Smallest MCP Server

MCP server for the Smallest AI platform. Manage agents, debug calls, view analytics — directly from your IDE.

Quick start

Requires Node.js 18+. Add this to your MCP config (~/.cursor/mcp.json for Cursor, claude_desktop_config.json for Claude Desktop):

{
  "mcpServers": {
    "smallest": {
      "command": "npx",
      "args": ["-y", "@developer-smallestai/smallest-mcp-server"],
      "env": {
        "ATOMS_API_KEY": "sk_your_key_here"
      }
    }
  }
}

Auto-updates to the latest version every time your editor restarts.

Option B: One-line installer (no dependencies)

Mac / Linux:

curl -fsSL https://raw.githubusercontent.com/smallest-inc/mcp-server/main/install.sh | bash

Windows (PowerShell):

irm https://raw.githubusercontent.com/smallest-inc/mcp-server/main/install.ps1 | iex

Downloads a standalone binary, prompts for your API key, and configures Cursor + Claude Desktop automatically. Re-run to update.

Option C: One prompt

Open a chat in Cursor or Claude Desktop and type:

Set up the Smallest MCP server for me.
The npm package is @developer-smallestai/smallest-mcp-server.
My API key is: sk_paste_your_key_here

Verify

Reload your editor, then type: "List all my agents"
