@three-ws/brain-mcp
Any model, one interface — discover LLM providers and run chat completions through the three.ws multi-provider router, from any AI agent.
A Model Context Protocol server that gives any AI assistant the three.ws multi-provider LLM router over stdio. Discover which models are available — Claude, the GPT-5.6 family, o3, Grok, Qwen, DeepSeek, NVIDIA Nemotron, IBM Granite, and more — and run a chat completion through whichever one fits, without wiring each vendor SDK yourself.
The router fronts every provider behind one endpoint and transparently falls back across mirrors and free tiers if the chosen model is briefly down. The free open-weight tiers (GPT-OSS 120B, NVIDIA NIM models) work with no key; the paid first-party flagships unlock with a three.ws API key.

Questions
What is the brain-mcp MCP server?
Any model, one interface: the three.ws multi-provider LLM router over MCP. Discover available providers/models (Claude, GPT-5, Grok, Qwen, DeepSeek, NVIDIA Nemotron, IBM Granite and more) and run a chat completion through whichever one fits. Free tiers need no key; paid flagships unlock with a three
Is brain-mcp safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does brain-mcp need?
It reads THREE_WS_API_KEY from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.
How does brain-mcp run?
It speaks stdio, so it runs as a local process your client starts. It is published on npm as @three-ws/brain-mcp at 0.1.4.
How current is this page?
The grade is for one exact copy of the source (9899e9964390), read on 2026-10-10. The repository is watched and re-audited when it changes.
