Prerequisites

Recommended: Node.js 20+ (Node.js 18+ is supported).

Configuration

Add the following to your MCP client config, replacing <your-api-key> with the key you generated above.

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "agent-brains": {
      "command": "npx",
      "args": ["-y", "@agent-brains/mcp-client"],
      "env": {
        "AGENT_BRAINS_API_KEY": "<your-api-key>"
      }

  "mcpServers": {
    "agent-brains": {
      "command": "npx",
      "args": ["-y", "@agent-brains/mcp-client"],
