The tools it lists (67, as of 5 days ago)

The tool-description rules found nothing in these descriptions. They look for instructions aimed at a model and for hidden characters; they cannot see what a tool does when it runs.

• list_clients

  List the entities (companies) this credential can work with. Call this first to resolve the client_id every other tool needs. Returns each entity id and name.

• create_client

  Create a new entity (company) in the organization. Requires a Manager-role key. Use only when the user explicitly asks to set up a new entity; show them the name you will create first.

• upload_trial_balance

  Stage a Trial Balance spreadsheet (xlsx or csv, max 4 MB) for an entity by INLINING its bytes as base64. This path is ONLY for programmatic callers (a script, Claude Code, an automation) that already have the raw file on disk. If a HUMAN has the file — e.g. they attached it to this chat — do NOT use this tool and do NOT base64-encode the file: call create_upload_link instead and give them the link to upload it in their browser. File size does not change this: even a small attached file goes through create_upload_link — inlining a human-supplied file is unreliable and its bytes routinely trunca

• get_upload

  Read an upload session: status, detected header row and columns, the confirmed mapping (if any), and the stored validation outcome. Use to check what a staged upload still needs.

• set_header_row

  Correct the detected header row of a staged upload (1-based). Only needed when get_upload/upload_trial_balance shows the wrong row was detected.

• confirm_column_mapping

  Confirm the column→field mapping for a staged upload and run validation. Returns the full validation result (row counts, warnings, blocking issues). Mapping suggestions are never auto-applied — pass exactly the mapping your user approved. Review any warnings with your user before ingesting.
