Your AI agent is burning 6x more tokens than it needs to just to browse the web.
We built OpenBrowser MCP to fix that.
Most browser MCPs give the LLM dozens of tools: click, scroll, type, extract, navigate. Each call dumps the entire page accessibility tree into the context window. One Wikipedia page? 124K+ tokens. Every. Single. Call.
OpenBrowser works differently. It exposes one tool. Your agent writes Python code, and OpenBrowser executes it in a persistent runtime with full browser access. The agent controls what comes back. No bloated page dumps. No wasted tokens. Just the data your agent actually asked for.
The result? We benchmarked it against Playwright MCP (Microsoft) and Chrome DevTools MCP (Google) across 6 real-world tasks:
- 3.2x fewer tokens than Playwright MCP
- 6x fewer tokens than Chrome DevTools MCP
- 144x smaller response payloads
- 100% task success rate across all benchmarks
One tool. Full browser control. A fraction of the cost.
It works with any MCP-compatible client:
- Cursor
- VS Code
- Claude Code (marketplace plugin with MCP + Skills)
- Codex and OpenCode (community plugins)
- n8n, Cline, Roo Code, and more

It connects to any LLM provider: Claude, GPT 5.2, Gemini, DeepSeek, Groq, Ollama, and more. Fully open source under MIT license.
OpenBrowser MCP is the foundation for something bigger. We are building a cloud-hosted, general-purpose agentic platform where any AI agent can browse, interact with, and extract data from the web without managing infrastructure. The full platform is coming soon.
