set_opacity

Set the opacity of one or more nodes (0 = fully transparent, 1 = fully opaque).

Part of the Figma Mcp Go MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.

// WHEN AI AGENTS USE THIS TOOL

AI agents use set_opacity to create or modify resources in Figma Mcp Go. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON SET_OPACITY

Without a policy, an AI agent could call set_opacity repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach Figma Mcp Go.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the set_opacity tool do? +

Set the opacity of one or more nodes (0 = fully transparent, 1 = fully opaque).. It is categorised as a Write tool in the Figma Mcp Go 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_opacity? +

Add a rule in your Intercept YAML policy under the tools section for set_opacity. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Figma Mcp Go MCP server.

What risk level is set_opacity? +

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

Can I rate-limit set_opacity? +

Yes. Add a rate_limit block to the set_opacity rule in your Intercept 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_opacity completely? +

Set action: deny in the Intercept policy for set_opacity. 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_opacity? +

set_opacity is provided by the Figma Mcp Go MCP server (@vkhanhqui/figma-mcp-go). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
