gsd_config_set · Gsd MCP: Risk & Policy

WHAT IT DOES

What gsd_config_set does on Gsd

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

WHY IT NEEDS A POLICY

Why gsd_config_set needs a policy

This tool modifies configuration state reversibly. While it could impact project behavior if misused (e.g., setting invalid parameters), it does not delete data (Destructive), move money (Financial), execute arbitrary code (Execute), or perform reads (Read).

From the tool's definition Tool name 'gsd_config_set' and description 'Write a GSD configuration value' directly indicate creation or modification of configuration data.
