spranab Brainstorm — Multi-Model AI Debates
Use the brainstorm-mcp tools to orchestrate structured debates between multiple LLMs. By default, Claude participates as an active debater alongside external models — reading their responses, pushing back, building on ideas, and refining its position across rounds.
When to Use
- User says "brainstorm this", "get multiple perspectives", "debate this topic"
- A question benefits from diverse viewpoints rather than a single model's answer
- User wants to compare how different models approach a problem
- Architecture decisions, trade-off analysis, or open-ended design questions
Tools
| Tool | Description |
|---|---|
brainstorm |
Run a multi-round debate between configured AI models |
brainstorm_respond |
Submit Claude's response for the current round of an interactive session |
list_providers |
Show all configured providers, models, and API key status |
add_provider |
Dynamically add a new AI provider at runtime |
Core Workflow (Interactive Mode — Default)
1. Start the debate
brainstorm({ topic: "Best architecture for a real-time app", rounds: 3 })
Returns round 1 external model responses + a session_id.
2. Respond each round
Read the external models' responses, form your own position, then call:
brainstorm_respond({ session_id: "<id>", response: "Your substantive contribution..." })
This stores your response and runs the next external round. Repeat until all rounds complete.
3. Synthesis
After the final round response, synthesis runs automatically and returns the full debate.
Non-Interactive Mode
For debates between external models only (no Claude participation):
brainstorm({ topic: "React vs Vue", participate: false })

Best Practices
- Use 2-3 rounds for quick opinions, 4-5 for deeper analysis
- Specify models explicitly when you want particular perspectives
- Use
systemPromptto focus the debate on specific aspects - Check
list_providersfirst to see which models are available - One model failing won't abort the debate — results are resilient
- Engage with other models' specific points — agree, disagree, build upon, or challenge
