Should I Use tools (6)

write = sends, deletes, buys or posts
  • alternativesFree

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

  • audit_dependenciesFree

    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_linkFree

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

  • how_do_iFree

    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_libraryFree

    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_i_useFree

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

What the publisher says

From the Should I Use repository's README, as published. We do not edit it. Read it on GitHub

should-i-use

The MCP that tells your agent what NOT to install.

Most library docs MCP servers dump thousands of tokens of documentation into your context and let the model sort it out. This one answers the actual question: which library to pick, which to skip, and how to do the thing. Typical answers run 25 to 360 tokens. Every response is hard-clamped at 500.

992 libraries indexed. Last updated: 2026-08-16.

The index grows daily. Data comes from a curated set of npm and PyPI libraries with honest guides written to a fixed rubric and grounded in each library's own docs: what a library is actually like to set up, when you should not use it, verified alternatives, 4-axis scorecards, and version-correct code snippets. If a library is not indexed, the tools say so plainly instead of guessing.

If you want a Context7 alternative that treats context as a budget rather than a bucket, this is it.

Quickstart

No API key, no database. The index ships inside the package.

npx should-i-use-mcp install

That writes the server entry into whichever agent configs already exist on your machine: Claude Code, Claude Desktop, Cursor, Windsurf, Cline, VS Code, Zed, Codex, Gemini CLI. Each file it touches is backed up as .bak first. Restart your agent afterwards.

For a repo-local config instead of your home directory:

npx should-i-use-mcp install --project

That writes .mcp.json and .cursor/mcp.json in the current directory, so everyone who clones the repo gets the server.

Claude Code, one line

claude mcp add should-i-use -- npx -y should-i-use-mcp

By hand

If you would rather edit the JSON yourself, add this to your client's MCP config (~/.cursor/mcp.json for Cursor, ~/.codeium/windsurf/mcp_config.json for Windsurf, the Claude Desktop config on macOS or Windows, and so on):

{
  "mcpServers": {
    "should-i-use": {
      "command": "npx",
      "args": ["-y", "should-i-use-mcp"]
    }
  }
}

Any other MCP client: command npx, args ["-y", "should-i-use-mcp"]. Running from a local checkout: command node, args ["/path/to/should-i-use/server.js"]. VS Code puts the same object under servers instead of mcpServers, and Zed under context_servers; the installer handles both.

Hosted endpoint (rolling out)

A hosted streamable-HTTP endpoint is rolling out at https://mrkeyoor.com/mcp. It serves the live index, so it can be a day fresher than the npm snapshot. The npx install above is the stable path today.

Tools

audit_dependencies

The pitch is "ask before you npm install". This is the tool for the codebase you did not write, where the installing already happened.

Shortened. The full README is on GitHub.

Should I Use: common questions

Is Should I Use MCP server safe?
Yes, by our scan: it is graded A (85/100). Read the Should I Use safety report
How do I install Should I Use?
It runs remotely at mrkeyoor.com. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
Does Should I Use need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Should I Use maintained?
The last commit was 80 days ago (2026-08-16). The latest release is v0.3.2.
Is Should I Use up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Should I Use?
Servers from other publishers that do the same job: Serena MCP: the IDE for your agent MCP server, Figma Context MCP server and Commonly MCP server.
How does Should I Use compare with other AI and agents MCP servers?
safety score 85/100 (higher than 73% of 4,460 AI and agents servers); tools 6 (the typical AI and agents server has 6); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
