An open-source AI browser for autonomous agents with durable state, MCP control, and human supervision.
vessel-browser is worth checking the docs before setup with trust notes worth reviewing. Check agent compatibility and use-case fit before adding it to your workflow.

Bidirectional MCP bridge that lets AI draw UI directly on Figma canvas and read designs back as structured data.
Vessel Browser is a web browser built for AI agents, not humans. It keeps browser sessions alive, allows agents to control it via MCP, and lets humans watch and intervene when needed. It works with agent frameworks like Hermes Agent and OpenClaw.
Vessel Browser is an open-source, Chromium-based browser designed from the ground up for autonomous AI agents. Unlike traditional browser automation tools that are headless or stateless, Vessel provides a persistent, stateful browser environment that agents can control via the Model Context Protocol (MCP). It features named sessions, pinned tabs, editable bookmarks, annotated checkpoints, action undo, and a visible supervisory UI for humans. Built for long-running agent workflows, Vessel keeps humans in the loop with approval requests, runtime controls, and full visibility into agent actions. It supports Linux, macOS, and Windows, and can be installed via AppImage, npm, or built from source. Vessel is compatible with agent harnesses such as Hermes Agent, OpenClaw, and any MCP client. The project is in active development and currently makes no security assurances.
An open-source AI browser for autonomous agents with durable state, MCP control, and human supervision.
AI/ML engineers building autonomous agent systems that need a durable browser environment., Developers creating MCP servers or clients that require a full-featured browser for agent interactions., Researchers and QA engineers who need to observe and supervise agent-driven web automation.
The setup section provides repository-level starting guidance, not a guarantee of an independently verified installation. Check the official README and release notes.
No security assurances are provided; use with caution in production environments. The browser runs with full system access; agents could potentially execute harmful actions if not properly supervised.
