What is Model Context Protocol (MCP)?

Model Context Protocol (MCP) is a standardized framework that allows Voice AI agents to connect with external tools and services. By integrating MCP servers, your agents gain the ability to perform actions beyond conversation, such as querying databases, triggering workflows, or accessing third-party APIs, based on the context of the interaction.

MCP acts as a bridge between your Voice AI agent and the tools it needs to deliver intelligent, automated responses. You define which tools are available and under what conditions they should be used, ensuring your agent operates with precision and relevance.

This integration is designed for businesses that want to extend their Voice AI capabilities with custom automation, real-time data access, and seamless integration with existing systems.

How to Enable MCP Support

MCP support is managed through the Labs section of your settings. Enabling this feature allows you to begin integrating MCP servers with your Voice AI agents.

Step 1Navigate to Labs Settings

Go to your settings and select the Labs section.

Step 2Find Voice AI - MCP Support

Locate the Voice AI - MCP Support feature in the Labs menu.

Step 3Enable the Feature

Toggle the feature on to activate MCP support for your Voice AI agents.

Success

Once enabled, you can proceed to add MCP servers and configure tools for your agents.

How to Add an MCP Server

After enabling MCP support, you can add custom MCP servers by providing their connection details. This allows your Voice AI agents to communicate with external tools and services.

Step 1Access MCP Server Configuration

Navigate to the MCP server management section within your Voice AI settings.

Step 2Enter Server Details

Provide the following information for your MCP server:

• MCP Name: A descriptive name for your server (for reference purposes)
• URL: The endpoint URL of your MCP server
• Headers: Authentication headers or other required HTTP headers
• Query Parameters: Optional parameters to include in server requests

Step 3Save Configuration

Save the server details to complete the setup. Your MCP server is available for use with Voice AI agents.

Important

Ensure your MCP server is properly configured and accessible. Invalid server details will prevent your agent from using the associated tools.

How to Configure MCP Tools for Your Voice AI Agent

Once an MCP server is added, you can configure which tools your Voice AI agent can access and define when those tools should be used during conversations.

Step 1Open Agent Setup

Navigate to your Voice AI agent's configuration settings.

Step 2Select MCP Tools

Choose which tools from your MCP server the agent can access. Only selected tools will be available for execution.

Step 3Define Execution Conditions

Describe when each tool should be used by specifying conditions based on conversation context. For example, a tool might trigger when a customer asks about pricing or requests an appointment.

Step 4Save Agent Configuration

Save your changes to apply the tool settings to your Voice AI agent.

Tip

Test your agent after configuring tools to ensure execution conditions trigger correctly and tools respond as expected.

Frequently Asked Questions

Q: What is Model Context Protocol (MCP)?Model Context Protocol (MCP) is a standardized framework that enables Voice AI agents to connect with external tools and services. It allows agents to perform actions such as querying databases, triggering workflows, or accessing APIs based on conversation context.Q: Do I need technical expertise to set up MCP?While MCP integration requires providing server configuration details, the setup process is straightforward. You enable the feature in Labs, enter your server URL and authentication headers, and select tools, no complex coding or programming is required.Q: Can I connect multiple MCP servers?Yes, you can add multiple MCP servers and manage tool access individually for each server, allowing your Voice AI agent to integrate with various external systems simultaneously.Q: How do I control which tools my agent can use?In your agent setup, you select specific tools from your MCP server and define execution conditions that determine when each tool should be triggered based on conversation context. This ensures precise control over agent behavior.Q: What happens if my MCP server becomes unavailable?If an MCP server is unreachable, the Voice AI agent will be unable to execute tools from that server. Ensure your server is reliable and accessible to maintain consistent agent functionality.Q: Can I test MCP tools before deploying my agent?Yes, you should test your agent after configuring MCP tools to verify that execution conditions trigger correctly and that tools respond as expected. This ensures a smooth experience when the agent is live.Q: Is MCP available for all users?MCP integration is available through Labs as an experimental feature. Enable it in your Labs settings to begin using MCP with your Voice AI agents. Features in Labs may be refined based on feedback.Need Help?
