create_quest · DM20 Protocol MCP: Risk & Policy

WHAT IT DOES

What create_quest does on DM20 Protocol

AI agents use create_quest to create or update resources in DM20 Protocol — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DM20 Protocol environment.

WHY IT NEEDS A POLICY

Why create_quest needs a policy

The tool appears to create new quest records within a D&D campaign management system. This is a Write operation as it creates new data that can be modified or removed later in a campaign context. Severity is medium because misuse could clutter the campaign or create problematic quests, but impacts are reversible and limited to game state rather than external systems or permanent deletions.

From the tool's definition Tool name 'create_quest' indicates creation of new game data. Context from sibling tools (add_event, add_item_to_character, add_spell, add_session_note) shows this server performs reversible write operations on campaign state.

create_quest Rate-limited

create_quest 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.
