create_vector · Figma MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_vector does on Figma MCP Server

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

WHY IT NEEDS A POLICY

Why create_vector needs a policy

This tool creates vector shapes/elements in Figma, which is a reversible modification operation. It fits the Write category (creates or modifies data reversibly). Severity is medium because misuse could clutter designs or interfere with user workflows, but changes can be undone in Figma. Confidence is 0.75 due to the empty description, though the naming pattern and sibling context strongly suggest vector creation.

From the tool's definition Tool name 'create_vector' combined with sibling tools like 'create_arc', 'create_circle', 'create_frame_in_figma', 'create_line', 'create_polygon' which clearly perform creation operations in Figma. The tool description is empty, reducing certainty.

Verdict

create_vector Rate-limited

create_vector stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
