## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (6)

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

### `lambda_create_filesystem`

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

Description, as the server wrote it:

```untrusted-server-text
Create a new persistent filesystem in a region (can then be attached to instances at launch). Lambda Cloud REST: POST /api/v1/filesystems.
```

### `lambda_delete_filesystem`

- The name "lambda_delete_filesystem" says "delete": a word for removing or ending something.
- The description says "Irreversible".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Delete a persistent filesystem by id. Irreversible — DESTROYS all data on it. The filesystem must not be attached to any instance. Lambda Cloud REST: DELETE /api/v1/filesystems/{id}.
```

### `lambda_launch_instance`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Launch one or more GPU cloud instances. COSTS MONEY: billing starts as soon as the instance boots (hourly rate per instance_type). Pick region_name + instance_type_name from lambda_list_instance_types (only regions with capacity available), and pass exactly one existing SSH key name in ssh_key_names (create keys in the Lambda dashboard). Lambda Cloud REST: POST /api/v1/instance-operations/launch.
```

### `lambda_restart_instances`

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

Description, as the server wrote it:

```untrusted-server-text
Restart one or more running instances by id (a reboot — the instances are NOT destroyed and billing continues). Lambda Cloud REST: POST /api/v1/instance-operations/restart.
```

### `lambda_terminate_instances`

- The name "lambda_terminate_instances" says "terminate": a word for removing or ending something.
- The description says "permanently destroy".
- The server marks it destructive (destructiveHint: true).

Description, as the server wrote it:

```untrusted-server-text
Terminate (permanently destroy) one or more instances by id. This STOPS billing for them but DESTROYS the instances and any non-persistent data — persistent filesystems survive. Irreversible. Lambda Cloud REST: POST /api/v1/instance-operations/terminate.
```

### `lambda_update_instance`

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

Description, as the server wrote it:

```untrusted-server-text
Update a live instance's name and/or tags. Only provided fields are changed. Lambda Cloud REST: POST /api/v1/instances/{id}.
```

## Only reads (9)

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

### `lambda_get_firewall_ruleset`

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

Description, as the server wrote it:

```untrusted-server-text
Get a single firewall ruleset by id. Lambda Cloud REST: GET /api/v1/firewall-rulesets/{id}.
```

### `lambda_get_instance`

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

Description, as the server wrote it:

```untrusted-server-text
Get full details of a single instance by id (status, ip, region, instance_type, ssh/filesystem attachments, jupyter url, available actions). Lambda Cloud REST: GET /api/v1/instances/{id}.
```

### `lambda_list_audit_events`

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

Description, as the server wrote it:

```untrusted-server-text
List account audit-log events, optionally filtered by time window and resource type, with page_token pagination. Lambda Cloud REST: GET /api/v1/audit-events.
```

### `lambda_list_filesystems`

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

Description, as the server wrote it:

```untrusted-server-text
List your persistent filesystems (id, name, region, status, created_at) that can be attached to instances at launch. Lambda Cloud REST: GET /api/v1/file-systems.
```

### `lambda_list_firewall_rules`

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

Description, as the server wrote it:

```untrusted-server-text
List the account's inbound firewall rules (protocol, port range, source CIDR, description). Lambda Cloud REST: GET /api/v1/firewall-rules.
```

### `lambda_list_firewall_rulesets`

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

Description, as the server wrote it:

```untrusted-server-text
List firewall rulesets (id, name, region, rules) that can be applied to instances. Lambda Cloud REST: GET /api/v1/firewall-rulesets.
```

### `lambda_list_images`

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

Description, as the server wrote it:

```untrusted-server-text
List available machine images (id, name, family, version, region availability) that can be selected when launching an instance. Lambda Cloud REST: GET /api/v1/images.
```

### `lambda_list_instance_types`

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

Description, as the server wrote it:

```untrusted-server-text
List all GPU instance types with their specs (vcpus, memory, storage, gpus), hourly price (price_cents_per_hour), and which regions currently have capacity available. Use this to pick region_name + instance_type_name before launching. Lambda Cloud REST: GET /api/v1/instance-types.
```

### `lambda_list_instances`

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

Description, as the server wrote it:

```untrusted-server-text
List your running GPU cloud instances (id, name, ip, status, region, instance_type, ssh_key_names, filesystems, jupyter_url). Lambda Cloud REST: GET /api/v1/instances.
```
