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 Nocrm 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.

  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 Nocrm io MCP server, and what's possible with it?

The Nocrm 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 Nocrm io account. It provides structured and secure access to your lead management workflows, so your agent can create leads, assign owners, update statuses, tag and organize prospects, and manage teams automatically on your behalf.

  • Automated lead creation and tracking: Instantly add new leads to your pipeline and ensure they're properly assigned to the right users for follow-up.
  • Status and lifecycle management: Change lead statuses—like switching to 'standby' for scheduled follow-ups or marking leads as 'cancelled'—to keep your pipeline up to date.
  • Contextual lead updates: Append notes or tags to lead descriptions, helping sales teams capture every interaction and never lose important context.
  • Team and assignment coordination: Assign or reassign leads to users and fetch all teams and members, making it easier to distribute workload and manage ownership.
  • Lead duplication and cleanup: Effortlessly duplicate high-value leads for multi-step workflows, or permanently delete leads when they’re no longer needed, keeping your CRM organized.

Conclusion

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

  • Try asking Codex to perform various Nocrm io 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 Nocrm io MCP server, the agents and LLMs can only access a fixed set of Nocrm io tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Nocrm 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 Nocrm io tools.

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