Cortex MCP Server

Give AI coding agents the right context from your repository. Cortex builds a local map of your code, symbols, relationships, and project rules. Coding agents query that map through the CLI instead of guessing or reading the whole repository.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Cortex

Claude Code

claude mcp add danielblomma-cortex -- npx -y @danielblomma/cortex-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "danielblomma-cortex": {
      "command": "npx",
      "args": [
        "-y",
        "@danielblomma/cortex-mcp"
      ]
    }
  }
}

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