set_active_board · Framedeck MCP: Risk & Policy

WHAT IT DOES

What set_active_board does on Framedeck

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

WHY IT NEEDS A POLICY

Why set_active_board needs a policy

This tool modifies application configuration state (the active board context) rather than data itself, making it a Write operation. The severity is low because changing context is reversible and has no direct impact on content, production data, or external systems—it merely affects which board subsequent operations target by default.

From the tool's definition Tool description states it will 'Set the active board/production context' and change what 'other tools will use...by default', indicating modification of application state/context.

set_active_board Rate-limited

set_active_board 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.
