Brainstorm MCP

Ask one model a design question and you get one confident answer, with no signal about which parts it is unsure of. Ask three and the disagreement is the signal. Its 7 documented tools cluster into brainstorm, read & search, create & write. It runs locally over stdio via the published package.

People who work with ai debate, brainstorming and deepseek and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Brainstorm MCP

before you install - you'll need

Set OPENAI_API_KEY, GEMINI_API_KEY, DEEPSEEK_API_KEY before connecting.

Claude Code

claude mcp add spranab-brainstorm-mcp -- npx -y brainstorm-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "spranab-brainstorm-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "brainstorm-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

license MIT - declared in the repository

npm package brainstorm-mcp - unscoped; check the name against the project README before installing

registry namespace io.github.spranab is GitHub-verified and matches the repo owner

Tools grouped from the project's README - what Brainstorm MCP lets an agent do.

Brainstorm

5 tools - e.g. Multi-round debate between AI models (API or hosted mode); Instant multi-model perspectives - parallel, no rounds; Multi-model code review with findings, severity, verdict
