Three.ws Brain MCP Server

Three.ws Brain is an MCP integration. List LLM providers and run chat completions through the three.ws multi-provider router.

Packages and local setup

The published npm package is @three-ws/brain-mcp, version 0.1.3. Its declared MCP transport is stdio.

The package declares THREE_WS_BASE: Base URL of the three.ws API that fronts the LLM router (/api/brain/chat). Override only when self-hosting or targeting a preview deployment.; THREE_WS_API_KEY: Optional three.ws API key (sk_live_… / sk_test_…) or OAuth access token, sent as a Bearer token. Required only to use paid first-party flagships (Claude, GPT-5, o3, Grok, Qwen Plus, DeepSeek). Free open-weight tiers (GPT-OSS 120B, NVIDIA NIM models) work with no key. Create one at https://three.ws/dashboard/developers.; THREE_WS_TIMEOUT_MS: Per-request timeout in milliseconds. Chat completions stream server-side and are collapsed into a single reply, so this is generous by default to ride out a long flagship answer..

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
