Vessel Browser

Vessel Browser is an open source, MCP-compatible server that exposes a persistent, AI-native browser runtime purpose-built for autonomous agents with human-in-the-loop supervision. It enables AI agents (such as those using Claude, Cursor, Hermes Agent, or OpenClaw) to interact with a real browser that maintains state (sessions, bookmarks, transcripts), supports supervised automation, and offers specialized agent tools like workflow tracking, credential storage, page highlighting, and visual analysis. Vessel integrates with various LLM providers (Anthropic, OpenAI, Mistral, xAI and more) and structured agent frameworks, making it valuable for autonomous browsing, multi-turn workflows, OSINT gathering, and agent-driven research or automation where ongoing human oversight is critical.
