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.

What is the Capsule crm MCP server, and what's possible with it?
The Capsule crm MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Capsule CRM account. It provides structured and secure access to your contacts, sales opportunities, tasks, and more, so your agent can perform actions like managing contacts, tracking projects, organizing tasks, and retrieving sales data on your behalf.
- Contact and party management: Effortlessly create new contacts or organizations, list all parties, and even delete records when needed—all through your agent.
- Sales opportunity tracking: Retrieve lists of deleted or restricted sales opportunities and keep your pipeline data up to date with minimal manual work.
- Task and activity organization: List, search, and manage your Capsule tasks, notes, and completed activities to stay on top of daily work.
- Project and case monitoring: Quickly fetch all ongoing or filtered projects (cases) and review their status or details without ever opening the web app.
- Team and user management: List all users on your Capsule account or pull employees for a specific organization, making team reporting and auditing a breeze.
