RISK

Why vault_login is rated Low

The name suggests authentication/login to a vault system, which could involve reading credentials, writing session tokens, or executing an auth flow. However, with no description available, it's unclear whether it reads, writes, or executes. Given the 'vault' context (likely credential storage) and 'login' action, it most plausibly initiates an authentication session (Write-level at most), but confidence is low.

From the tool's definition Tool name is 'vault_login'; description is empty or uninformative.

vault_login gets a rate cap, and everything else on the server is denied unless you say otherwise.
