Claude Code, Anthropic's AI-powered coding assistant, has gained the ability to connect directly to external services like HeyGen (an AI video creation platform) and search APIs through a new integration layer called Composio. This means developers can now ask Claude Code to create talking photos, manage video projects, and retrieve real-time search results without leaving their terminal or code editor. The integration uses the Model Context Protocol (MCP), a standardized way for AI agents to access external tools securely.

What Can Claude Code Actually Do With These New Integrations?

The HeyGen integration opens up several practical capabilities for developers building video-related workflows. Developers can now ask Claude Code to perform tasks that previously required switching between multiple applications.

• Dynamic Talking Photo Generation: Convert static images into interactive speaking content by uploading photos and letting Claude Code generate talking avatars on your behalf, useful for marketing or educational content creation.
• Personalized Video Project Management: Add contacts to video projects and retrieve detailed project information at scale, streamlining large-scale video personalization efforts without manual intervention.
• Real-Time Avatar Streaming Control: Retrieve lists of available streaming avatars, generate streaming tokens, and manage live avatar sessions, including the ability to interrupt or monitor ongoing streams for responsive interactions.
• AI-Powered Video Asset Creation: Add new avatars, backgrounds, or other content elements directly into your HeyGen library for use in video generation workflows.
• Audience Insights and Analytics: Fetch detailed audience engagement and preference data for personalized video campaigns to optimize content and targeting strategies.

The search API integration is similarly practical. Developers can ask Claude Code to retrieve top Google search results, extract featured snippets from web pages, or pull recent news headlines about specific topics, all without opening a browser.

How to Connect Claude Code to HeyGen and Search APIs?

The setup process involves generating a special URL through Composio, a universal gateway that handles authentication and tool management. Here's what developers need to do:

• Install Claude Code: Use the command line to install Claude Code on macOS, Linux, or Windows, then authenticate with your Anthropic account.
• Set Up Composio Credentials: Create a.env file with your Composio API key and a unique user ID, then install the Composio TypeScript library using npm.
• Generate the MCP URL: Run a TypeScript script that connects to Composio and creates a Tool Router session for the service you want (HeyGen or Search API), which outputs a special MCP URL.
• Register the MCP Server: Use the command "claude mcp add" in your terminal to register the MCP server with Claude Code, including the URL and your Composio API key as a header.
• Authenticate and Start Using: Restart Claude Code, and the first time you try to use the integrated service, you'll be prompted to authorize access through your browser.

Once set up, developers can use natural language commands. For example, asking Claude Code to "create a talking photo from my selfie" or "list all available streaming avatars for today" will trigger the appropriate HeyGen actions.

Why Does This Matter for Developers?

The integration addresses a growing pain point in AI-powered development: managing authentication and API access across multiple tools. Composio handles OAuth tokens, API key rotation, and security concerns, so developers don't have to manually manage credentials or worry about breaking API changes. This is particularly important as development workflows become more complex and involve more external services.

The broader context matters here. DXC Technology, a major enterprise software company, recently announced that its development platform "DXC OASIS" now has over 95% of its code generated by Claude before human review, accelerating development velocity by an estimated 10x. As Claude becomes more deeply embedded in production workflows, the ability to connect it to specialized services like video platforms and search engines becomes increasingly valuable for teams building at scale.

The dual-pool approach to tool management is also noteworthy. Composio's MCP implementation loads only the tools developers actually need, preventing Claude Code from being overwhelmed by irrelevant options. This reduces context bloat and improves response times, a critical consideration as AI agents handle more complex, multi-step tasks.

For teams managing Claude Code across multiple engineers, the combination of managed authentication and precise tool access represents a step toward more predictable, secure, and scalable AI-assisted development workflows. The integration is live as of June 2026 and available to Claude Pro, Max, and API billing users.
