Why use Composio?

Composio provides:

  • Access to 1,000+ managed apps from a single MCP endpoint. This makes it convenient for agents to run cross-app workflows.
  • Programmatic tool calling. Allows LLMs to write code in a remote workbench to handle complex tool chaining. Reduces to-and-fro with LLMs for frequent tool calling.
  • Large tool response handling outside the LLM context. This minimizes context bloat from large tool responses.
  • Dynamic just-in-time access to thousands of tools across hundreds of apps. Composio loads the tools your agent needs, so LLMs are not overwhelmed by tools they do not need.

Connect Nango to Antigravity

Antigravity does not ship with one-click custom MCP install links yet, so configuration goes through the IDE's raw config file. The process takes under a minute.

1. Open the MCP Config

Go to Antigravity Settings, open the Customizations tab, then click Open MCP Config to open mcp_config.json in the editor.

2. Get your API key

Go to the Composio Dashboard and copy your API key.

3. Add Composio to mcp_config.json

Paste the following configuration into the file:

bash
{
  "mcpServers": {
    "remote-composio": {
      "serverUrl": "https://connect.composio.dev/mcp",
      "headers": {
        "x-consumer-api-key": "your-composio-api-key"
      }
    }
  }
}

Note: Antigravity uses serverUrl, not url, for remote HTTP-based MCP servers. This differs from the url key used in Cursor and VS Code configs.

Save the file and click refresh in the Installed MCP Servers section.

Connect your Nango account

Back in the Antigravity agent panel, ask the agent to connect to Nango or give it any Nango-related task.

For example, ask it to:

  • "List all connected CRM accounts"
  • "Trigger manual sync with Salesforce provider"
  • "Get configuration for all available scripts"

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

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

Conclusion

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

FAQ

Frequently asked questions

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

Yes, you can. Antigravity 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 Nango tools.

Yes, absolutely. You can configure which Nango 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 Nango 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.
