Spiderbrain MCP Server

A repo tells an AI agent what the code is. It never tells it what matters, what a change reaches, or why anything was built the way it was. So every agent re-derives the structure from scratch, every session, and gets it a little wrong.

People connecting coding agent tools to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

  "mcpServers": {
    "aabhisrv-spiderbrain.ai-coremind": {
      "url": "https://mcp.spiderbrain.ai/mcp"
    }
  }

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

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 · remote - your agent's requests go to mcp.spiderbrain.ai

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license MIT - declared in the repository

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

registry vendor namespace ai.spiderbrain - domain-verified with the official MCP registry
