Gemini MCP Bridge

A Model Context Protocol (MCP) server that bridges to Gemini's web chat interface, providing real-time streaming of both the thinking process and responses. Features advanced stealth capabilities, proxy rotation, fingerprint evasion, and session persistence.

Features

• Real-time Streaming: Capture Gemini's thinking process and response tokens as they generate

• Stealth Browser: Advanced fingerprint evasion using Playwright with stealth plugins

• Proxy Rotation: Automatic proxy health checks and rotation with multiple source support

• Session Persistence: Cookies, localStorage, and sessionStorage saved/restored across runs

• Fingerprint Randomization: Canvas, WebGL, audio, fonts, and navigator spoofing

• MCP Protocol: Full MCP server with tools, resources, and prompts

• No API Key Required: Uses web interface automation (respects ToS)

Proxy Configuration

Add proxies to proxies.txt:

http://user:pass@host:port
socks5://host:port
host:port

Or configure API sources in config/settings.yaml:

proxy:
  sources:
    - type: "api"
      url: "https://your-proxy-api.com/getproxies"

Session Persistence

Sessions are saved to ./session/:

• cookies.json - Browser cookies

• local_storage.json - localStorage data

• state.json - Full session state

Logging

Logs written to ./logs/gemini_mcp.log with rotation.

Troubleshooting

Chat not loading

• Check selectors in config/settings.yaml match current Gemini UI

• Increase timeouts if on slow connection

• Try disabling headless mode to debug

Proxy issues

• Verify proxies in proxies.txt are working

• Check proxy authentication format

• Disable proxy in config if not needed

Detection issues

• Enable all stealth features in config

• Use residential proxies for better results

• Rotate user agents and fingerprints
