## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (3)

Removes, cancels or revokes something. Claude Code: deny.

### `fillout_create_submissions`

- The name "fillout_create_submissions" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Create up to 10 new submissions on a form, as if respondents had filled it in — e.g. to import responses collected elsewhere. Each submission needs its question answers (question ids from fillout_get_form); URL parameters, scheduling, payments, login email and timestamps are optional. Creates real records that trigger the form's integrations. Fillout: POST /forms/{formId}/submissions.
```

### `fillout_create_webhook`

- The name "fillout_create_webhook" says "create": a word for a change.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Subscribe a URL to a form's new submissions: Fillout will POST each submission (same shape as a fillout_list_submissions entry) to it. Returns the webhook id — keep it, it is the only handle for removing the webhook later. Fillout: POST /webhook/create.
```

### `fillout_remove_webhook`

- The name "fillout_remove_webhook" says "remove": a word for removing or ending something.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Stop a webhook from receiving submissions. Recoverable: create it again with fillout_create_webhook (it gets a new id). Fillout: POST /webhook/delete.
```

## Only reads (6)

Looks things up and changes nothing. Claude Code: allow.

### `fillout_count_submissions`

- The name "fillout_count_submissions" says "count": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Count a form's submissions matching the same filters as fillout_list_submissions (date range, status, search) without pulling the answers — e.g. 'how many responses this week?' or 'how many partial submissions?'. Reads totalResponses from GET /forms/{formId}/submissions with limit=1.
```

### `fillout_export_submissions`

- The description's first verb is "fetch": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch many submissions in one call by walking the offset pagination (150 per page, paced under Fillout's 5 requests/second limit), up to max_submissions. Same filters as fillout_list_submissions. Use this for analysis across a whole response set; the result says whether it was truncated. Fillout: GET /forms/{formId}/submissions (repeated).
```

### `fillout_get_form`

- The name "fillout_get_form" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch one form's metadata: every question (id, name, type), calculations, URL parameters, scheduling and payment fields, and quiz settings. Use the question ids to read answers or to create submissions. Fillout: GET /forms/{formId}.
```

### `fillout_get_submission`

- The name "fillout_get_submission" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch a single submission by id, with every answer. Fillout: GET /forms/{formId}/submissions/{submissionId}.
```

### `fillout_list_forms`

- The name "fillout_list_forms" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List every form in the Fillout account — each form's name and formId. Start here to find the formId the other tools need. Fillout: GET /forms.
```

### `fillout_list_submissions`

- The name "fillout_list_submissions" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
List one page of a form's submissions (answers to every question, calculations, URL parameters, scheduling, payments, quiz score, login email), filtered by date range, status or free-text search. Offset pagination: the response carries totalResponses and pageCount. Fillout: GET /forms/{formId}/submissions.
```
