create_chat · Sure MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_chat does on Sure MCP Server

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

WHY IT NEEDS A POLICY

Why create_chat needs a policy

The tool creates a new chat session, which is a write operation that generates new data in the system. It is reversible (sessions can be deleted as evidenced by the sibling delete_chat tool) and has no destructive, financial, or code execution properties. Low severity because creating a chat session poses minimal risk even if misused by an AI agent.

From the tool's definition Tool name 'create_chat' and description 'Create a new AI chat session' indicate creation of a new record/session without permanent deletion or financial impact. This is a write operation that creates reversible data.
