- Control browser automation agents via the Bits MCP server. Use when running web scraping, form filling, data extraction, or any browser-based automation task. Bits agents can navigate websites, click elements, fill forms, handle OAuth flows, and extract structured data.
Bits MCP - Browser Automation
Bits is an AI browser automation platform. The MCP server lets you run browser automation tasks from your AI assistant.
Setup
1. Get an API Key
- Go to app.usebits.com
- Sign in with Google
- Navigate to Settings → API Keys
- Click Create API Key, give it a name
- Copy the key (starts with
bb_) — you won't see it again
2. Configure MCP
Add to your MCP config (e.g., ~/.openclaw/openclaw.json):
{
"mcpServers": {
"bits": {
"command": "npx",
"args": ["-y", "usebits-mcp"],
"env": {
"BITS_API_KEY": "bb_your_key_here"
}
}
}
}For Claude Code (~/.claude.json):
{
"mcpServers": {
"bits": {
"command": "npx",
"args": ["-y", "usebits-mcp"],
"env": {
"BITS_API_KEY": "bb_your_key_here"
}
}
}
}3. Restart
Restart your gateway/client to pick up the new MCP server.
Usage
The Bits MCP uses "Code Mode" — you write TypeScript SDK code that executes in a sandbox. Two tools are available:
- Documentation search — Query the SDK docs
- Code execution — Write and run TypeScript against the Bits SDK
Example: Scrape a Website
Use the Bits MCP to go to news.ycombinator.com and get the top 5 story titlesThe agent will:
- Search docs for navigation/scraping methods
- Write TypeScript code to navigate and extract data
- Execute it and return results
Example: Fill a Form
Use Bits to go to example.com/contact, fill out the contact form with name "Test" and email "test@example.com", then submitExample: Extract Structured Data
Use Bits to scrape the product listings from example-store.com/products and return them as JSON with name, price, and URL fieldsCapabilities
- Navigate — Go to URLs, handle redirects
- Read pages — Extract text, get page layouts, take screenshots
- Interact — Click elements, fill inputs, press keys
- Handle auth — OAuth popups, login forms, 2FA (with stored credentials)
- Multi-window — Switch between tabs/popups
- Structured output — Return data in specific JSON schemas
Creating Workflows (Optional)
For repeated tasks, create a workflow in the Bits web app:
- Go to app.usebits.com → Workflows
- Create a workflow with a definition (instructions for the agent)
- Optionally add an output schema for structured responses
- Run via API:
POST /workflows/{id}/runs
Troubleshooting
"API key invalid" — Check your key starts with bb_ and is copied correctly.
Slow startup — First run downloads the MCP package via npx. Subsequent runs are faster.
Task stuck — Browser automation can hit CAPTCHAs or unexpected modals. Check the live view URL in the response.
