What is Cursor Chat History Vectorizer & Dockerized Search MCP?
This server extracts user prompts from Cursor IDE’s local SQLite databases, generates embeddings via a local Ollama instance (using nomic-embed-text), stores them in a LanceDB vector database, and provides a Dockerized FastAPI API for vector similarity search. It is designed for developers who want to make their Cursor chat history searchable for Retrieval Augmented Generation (RAG) or LLM-based analysis.
How to use Cursor Chat History Vectorizer & Dockerized Search MCP?
Two main steps: (1) Run python cursor_history_extractor.py on your host machine to create or update the LanceDB database at ./cursor_chat_history.lancedb. (2) Build the Docker image with docker build -t cursor-chat-search-api . and run the container with docker run -p 8001:8001 -v /absolute/path/to/cursor_chat_history.lancedb:/data/cursor_chat_history.lancedb -e OLLAMA_HOST="http://host.docker.internal:11434" cursor-chat-search-api. The search API will be accessible at http://localhost:8001.
