• authAuthenticate with Quadraticcan change or delete data

  Authenticate the MCP session with Quadratic. Actions: • login() — Start an OAuth device authorization flow. Returns a URL the user must open in a browser to authorize. The flow is completed by confirm_login. • confirm_login(device_code) — Complete an in-progress login by polling for user authorization. If the response indicates the user has not yet authorized, this action can be called again with the same device_code to continue polling. confirm_login is idempotent: if a later tool call reports "Not authenticated on this connection", call confirm_login again with the same device_code to re-es…

• files_readRead Quadratic Filesread-only

  Read-only file metadata operations on Quadratic files the user has access to. No data is modified. Requires authentication. Actions: • list_files() — List all accessible files. • get_file_info(file_id) — Get metadata for a single file.

• files_writeManage Quadratic Filescan change or delete data

  File management operations that create or modify state: create a new file, open an existing file to start an editing session, or close a session. Requires authentication. Actions: • open_file(file_id?, file_name?) — Open a file by UUID or name and start an editing session. Returns the file's web URL. • create_file(file_name, team_uuid?) — Create a new blank spreadsheet. If team_uuid is omitted, the user's first team is used. Returns the new file's UUID and web URL; the file must be opened with open_file before it can be edited. • close_file(file_id) — Close an active editing session.

Special actions (not shown in the action enum): • batch — {"action": "batch", "params": {"actions": [{"action": "<name>", "params": {...}}, ...]}}. Runs reads in parallel; individual failures are reported per-entry without short-circuiting. • context — {"action": "context", "params": {"topic": "<name>"}} or {"action": "context", "params": {"action": "<name>"}}.

• write_dataWrite Spreadsheet Datacan change or delete data

  Write operations on the open spreadsheet. Call as {"action": "<name>", "params": {...}} — per-action params are listed in the Action Reference below. Numbers, booleans, and nulls in cell values are coerced to strings. Special actions (not shown in the action enum): • batch — {"action": "batch", "params": {"actions": [{"action": "<name>", "params": {...}}, ...]}}. Runs writes sequentially; errors short-circuit the batch. • context — {"action": "context", "params": {"topic": "<name>"}} or {"action": "context", "params": {"action": "<name>"}}. Returns deeper docs for a topic or a single action's…
