WHAT IT DOES

What update_subscription does on Sanka MCP Server

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

RISK

Why update_subscription is rated Medium

This tool modifies existing subscription records, which is a Write operation. While subscriptions can have financial implications, the tool itself performs a data modification rather than moving money or creating financial obligations. The severity is medium because subscription updates could affect service continuity or billing, but the operation is reversible.

From the tool's definition Tool name 'update_subscription' and description 'Update an existing subscription in Sanka' indicate modification of subscription data.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_subscription safely

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

update_subscription Rate-limited

update_subscription 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.
