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.
