How to integrate Dynamics365 MCP with Cursor

Cursor is one of the leading AI-powered code editors. It is built to help developers write, understand, and refactor code faster with AI assistance built directly into the editor.

And in this guide, I will explain the easiest and most secure way to connect your Dynamics365 account to Cursor via Composio Connect, so it can create a new sales lead for Acme Corp, list all open invoices for this quarter, add a support case for a specific customer, and more without ever putting your account credentials at risk.

Also integrate Dynamics365 with

Why Composio?

  • 1,000+ SaaS toolkits out of the box. Skip the work of building and maintaining integrations, Composio gives you instant access to a vast catalog of pre-built connectors.
  • One MCP server for every app. Connect any of your applications on demand through a single endpoint, rather than juggling a separate server for each app.
  • Smart, context-aware tool loading. Unlike traditional MCP servers that dump every available tool into the LLM context window, Composio searches for and loads only the tools relevant to the task at hand. A remote CLI workbench lets LLMs compose these tools into workflows for complex automation.

Connect Dynamics365 to Cursor

Two ways to install — pick whichever you prefer.

1. Install with one click

2. Or add manually

Add to your Cursor mcp.json

Open .cursor/mcp.json in your project root (or ~/.cursor/mcp.json for global config) and add the following configuration:

bash
{
  "servers": {
    "composio": {
      "type": "http",
      "url": "https://connect.composio.dev/mcp"
    }
  }
}

3. Authorize

Restart Cursor, then click "Connect" next to Composio in MCP Tools settings.

Connect your Dynamics365 account

Back in Cursor, ask the agent to connect to Dynamics365 or give it any Dynamics365-related task.

For example, ask it to:

  • "Create a new sales lead for Acme Corp"
  • "List all open invoices for this quarter"
  • "Add a support case for a specific customer"

It will prompt you to authenticate and authorize access to Dynamics365.

That is it. Composio tools are now available in Cursor, and your Dynamics365 account is ready to use.

FAQ

What are the differences in Tool Router MCP and Dynamics365 MCP?

With a standalone Dynamics365 MCP server, the agents and LLMs can only access a fixed set of Dynamics365 tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Dynamics365 and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Cursor?

Yes, you can. Cursor 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 Dynamics365 tools.

Can I manage the permissions and scopes for Dynamics365 while using Tool Router?

Yes, absolutely. You can configure which Dynamics365 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.

How safe is my data with Composio Tool Router?

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 Dynamics365 data and credentials are handled as safely as possible.
