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.

How to install Icypeas MCP in Codex

Run the setup command

Run this command in your terminal to add the Composio MCP server to Codex.

Terminal

It will initiate the authentication in a browser window, authorize Codex to access your Composio account.

Composio authentication page

(Optional) Authenticate with OAuth

To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.

bash
codex mcp login composio

Verify the connection

Run codex mcp list to confirm Composio appears as a registered MCP server.

bash
codex mcp list

Codex App

Codex App follows the same approach as VS Code.

  1. Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
  2. Fill the header and Key fields with { "x-consumer-api-key" = "ck_*******" }.
  3. The Key is the Composio API key, that you can find on dashboard.composio.dev
  4. Click on Authenticate and authorize Codex to your Composio account and you're all set.

  1. Restart and verify if it's there in .codex/config.toml
bash

url = "https://connect.composio.dev/mcp"
http_headers = { "x-consumer-api-key" = "ck_*******" }

What is the Icypeas MCP server, and what's possible with it?

The Icypeas MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Icypeas account. It provides structured and secure access to professional email discovery and verification, so your agent can perform actions like finding emails, verifying addresses, searching company data, and scanning domains on your behalf.

  • Accurate email discovery and verification: Instantly find and verify professional email addresses using first name, last name, and company domain to supercharge your outreach or lead generation.
  • Bulk prospecting and search management: Launch bulk email or profile URL searches for thousands of contacts at once, then track progress and fetch results without manual oversight.
  • Comprehensive company and people lookup: Search for companies or filter people by name, title, company, and more to enrich your CRM or build targeted prospect lists efficiently.
  • Domain scanning for role-based emails: Scan entire company domains to discover all available role-based email addresses, simplifying large-scale contact discovery.
  • Subscription and usage insights: Check your Icypeas subscription details and remaining credits, helping you stay on top of your usage and plan outreach campaigns smarter.

Conclusion

You've successfully integrated Icypeas with Codex using Composio's MCP server. Now you can interact with Icypeas directly from your terminal, VS Code, or the Codex App using natural language commands.

Key benefits of this setup:

  • Seamless integration across CLI, VS Code, and standalone app
  • Natural language commands for Icypeas operations
  • Managed authentication through Composio
  • Access to 20,000+ tools across 1000+ apps for cross-app workflows
  • CodeAct workbench for complex tool chaining

Next steps:

  • Try asking Codex to perform various Icypeas operations
  • Explore cross-app workflows by connecting more toolkits
  • Build automation scripts that leverage Codex's AI capabilities

FAQ

Frequently asked questions

With a standalone Icypeas MCP server, the agents and LLMs can only access a fixed set of Icypeas tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Icypeas 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 Icypeas tools.

Yes, absolutely. You can configure which Icypeas 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 Icypeas data and credentials are handled as safely as possible.
