agnt
Give your AI coding agent browser superpowers.
agnt is a new kind of tool designed for the age of AI-assisted development. It acts as a bridge between your AI coding agent and the browser, extending what's possible during vibe coding sessions.
What Does It Do?
When you're in the flow with Claude Code, Cursor, or other AI tools, agnt lets your agent:
- See what you see - Screenshots, DOM inspection, visual debugging
- Hear from you directly - Send messages from browser to agent
- Sketch ideas together - Draw wireframes directly on your UI
- Debug in real-time - Capture errors, network traffic, performance
- Extend its thinking window - Structured data uses fewer tokens than descriptions
Installation
pip install agnt
# or
uv pip install agnt
# or
pipx install agnt
Quick Start
As MCP Server (Claude Code, Cursor, etc.)
Add to your MCP configuration:
{
"mcpServers": {
"agnt": {
"command": "agnt",
"args": ["mcp"]
}
}
}
Or with uvx:
{
"mcpServers": {
"agnt": {
"command": "uvx",
"args": ["agnt", "mcp"]
}
}
}
As PTY Wrapper
Wrap your AI coding tool with overlay features:
agnt run claude --dangerously-skip-permissions
agnt run cursor
agnt run aider
This adds a terminal overlay menu (Ctrl+P) and enables browser-to-terminal messaging.
Core Features
Browser Superpowers
Start a proxy and your agent gains eyes into the browser:
proxy {action: "start", id: "app", target_url: "http://localhost:3000"}
Now your agent can:
- Take screenshots
- Inspect any element
- Audit accessibility
- See what you clicked
Floating Indicator
Every proxied page gets a floating bug icon. Click to:
- Send messages to your agent
- Take area screenshots
- Select elements to log
- Open sketch mode
Sketch Mode
Draw directly on your UI:
- Shapes: rectangles, circles, arrows, freehand
- Wireframes: buttons, inputs, sticky notes
- Save and send to agent instantly
Real-Time Error Capture
JavaScript errors automatically captured and available to your agent - no more forgetting to mention them.
