uc-mcp-server

An MCP (Model Context Protocol) server for programmatically interacting with the UnknownCheats forum. Bypasses Cloudflare protection using a real Chrome instance and provides structured data extraction via Cheerio.

Features

• Cloudflare bypass — Uses puppeteer-real-browser with a headed Chrome instance to solve Turnstile challenges automatically

• Cookie persistence — Session cookies saved to cookies.json and reused across restarts

• Auto-recovery — Detects detached frame / browser crash errors and relaunches automatically

• 6 MCP tools — Login, search, thread reading, pagination, code extraction, and debug

Tools

extract_code details

When the limit is hit, the response includes truncated: true, last_post_id (so you know where to resume), and a hint on how many blocks were skipped. Each block also carries a postId so you can trace it back to the exact post on the page.

Stack

• Runtime: Bun

• Language: TypeScript (ESM)

• Protocol: @modelcontextprotocol/sdk

• Browser: puppeteer-real-browser

• Parsing: cheerio

Requirements

• Bun v1.0+

• Google Chrome installed (required by puppeteer-real-browser)

Installation

# via npm
npx uc-mcp-server

# or clone
git clone https://github.com/amaralkaff/mcp-unknowncheat.git
cd mcp-unknowncheat
bun install

Setup with Claude Code

claude mcp add uc-mcp bun -- run "/path/to/mcp-unknowncheat/src/index.ts"

Or with npx:

claude mcp add uc-mcp npx -- uc-mcp-server

Setup with Claude Desktop

Add to %APPDATA%\Claude\claude_desktop_config.json (Windows) or ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "uc-mcp": {
      "command": "npx",
      "args": ["uc-mcp-server"]
    }
  }
}

Usage

On first run, Chrome opens in headed mode. Log in manually or use the login tool:

login({ username: "your_username", password: "your_password" })

Cookies are saved automatically. Subsequent runs reuse the session.

Examples

# Check login status
check_login()

# Browse the Apex Legends subforum
search_forum({ subforum: "apex-legends" })

# Search across all forums
search_forum({ query: "pubg offsets" })

# Get a thread (single page)
get_thread({ url: "https://www.unknowncheats.me/forum/..." })

# Get all pages of a thread
get_thread({ url: "https://www.unknowncheats.me/forum/...", fetch_all_pages: true })

# Extract code blocks (up to 10 inline)
extract_code({ url: "https://www.unknowncheats.me/forum/..." })

# Extract all code blocks and save to file
extract_code({ url: "https://www.unknowncheats.me/forum/...", export_to_file: true })

Notes

• All logging uses console.error() — console.log() is reserved for the MCP stdio transport

• Thread pagination capped at 50 pages by default for fetch_all_pages

• Language detection supports: C++, C#, Python, Lua

• Exported files are saved to ./exports/ and are excluded from git and npm
