v0.1.0 MIT Chromium 116+

The manual, in six pages.

HailBrowser is a Chrome extension, a side panel agent, and a local MCP server. These pages cover all three without assuming you have read the source. Start with install if you want it running in two minutes; start with the MCP reference if you only care about what your agent can call.

Start

Install

Clone, load the folder, add a key, verify it works.

MCP reference

All twenty tools, parameters, return shapes and failures.

Behaviour

Modes

Chat, Fast, Research and Tasks: what each one does and costs.

Behaviour

Security

Keys, loopback, the trust file and what agents will not do.

Behaviour

Limits

What version 0.1.0 cannot do yet, without hedging.

The sixty-second version

Clone it, load it, key it, connect it.

The extension has no build step and no npm dependencies. The MCP server is a Node process your client starts; the extension dials into it. Nothing is installed system-wide.

Reading this on a phone?

The install itself needs a desktop Chromium browser. The docs, the tool reference and the use cases read fine anywhere.
