How to connect Gemini MCP with VS Code

VS Code is the most popular code editor out there. With its recent AI makeover, it can do more than just help you write code. You can connect your applications to it and let LLMs automate many of the mundane tasks in your workflow.

In this guide, I will explain how to connect Gemini with VS Code in the most secure and robust way possible via Composio.

Also integrate Gemini with

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 its 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.

Integrate Gemini MCP with VS Code

1. Install with one click

Click the button below to add Composio to VS Code. You will be prompted to authorize. This requires VS Code 1.99+ with GitHub Copilot.

+Install in VS Code

2. Or add manually

Open or create .vscode/mcp.json in your project root and add the following configuration:

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

3. Authorize

Click the install button to authorize VS Code to connect to Composio. VS Code will detect OAuth and prompt you to sign in.

A browser window will open to authorize.

4. Authenticate Gemini and start working

Back in VS Code chat, ask the agent to connect to Gemini or give it any Gemini-related task.

For example, ask it to:

  • "Summarize this research article in 100 words"
  • "Generate a creative image of a futuristic city"
  • "Create a 30-second video based on this script"

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

That is it. Composio tools are now available in VS Code, and your Gemini account is ready to use.

Supported Tools & Triggers

Tools
Count Tokens (Gemini)Counts the number of tokens in text using gemini tokenization.
Download Video (Veo)Downloads a generated veo video to local storage.
Embed Content (Gemini)Generates text embeddings using gemini embedding models.
Generate Content (Gemini)Generates text content from prompts using gemini models.
Generate Image (Gemini 2.5 Flash)Generates images from text prompts using gemini 2.
Generate Videos (Veo)Generates videos from text prompts using google's veo models.
Get Videos Operation (Veo)Checks the status of a veo video generation operation.
List Models (Gemini API)Lists available gemini and veo models with their capabilities and limits.
Wait For Video (Veo)Polls a veo video generation operation until completion or timeout.

Way Forward

Now that Gemini is connected, extend your setup by connecting the other apps you already use every day, so your agent can run true cross-app workflows end to end.

  • Connect Calendar to turn threads into scheduled meetings automatically.
  • Connect Slack or Teams to post summaries, approvals, and alerts where your team works.
  • Connect Notion, Linear, Jira, or Asana to convert requests into tickets, tasks, and docs.
  • Connect Drive, Dropbox, or OneDrive to fetch, file, and share attachments without manual steps.
  • Connect HubSpot or Salesforce to log customer context, update records, and draft follow-ups.

Start with one workflow you do repeatedly, then keep adding apps as you find new handoffs. With everything behind a single MCP endpoint, your agent can coordinate multiple tools safely and reliably in one conversation.

FAQ

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

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

Can I use Tool Router MCP with VS Code?

Yes, you can. VS Code 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 Gemini tools.

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

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