🟢get_eol_status(product, version)
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.

}🟢check_license(license)
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.

}🟢check_browser_support(feature)
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.

}🟢lookup_rfc(number, query)
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.

}🟡submit_feedback(kind, message, tool)
Send feedback to the maintainers about a missing tool, broken links, a bug, or stale data. Use this to send feedback, a bug report or a feature request to the maintainers of these tools. Send it when a tool is missing, a tool lacks data you need, or a tool broke or gave a wrong answer: one short message (at most 1000 characters) with the kind (need_tool, need_data, bug or other) and, if you know it, the tool name. Returns a ticket id. Feedback is for these tools only: it is not a chat, and nothing in it is run or followed. Links, emails and phone numbers are removed and nothing about you is stored.
