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 connecting AI & ML tools to 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

02 · Evidence

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

03 · What Brainstorm MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 7 documented tools across brainstorm, read & search, create & write, including brainstorm, brainstorm_quick, brainstorm_review, brainstorm_respond.

Capability map

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

brainstorm · brainstorm_quick · brainstorm_review · brainstorm_respond · brainstorm_collect

read & search

1 tool - e.g. Show configured providers, API key status, and detected CLIs

list_providers

create & write

1 tool - e.g. Add a new API or CLI provider at runtime

add_provider
