frontmatter
Read or write any YAML frontmatter key — not just tags. Writes are line surgery on the one key named, so the rest of the block (comments, key order, quoting) survives byte for byte.
How to use it
Project documentation lists frontmatter 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.
