RISK

Why client_update is rated Medium

This tool creates or modifies client data reversibly without deletion. While it accesses personal information (moderate sensitivity), the constraint that 'Email cannot be changed via MCP' suggests appropriate safeguards are in place. The impact is limited to updating individual client records rather than bulk operations or irreversible destruction.

From the tool's definition Tool name 'client_update' and description 'Update an existing client's personal data' indicate modification of existing data records.

RECOMMENDED RULE

The rule that runs client_update safely

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

client_update Rate-limited

client_update stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
