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.

$3

- 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!

$3

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

$3

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

Option 2: Config file

Create ~/.config/hivemind/.env:
`bash
OPENAI_API_KEY=sk-...
GOOGLE_API_KEY=AIza...
`

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

Using with other MCP clients (non-Claude Code)

For standalone MCP usage, you can also add an Anthropic key to include Claude in the consensus:
`bash
ANTHROPIC_API_KEY=sk-ant-...
`
Disable Claude Code mode via /hive-config > Settings > Claude Code Mode.


$3

`bash
/hive "Why is my WebSocket connection dropping?"
`

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

$3

| 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 |

$3

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

$3

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

$3

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.

$3

`bash


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.

$3

- 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

$3

- 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

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

Supported Models

$3

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