add-tags
Add tags to notes in frontmatter and/or content.
How to use it
Project documentation lists add-tags for the Obsidian MCP Rs MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.

Read the content of an existing note.
Remove tags from notes.
Rename a tag across all notes in the vault.
Search notes by content, filename, or tag. Results are BM25-ranked, best-first, and paged.
