Connect AI agents to the Anchor Browser MCP server

Vendor MCP

The Anchor Browser MCP connector routes your AI agent's tool calls to Anchor Browser's own MCP server through Scalekit. Each user signs in to Anchor Browser once, and Scalekit stores and refreshes their tokens, so your agent never handles credentials. It comes with 25 tools.

Setup

Install the SDK
- Node.js
- Python
Terminal window
npm install @scalekit-sdk/node dotenv
Terminal window
pip install scalekit-sdk-python python-dotenv
Set your credentials
Add your Scalekit credentials to your .env file. Find values in app.scalekit.com > Developers > API Credentials.
.env
```
SCALEKIT_ENVIRONMENT_URL=<your-environment-url>
SCALEKIT_CLIENT_ID=<your-client-id>
SCALEKIT_CLIENT_SECRET=<your-client-secret>
```
Create the Anchor Browser MCP connection
In AgentKit > Connections, create an Anchor Browser MCP connection. The name you give it is the connection_name your code passes. See Configure connections.
Scalekit credentials are available for Anchor Browser MCP server, so you don't need to register an OAuth app.
