Obsidian
Your notes, searched, read and written by your AI
bitbonsai (mcpvault) · MIT · free
Your AI searches your Obsidian notes, reads a note, lists folders and tags, and - when you allow it - creates and edits notes. It works on the notes folder directly, so there is no Obsidian plugin to install and Obsidian does not need to be open. One switch also keeps those notes among the documents of each AI that uses the tool, so the AI remembers them in every chat.
"Add to Your Own AI" opens the app with this ready to add (the app must be installed). Or in the app: Add-ons › Tools › Obsidian › Add. Then give it to an AI under Tools.
This tool comes with the app - nothing to fetch from the directory. The server it runs on is fetched the first time an AI uses it.
What it needs
The app checks these for you and installs what it can with one click; the links are the manual route.
- Node.js 20 or newer (runs the tool) - install
- Starts read only: your AI can look but not change anything until you switch that off in the tool's settings. The first session fetches the tool itself (mcpvault 0.16.0, a few MB) from the npm registry, so that first start takes a little longer. Notes you clip from the web can carry instructions meant for an AI: keep Approvals on when you allow writing.
Settings you will be asked for
The app asks for these when you add the tool. They stay on your computer - secrets encrypted - and go only to this tool.
- Your Obsidian notes folder - the folder you opened in Obsidian
- Read only - your AI can look, but not change or delete notes (on to begin with) - a switch
- Also remember these notes - read them into the documents of each AI that uses this tool, and keep them in sync (on to begin with) - a switch
