    Why it is in this group

    • The name "ti4_list_factions" says "list": a word for reading.
    Description, as the server wrote it
    List all TI4 factions with colors, flags, and expansion info

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.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged outbound.

Reads private data5
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2
Brings in text someone else can write: web pages, inbound email, messages, issues and comments.
Can send data out0
Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

  • WarnThe whole server

    The endpoint served tools/list without credentials, and the list has 39 tools that change things (39 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://tools.moddable.games/mcp: tools/list returned 89 tools to an anonymous client, including chess_generate_puzzle (write), chess_make_move (write), chess_render_svg (write), chess_make_moves (write), hex_generate_map (write) and 34 more

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as moddable-games-tools. Review it before you use it.
