Obsidian MCP server

This is a small helper that connects your AI assistant to your Obsidian notes. Once it is set up, you can ask your AI to look things up in your vault or make changes to your notes for you. It is handy if you keep your ideas, projects or research in Obsidian and want your AI to work with them directly.

What this MCP server does

You ask your AI something about your notes, like reading one or searching for a word. The AI passes your request to this helper program. The helper opens your Obsidian vault folder and does the work, such as reading a note, searching across files, or writing new content. Then it sends the result back, and your AI shows it to you in the chat. Obsidian itself does not need to be open for this to work.

Try asking your AI

• “What files are in my Obsidian vault?”
• “Read my note called project-ideas.md”
• “Create a new note called meeting-notes.md with today's date”
• “Add the tags project and urgent to my task note”

What it gives back to you

You get answers in plain chat text: the content of a note, a list of files, a list of tags, or a short message saying a change was made. For searches, it gives you the matching notes and the relevant lines. When it writes or edits, it tells you what it did, like which note was updated and in which mode.
