Enables Claude to query Grok as a peer for collaborative reasoning

grok-quorum-mcp

An MCP server that lets Claude query Grok as a quorum peer — enabling two AI systems to debate architecture, review code, and reason together before presenting solutions to the user.

Why a Quorum?

Single-AI workflows have blind spots. When Claude can consult Grok as an equal peer, you get:

  • Stronger code review — Two AI perspectives catch more bugs than one
  • Better architecture — Claude proposes, Grok challenges (or vice versa), you decide
  • Live research — Grok searches the web and X/Twitter in real-time for current information
  • Cost control — Four modes from cheap quick answers to expensive deep multi-agent analysis

Privacy & Security

  • Runs 100% locally — no telemetry, no analytics, no data collection
  • Your API key never leaves your machine except in direct calls to api.x.ai
  • Conversation history is in-memory only, cleared when the process exits
  • You supply your own xAI API key — we never see it

Installation

npm install -g grok-quorum-mcp

API Key Setup

You need an xAI API key. Get one at console.x.ai.

Option 1: Environment variable (recommended)

export XAI_API_KEY="xai-your-key-here"

Option 2: Key file

echo "xai-your-key-here" > ~/.xai_api_key
chmod 600 ~/.xai_api_key

Security note: Always use chmod 600 on the key file. The server will warn you if permissions are too open.

Configuration

Claude Code

Add to your ~/.mcp.json:

{
  "mcpServers": {
    "grok-quorum": {
      "command": "grok-quorum-mcp",
      "env": {
        "XAI_API_KEY": "xai-your-key-here"
      }
    }
  }
}

Claude Desktop

Add to your Claude Desktop MCP config:

{
  "mcpServers": {
    "grok-quorum": {
      "command": "npx",
      "args": ["-y", "grok-quorum-mcp"],
      "env": {
        "XAI_API_KEY": "xai-your-key-here"
      }
    }
  }
}

Modes

Mode Model Use Case Input/Output per 1M Timeout
fast grok-4-1-fast-reasoning Quick answers, simple questions $0.20 / $0.50 60s
code grok-4.20-0309-reasoning Precise code review with reasoning $2.00 / $6.00 2min
deep grok-4.20-multi-agent-0309 Multi-agent reasoning, architecture $2.00 / $6.00 5min
deep16 grok-4.20-multi-agent-0309 Maximum depth multi-agent analysis $2.00 / $6.00 10min

All models support 2M token context (2,000,000 tokens input) and 4M TPM rate limits.

Cost guidance: fast is 10x cheaper than the others. Use it for quick questions. code/deep/deep16 all use 4.20-class models at the same per-token rate — the difference is reasoning depth and multi-agent orchestration.

Tools

Tool Description
grok_query Query Grok with mode selection, optional context, and live search
grok_new_conversation Clear conversation history (use when switching topics)
grok_get_history View conversation state and approximate token usage
grok_get_last_response Recover raw API response — cost protection if parsing fails

Usage Examples

Quick question:

grok_query(message: "What's the best way to handle WebSocket reconnection?", mode: "fast")

Code review with context:

grok_query(
  message: "Review this for security issues and race conditions",
  context: "<file contents here>",
  mode: "code"
)

Architecture debate:

grok_query(
  message: "We're choosing between PostgreSQL and DynamoDB for our event store. Challenge my assumptions.",
  mode: "deep",
  new_conversation: true
)

Live research:

grok_query(
  message: "What are the latest MCP server best practices?",
  mode: "fast",
  search: "web"
)

Advanced Configuration

Override models via environment variables:

Variable Description Default
XAI_API_KEY xAI API key (required)
GROK_MODEL_FAST Model for fast mode grok-4-1-fast-reasoning
GROK_MODEL_CODE Model for code mode grok-4.20-0309-reasoning
GROK_MODEL_DEEP Model for deep/deep16 modes grok-4.20-multi-agent-0309
GROK_SYSTEM_PROMPT Custom system prompt (built-in)

Troubleshooting

Issue Fix
"No xAI API key found" Set XAI_API_KEY env var or create ~/.xai_api_key
Empty responses Run grok_get_last_response to inspect the raw API payload
Timeouts on deep mode Try fast mode first, or simplify the question
Model access errors Check your xAI plan supports the requested model
