Read the full markdown content of a note in the vault. Path is relative to the vault root; the .md extension is optional. Read-only.

Create a new note or overwrite an existing one. Refuses to overwrite unless overwrite=true. Parent folders are created automatically.

Append markdown to the end of a note, creating it if it does not exist. A newline is inserted before appended content when the note already has content.

List markdown notes in the vault, optionally scoped to a folder. Hidden folders (.obsidian, .git) are skipped. Read-only.

Case-insensitive full-text search across note bodies. Returns matching file path, line number, and the matching line. Read-only.

Parse and return the YAML frontmatter of a note as structured data, plus a short body preview. Read-only.

Extract [[wikilinks]] from a note and resolve each to an actual vault file by basename. Handles [[Note|alias]] and [[Note#heading]]. Unresolved links return target=null. Read-only.
