A Compatible MCP Client. I recommend Claude Desktop

Installation

via Smithery

To install ChainGPT MCP Server for any MCP client automatically via Smithery:

npx -y @smithery/cli install @kohasummon/chaingpt-mcp --client claude

This adds the server to claude desktop config. Replace claude with the name of the client you are using. See the list of clients here.

Manual Installation

pnpm install -g @kohasummon/chaingpt-mcp

Configure Claude Desktop to recognize the ChainGPT MCP server

You can find claude_desktop_config.json inside the settings of Claude Desktop app:

Open the Claude Desktop app and enable Developer Mode from the top-left menu bar.

Once enabled, open Settings (also from the top-left menu bar) and navigate to the Developer Option, where you'll find the Edit Config button. Clicking it will open the claude_desktop_config.json file, allowing you to make the necessary edits.

OR (if you want to open claude_desktop_config.json from terminal)

For macOS:

code ~/Library/Application\ Support/Claude/claude_desktop_config.json

For Windows:

code %APPDATA%\Claude\claude_desktop_config.json

2. Add the ChainGPT MCP server configuration:

{
  "mcpServers": {
    "chaingpt": {
      "command": "npx",
      "args": ["/path/to/chaingpt-mcp/build/index.js"],
      "env": {
        "CHAINGPT_SECRET_KEY": "your-secret-key-here"
      },
      "toolCallTimeoutMillis": 120000
    }
  }
}

Replace your-secret-key-here with your actual ChainGPT secret key from app.chaingpt.org/apidashboard.

3. Restart Claude Desktop

For the changes to take effect:

Completely quit Claude Desktop (not just close the window)
Start Claude Desktop again
Look for the 🔌 icon to verify the ChainGPT MCP server is connected
