add_project · MCP Project Query Server MCP: Risk & Policy

WHAT IT DOES

What add_project does on MCP Project Query Server

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

WHY IT NEEDS A POLICY

Why add_project needs a policy

This tool creates new projects, which is a reversible write operation. It modifies application state by adding data to a project store but does not delete, execute arbitrary code, or move financial resources. Severity is medium rather than low because mass project creation could degrade system performance or consume resources, though the impact is bounded to the application's project management scope.

From the tool's definition Tool name 'add_project' combined with description '新增项目' (which translates to 'add project' in English). The server description indicates it 'supports project queries, creation' explicitly confirming write capability.
