## MCP tools (9)

### `create_sheet` (~48 tokens)

Create CSVBox Sheet

Create a new CSVBox sheet via POST /1.1/sheet. Input: { sheet }. Returns the API response.

Input parameters:

- `sheet` (object, required): The full CSVBox sheet object to create.

### `update_sheet` (~175 tokens)

Update (Replace) CSVBox Sheet

Replace an existing CSVBox sheet via PUT /1.1/sheet/{sheet_license_key}. Input: { sheet_license_key, sheet }. Returns the API response. DESTRUCTIVE: PUT is authoritative for every collection it sends — items listed are created or updated in place, and any existing item the array does not name is DELETED. This applies to virtual_columns, validation_functions and data_transforms: sending an empty array DELETES ALL of that collection's items, while OMITTING the key leaves them untouched. `_delete` is not valid here; use patch_sheet to remove a single item. Run validate_schema with mode 'put' first to catch a destructive body.

Input parameters:

- `sheet` (object, required): The full replacement CSVBox sheet object.
- `sheet_license_key` (string, required): The license key of the sheet to replace.

### `patch_sheet` (~186 tokens)

Patch CSVBox Sheet

Partially update a CSVBox sheet via PATCH /1.1/sheet/{sheet_license_key}. Sends only the changes object. Input: { sheet_license_key, changes }. Returns the API response. PATCH MERGES: only the items you list are touched and nothing is deleted implicitly, so an empty array is a no-op. Items in virtual_columns, validation_functions and data_transforms are matched by column_name / function_name / transform_name respectively — an unmatched name creates a new item. To remove one, send it with `_delete: true`; every other field on a _delete item is ignored, including js_code. This is the safe verb for applying generated functions. Run validate_schema with mode 'patch' first.

Input parameters:

- `changes` (object, required): Only the partial changes to apply to the sheet.
- `sheet_license_key` (string, required): The license key of the sheet to patch.

### `generate_sheet_json` (~135 tokens)

Generate CSVBox Sheet JSON

Generate a COMPLETE CSVBox sheet (title, sheet_columns, destinations, webhooks, security_settings, steps) from a natural-language prompt using a configured LLM. Does NOT call the CSVBox API. Returns { sheet, source, validation }. Requires ANTHROPIC_API_KEY or OPENAI_API_KEY; without one it returns an error pointing to the create_csvbox_sheet MCP prompt. Input: { prompt }.

Input parameters:

- `prompt` (string, required): Natural-language description of the importer, e.g. "Create employee importer with columns name, email, salary, joining date; destination as testapi; allow only xlsx files".

### `create_importer_from_prompt` (~125 tokens)

Create Importer From Prompt

Generate a COMPLETE CSVBox sheet from a natural-language prompt via a configured LLM, validate it locally, then create it via POST /1.1/sheet. Returns { generated_schema, source, validation, api_response }. Aborts (no API call) if no LLM provider is configured or if validation fails. Requires ANTHROPIC_API_KEY or OPENAI_API_KEY plus CSVBox credentials.

Input parameters:

- `prompt` (string, required): Natural-language description of the importer, e.g. "Create customer importer with columns name, email, phone; allow for example.com".

### `generate_import_code` (~124 tokens)

Generate CSVBox Integration Code

Generate complete CSVBox importer integration code for a framework (vanilla-js, react, vuejs2 [Vue 2], vuejs3 [Vue 3], angular [Angular 8-13], angular2 [Angular 14+]). Input: { framework }. Replace the license key placeholder with your sheet's license key.

Input parameters:

- `framework` (string, required): Target framework: vanilla-js | react | vuejs2 (Vue 2) | vuejs3 (Vue 3) | angular (Angular 8-13) | angular2 (Angular 14+).

### `generate_sheet_functions` (~213 tokens)

Generate CSVBox Sheet Functions

Author CSVBox virtual_columns, validation_functions, and data_transforms from a natural-language prompt using a configured LLM. Does NOT call the CSVBox API — it returns JSON so you can REVIEW the generated JavaScript before applying it with patch_sheet. Collections the request does not imply are omitted, never returned as empty arrays. Returns { virtual_columns?, validation_functions?, data_transforms?, source, validation }. Requires ANTHROPIC_API_KEY or OPENAI_API_KEY; without one it returns an error pointing to the csvbox_sheet_functions MCP prompt. Input: { prompt, sheet? }.

Input parameters:

- `prompt` (string, required): Natural-language description of the functions to author, e.g. "add a virtual column joining first and last name, and validate that every email contains an @".
- `sheet` (object): The existing sheet the functions will be applied to. Supplying it lets the model reference real column names and lets validation check those references. CSVBox exposes no read endpoint, so this must…

### `validate_schema` (~273 tokens)

Validate CSVBox Schema

Validate a CSVBox sheet schema locally (no API call). Requires a non-empty title; sheet_columns is optional (absent passes, empty yields a warning). When columns are present, checks for missing column_name/display_label/type, unsupported types, duplicate names, duplicate positions, and invalid dependent column references. Also checks virtual_columns, validation_functions, and data_transforms: per-sheet caps, duplicate and colliding names, missing or oversized js_code, scope/run_at enums, column references against sheet_columns, and dependency URLs (https, allowed CDN hosts, .js/.mjs, integrity digest). Pass mode ('create' | 'put' | 'patch', default 'create') so empty-array and _delete rules match the verb you are about to use. Returns { valid, errors, warnings }.

Input parameters:

- `mode` (string): Which write verb this payload is headed for. "create" (default) for POST, "put" for a full replace, "patch" for a partial update. Affects only the function collections: an empty array is an error und…
- `sheet` (object, required): The CSVBox sheet object to validate.

### `submit_file` (~311 tokens)

Submit File via CSVBox REST File API

Submit a file for import via POST /1.1/file. Provide exactly one of public_file_url (JSON submission) or file_base64 + file_name (multipart direct upload — file_base64 is decoded server-side and sent to CSVBox as true binary multipart content, never as a base64 string). Input: { sheet_license_key, public_file_url? | (file_base64?, file_name?), file_sheet_name?, user?, options?, dynamic_columns? }. Returns the API response.

Input parameters:

- `dynamic_columns` (array): Dynamic column definitions with validators.
- `file_base64` (string): Base64-encoded file content for direct upload. This is an MCP-transport-only encoding: the server decodes it into raw bytes and sends CSVBox a true multipart/form-data 'file' part, never a base64 str…
- `file_name` (string): File name for the direct upload. Required with file_base64.
- `file_sheet_name` (string): Worksheet name to import, for multi-tab files.
- `options` (object): Import options: has_header (0/1), max_rows, auto_map.
- `public_file_url` (string): Public URL of the file to import. Mutually exclusive with file_base64.
- `sheet_license_key` (string, required): The license key of the sheet to import into.
- `user` (object): Custom user reference object attached to the import.
