• Voice-Activated Command Execution: Execute complex commands within Cursor using voice commands, eliminating the need for manual typing and mouse clicks. This can streamline workflows and improve overall productivity.

• AI Assistant Integration: Interact with Vapi’s AI assistants directly within Cursor, leveraging their knowledge and expertise to solve problems, answer questions, and generate code snippets. This provides developers with instant access to AI-powered support, enhancing their ability to tackle challenging tasks.

• Hands-Free Navigation: Navigate through code files and directories using voice commands, allowing developers to quickly find the information they need without interrupting their workflow.

Setting Up the Vapi MCP Server: A Step-by-Step Guide

Setting up the Vapi MCP server involves a few key steps, including configuring environment variables, building the server, and integrating it with Cursor. The following guide provides a detailed walkthrough of the entire process:

1. Project Setup:

• Ensure you have the necessary prerequisites installed, including Node.js and npm (Node Package Manager).
• Clone the Vapi MCP server repository from GitHub.
• Navigate to the vapi-mcp-server directory.

2. Environment Configuration:

• Create a .env file in the vapi-mcp-server directory.
• Add the following environment variables to the .env file, replacing the placeholders with your actual Vapi API keys:

Vapi API Keys

VAPI_ORG_ID=your-org-id VAPI_PRIVATE_KEY=your-private-key VAPI_KNOWLEDGE_ID=your-knowledge-id VAPI_JWT_PRIVATE=your-jwt-private

Environment

NODE_ENV=development

3. Building the Server:

• Run the following commands in the vapi-mcp-server directory to install dependencies and build the server:

bash npm install npm run build

4. Configuring Cursor:

• Open Cursor and navigate to the MCP settings.
• Add a new MCP configuration for the Vapi MCP server.
• Use the following configuration, replacing the placeholders with the correct paths and API keys:

“Vapi Voice AI Tools”: { “command”: “node”, “type”: “stdio”, “args”: [ “/Users/matthewcage/Documents/AA-GitHub/MCP/vapi-mcp/vapi-mcp-server/dist/index.js” ], “cwd”: “/Users/matthewcage/Documents/AA-GitHub/MCP/vapi-mcp/vapi-mcp-server”, “env”: { “VAPI_ORG_ID”: “your-org-id”, “VAPI_PRIVATE_KEY”: “your-private-key”, “VAPI_KNOWLEDGE_ID”: “your-knowledge-id”, “VAPI_JWT_PRIVATE”: “your-jwt-private”, “NODE_ENV”: “development” } }

• Important: Ensure that the cwd parameter is set correctly to the vapi-mcp-server directory, and that all required environment variables are explicitly provided in the configuration.

Troubleshooting Common Issues

While the setup process is generally straightforward, you may encounter some common issues. Here are some troubleshooting tips to help you resolve them:

• “Client Closed” Error: This error typically indicates a problem with the server’s configuration or environment. Ensure that the cwd parameter is set correctly, that all required environment variables are passed in the configuration, and that the package.json file includes "type": "module".

• “Module Not Found” Error: This error usually occurs when the server is unable to find the required modules. Double-check that you are running the server from the correct directory, that you have rebuilt the project with npm run build, and that all dependencies are installed with npm install.

• Permissions Issues: Make sure the dist/index.js file is executable. You can use the command chmod +x dist/index.js to grant execute permissions.

Available Tools: Leveraging Vapi’s Voice AI Capabilities

The Vapi MCP server provides access to a range of powerful tools that enable you to leverage Vapi’s voice AI capabilities within Cursor:

• vapi_call: Make outbound calls using Vapi’s voice AI. This tool allows you to initiate calls to external numbers and interact with recipients using Vapi’s advanced voice synthesis and recognition technologies.

• vapi_assistant: Manage voice assistants. This tool provides a comprehensive set of functionalities for creating, retrieving, listing, updating, and deleting voice assistants. You can use it to customize the behavior and capabilities of your AI assistants.
