MCP Session Bridge runs on your own machine — the client starts it, so there is no endpoint to ping. 32 installs a week from npm. Last commit 28 Sep 2026.

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.
We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

Optional settings from the registry entry, left out of the block above:
T3RNEL_SESSION_MODE (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 (Set to 1 to run the standalone browser headless. Ignored in extension mode), T3RNEL_SESSION_TIMEOUT_MS (How long a single tool call may take before it fails rather than hanging the client).
