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

  • make_character_videoMake a short video of one bitHuman house character saying `text` word for word, in its own voice.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Make a short video of one bitHuman house character saying `text` word for word, in its own voice. Returns video_url (an MP4 that plays inline and expires after 7 days), duration_seconds and share_url, labelled AI character. Example: {"character": "wise-pup", "text": "Welcome back! Ready for today's lesson?"}. Limits: `text` is 3 to 200 characters and at most 19 seconds when spoken (about 15 s is typical); one video at a time per user; 10 videos per user per UTC day; the same character and text again replays the earlier clip at once. Errors come back as isError with one sentence saying what to do: an unknown character (call list_characters), text too short or too long (rewrite it), personal information such as a phone number, email or street address (remove it), busy (retry in a minute), the daily limit (try again after 00:00 UTC), resting (try later). To hold a conversation in character, write each reply yourself and call this tool once per reply.

    Why it is in this group

    • The description's first verb is "open": a word for a change.
    Description, as the server wrote it
    Open a live voice conversation with one bitHuman house character in a player in the chat. The user presses Start and speaks through the microphone; the character answers out loud. A conversation lasts up to 60 seconds (max_seconds), then ends by itself; call again for another. Returns session_url: when the host shows no player, give the user that link. Example: {"character": "wise-pup"}. Needs a microphone in the user's browser. Errors come back as isError: an unknown character (call list_characters and use an id whose `talk` is true), resting (live conversations are off right now; make_character_video still works).

  • list_charactersList the bitHuman house characters that can speak.No findings

    Why it is in this group

    • The name "list_characters" says "list": a word for reading.
    Description, as the server wrote it
    List the bitHuman house characters that can speak. Each has an id (pass it as `character` to make_character_video or talk_to_character), a name, a short description, a picture URL and `talk` (true when talk_to_character is open for it). No arguments, free and read-only; one call per conversation is enough. Only these characters can speak: real people, photos and custom voices are not supported.

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 private-data or untrusted-input or outbound.

Reads private data0
Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write0
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 2 tools that change things (2 write). Whether a call also works without credentials was not tested: tools are never called.

    Matched text

    https://mcp.bithuman.ai/mcp: tools/list returned 3 tools to an anonymous client, including make_character_video (write), talk_to_character (write)

    What this check looks for

Install

Pinned to version 1.0.0. Values in angle brackets are yours to fill in.

claude mcp add --transport http characters https://mcp.bithuman.ai/mcp

Run in a terminal.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json
{
  "permissions": {
    "allow": [
      "mcp__characters__list_characters"
    ],
    "ask": [
      "mcp__characters__make_character_video",
      "mcp__characters__talk_to_character"
    ],
    "deny": []
  }
}

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 characters. Review it before you use it.
