Overview

ButlerBrain

Persistent semantic memory for AI assistants, over the Model Context Protocol.

Save a thought, document, web page, or PDF to your brain once — then recall it by meaning from Claude, ChatGPT, or any MCP-compatible client. One memory, every AI, no re-explaining.

What you can do

  • Save anything — notes and thoughts, full web pages, PDFs, and calendar events
  • Recall by meaning — semantic vector search across everything you've saved, not just keyword matching
  • Use it everywhere — the same brain is available in Claude, ChatGPT, and any client that speaks MCP
  • Bring your own knowledge — sync an Obsidian vault, crawl web pages, or ingest documents

Tools

  • save_thought — save a note or piece of information to your brain
  • search_brain — semantic search across everything you've saved
  • get_context — pull broader context on a topic across all your notes
  • get_person — find everything you've saved that mentions a person
  • crawl_and_save — crawl a web page and store it for later recall
  • ingest_pdf / get_upload_url — add PDFs and documents to your brain
  • add_event / get_events / delete_event — lightweight calendar memory

Works with

Claude · ChatGPT · Cursor · Windsurf · any MCP-compatible client.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
