knack_list_objectsread-only

List an application's objects (tables) as a compact array [{ key, name, fieldCount }]. Convenience over GET /applications/{app_id}. app_id defaults to the configured KNACK_APPLICATION_ID.

knack_list_fieldsread-only

List the fields of ONE object as [{ key, name, type, required }]. Fetches GET /applications/{app_id} and returns the fields of the object whose key === objectKey (e.g. "object_1"). app_id defaults to the configured KNACK_APPLICATION_ID.

knack_list_recordsread-only

List an object's records. Knack API: GET /objects/{object_key}/records. Returns the paged envelope { total_pages, current_page, total_records, records: [...] } as-is. Records carry both field_x (formatted) and field_x_raw (structured) values. Page with page / rows_per_page (max 1000), sort with sort_field / sort_order, and filter with the `filters` object.

knack_get_recordread-only

Fetch a single record by id. Knack API: GET /objects/{object_key}/records/{record_id}. Returns the bare record (with both field_x and field_x_raw values).

knack_requestread-only

Power-user escape hatch: GET any Knack API path not wrapped by a dedicated tool (e.g. view-based reads). READ-ONLY — only GET is allowed. Path starts with a slash (e.g. "/objects/object_1/records"). Knack API: GET {path}.

knack_create_recordcan modify

MUTATES Knack data — creates a new record in an object. Knack API: POST /objects/{object_key}/records. Provide `fields` as an object keyed by field key, e.g. { "field_1": "Acme", "field_2": 100 }. Auto Increment / Formula / Equation fields are read-only and cannot be set. Returns the created record.

knack_update_recordcan modify

MUTATES Knack data — updates a record. Knack API: PUT /objects/{object_key}/records/{record_id}. Provide `fields` as an object keyed by field key; only the included fields change, e.g. { "field_1": "Acme Inc" }. Auto Increment / Formula / Equation fields are read-only. Returns the updated record.

knack_delete_recordcan modify

MUTATES Knack data — permanently DELETES a record (irreversible). Knack API: DELETE /objects/{object_key}/records/{record_id}. Knack returns { delete: true } on success.
