RISK

Why vault_inject is rated Low

The name 'vault_inject' suggests interaction with a vault (likely credential/secret storage) and possibly injecting credentials or secrets into a browser session. Given the server context (AI-native browser with vault mentioned in server description), this likely involves writing or executing credential injection. However, with no description, the exact behavior is unknown.

From the tool's definition Tool name is 'vault_inject' but the description is empty or uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs vault_inject safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Looking Glass, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For vault_inject, this is the rule to start with:

vault_inject Rate-limited

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