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 Minelead.io 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.

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

What is the Minelead.io MCP server, and what's possible with it?

The Minelead.io MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Minelead.io account. It provides structured and secure access to email discovery, verification, enrichment, lead records, and search history, so your agent can find professional emails, validate addresses, enrich contacts, research companies, and review saved leads on your behalf.

  • Professional email discovery: Have your agent find a person’s professional email using their name and company domain.
  • Company and social profile research: Direct your agent to search for known emails at one or several company domains, or find emails linked to a YouTube channel or Twitter/X profile.
  • Email validation and risk checks: Let the agent verify email format, mail records, mailbox status, personal-provider status, disposability, and spam signals before outreach.
  • Contact enrichment: Instruct your agent to enrich an email with available professional and social profile information.
  • Lead and research review: Have your agent list saved leads, review recent search history, or generate candidate company domains from keywords and locations.

Conclusion

You've successfully integrated Minelead.io with Codex using Composio's MCP server. Now you can interact with Minelead.io 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 Minelead.io 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:

FAQ

Frequently asked questions

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

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