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 1500+ 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 Zoho MCP in Codex

The Zoho MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Zoho account. It provides structured and secure access to your Zoho CRM data, so your agent can create contacts and leads, manage deals, search records, track activities, and draft emails on your behalf.
- Contact and lead management: Have your agent create contacts and leads, find existing records, and review prospect details in Zoho CRM.
- Deal and account tracking: Let the agent create and update deals, review sales opportunities, search accounts, and update account details.
- Tasks, calls, and event coordination: Direct your agent to find tasks, review logged calls, create events, and check upcoming meetings.
- Notes, emails, and attachments: Instruct your agent to add notes to CRM records, review related emails and attachments, and prepare email drafts.
- CRM record discovery: Have your agent search across Zoho CRM modules, list available modules, and retrieve related records for added context.

FAQ
Frequently asked questions
With a standalone Zoho MCP server, the agents and LLMs can only access a fixed set of Zoho tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Zoho 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 Zoho tools.
Yes, absolutely. You can configure which Zoho 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 Zoho data and credentials are handled as safely as possible.
