About Lcbro MCP

Cost Optimization Focus: This project is specifically designed to optimize LLM request costs and reduce context usage by intelligently preprocessing and cleaning data using local LLM models before sending to expensive main LLM APIs. This approach can reduce costs by up to 80% while improving result quality.

Features

  • Real browser control with JavaScript execution

  • Login flows, clicks, text input, form handling

  • Screenshot capture and content extraction

  • Session management with persistent contexts

  • Auto-generates preprocessing prompts

  • Local LLM integration (Ollama, JAN)

  • Smart content analysis and optimization

  • Cost-efficient data preparation

  • Playwright: Full-featured automation

  • CDP: Chrome DevTools Protocol support
