## What it does

Stellavault hands your notes folder to the agent as a source: semantic and keyword search, questions answered from the vault, drafts, link checks. It runs over stdio and computes embeddings on your machine, so nothing is sent to a cloud service and no keys are involved. Your original files stay untouched.

For Claude the quick route is `claude mcp add stellavault -- npx -y stellavault`. To pin the database to a known location, add the variable: `claude mcp add --env STELLAVAULT_DB_PATH=<STELLAVAULT_DB_PATH> --transport stdio stellavault -- npx -y stellavault`. Node.js 20 or newer is required — older runtimes won't start the server.

Without `STELLAVAULT_DB_PATH` the index lands wherever the server picks, which is awkward if you keep vaults in separate folders. Cursor, GitHub Copilot and Gemini CLI each get their own config: a JSON block under `mcpServers` or `servers`, or the `gemini mcp add` command.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `STELLAVAULT_DB_PATH` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- find a note by meaning instead of an exact phrase
- ask a question across the whole vault and get notes back as sources
- draft something new from material you already wrote
- spot contradictions and duplicates between notes
- give an agent access to a personal vault without uploading it

## Example prompts
- Search my vault for notes about release planning and show the three closest
- What do I have on caching? Answer with links to the notes
- Draft an article about local embeddings from my own notes
