Findings

Matches of fixed checks, with the text they matched.

1 warn
  • Warnfind_alternatives

    The server marks "find_alternatives" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".

    Matched text

    annotations: {"readOnlyHint":true,"destructiveHint":false,"idempotentHint":true,"openWorldHint":false}; The name "find_alternatives" says "find": a word for reading.

Tools

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

    Why it is in this group

    • The name "find_alternatives" says "find": a word for reading.
    • The description's first verb is "open": a word for a change.
    • The input addresses people (input.to): what it sends cannot be taken back.
    • 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
    Open-source alternatives to an app, product or service ("Photoshop", "Notion", "Heroku", "Postman"), from the GitHub repos RepoAlerts tracks, with real star counts and growth. Optionally for a platform or constraint ("Mac", "self-hosted"). Repos whose own page lists that app as something they replace come first.

    Why it is in this group

    • The name "get_repo" says "get": a word for reading.
    Description, as the server wrote it
    Everything RepoAlerts knows about one GitHub repository (owner/name or URL): what it is and who it's for, stars and recent growth, a summary of its star curve, licence, last push, the apps it can replace, Hacker News stories and similar repos. Use it to check a repo before recommending or installing it. If the repo isn't in the directory, it says so (it may be unknown or excluded for fake stars).

    Why it is in this group

    • The name "search_repos" says "search": a word for reading.
    Description, as the server wrote it
    Find real, actively growing open-source GitHub repositories for a need described in plain words ("a calendar MCP server", "free Photoshop alternative for Mac", "self-hosted analytics"). Semantic search over the RepoAlerts directory, which leaves out repos with fake (bought or farmed) stars. Use it instead of recalling package or repo names from memory, whenever the user asks for a tool, library, app, framework or MCP server. Returns for each repo: what it is, who it's for, stars and stars gained in 24 hours and 7 days, licence, last push, its RepoAlerts page and GitHub URL.

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.
