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 870+ 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.
It will initiate the authentication in a browser window, authorize Codex to access your Composio account.
(Optional) Authenticate with OAuth
To authenticate manually, run the login command to open a browser window and authorize Codex to access your Composio account.
Verify the connection
Run codex mcp list to confirm Composio appears as a registered MCP server.
Codex App
Codex App follows the same approach as VS Code.
- Click ⚙️ on the bottom left → MCP Servers → + Add servers → Streamable HTTP:
- Fill the header and Key fields with
{ "x-consumer-api-key" = "ck_*******" }. - The Key is the Composio API key, that you can find on connect.composio.dev
- Click on Authenticate and authorize Codex to your Composio account and you're all set.
- Restart and verify if it's there in
.codex/config.toml
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.
