Tools

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

4 tools

Deletes or cancels 1Claude Code: deny
  • genmc_callCall any tool of the paired studio tab by name.No findings

    Why it is in this group

    • The name "genmc_call" says "call": a word for a change.
    • The server marks it destructive (destructiveHint: true).
    Description, as the server wrote it
    Call any tool of the paired studio tab by name. Use it when your tool list has not refreshed after pairing or after the user switched studios; otherwise call the tool directly.

    Annotations the server declares

    • title: Call a studio tool
    • readOnlyHint: false
    • destructiveHint: true
Changes things 1Claude Code: ask
  • genmc_pairConnect to the user's open genMC studio tab.No findings

    Why it is in this group

    • The input takes a statement or command to run (input.code), which can change anything it can reach.
    Description, as the server wrote it
    Connect to the user's open genMC studio tab. The user sees a code like "K7Q-4MX" after choosing "Connect agent" in the studio header. Pairing returns a resumeKey: if your MCP connection drops or restarts (an unknown session, a failed server), call genmc_pair with that resumeKey instead of asking the user for a new code. Resuming from another MCP session (a second client, a script) attaches it in addition: all your sessions reach the same tab. After pairing, the tab's WebMCP tools (skins, builds, whichever studio is open) appear in your tool list; if your client does not refresh it, use genmc_status and genmc_call.

    Why it is in this group

    • The description's first verb is "search": a word for reading.
    Description, as the server wrote it
    Search and read the genMC knowledge base: how every studio, tool, button, limit and workflow works (skins, builds, agents and pairing, accounts and sharing, export, shortcuts, troubleshooting). Call it without arguments for the table of contents, with query to search (best matching articles with a snippet and the matching section), or with article (a slug from the contents or a search result) to read one article in full as Markdown. Links written as doc:<slug> point to other articles. Use it when you are unsure how a feature works, what a label in the studio means, or how to explain something to the user. Read-only; it never changes the studio.

    Annotations the server declares

    • title: genMC knowledge base
    • readOnlyHint: true
    • destructiveHint: false
  • genmc_statusShow whether you are paired with a genMC studio tab, whether it is reachable, which studio page it shows and which tools it offers.No findings

    Why it is in this group

    • The name "genmc_status" says "status": a word for reading.
    Description, as the server wrote it
    Show whether you are paired with a genMC studio tab, whether it is reachable, which studio page it shows and which tools it offers. Call it when studio tools are missing from your tool list (the user switched studios): its answer also brings your tool list up to date.

    Annotations the server declares

    • title: genMC connection status
    • readOnlyHint: true
    • destructiveHint: false

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.
