This is an open-source browser extension and Electron browser project, not a project with a clearly documented MCP server interface. The README supports browser automation, sidebar chat, and Composio integration features, but provides no server manifest, MCP tool identifiers, transport details, client compatibility, or license information.
Open ChatGPT Atlas is a browser automation project built as a Chrome or Edge extension, with a standalone Electron browser application. It provides Browser Tools mode, Tool Router mode, and a sidebar chat interface. Browser Tools mode uses Gemini 2.5 Computer Use for screenshots, clicks, typing, scrolling, and navigation; Tool Router mode can access integrations such as Gmail, Slack, and GitHub through Composio.
Tools
The tool list has not been reviewed yet.
Setup
Requires Node.js 18+, npm, Chrome or Edge with Manifest V3 support, and a required Google API key. Run npm install and npm run build, then enable Developer mode at chrome://extensions/ and load the dist folder. To run the Electron browser, run npm run build:electron followed by npm run electron; development mode is available with npm run electron:dev. A Composio API key is only required for Tool Router mode.
Fit and risk
Not for
- Users seeking a documented MCP server transport or standard client configuration.
- Users unwilling to provide a Google API key.
- Production environments requiring confirmed official maintenance or a known license.
Required permissions
- Requires browser-extension access to perform screenshots, clicks, typing, scrolling, and navigation on web pages.
- Requires a Google API key; Tool Router mode additionally requires an optional Composio API key.
- May access user-controlled web content and data from configured integrations.
Risks and side effects
- Browser automation may perform sensitive actions; the project provides confirmation dialogs for actions such as checkout and payment.
- The handling risk for API keys, web content, and integration data depends on configuration and usage.
- The license is listed as unknown, so specific commercial or redistribution rights should not be assumed.
Troubleshooting
- Confirm that Node.js 18+ and npm are installed and that npm install completed successfully.
- Confirm that npm run build completed and that the dist folder was loaded in Chrome or Edge.
- Confirm that Developer mode is enabled for Manifest V3 extension loading.
- Confirm that the required Google API key is configured; when using Tool Router mode, check the Composio API key.
- After code changes, rebuild and reload the extension in the browser.
Use cases
Control browser navigation, clicks, typing, scrolling, and screenshots with natural-language instructions.
