What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• formstack_list_forms

  List the forms in the account, with submission counts, live URL and folder. Filter by name or folder and sort. Formstack: GET /forms.

• formstack_get_form

  Fetch a form's details — name, URL, submission counts, settings — optionally with its full field list. Formstack: GET /forms/{formId}.

• formstack_list_form_fields

  List every field on a form — id, label, type, required flag, options and logic. Use this to learn field IDs before searching or creating submissions. Formstack: GET /forms/{formId}/fields.

• formstack_list_form_submissions

  List a form's submissions, newest or oldest first, filtered by keyword, date range or specific field values. Set include_data to get the answers. Formstack: GET /forms/{formId}/submissions.

• formstack_count_form_submissions

  Count a form's submissions, with a per-day breakdown over a lookback window of up to 7 days. Formstack: GET /forms/{formId}/submissions/count.

• formstack_search_submissions

  Full-text search for submissions across every form in the account, e.g. by a person's email or name. Formstack: GET /submissions.

• formstack_get_submission

  Fetch a single submission with every field's label, type, display value and parsed value, plus payment, approval and workflow status. Formstack: GET /submissions/{submissionId}.

• formstack_delete_submission

  Permanently delete ONE submission and all associated data. First call with submission_id and its expected form_id to preview. Show the preview to the user and obtain their explicit confirmation, then call the SAME ids with confirm:true and the returned preview_token within 15 min

• formstack_list_partial_submissions

  List entries respondents started but did not finish (Save & Resume / abandoned), with the same filters as submissions. Formstack: GET /form/{formId}/partialsubmission.

• formstack_list_folders

  List the account's form folders and their subfolders. Formstack: GET /folders.

• formstack_get_folder

  Fetch a folder with its parent, permissions and direct subfolders. Formstack: GET /folders/{folderId}.

• formstack_list_webhooks

  List the webhooks that push a form's submissions to external URLs, with their payload settings. Formstack: GET /forms/{formId}/webhooks.

• formstack_list_notification_emails

  List the notification emails that alert your team when a form is submitted — recipients, subject, sender and logic. Formstack: GET /forms/{formId}/notifications.

• formstack_list_confirmation_emails

  List the confirmation emails sent to the person who submits a form — sender, subject, message and delay. Formstack: GET /forms/{formId}/confirmations.

• formstack_list_submit_actions

  List what happens after a form is submitted — default processing, a custom message, or a redirect URL — with conditional logic. Formstack: GET /forms/{formId}/submitactions.

• formstack_create_submission

  Submit an entry to a form on someone's behalf. This is a real submission: it counts toward the form and can fire its notification emails, webhooks and integrations. Formstack: POST /forms/{formId}/submissions.

• formstack_update_submission

  Change field values on an existing submission, or mark it read/unread. Only the fields you pass are changed. Formstack: PUT /submissions/{submissionId}.

• formstack_create_prefill_url

  Generate a link to a live form with some fields already filled in — e.g. to send a customer a form with their name and account number pre-entered. Formstack stores the prefill and returns prefilledUrl. Formstack: POST /forms/{formId}/prefill.

• formstack_update_form

  Rename a form, move it to a folder, change its submit-button text, timezone or language, or activate/deactivate it (with a message shown while inactive). Reversible. Formstack: PUT /forms/{formId}.

• formstack_create_folder

  Create a folder for organising forms, at the root or inside a parent folder. Formstack: POST /folders.

• formstack_create_webhook

  Add a webhook that POSTs each new submission of a form to your URL. Formstack: POST /forms/{formId}/webhooks.
