MCP tools · 2 exposed · ~552 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
build_assistant_widget ~462

Turn a config into a ready-to-embed three.ws assistant widget, a floating 3D avatar chatbot you can drop onto any website. Returns a paste-ready <script> tag (with only the non-default settings as data-* attributes), a standalone frame URL for <iframe> embedding, an equivalent ThreeAssistant.init({...}) JavaScript-API snippet, the visual builder link, and the fully-normalized config. Pure and offline: every field is validated and clamped locally, so a bad value falls back to a safe default and the generated HTML is always well-formed. Call list_assistant_options first to see every avatar, background, mode and attribute you can set.

NameTypeReqDescription
accentstring–Accent "#hex" color for the widget UI. Default "#f97316". Non-hex values fall back to the default.
agentstring–A three.ws agent id to drive the assistant, as an alternative to picking an avatar directly.
avatarstring–Which avatar to show: a three.ws avatar id, a "/avatars/*.glb" path (e.g. "/avatars/selfie-girl.glb"), or a full GLB URL. Omit for the default mannequin.
backgroundstring–Backdrop behind the avatar: "transparent" (default), a "#hex" color, a preset (ember, ocean, violet, forest, dusk, slate), or "gradient:#aabbcc,#112233,160". Anything else falls back to transparent.
badgeboolean–Show the small "three.ws" attribution badge. Defaults to on.
contextstring–What the assistant should know about the site (used as its grounding context in chat).
greetingstring–Opening line the assistant shows on load.
modestring–Interaction mode: "chat" (text only), "speak" (voice only), or "both" (default).
namestring–Display name for the assistant / widget header.
positionstring–Which corner the launcher sits in: "right" (default) or "left".
voiceboolean–Start with voice on (true) or off (false). Defaults to on.

No examples provided.

list_assistant_options ~90

List everything you can configure on the three.ws assistant widget: the built-in avatars, background presets and grammar, interaction modes, chat lanes (free vs bring-your-own-key), and the full data-* attribute reference table. Call this before build_assistant_widget to know the vocabulary. Read-only and offline.

NameTypeReqDescription
filterstring–Optionally return just one section. Omit to get everything.
