Set the text case of a text node in Figma
AI agents use set_text_case to create or update resources in Claude Talk to Figma MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Claude Talk to Figma MCP environment.
This tool modifies design content by changing text formatting properties, which qualifies as a Write operation. It is reversible (the original case can be restored), so it does not rise to Destructive. Severity is medium because unintended bulk application could degrade design quality or require manual correction, but the blast radius is limited to text case formatting within Figma documents.
From the tool's definition Tool name 'set_text_case' and description 'Set the text case of a text node in Figma' indicate modification of text properties within a design document. This is a reversible operation that changes node attributes.
Documented attack patterns abuse exactly the kind of access set_text_case gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Claude Talk to Figma MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for set_text_case:
{
"version": "1",
"default": "deny",
"tools": {
"set_text_case": {
"limits": [
{
"counter": "set_text_case_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} set_text_case 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.

Set the text case of a text node in Figma. It is categorised as a Write tool in the Claude Talk to Figma MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Claude Talk to Figma MCP server in PolicyLayer and add a rule for set_text_case: 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 Claude Talk to Figma MCP. Nothing to install.
set_text_case is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the set_text_case 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.
Set action: deny in the PolicyLayer policy for set_text_case. 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.
set_text_case is provided by the Claude Talk to Figma MCP server (arinspunk/claude-talk-to-figma-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Claude Talk to Figma MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
