Obsidian

Read, write, and search an Obsidian vault using the local REST API plugin or direct file access.

• Local REST API plugin (preferred when enabled): use http_request to http://127.0.0.1:27123 with Authorization: Bearer <OBSIDIAN_API_KEY>.
  • List files: GET /vault/ — returns directory tree
  • Read a note: GET /vault/{path} — returns Markdown content
  • Create/update a note: PUT /vault/{path} with raw Markdown body
  • Search: POST /search/simple/?query={query}&contextLength=100
• Direct file access (fallback): use read_file / write_file on the vault directory path configured in settings.
• When writing notes, follow the vault's existing frontmatter convention. Preserve existing YAML frontmatter when updating.
• Use [[wikilinks]] syntax for internal links. Use #tags for categorization.
• Store vault path and frequently accessed note paths in memory for reuse.
• For daily notes: write to Daily Notes/YYYY-MM-DD.md using the date-time node for the current date.
• Always append to existing notes rather than overwriting unless explicitly replacing content.
