Requirements

• Python ≥ 3.10
• mcp[cli] ≥ 1.0.0
• playwright ≥ 1.42.0
• uv (recommended) or pip

Installation

1. Install the package

# 1. Clone and enter the directory
git clone https://github.com/Mol2017/rednote-mcp.git
cd rednote-mcp-python

# 2. Create a virtual environment and install dependencies
uv venv && source .venv/bin/activate
uv pip install -e .

# 3. Install Playwright browsers
playwright install chromium

2. Add to Claude and verify

# Register the MCP server with Claude
claude mcp add rednote .venv/bin/rednote-mcp

# Verify it is connected
claude mcp list

3. Debug

# Activate the virtual environment
source .venv/bin/activate

# Launch the MCP dev inspector
mcp dev src/rednote_mcp/server.py

First-time login

Ask the agent to log in to RedNote. It opens a real Chrome window with a QR code — scan it with the RedNote app. Cookies are persisted to ~/.mcp/rednote/cookies.json and reused automatically for all future calls.

Anti-bot detection

Mitigations included: persistent browser session, realistic Chrome 131/macOS fingerprint (viewport 1440×900, locale zh-CN, timezone Asia/Shanghai), random delays between actions, and incremental scrolling.

If tools return empty results (bot detection triggered): call set_browser_mode(headless=False), then login(force=True), scan the QR code, and retry.
