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 your Virustotal account

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

For example, ask it to:

  • "Scan this file hash for malware"
  • "Get analysis report for suspicious URL"
  • "Retrieve domain reputation details"

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

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

Conclusion

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

FAQ

Frequently asked questions

With a standalone Virustotal MCP server, the agents and LLMs can only access a fixed set of Virustotal tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Virustotal 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 Virustotal tools.

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

A lot of students tell us that the moment their connected tools start talking to each other inside Opennote feels almost magical. The agent just knows them, and it's immensely helped keep new users on the platform.

We chose Composio over Pipedream because it delivered depth where it mattered — niche tools and tricky edge cases other platforms simply ignored. That gave us confidence to scale without compromising.

As a solo builder, shipping fast is life or death. The only way I can outcompete incumbents is by outmanoeuvring them. Getting bogged down managing agent auth would have been a death sentence.

Before Composio, adding tool integrations was slow and resource-intensive. Each one could take weeks of engineering time, and maintaining them meant constantly keeping up with API changes.
