How do I install Hivemind?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Hivemind need an API key?

The publisher lists these environment variables: OPENAI_API_KEY, GOOGLE_API_KEY.

What transport does Hivemind use?

Hivemind runs locally over stdio.

When was Hivemind last checked?

Last checked 2026-10-16. Query multiple AI models (OpenAI, Anthropic, Google) for consensus responses.

Hivemind MCP server

Hivemind

Multi-model AI consensus platform that queries GPT-5.2, Claude Opus 4.5, and Gemini 3 Pro simultaneously to deliver synthesized, high-confidence responses.

MCP Server for Claude Code

Use Hivemind directly in Claude Code to get perspectives from GPT-5.2 and Gemini 3 Pro. Claude acts as the orchestrator and synthesizes the responses.

Requirements

Node.js >= 18
Claude Code CLI installed
At least one API key: OpenAI or Google AI

Note: No Anthropic API key needed - Claude is already your host!

Installation

npm install -g @quantulabs/hivemind
claude mcp add hivemind -- hivemind

Configuration

You need at least one API key, but both are recommended for better consensus:

OpenAI (GPT-5.2)
Google AI (Gemini 3 Pro)

Option 1: Paste directly (recommended)

/hive-config sk-proj-xxx...   # OpenAI key
/hive-config AIzaSy...        # Google key

Option 2: Config file

Create ~/.config/hivemind/.env:

OPENAI_API_KEY=sk-...
GOOGLE_API_KEY=AIza...

# Optional: Override default models
OPENAI_MODEL=gpt-5.1
GOOGLE_MODEL=gemini-2.5-flash

A .env.example template is included in the package.

For standalone MCP usage, you can also add an Anthropic key to include Claude in the consensus:

ANTHROPIC_API_KEY=sk-ant-...

Disable Claude Code mode via /hive-config > Settings > Claude Code Mode.

Usage

/hive "Why is my WebSocket connection dropping?"

Claude orchestrates the consensus from GPT-5.2 and Gemini 3 Pro responses.

Available Tools

Tool	Description
`hivemind`	Query models and get synthesized consensus
`configure_keys`	Set API keys (stored securely)
`check_status`	Check configuration and active providers
`configure_hive`	Toggle grounding search and settings
`check_stats`	View token usage and cost statistics

Claude Code Commands

/hive <question> - Orchestrate multi-model consensus with Claude as the synthesizer
/hive-config - Configure API keys and settings
/hivestats - View usage statistics

Automatic Hivemind Fallback

Copy CLAUDE.md.example to your project's .claude/CLAUDE.md to enable automatic Hivemind consultation when Claude is stuck (after 3+ failed attempts).

Prompt Caching

All providers use optimized caching for cost reduction on follow-up queries:

Provider	Type	Savings	Min Tokens
OpenAI	Automatic	50%	1024
Gemini 2.5+	Implicit	90%	-
Anthropic	Explicit	90%	1024

Web Interface

A full-featured web app with solo mode, hivemind mode, and conversation history.

Quick Start

# Clone the repository
git clone https://github.com/QuantuLabs/hivemind.git
cd hivemind

# Install dependencies (requires Bun >= 1.0)
bun install

# Start development server
bun dev

Open http://localhost:3000, click the settings icon, and enter your API keys.

Features

Multi-Model Consensus: Query 3 leading AI models simultaneously
Deliberation Algorithm: Up to 3 rounds of refinement to reach consensus
Solo Mode: Chat with individual models (GPT, Claude, Gemini)
Hivemind Mode: Get synthesized responses from all models
Conversation History: Persistent chat sessions
Dark/Light Theme: Full theme support
Secure Storage: API keys encrypted with AES-GCM in browser

Security

API keys are encrypted using AES-GCM with PBKDF2 key derivation
Keys are stored locally in browser localStorage (never sent to servers)
Session persistence uses sessionStorage (cleared on browser close)

How Consensus Works

Initial Query: All 3 models receive the same question
Analysis: An orchestrator analyzes responses for agreements/divergences
Refinement: If no consensus, models see other perspectives and refine (up to 3 rounds)
Synthesis: Final response synthesizes agreed points and addresses divergences

Supported Models

OpenAI

GPT-5.2 (default)
GPT-5.1, GPT-5, GPT-5 Mini, GPT-5 Nano
O4 Mini

Anthropic

Claude Opus 4.5 (default)
Claude Sonnet 4.5, Claude Opus 4, Claude Sonnet 4

Google

Gemini 3 Pro (default)
Gemini 3 Flash, Gemini 2.5 Pro/Flash/Flash Lite, Gemini 2.0 Flash
