create_connections · MCP Figma MCP: Risk & Policy

WHAT IT DOES

What create_connections does on MCP Figma

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

WHY IT NEEDS A POLICY

Why create_connections needs a policy

This tool creates new connections between design nodes, which is a reversible modification to the Figma document. It does not execute arbitrary code, delete data, or move money. The severity is medium because misuse could create unwanted design changes requiring manual cleanup, but the changes are non-destructive and can be undone in Figma.

From the tool's definition Tool name 'create_connections' and description 'Create connections between nodes using the default connector style' indicate creation of new design elements (connections/connectors) in Figma, which modifies the design file.

create_connections Rate-limited

create_connections 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.
