How to integrate Capsule crm MCP with Antigravity

Antigravity IDE is Google's agentic IDE, built on a VS Code-style editor and powered by models like Gemini 3.5 Flash, Gemini 3.1 Pro, Opus 4.6, and more. It treats the AI agent as a first-class teammate, planning, coding, and validating work through an Agent Manager dashboard with deep browser connectivity.

In this guide, I will explain the easiest and most secure way to connect your Capsule crm account to Antigravity IDE via Composio Connect, so it can add new company and contact details, list all open tasks for today, show all projects started this month, and more without ever putting your account credentials at risk.

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 Capsule crm 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 Capsule crm account

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

For example, ask it to:

  • "Add new company and contact details"
  • "List all open tasks for today"
  • "Show all projects started this month"

It will prompt you to authenticate and authorize access to Capsule crm.

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

How to build Capsule crm MCP Agent with another framework

FAQ

What are the differences in Tool Router MCP and Capsule crm MCP?

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

Can I use Tool Router MCP with Antigravity?

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 Capsule crm tools.

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

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