WHAT IT DOES

What generate_component_spec does on AI-Canvas MCP Server

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

WHY IT NEEDS A POLICY

Why generate_component_spec needs a policy

This tool creates a new technical specification document (a design artifact), which is a reversible write operation. It does not execute arbitrary code, delete content, or move money. While it modifies the design canvas state by generating new content, this is consistent with a Write classification.

From the tool's definition Tool description states 'Generate a technical specification' which creates/produces new design specification content.
