set_multiple_annotations · Talk to Figma MCP: Risk & Policy

WHAT IT DOES

What set_multiple_annotations does on Talk to Figma MCP

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

WHY IT NEEDS A POLICY

Why set_multiple_annotations needs a policy

This tool modifies design metadata (annotations) in Figma but does not delete, execute arbitrary code, or trigger financial transactions. It is reversible—annotations can be edited or removed. While it affects design assets, the blast radius is limited to annotation metadata changes within a single or multiple nodes, making it a Write-category risk with medium severity.

From the tool's definition Tool name 'set_multiple_annotations' and description 'Set multiple annotations parallelly in a node' indicate creation or modification of annotations within a Figma design node. This is a reversible operation that adds or updates metadata/annotations.

Verdict

set_multiple_annotations Rate-limited

set_multiple_annotations 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_multiple_annotations

What does the set_multiple_annotations tool do? +

Set multiple annotations parallelly in a node. It is categorised as a Write tool in the Talk to Figma MCP 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_multiple_annotations? +

Register the Talk to Figma MCP server in PolicyLayer and add a rule for set_multiple_annotations: 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 Talk to Figma MCP. Nothing to install.

What risk level is set_multiple_annotations? +

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

Can I rate-limit set_multiple_annotations? +

Yes. Add a rate_limit block to the set_multiple_annotations 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_multiple_annotations completely? +

Set action: deny in the PolicyLayer policy for set_multiple_annotations. 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_multiple_annotations? +

set_multiple_annotations is provided by the Talk to Figma MCP server (pipethedev/talk-to-figma-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
