About
T3rnel Browser is built by T3raTech Solutions (Pvt) Ltd. It is a browser extension with 97 tools and no servers behind it: what it does, it does on your machine.
What we make
| Product | What it is | Where to get it |

| T3rnel Document Intelligence | A Cloudflare Worker for evidence-backed invoice and receipt extraction into validated accounting data. Five Streamable HTTP MCP tools and a dashboard. | Live app |
| Agent skills | Free, open instructions that teach an agent when to use these tools and — as importantly — when not to. | Agent skills |
Install the extension
Pick your browser. Installing is free and takes one click; the Pro tier is a one-time purchase you can make later from inside the extension.
Support varies by browser — the overview says exactly where and why.
Add it to your AI client
The bridge is free and needs no licence — npx -y @t3ratech/mcp-session-bridge is the whole command:
{
"mcpServers": {
"t3rnel-session": {
"command": "npx",
"args": ["-y", "@t3ratech/mcp-session-bridge"]
}
}
}The extension finds it over a local WebSocket — no install step, no native host. The MCP tools page lists everything it exposes, and the bridge's own session_install tool repeats these steps to your assistant at any time.

How we work
- Nothing leaves your device by default. No account, no analytics, no telemetry, no error reporting — an anonymous usage counter exists but is off until you switch it on. The privacy policy lists every case where the extension makes a network request at all.
- Pro is verified offline. Your licence is checked once at activation and on your own device after that.
- No evasion, ever. There is no fingerprint spoofing, user-agent rotation or anti-bot circumvention in this product, and there will not be.
- We say where it is weak. Partial browser support and the limits of every safety feature are written down rather than left to be discovered.
