Parameters from the server's own tool schema.
This tool queries and returns keys from a Redis database without modifying, deleting, or executing any code. It is purely informational/exploratory in nature, consistent with the Read category. Severity is low because the blast radius of listing keys is limited to information disclosure of key names, which may be sensitive but does not cause data modification or deletion.
From the tool's definition Tool name 'upstash_redis_list_keys' and description 'List keys in an Upstash Redis database matching a pattern' indicate a retrieval operation with no side effects.
