## Introduction

### How to connect Google Stitch MCP with ChatGPT
[ChatGPT](https://chatgpt.com/) can take action across your apps and files, stay with a project for hours, and turn a goal into finished materials like sheets, slides, and docs, not just answers.
In this guide, I will explain the easiest and most secure way to connect your Google Stitch account to ChatGPT via Composio Connect, so it can manage projects, create screens, inspect artifacts, update design systems, and organize designs through natural language commands without ever putting your account credentials at risk.

## Also integrate Google Stitch with

- [Hermes](https://composio.dev/toolkits/google_stitch/framework/hermes-agent)
- [Atomic Agent](https://composio.dev/toolkits/google_stitch/framework/atomic-agent)

## TL;DR

### Why use Composio over default connectors?
- Apps with read and write access. Default connectors mostly can read your data. Composio's Google Stitch integration lets ChatGPT take actions like creating drafts, sending updates, labeling records, and more.
- 1,500+ SaaS toolkits out of the box. Composio gives you instant access to a vast catalog of pre-built connectors, from Gmail and Slack to Notion, Linear, and Salesforce.
- 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.
- Cross-app automation. Chain actions across multiple apps in a single run - fetch a thread, summarize it in Notion, and post highlights to Slack without leaving the conversation.

## Connect Google Stitch to ChatGPT

### Prerequisites
- A ChatGPT account. We will use the [ChatGPT desktop app](https://openai.com/chatgpt/download/), and the steps are the same on the web.
- Access to the Google Stitch workspace you want to connect.
- [Composio plugin](https://dashboard.composio.dev/login?utm_source=toolkits&utm_medium=framework_template&utm_campaign=chatgpt&utm_content=composio_connect&next=%2F~%2Forg%2Fconnect%2Fclients%2Fchatgpt).
Note: Composio connects through OAuth. You will be asked to sign in and approve specific permissions. Review the permission screen carefully if you are using a work account.
### Step-by-step: Connect Google Stitch to ChatGPT
### 1. Install the Composio plugin
Click the button. ChatGPT opens the Composio plugin page. Click Install plugin.
[Install in ChatGPT](https://chatgpt.com/plugins/plugin_asdk_app_6a58503580c08191b78cc5bdaf4eba6e)
You can also find it inside ChatGPT: go to Settings, open Plugins, search the marketplace for Composio, and click Install plugin.
### 2. Authenticate
After you install, ChatGPT asks you to authenticate with Composio. Log in and click Allow access to authorize ChatGPT to use your Composio account.
### 3. Start using Composio
That is it. Composio tools are now available in ChatGPT. Type @Composio followed by your request, for example @Composio find unread Google Stitch messages and summarize them, and it will run the actions you authorize. On first use it asks you to authorize Google Stitch.
### Option 2: Add Composio as an MCP server
If you cannot use the plugin marketplace, add Composio as a custom MCP server instead.
### 1. Open the MCP settings
In ChatGPT, go to Settings and open the Plugins section. Inside the Plugins page, click the MCP tab.
### 2. Add the server
Click Add server. In the Name field enter Composio, for Type select Streamable HTTP, and in the URL field paste the Composio MCP server URL:

```bash
https://connect.composio.dev/mcp
```

## What is the Google Stitch MCP server, and what's possible with it?

The Google Stitch MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Google Stitch account. It provides structured and secure access to your projects, screens, design systems, and design files, so your agent can create interface designs, edit screens, generate variants, apply design systems, and manage project assets on your behalf.
- Project creation and management: Have your agent create, list, inspect, and permanently delete Google Stitch projects.
- AI screen generation and editing: Direct your agent to generate screens from text prompts, edit existing screens with text instructions, and retrieve screen details.
- Design exploration with variants: Let the agent create multiple screen variants with specified creative ranges, aspect ratios, device types, and supported models.
- Design system workflows: Instruct your agent to create, update, list, and apply design systems across screens, or build a design system from uploaded DESIGN.md content.
- Screen file access: Have your agent list screens and download available HTML or screenshot files for use in your design workflow.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `GOOGLE_STITCH_APPLY_DESIGN_SYSTEM` | Apply Design System | Apply one design system to 1-20 unique typed screen instances from Get Project. Returns every restyled screen plus any clarification, progress, design-system, or session output. This mutating generation request is sent once and never retried; reconcile an indeterminate failure with project reads. |
| `GOOGLE_STITCH_CREATE_DESIGN_SYSTEM` | Create Design System | Create a typed Stitch design system from explicit current theme fields. Providing project_id creates it for that project; intentionally omitting project_id creates a global asset. This non-idempotent operation is attempted once and is never retried automatically. |
| `GOOGLE_STITCH_CREATE_DESIGN_SYSTEM_FROM_DESIGN_MD` | Create Design System From Markdown | Create a project design system from the exact screen instance returned by Upload Design Markdown. The non-idempotent request is sent once and is never retried by this action. |
| `GOOGLE_STITCH_CREATE_PROJECT` | Create Project | Create a Stitch project container for UI designs and return its project resource name. This non-idempotent operation is sent once and is not retried by the action. |
| `GOOGLE_STITCH_DELETE_PROJECT` | Delete Project | Permanently delete one Google Stitch project. This destructive operation cannot be undone, requires explicit confirmation, and is attempted once without automatic retries. |
| `GOOGLE_STITCH_DOWNLOAD_FILE` | Download Screen File | Retrieve bounded HTML or screenshot content using a provider-owned Stitch file resource name. Arbitrary URLs are never accepted or fetched. |
| `GOOGLE_STITCH_EDIT_SCREENS` | Edit Screens | Apply one text-directed edit to up to 20 existing Stitch screens and return every changed screen or clarification question. This operation may continue after a timeout, so the action sends exactly one request and never retries. |
| `GOOGLE_STITCH_GENERATE_SCREEN` | Generate Screen | Generate screens from a bounded text prompt in an existing Stitch project. Returns every generated screen or recoverable clarification output. This paid or mutating operation is attempted exactly once; a timeout or connection loss is indeterminate and is never retried automatically. |
| `GOOGLE_STITCH_GENERATE_VARIANTS` | Generate Screen Variants | Generate 1-5 variants for up to 20 unique source screens with exact creative-range, aspect, device, and model enums. Returns every generated screen or recoverable clarification output. This generation request is sent once and never retried. |
| `GOOGLE_STITCH_GET_PROJECT` | Get Project | Get one Stitch project by full resource name, including screen instances needed for design-system application. |
| `GOOGLE_STITCH_GET_SCREEN` | Get Screen | Get one Stitch screen by full resource name and return bounded screen metadata plus provider-owned HTML and screenshot file references. |
| `GOOGLE_STITCH_LIST_DESIGN_SYSTEMS` | List Design Systems | List complete Google Stitch design systems for one project. The live provider requires project_id and exposes no pagination. |
| `GOOGLE_STITCH_LIST_PROJECTS` | List Projects | List complete Google Stitch projects owned by the connected account or explicitly shared with it. Owned projects are returned by default. |
| `GOOGLE_STITCH_LIST_SCREENS` | List Screens | List all screens currently returned for one Stitch project, including safe HTML and screenshot file resource references. |
| `GOOGLE_STITCH_UPDATE_DESIGN_SYSTEM` | Update Design System | Replace a Stitch design system's display name and typed nondeprecated theme for one project. Sends only the fixed update_design_system operation, validates the returned asset or project-session identity and bounded fields, and never retries an indeterminate update. |
| `GOOGLE_STITCH_UPLOAD_DESIGN_MD` | Upload Design Markdown | Upload bounded UTF-8 DESIGN.md content to a Stitch project and return the screen instance required by Create Design System From Markdown. The action uploads content only, never reads local files or executes the content, and does not retry after an indeterminate failure. |

## Frequently Asked Questions

### What are the differences in Tool Router MCP and Google Stitch MCP?

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

### Can I use Tool Router MCP with ChatGPT?

Yes, you can. ChatGPT 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 Google Stitch tools.

### Can I manage the permissions and scopes for Google Stitch while using Tool Router?

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