFCs it obsoletes, is obsoleted by, updates and is updated by. Title words return up to five matching RFCs with their numbers: call again with a number for the details.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false
- idempotentHint: true
- openWorldHint: true

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.

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.
