Auto Browser

Give your AI agent a real browser, with a human in the loop.

Auto Browser is an MCP-native browser control plane for authorized workflows. It gives MCP clients, LLM agents, and operators a shared Playwright browser with human takeover, reusable auth profiles, approvals, audit trails, and local-first deployment.

Works with:

• Claude Code, Codex (CLI, IDE extension, and app), Google Antigravity, Cursor, and VS Code, connected directly over HTTP
• Claude Desktop, through the bundled stdio bridge
• any MCP client that can talk HTTP or stdio
• direct REST callers when you want curl-first control

Why Auto Browser

• MCP-native from day one. The browser surface is already packaged as an MCP server instead of bolted on after the fact.
• Human takeover when the web gets brittle. noVNC keeps the same live session available when a person needs to step in.
• Login once, reuse later. Save named auth profiles and reopen fresh sessions that are already signed in.
• Local-first by default. Run the full stack on your own box with Docker Compose, or use Codespaces for a quick hosted demo.
• Safety rails built in. Approvals, operator identity, PII scrubbing, Witness receipts, and policy presets are all part of the product surface.
• Evidence you can hand to someone else. Witness receipt chains are Ed25519-signed, and an exported bundle verifies with scripts/verify_witness_bundle.py — which imports nothing from this project, so a recipient need not run or trust this controller to check it.
• We audit ourselves in public. docs/audits/2026-08-execution-audit.md documents an adversarial audit of this repo that found safety controls which reported success while doing nothing, with reproductions, the fixes, and the gates that close the class.
• Governed skill induction. Verified browser traces can become staged skill candidates with provenance that is signed when a mesh identity is configured — and checked on read, not just produced — plus verifier adapters and review-only graduation — agents that prove they can repeat themselves correctly, not just act once.

Good Fits

• internal dashboards and admin tools
• operator-assisted QA and browser debugging
• login-once, reuse-later account workflows
• brittle sites where a human may need to recover the flow
• MCP-powered agent workflows that need a real browser, not just HTML fetches

Not the Goal

• CAPTCHA solving
• unauthorized scraping or account automation
• deceptive identity shaping or bypass tooling

What You Get

Browser Control	Operator Safety	Deployment and Integration
Playwright-backed sessions with screenshots, DOM summaries, OCR excerpts, tab controls, downloads, and network inspection	approval gates, operator identity headers, audit events, PII scrubbing, Witness receipts, and protection profiles	MCP over HTTP, bundled stdio bridge, REST API, Docker Compose, Codespaces, auth profiles, and optional per-session isolation

Quickstart

git clone https://github.com/LvcidPsyche/auto-browser.git
cd auto-browser
docker compose up --build

That is enough for local development with the default settings.

Optional:

cp .env.example .env
make doctor

Run make doctor from a normal terminal with local Docker access and permission to open localhost sockets.
