Vessel Browser running

Install in your client

Paste into the AI you're chatting with — it will figure out the rest

Please install the `vessel-browser` MCP server into my current AI client (that's you).

Required prerequisites (do these first if not already done):
- **Node.js** — Required to run via npm/npx (https://nodejs.org/)
- **Vessel Browser running** — Vessel must already be running when your MCP client connects Run: `npx @quanta-intellect/vessel-browser`

Canonical MCP server config (stdio transport):
- command: `npx`
- args: ["-y","@quanta-intellect/vessel-browser","--stdio"]

Note: Vessel is a Chromium-based browser for persistent web agents. The recommended stdio config uses the vessel-browser-mcp helper with --stdio flag which reads bearer token from ~/.config/vessel/mcp-auth.json automatically. HTTP transport is also available at http://127.0.0.1:3100/mcp with bearer token.

Add this MCP server to my current client's config in the correct format for you. If you need secrets or credentials I haven't provided, ASK me — do not invent values or leave raw placeholders. After adding it, tell me how to verify the server is connected.
