在上方选择你的应用。我们会记住它，下次按钮会显示“安装到 …”。

打开 Claude Desktop → Settings → Developer → Edit Config，把下面的内容粘贴到 claude_desktop_config.json

{
  "mcpServers": {
    "session-bridge": {
      "command": "npx",
      "args": [

在终端中运行这条命令

claude mcp add session-bridge --env T3RNEL_SESSION_MODE=your-value --env T3RNEL_SESSION_HEADLESS=your-value --env T3RNEL_SESSION_TIMEOUT_MS=your-value -- npx -y @t3ratech/mcp-session-bridge

运行前请先填写空着的值。

在 Cursor 中打开

或者自己复制设置

粘贴到项目中的 .cursor/mcp.json，或 ~/.cursor/mcp.json

  }
}

浏览器会先询问是否打开应用，然后应用会显示设置并请你确认。密钥的值会留空，由你自己填写。

在 VS Code 中打开

或者自己复制设置

需要你填写的值

T3RNEL_SESSION_MODE env
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 env
Set to 1 to run the standalone browser headless. Ignored in extension mode.
T3RNEL_SESSION_TIMEOUT_MS env
How long a single tool call may take before it fails rather than hanging the client.

MCP Session Bridge

A free MCP (Model Context Protocol) server that exposes authenticated browser-session automation: session_* tools that run in the user's own Chrome profile and real logged-in session, which cloud browser APIs cannot do. A free standalone mode is also available; it launches a dedicated automation browser so the same session_* tools work without the extension or a license.

What it does

Serves MCP over stdio (newline-delimited JSON-RPC) to any client that speaks the Model Context Protocol. The setup guide covers the common ones.
Uses a dual-transport design:
Extension mode (free; Pro tools gated by the extension) — forwards calls over a local, owner-only relay socket to a native messaging host that Chrome spawns, and from there to the T3rnel Browser extension, which executes them against the live authenticated tabs.
Standalone mode (free) — launches its own headful or headless CDP browser on a persistent profile and drives it directly. No license, no extension, and no access to the user's everyday browser.
Returns structured page context, form values, snapshots, and screenshots without shipping session cookies to a remote browser.

Price

The bridge itself is free, and this package enforces no licence of its own.

Extension mode reaches the buyer's real authenticated session through the T3rnel Browser extension, and the Pro tools it exposes are gated by that extension's own Pro tier — $29.99 once, three devices. Standalone mode is free and needs neither the extension nor a licence. There is no separate subscription for this package, and nothing here checks for one; earlier drafts of this file advertised $9/mo and $39/mo tiers that were never implemented, never enforced and never purchasable.

Project layout

src/server.js — MCP stdio server: tool surface, schema validation, dual-transport routing, relay client with reconnect and timeouts, and standalone CDP launcher.
src/cdp.js — standalone CDP browser management and WebSocket client.
src/native-host.js — native messaging host spawned by Chrome; owns the relay socket and multiplexes concurrent MCP servers.
src/framing.js — the 4-byte length-prefixed JSON framing shared by native messaging and the relay socket.
src/tools.js — the session_* tool definitions, validation, and mapping to the extension's browser_* tools.
src/license.js — offline Ed25519 license verification helpers used by the extension and tests.
src/install.js — --install / --uninstall native host registration for Chrome, Chromium, Brave and Edge.
docs/setup-guide.md — installing on the common MCP clients, plus verification and troubleshooting.
docs/chrome-validation-checklist.md — end-to-end validation steps for Chrome with the T3rnel Browser extension.
ads/ — ad-copy.md, the shared headline and description copy used when submitting to MCPize, Smithery, mcp.so and PulseMCP.
tests/ — node --test suite, including end-to-end tests through a real relay socket and native-messaging framing, plus standalone-mode coverage.

Browser support

Extension mode needs the T3rnel Browser extension, which is packaged for Chrome, Brave, Edge, Opera, Chromium and Firefox and ships from each browser's own extension store. Brave and Chromium install from the Chrome Web Store; Edge, Opera and Firefox each have a separate package. Opera implements no side-panel API and Firefox no debugger API, so both are partly supported; the extension's manifest generator states which capabilities are absent on each. Standalone mode has no browser requirement at all — it launches its own CDP browser.

The extension exposes up to 100 browser tools, plus the bridge's own session_install setup tool. If the merged list would exceed 100 tools — which Google Antigravity refuses to install — the bridge drops the two lowest-value verbs (session_md_diff, session_check_spelling) so the published list stays at or under the ceiling for every extension build. Dropped tools still execute when called by name; all tools remain subject to the extension's Pro gating and approval gate.
