Pulled straight from the server with tools/list on 2026-10-18.
list_sheetsread-only

Discover sheet names and used dimensions before reading or editing a WorkPaper. Returns metadata only; use read_range or read_cell for values.

read_rangeread-only

Read calculated values plus serialized formulas/inputs for an A1 range. Use for audit readback after edits; use read_cell for one address.

read_cellread-only

Read one cell with calculated value, display text, formula text, formula diagnostics, and serialized content. Use after set_cell_contents to verify readback.

set_cell_contents

Write raw content to one cell and recalculate dependents in memory only. Start with --writable when the edit should persist to JSON.

set_cell_contents_and_readback

Write raw content to one cell, recalculate dependents, read a dependent range in the same tool call, and return persistence proof. Use this for stateless MCP clients such as hosted Open WebUI integrations.

get_cell_display_valueread-only

Return the formatted display string for one cell. Use when an agent needs what a user would see, not the raw numeric value.

export_workpaper_documentread-only

Export the current WorkPaper JSON document for persistence, review, or handoff to another agent. Does not write files by itself.

validate_formularead-only

Validate formula syntax with the WorkPaper parser before writing it to a cell. This checks syntax only; use set_cell_contents plus readback to evaluate.
