## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (3)

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

### `falai_cancel_request`

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

Description, as the server wrote it:

```untrusted-server-text
Request cancellation of a queued (not-yet-started) request. Returns 202 { status: 'CANCELLATION_REQUESTED' }. fal.ai queue: PUT {queue}/{model_id}/requests/{request_id}/cancel.
```

### `falai_run_model`

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

Description, as the server wrote it:

```untrusted-server-text
Convenience 'subscribe': submit a request, poll its status until COMPLETED, then return the result. Consumes fal credits. If it does not complete within the wait budget, returns a { status, request_id, status_url, note } object (NOT an error) so you can keep polling with falai_get_request_status / falai_get_request_result.
```

### `falai_submit_request`

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

Description, as the server wrote it:

```untrusted-server-text
Submit an inference request to the queue and return immediately (async — does NOT wait for completion). Returns { request_id, response_url, status_url, cancel_url, queue_position }. Consumes fal credits when the model runs. fal.ai queue: POST {queue}/{model_id} with body = the model input.
```

## Only reads (4)

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

### `falai_get_model_schema`

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

Description, as the server wrote it:

```untrusted-server-text
Get the OpenAPI 3 schema for a model — its input/output fields (components.schemas). Use this to learn what inputs a model accepts before submitting. fal.ai API: GET /openapi/queue/openapi.json?endpoint_id={model_id}.
```

### `falai_get_request_result`

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

Description, as the server wrote it:

```untrusted-server-text
Get the final output of a COMPLETED queued request. fal.ai queue: GET {queue}/{model_id}/requests/{request_id}.
```

### `falai_get_request_status`

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

Description, as the server wrote it:

```untrusted-server-text
Get the status of a queued request (IN_QUEUE | IN_PROGRESS | COMPLETED). fal.ai queue: GET {queue}/{model_id}/requests/{request_id}/status (optional logs=1).
```

### `falai_list_models`

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

Description, as the server wrote it:

```untrusted-server-text
List or search fal.ai models in the registry (paginated). fal.ai API: GET /models (query: keywords, page, total).
```
