Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

alternatives

alternatives

Curated alternatives to a library, each with a one-line "prefer it when" and a verdict if the alternative is also indexed.

audit

audit_dependencies

Audit a project's dependencies for unmaintained packages, unstable APIs, and documented reasons to switch. Pass the contents of package.json, requirements.txt, or pyproject.toml. Returns only the dependencies worth a decision, not a report on every line. Run this before working in an unfamiliar codebase.

docs

docs_link

Official docs URL and GitHub repo for a library, one line each. Use when the clamped answers are not enough.

how

how_do_i

Return the 1-2 best code snippets for a task with a library, plus the gotcha for each. Snippets are correct for the indexed version. Far cheaper in tokens than a docs dump.

pick

pick_library

Given a coding task, recommend 1-3 libraries from the should-i-use index with one-line reasoning and an honest warning about the top pick. Use before installing anything.

should

should_i_use

Honest verdict on a specific library: 4-axis scores with reasons, when to skip it, and maintenance signals (last push, weekly downloads).

Should I Use — questions

Answers built from our own checks of this server.

What can Should I Use do?

It exposes 6 tools, read directly from the server on our last check. Among them: alternatives, audit_dependencies, docs_link, how_do_i, pick_library, should_i_use. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Should I Use working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 543 ms. The bar chart above shows every period we have measured.

How do I connect Should I Use?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Should I Use need an API key?

No. Should I Use completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Should I Use?

It answers our handshake in 543 ms on average, which is faster than 26% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

How many people use Should I Use?

The npm package should-i-use-mcp was installed 51 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.

Is Should I Use open source?

Yes — it is published under the MIT licence, written in JavaScript and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
