Obsidian MCP server

This is a small helper that connects your AI assistant to your Obsidian notes. Obsidian is a note-taking app that keeps your notes as plain text files in a folder on your computer. If you keep notes there, this helper lets your AI look through them and, if you allow it, make changes for you.

What this MCP server does

You ask your AI something about your notes, like finding a topic or adding a new note. The AI passes that request to this helper program running quietly on your computer. The helper opens the markdown files in your Obsidian folder directly, without needing the Obsidian app open. It reads, searches, or writes what you asked for, then hands the result back to the AI. The AI shows you the answer or confirms the change in the chat.

• Create and edit Obsidian Bases, which are database-style views over your notes

Try asking your AI

• “Find all my notes about the Q3 launch and summarize them”
• “Create a new note called Meeting Notes 2025-06-01 in my Work folder with today's date”
• “What tags do I use most often in my vault?”
• “Add a checkbox task to my daily note for tomorrow”

What it gives back to you

You get answers in the chat, like a list of matching notes, a summary, or a count of tags. When it creates or changes a note, it tells you what it did and where the file is. If you turned on backups, it quietly saves a copy of the old version first. You can also ask it to write a report back into your vault as a new note.
