WHAT IT DOES

What update_permission_set does on Sanka MCP Server

AI agents use update_permission_set 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_permission_set is rated Medium

This tool modifies permission configurations that control who can access what resources in a workspace. While reversible (Write rather than Destructive), misuse could grant an AI agent excessive permissions, escalate privileges, or compromise workspace security. High severity due to the security-sensitive nature of permission management and potential blast radius across the workspace.

From the tool's definition Tool name 'update_permission_set' combined with description 'Update an existing Sanka permission set for workspace governance' indicates modification of access control settings.

RECOMMENDED RULE

The rule that runs update_permission_set 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_permission_set, this is the rule to start with:

update_permission_set Rate-limited

update_permission_set 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.
