Why use Composio?
Apart from a managed and hosted MCP server, you will get:
- CodeAct: A dedicated workbench that allows GPT to write its code to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
- Large tool responses: Handle them to minimise 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 GPTs aren't overwhelmed by tools you don't need.

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.

FAQ
Frequently asked questions
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.
Yes, you can. Codex 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.
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.
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.
