A command for managing a locally running Claude Code Chrome Bridge, which connects Claude Code to a Chrome browser. It checks installation, status, logs, and service restarts on the current computer.

Use it to install, start, restart, inspect, or check the health of the local Chrome Bridge service.

It gives each computer its own bridge, token, and background service instead of relying on a shared server. It also reports whether the bridge and browser extension are connected.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00024	$0.02064
Opus 5	$0.00012	$0.01032
Sonnet 5	$0.00005	$0.00413
Haiku 4.5	$0.00002	$0.00206

Security

Grade C, and why

ccchrome scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Bạn đang quản lý Claude Code Chrome Bridge chạy như một dịch vụ nền trên chính máy này (cài bằng scripts/install.sh, xem README mục Cài đặt). Không còn server dùng chung/VPS, không còn pairing secret — mỗi máy tự chạy bridge riêng, mỗi bridge một token riêng.

File trạng thái: ~/.ccchrome.json — nội dung {"token": "...", "port": 23949}, do install.sh tạo. Thư mục cài đặt: ~/.cc-chrome-bridge/ (mã nguồn, logs/, service-unit.sh, tokens.json).

Subcommand người dùng gõ: $ARGUMENTS (không có thì coi là status).

`status`

Mục tiêu: báo bridge có đang chạy không và extension đã nối vào chưa.

Đọc ~/.ccchrome.json bằng cat. Không có file này → báo "chưa cài — chạy /ccchrome install" rồi dừng lại, không làm các bước dưới.
Lấy port từ file đó (mặc định 23949 nếu thiếu trường này). Gọi:
```
curl -sS --max-time 5 http://127.0.0.1:<port>/health
```
- Không có phản hồi / connection refused → bridge không chạy. Báo vậy và gợi ý /ccchrome restart (dịch vụ nền có thể đã bị dừng hoặc crash).
- Có phản hồi JSON {"ok":true,"version":"...","extensionsConnected":N,"mcpSessions":M} → bridge đang sống. Đọc extensionsConnected:
  - 0 → extension chưa nối. Nhắc người dùng: bấm icon extension trong Chrome, kiểm tra "Địa chỉ MCP server" đã đúng ws://127.0.0.1:<port>/ws?token=<token trong ~/.ccchrome.json> chưa, bấm "Lưu & kết nối lại" nếu cần.
  - > 0 → extension đã nối, báo thành công.
Kiểm tra thêm claude mcp get chrome để xác nhận MCP server chrome đã đăng ký cho Claude Code (registered bởi install.sh). Chưa có → gợi ý chạy lại /ccchrome install.
Tóm tắt ngắn gọn: bridge sống/chết, extension nối/chưa, MCP đã đăng ký/chưa.

`install`

Mục tiêu: chỉ đường, không tự chạy gì cả — cài đặt ghi vào $HOME và cài một dịch vụ nền, việc đó người dùng phải tự quyết định chạy khi nào.

In ra đúng lệnh sau và dừng, không thực thi:

curl -fsSL https://github.com/TranHuyQn/cc-chrome-extension/releases/latest/download/install.sh | bash

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ccchrome is a command published in the GitHub repository TranHuyQn/cc-chrome-extension (4 stars, last pushed 9d ago), licensed MIT. It adds 24 tokens to every session and 2,064 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
