HTTrack MCP Server

Máy chủ FastMCP bọc HTTrack: các tác nhân AI sao chép toàn bộ trang web vào kho lưu trữ ngoại tuyến cục bộ (các tác vụ nền) rồi duyệt, đọc và tìm kiếm các trang đã tải xuống qua MCP. Mỗi dự án có một bản sao cách ly riêng với bảo vệ đồng thời.

HTTrack MCP Server

A FastMCP (Model Context Protocol) server that wraps the classic HTTrack website copier, so AI agents can mirror websites into a shared archive and then browse, read, and search the downloaded content — all over MCP.

Why

HTTrack is battle-tested for offline website copying, but it has no scripting API — only a GUI and a CLI. This server makes it agent-native: an LLM agent can call mirror_site to start a download in the background, poll mirror_status, and later answer questions from the archive via catalog, list_files, read_file, and search_files.

Tools

Tool	Purpose
`mirror_site(url, project, depth, max_rate, filters)`	Start a background mirror into the archive (`/data/<project>`). One active mirror per project — a concurrent request for the same project returns `already_running` with the live `job_id`; different projects run in parallel.
`mirror_status(job_id)`	Job status (`running` / `done` / `failed` + log tail). Omit to list recent jobs; also accepts the project name.
`catalog()`	All projects: short name, short description (auto-derived from each site's `<title>`/meta description), source URL, status, page/file counts, size.
`list_files(project, subpath)`	Directory listing inside a project (name, type, size, modified).
`read_file(project, path, max_bytes)`	Read one text file (HTML/JS/CSS/txt/json/md). Refuses binaries; caps content at 256 KB to keep agent context sane.
`search_files(project, query, max_results)`	Case-insensitive substring search across a project's text files, capped results.

Quick start

Prerequisites: Docker.

docker build -t httrack-mcp-server .

docker run -d --name httrack-mcp --restart unless-stopped \
  -p 9050:8000 \
  -v /path/to/your/archive:/data:rw \
  httrack-mcp

The container exposes the MCP server over streamable HTTP at http://<host>:9050/mcp.

Register in an MCP client

Example for MCPHub-style gateways (streamable-http):

{
  "httrack": {
    "type": "streamable-http",
    "url": "http://192.168.1.35:9050/mcp",
    "enabled": true,
    "description": "HTTrack site mirroring + archive browsing",
    "owner": "admin"
  }
}

Clients that speak streamable HTTP directly can connect to /mcp with no extra auth (nobody is authenticated; run this on a trusted network, or put it behind your gateway's auth). See HELP.md for full usage, examples, and troubleshooting.

Concurrency model

One httrack process per project, isolated by its own output directory — no shared state between projects, so multiple agents can mirror different sites in parallel.
mirror_site guards against double-mirroring the same project (in-process job table + a /proc scan for httrack processes writing to that project directory).

CI

GitHub Actions runs on every PR and push: Python syntax check of server.py, Dockerfile sanity assertions, and a Docker image build.
