Tools & capabilities

MCP Obsidian tools 18

  • read_noteRead a note from the Obsidian vault
  • write_noteWrite a note to the Obsidian vault
  • patch_noteEfficiently update part of a note by replacing a specific string. This is more efficient than rewriting the entire note for small changes.
  • list_directoryList files and directories in the vault (includes non-note filenames, while read/write tools remain note-only)
  • delete_noteDelete a note from the Obsidian vault (requires confirmation). Supports permanent delete, vault trash, or system trash.
  • search_notesSearch for notes in the vault by content or frontmatter
  • move_noteMove or rename a note in the vault
  • move_fileMove or rename any file in the vault (binary-safe, file-only, requires confirmation)
  • read_multiple_notesRead multiple notes in a batch (max 10 files)
  • update_frontmatterUpdate frontmatter of a note without changing content
  • get_notes_infoGet metadata for notes without reading full content
  • get_frontmatterExtract frontmatter from a note without reading the content

  • find_stationSearch the ~17,000-station GuzzStations catalog by name, country, or coordinates. Optional `compact=True` returns just the newest TMYx per station (6–10× smaller responses for chained agent workflows).
  • analyze_weatherStatistical summary of an EPW. Three modes: `url=` (single file), `urls=[]` (2–10 file comparison), `config={...}` (synthesize a morphed scenario from lat/lon — no EPW content returned). Optional `include_full_ashrae`, `include_improbability`, `include_idf`.
  • chart_weatherInline SVG chart. Single-EPW types: `diurnal`, `temp_carpet`, `wind_rose`, `monthly_boxplot`, `utci_carpet`, `economizer_carpet`, `pv_tilt_azimuth`, `solar_under_events`. Multi-EPW type: `comparison`.
  • generate_weather_fileGenerate and return a downloadable weather file with the full morph stack. Format = `epw` / `ddy` / `csv` / `zip` / `pvsyst`. Supports `ensemble=true` (all SSPs at once).
