kicad.export_svg · Eda MCP: Risk & Policy

WHAT IT DOES

What kicad.export_svg does on Eda

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

WHY IT NEEDS A POLICY

Why kicad.export_svg needs a policy

The tool exports design data to SVG format, which creates a new file artifact. This is a reversible write operation - the exported file can be deleted or regenerated without affecting the source design. While the description is empty (lowering confidence slightly), the naming convention and context of EDA workflows strongly suggest file generation/export functionality.

From the tool's definition Tool name 'export_svg' combined with sibling tools like 'add_component', 'add_wire', 'add_line' that are typical PCB design operations. Export functions typically write/generate output files.
