WHAT IT DOES

What gcp_kms_update_primary_version does on GCP MCP Server

AI agents use gcp_kms_update_primary_version to create or update resources in GCP MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your GCP MCP Server environment.

RISK

Why gcp_kms_update_primary_version is rated Medium

Updating the primary version of a crypto key is a reversible configuration change (the old version remains available and can be restored), so this falls under Write rather than Destructive.

From the tool's definition Tool name contains 'update' and description states 'Update the primary version of a crypto key'. This modifies cryptographic key configuration, affecting which key version is used for encryption/decryption operations going forward.

RECOMMENDED RULE

The rule that runs gcp_kms_update_primary_version safely
