How to Set Up and Use Brainstorm
Brainstorm MCP is a multi-model debate and ideation server that lets Claude orchestrate simultaneous conversations with GPT-4, Gemini, DeepSeek, Groq, and other AI models, then synthesize their responses into a structured verdict. It exposes tools for quick parallel perspective gathering, deep multi-round debates, and code review sessions where multiple models critique the same diff. Teams and solo developers use it to pressure-test architectural decisions, get diverse opinions on technical trade-offs, and surface blind spots that a single model might miss.
Prerequisites
- Node.js 18+ and npm installed
- An MCP-compatible client: Claude Desktop, Claude Code, or any MCP host
- At least one external provider API key: OPENAI_API_KEY, GEMINI_API_KEY, or DEEPSEEK_API_KEY (or use hosted mode with Claude only, which requires no extra keys)
- Optional: a BRAINSTORM_CONFIG JSON file if you want to configure multiple providers at once
Obtain provider API keys
Sign up for at least one external AI provider. OpenAI, Google Gemini, DeepSeek, and Groq are all supported. If you only want to use Claude-hosted models you can skip this step.
Add the server to your MCP client config
Edit your claude_desktop_config.json (or .mcp.json for Claude Code) to register brainstorm-mcp and pass your provider API keys as environment variables.
{
"mcpServers": {
"brainstorm": {
"command": "npx",
"args": ["-y", "brainstorm-mcp"],
"env": {
"OPENAI_API_KEY": "sk-...",
"GEMINI_API_KEY": "AIza...",
"DEEPSEEK_API_KEY": "sk-..."
}
}
}
}Restart your MCP client
Fully quit and reopen Claude Desktop (or reload the MCP host) so it picks up the new server registration.
Verify providers are configured
Ask Claude to call the list_providers tool to confirm which AI providers and models are available and which API keys are recognized.
Run your first brainstorm
Use the brainstorm_quick tool for fast parallel perspectives (under 10 seconds) or brainstorm for a full multi-round debate with synthesis. For code review, use brainstorm_review with a code diff.

}Prompts to try
Sample prompts that exercise different brainstorm tools.
- "Brainstorm the trade-offs between Redis and PostgreSQL for a job queue — use GPT and Gemini"
- "Quick perspectives from all configured models: should I use GraphQL or REST for a mobile API?"
- "Review this pull request diff for security issues and correctness using a red-team debate style"
- "Multi-round Socratic debate: is microservices architecture right for a team of 5 engineers?"Troubleshooting Brainstorm
list_providers shows no providers or all keys missing
Verify the API keys are set in the 'env' block of your MCP config, not as system environment variables. The server reads them from the config-provided environment, so they must appear in the JSON.
brainstorm_quick times out for one model but not others
The failing provider's API key may be invalid or the service may be rate-limiting you. Check the key in the relevant provider dashboard and ensure your account has active quota.
Server not found after adding config
Confirm the JSON is valid (no trailing commas, correct bracket nesting) and that you fully quit and restarted Claude Desktop rather than just closing the chat window.
