Tools

Functions exposed to the LLM to take actions

NameDescription
dt3_statusA

Check DEVONthink 3 readiness and scope configuration. Does not launch the app.

dt3_databasesA

List permitted currently open databases and their root UUIDs. Refresh as databases open/close. Run the local setup CLI to change access policy.

dt3_selectionA

Read metadata for the current DEVONthink selection, filtered by access policy.

dt3_searchA

Search one permitted database with native DEVONthink query syntax, e.g. name:report or tag:review. Metadata only; use read_text for content. Live pagination follows native result order.

dt3_list_groupA

Browse direct children, including empty groups and records without indexed text. Follow next_offset to continue.

dt3_get_recordA

Read document metadata and a revision for safe editing. Optionally include custom metadata (16,000-character limit). Original paths and binary bytes are not exposed.

dt3_read_textA

Read a bounded chunk of DEVONthink indexed plain text with citation and extraction status. No OCR, transcription, or spreadsheet recalculation is performed.

dt3_relatedA

Find native similar documents, classification suggestions, duplicate files, or incoming/outgoing item references. Results are permission-filtered. Suggestions are advisory; duplicate detection follows DEVONthink, not a fresh disk hash.
