You can do this in two different ways: - Via [Composio Connect](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code) - Direct and easiest approach - Via [Composio SDK](https://docs.composio.dev/docs?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=composio_sdk) - Programmatic approach with more control ## Also integrate Rocket reach with - [OpenAI Agents SDK](https://composio.dev/toolkits/rocket_reach/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/rocket_reach/framework/claude-agents-sdk) - [Claude Cowork](https://composio.dev/toolkits/rocket_reach/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/rocket_reach/framework/codex) - [OpenClaw](https://composio.dev/toolkits/rocket_reach/framework/openclaw) - [Hermes](https://composio.dev/toolkits/rocket_reach/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/rocket_reach/framework/cli) - [Google ADK](https://composio.dev/toolkits/rocket_reach/framework/google-adk) - [LangChain](https://composio.dev/toolkits/rocket_reach/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/rocket_reach/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/rocket_reach/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/rocket_reach/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/rocket_reach/framework/crew-ai) ## TL;DR - Only one MCP URL to connect multiple apps with Claude Code with zero auth hassles. - Programmatic tool calling allows LLMs to write its code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling. - Handling Large tool responses out of LLM context to minimize context rot. - Dynamic just-in-time access to 20,000 tools across 1000+ other Apps for cross-app workflows. It loads the tools you need, so LLMs aren't overwhelmed by tools you don't need. ## Connect Rocket reach to Claude Code ### Connecting Rocket reach to Claude Code using Composio 1. Add the Composio MCP to Claude ```bash claude mcp add --scope user --transport http composio https://connect.composio.dev/mcp ``` ## What is Claude Code? Claude Code is Anthropic's command line developer tool that lets you use Claude directly inside your terminal. Instead of switching between your editor, browser, and chat, you can stay in your project folder and ask Claude to help you build, debug, refactor, and understand code right where you're working. Key features include: - Terminal-Native Experience: Work with Claude directly in your command line without switching contexts - MCP Support: Built-in support for Model Context Protocol servers to extend Claude's capabilities - Project Context: Claude understands your project structure and can read, write, and modify files - Interactive Development: Ask questions, debug code, and get help in real-time while coding - Multi-Platform: Works on macOS, Linux, WSL, and Windows ## What is the Rocket reach MCP server, and what's possible with it? The Rocket reach MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your RocketReach account. It provides structured and secure access to professional contact information, so your agent can perform actions like finding verified emails, enriching lead profiles, searching for company details, and managing outreach research—all automatically on your behalf. - Find verified contact details: Instantly retrieve accurate email addresses, phone numbers, and social profiles for prospects or candidates from the RocketReach database. - Enrich and update lead profiles: Ask your agent to gather and supplement missing details about leads, including job titles, current companies, and social links. - Company lookup and research: Have your agent pull company background, industry, size, and key personnel information to inform outreach and targeting strategies. - List building and segmentation: Let your agent assemble lists of contacts based on filters like company, role, location, or industry, so you can streamline your outreach campaigns. - Contact verification and scoring: Direct your agent to check the deliverability and accuracy of contact details, helping you prioritize the best leads or candidates. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `ROCKET_REACH_CHECK_PERSON_STATUS` | Check Person Status | Tool to check the status of multiple person lookup requests.

It provides structured and secure access so Claude can perform Rocket reach operations on your behalf. With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster. ## Step-by-step Guide ### 1. Prerequisites Before starting, make sure you have: - Claude Pro, Max, or API billing enabled Anthropic account - Composio API Key - A Rocket reach account - Basic knowledge of Python or TypeScript ### 1. Install Claude Code To install Claude Code, use one of the following methods based on your operating system: ```bash # macOS, Linux, WSL curl -fsSL https://claude.ai/install.sh | bash # Windows PowerShell irm https://claude.ai/install.ps1 | iex # Windows CMD curl -fsSL https://claude.ai/install.cmd -o install.cmd && install.cmd && del install.cmd ``` ### 2. Set up Claude Code Open a terminal, go to your project folder, and start Claude Code: - Claude Code will open in your terminal - Follow the prompts to sign in with your Anthropic account - Complete the authentication flow - Once authenticated, you can start using Claude Code ```bash cd your-project-folder claude ``` ### 3. Set up environment variables Create a .env file in your project root with the following variables: - COMPOSIO_API_KEY authenticates with Composio (get it from [Composio dashboard](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=claude-code&utm_content=api_key&next=%2F~%2Forg%2Fconnect%2Fclients%2Fclaude-code)) - USER_ID identifies the user for session management (use any unique identifier) ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here ``` ### 4. Install Composio library No description provided. ```python pip install composio-core python-dotenv ``` ```typescript npm install @composio/core dotenv ``` ### 5. Generate Composio MCP URL No description provided. ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["rocket_reach"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http rocket_reach-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['rocket_reach'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http rocket_reach-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ### 6. Run the script and copy the MCP URL No description provided. ```python python generate_mcp_url.py ``` ```typescript node --loader ts-node/esm generate_mcp_url.ts # or if using tsx tsx generate_mcp_url.ts ``` ### 7. Add Rocket reach MCP to Claude Code In your terminal, add the MCP server using the command from the previous step. The command format is: - claude mcp add registers a new MCP server with Claude Code - --transport http specifies that this is an HTTP-based MCP server - The server name (rocket_reach-composio) is how you'll reference it - The URL points to your Composio Tool Router session - --headers includes your Composio API key for authentication After running the command, close the current Claude Code session and start a new one for the changes to take effect. ```bash claude mcp add --transport http rocket_reach-composio "YOUR_MCP_URL_HERE" --headers "X-API-Key:YOUR_COMPOSIO_API_KEY" # Then restart Claude Code exit claude ``` ### 8. Verify the installation Check that your Rocket reach MCP server is properly configured. - This command lists all MCP servers registered with Claude Code - You should see your rocket_reach-composio entry in the list - This confirms that Claude Code can now access Rocket reach tools If everything is wired up, you should see your rocket_reach-composio entry listed: ```bash claude mcp list ``` ### 9. Authenticate Rocket reach The first time you try to use Rocket reach tools, you'll be prompted to authenticate. - Claude Code will detect that you need to authenticate with Rocket reach - It will show you an authentication link - Open the link in your browser (or copy/paste it) - Complete the Rocket reach authorization flow - Return to the terminal and start using Rocket reach through Claude Code Once authenticated, you can ask Claude Code to perform Rocket reach operations in natural language. For example: - "Find verified email for LinkedIn profile" - "Get direct dial number for company executive" - "Lookup job title for specific contact" ## Complete Code ```python import os from composio import Composio from dotenv import load_dotenv load_dotenv() COMPOSIO_API_KEY = os.getenv("COMPOSIO_API_KEY") USER_ID = os.getenv("USER_ID") composio_client = Composio(api_key=COMPOSIO_API_KEY) composio_session = composio_client.create( user_id=USER_ID, toolkits=["rocket_reach"], ) COMPOSIO_MCP_URL = composio_session.mcp.url print(f"MCP URL: {COMPOSIO_MCP_URL}") print(f"\nUse this command to add to Claude Code:") print(f'claude mcp add --transport http rocket_reach-composio "{COMPOSIO_MCP_URL}" --headers "X-API-Key:{COMPOSIO_API_KEY}"') ``` ```typescript import 'dotenv/config'; import { Composio } from '@composio/core'; const { COMPOSIO_API_KEY, USER_ID } = process.env; if (!COMPOSIO_API_KEY || !USER_ID) { throw new Error('COMPOSIO_API_KEY and USER_ID required in .env'); } const composioClient = new Composio({ apiKey: COMPOSIO_API_KEY }); const composioSession = await composioClient.create(USER_ID, { toolkits: ['rocket_reach'], }); const composioMcpUrl = composioSession?.mcp.url; console.log(`MCP URL: ${composioMcpUrl}`); console.log(`\nUse this command to add to Claude Code:`); console.log(`claude mcp add --transport http rocket_reach-composio "${composioMcpUrl}" --headers "X-API-Key:${COMPOSIO_API_KEY}"`); ``` ## Conclusion You've successfully integrated Rocket reach with Claude Code using Composio's MCP server.

With a standalone Rocket reach MCP server, the agents and LLMs can only access a fixed set of Rocket reach tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Rocket reach and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Claude Code? Yes, you can. Claude Code fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Rocket reach tools. ### Can I manage the permissions and scopes for Rocket reach while using Tool Router? Yes, absolutely. You can configure which Rocket reach scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do. ### How safe is my data with Composio Tool Router? All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Rocket reach data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
