How to integrate Jev 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 Jev account to Cursor via Composio Connect, so it can list available Jev models and versions, run a noul evaluation on model-x, compare two models using score questions, and more without ever putting your account credentials at risk.

Why Composio?

  • 1,500+ 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 Jev to Cursor

Two ways to install — pick whichever you prefer.

1. Install with one click

Click the button below to add Composio to Cursor.

↗Install in Cursor

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.

A browser window will open to authorize.

Connect your Jev account

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

For example, ask it to:

  • "List available Jev models and versions"
  • "Run a noul evaluation on model-x"
  • "Compare two models using score questions"

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

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

Conclusion

You have successfully connected Jev to Cursor using Composio Connect. Your agent can now use Jev securely without exposing credentials in prompts or local scripts.

FAQ

Frequently asked questions

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

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 Jev tools.

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