ElevenLabs Integration

This server is specifically designed for ElevenLabs conversational agents. For detailed setup instructions, see ELEVENLABS-INTEGRATION.md.

⚠️ IMPORTANT: Before making any changes to this project, read PROJECT-STRUCTURE.md for critical deployment requirements and lessons learned.

Quick Start for ElevenLabs:

npm start

Then add http://localhost:3000/mcp to your ElevenLabs agent’s MCP server configuration.

Usage

Development Mode

Run the server:

npm start

Production Mode

Run the server:

npm start

Configuration

The server can be configured by modifying the following:

• Server name and version: Edit elevenlabs-true-streamable.js
• Tool implementations: Edit elevenlabs-true-streamable.js
• Tool schemas: Modify the schemas in elevenlabs-true-streamable.js

Note: This project uses a single-file approach for deployment reliability. All tools and schemas are hardcoded in the main server file.

Adding New Tools

To add a new tool:

1. Define the tool schema in elevenlabs-true-streamable.js:

{
  name: "new_tool",
  description: "Description of the new tool",
  inputSchema: {
    type: "object",
    properties: {
      parameter: { type: "string", description: "Description of the parameter" }
    },
    required: ["parameter"]
  }
}

2. Implement the tool handler in elevenlabs-true-streamable.js:

async function handleNewTool(args) {
  // Your tool implementation here
  return {
    content: [
      {
        type: "text",
        text: "Tool result",
      },
    ],
  };
}

3. Add the tool to the tools array and the handler to the switch statement in elevenlabs-true-streamable.js

Note: This project uses a single-file approach. All modifications should be made directly in elevenlabs-true-streamable.js.

case "new_tool":
  return await handleNewTool(args);

MCP Client Configuration
