Hivemind
Get agreement across OpenAI, Anthropic, and Google models before you commit to architecture, copy, or product decisions.
Overview
Hivemind is an MCP server for the Build phase that queries OpenAI, Anthropic, and Google models and returns consensus-style responses your agent can use in one call.
What is this MCP server?
- stdio MCP server (@quantulabs/hivemind v0.1.3) for multi-provider LLM queries
- Targets OpenAI (GPT-5.2 per env docs), Google Gemini, and Anthropic-style multi-model consensus
- Requires OPENAI_API_KEY and GOOGLE_API_KEY as secret env vars on the npm package
- Designed for aligned answers when one model might hallucinate or disagree
- npm registry transport—fits Claude Code, Cursor, and other MCP-capable agents
- Package version 0.1.3 on npm as @quantulabs/hivemind
- Documented env vars: OPENAI_API_KEY, GOOGLE_API_KEY (secrets)
- Transport: stdio per MCP server schema 2025-12-11

What problem does it solve?
Relying on one LLM for important product or code choices leaves you guessing when the model is wrong, biased, or overconfident.
Who is it for?
Indie builders who already use MCP daily and want cheap insurance on high-stakes prompts without building a custom multi-LLM router.
Skip if: Teams that only use one model with no API budget, or anyone who needs guaranteed factual verification rather than model agreement.
What do I get? / Deliverables
After you register Hivemind and add provider API keys, your agent can pull multi-model agreement on the same question inside your existing MCP workflow.
- Registered stdio MCP server exposing multi-model query tools to your agent
- Consensus-oriented responses aggregating major provider outputs for a shared prompt
- Repeatable in-IDE workflow without manual copy-paste across vendor chat UIs

Journey fit
Consensus querying is most often wired into the agent stack during build, even though the same tool supports earlier research and later ops judgment calls. Agent-tooling is the natural shelf because Hivemind is an MCP stdio server agents call—not a standalone app feature.
How it compares
MCP multi-LLM consensus integration, not a single-model skill or a curated skills marketplace.
Common Questions / FAQ
Who is Hivemind for?
Hivemind is for solo and small-team builders who run Claude Code, Cursor, Codex, or similar MCP clients and want OpenAI, Google, and Anthropic answers combined for tougher decisions.
When should I use Hivemind?
Use Hivemind when a single model’s answer affects scope, architecture, or copy and you want parallel provider queries before you ship or merge.
How do I add Hivemind to my agent?
Add the npm package @quantulabs/hivemind with stdio transport in your MCP config, set OPENAI_API_KEY and GOOGLE_API_KEY (and any Anthropic key your setup needs), then restart the agent so tools load.
