set_axis_align · MCP Figma MCP: Risk & Policy

WHAT IT DOES

What set_axis_align does on MCP Figma

AI agents use set_axis_align 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 set_axis_align needs a policy

The tool modifies design metadata (axis alignment settings) within a Figma frame, which is a Write operation as it changes existing data reversibly. The severity is medium because misuse could disrupt design layouts affecting multiple team members viewing the file, but changes can be undone and do not delete data or execute arbitrary code. Confidence is high given the clear, descriptive function name and purpose.

From the tool's definition Tool description states 'Set primary and counter axis alignment for an auto-layout frame in Figma', which modifies design properties. This is a reversible configuration change to a frame's layout settings, not destructive deletion or code execution.

Verdict

set_axis_align Rate-limited

set_axis_align 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.

FAQ

Questions about set_axis_align

What does the set_axis_align tool do? +

Set primary and counter axis alignment for an auto-layout frame in Figma. It is categorised as a Write tool in the MCP Figma MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on set_axis_align? +

Register the MCP Figma MCP server in PolicyLayer and add a rule for set_axis_align: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Figma. Nothing to install.

What risk level is set_axis_align? +

set_axis_align is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit set_axis_align? +

Yes. Add a rate_limit block to the set_axis_align rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block set_axis_align completely? +

Set action: deny in the PolicyLayer policy for set_axis_align. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides set_axis_align? +

set_axis_align is provided by the MCP Figma MCP server (yelowflash09/figma_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
