Claude Code can now tap into Exa, a web data extraction and search platform, through a new integration that handles authentication automatically. Developers can now ask Claude Code to summarize recent news articles, find semantically similar research papers, create data collections, and monitor web content using natural language commands, all without wrestling with API keys or OAuth flows.

The integration works through Composio, a platform that acts as a universal gateway between AI coding assistants and external tools. Rather than forcing developers to manually manage authentication tokens and API credentials, Composio handles the OAuth handshake, token refresh, and permission scopes behind the scenes. This means you can focus on building workflows instead of debugging authentication errors.

What Can You Actually Do With Exa and Claude Code Together?

Once connected, Claude Code gains access to Exa's capabilities through natural language prompts. Instead of writing complex API calls, you can simply tell Claude Code what you need, and it translates your request into the appropriate Exa operations. The platform supports several practical use cases:

• Citation-backed research: Ask Claude Code to summarize recent news articles on a topic like AI safety, and Exa returns direct answers with source citations so you know where the information came from.
• Semantic similarity search: Find web pages or research documents that are conceptually related to a URL you provide, complete with highlighted excerpts and summaries for context.
• Data import and webset management: Let Claude Code create, configure, or delete data collections (called websets) to streamline how you gather and organize information from the web.
• Automated monitoring: Schedule monitors for your data collections so they stay fresh and up-to-date with minimal manual intervention.
• Event tracking: Access a full history of system events or retrieve details for specific activities within your Exa environment.

The integration also supports what's called "programmatic tool calling," which means Claude Code can write code in a remote workbench to handle complex chains of operations. This reduces the back-and-forth between you and the AI when you need to perform multiple steps in sequence. Additionally, Composio handles large tool responses outside of the AI's context window, which prevents the AI from getting overwhelmed by too much information at once.

How to Connect Exa to Claude Code in Your Project?

Setting up the integration requires a few steps, but the process is designed to be straightforward for developers with basic knowledge of Python or TypeScript:

• Install Claude Code: Use the command line installer for your operating system (macOS, Linux, Windows, or WSL), then run "claude" in your project folder and authenticate with your Anthropic account.
• Set up environment variables: Create a.env file in your project root with your Composio API key and a user ID for session management. You'll need a Composio API key from the Composio dashboard and a Exa account.
• Install the Composio SDK: Run npm to install the @composio/core library and dotenv package, which provides the underlying technology for creating secure MCP (Model Context Protocol) connections.
• Generate an MCP URL: Write a TypeScript script that uses the Composio client to create a Tool Router session for Exa. This script generates a unique MCP URL that Claude Code will use to access Exa's tools.
• Register the MCP server: Run the "claude mcp add" command with your generated URL and API key to register Exa as an MCP server in Claude Code. Then restart Claude Code to apply the changes.
• Verify the connection: Run "claude mcp list" to confirm that your exa-composio entry appears in the list of registered servers.
• Authenticate with Exa: The first time you use Exa tools, Claude Code will prompt you with an authentication link. Complete the authorization flow in your browser, and you're ready to start using Exa operations.

Once everything is wired up, you can start using Exa through Claude Code by typing natural language commands directly in your terminal. For example, you might ask Claude Code to "summarize recent news articles on AI safety" or "find similar research papers to this URL" or "create a webset for quarterly sales data." Claude Code translates these requests into Exa operations and returns the results.

Why Does This Matter for Developers?

The Exa integration addresses a real friction point in AI-assisted development: managing external tool connections. Traditionally, connecting Claude Code to a third-party service like Exa meant handling OAuth flows, storing API keys securely, managing token expiration, and debugging authentication failures. Composio abstracts all of that away, letting developers focus on the actual task they're trying to accomplish.

The integration also demonstrates how Claude Code is evolving beyond code generation into a more general-purpose AI assistant for development workflows. By connecting to Exa, developers can now perform research, data gathering, and monitoring tasks directly from their coding environment without switching between multiple tools. This is particularly valuable for teams building applications that need to ingest, analyze, or monitor web-based data.

Composio's approach of managing authentication centrally also reduces security risks. Rather than scattering API keys across multiple projects and developers' machines, credentials are stored and managed in one place, with access controlled through Composio's infrastructure. This makes it easier for teams to audit who has access to what and rotate credentials when needed.
