create_service · Service Atlas MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_service does on Service Atlas MCP Server

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

WHY IT NEEDS A POLICY

Why create_service needs a policy

The tool creates new service records in a service dependency system. This is a Write category tool because it creates data without irreversibility. Severity is medium because creating invalid or malicious service entries could corrupt the dependency graph or cause operational confusion, but the action is reversible (services can be deleted or modified).

From the tool's definition Tool name 'create_service' indicates creation of a new service entity. Sibling tools like 'create_debt' and 'create_dependency' on the same server confirm this is a data creation tool.
