About mcp-session-bridge
mcp-session-bridge is an MCP server published by the GitHub account t3ratech. Drive a browser you are already signed into, through the free T3rnel Browser extension.
It runs on your own machine: your AI client starts it from the npm package @t3ratech/mcp-session-bridge at version 1.2.0.
It asks for no keys or passwords.
Version 1.2.0 was published on 5 September 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 9 automated checks on the registry entry and the package code: 7 pass, 0 warn, 0 fail, 2 info. How we check.
What it asks for
| Variable | Required | Secret | Description |
|---|---|---|---|
T3RNEL_SESSION_MODE | No | No | auto (default) uses the extension when its relay socket exists and falls back to a standalone browser; extension forces the extension; standalone forces its own browser. |
T3RNEL_SESSION_HEADLESS | No | No | Set to 1 to run the standalone browser headless. Ignored in extension mode. |
T3RNEL_SESSION_TIMEOUT_MS | No | No | How long a single tool call may take before it fails rather than hanging the client. |
