reconstruct_page · Figmad MCP: Risk & Policy

WHAT IT DOES

What reconstruct_page does on Figmad

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

WHY IT NEEDS A POLICY

Why reconstruct_page needs a policy

This tool creates multiple Figma elements (frames, shapes, text) based on a previously captured DOM structure. It is a Write operation as it creates new design objects reversibly in Figma. The severity is high because it can generate a large number of elements in bulk, potentially affecting the entire Figma document structure, but it does not irreversibly destroy data.

From the tool's definition 'Reconstruct a captured webpage in Figma. Creates frames, shapes, and text based on the captured DOM structure.'

Verdict

reconstruct_page Rate-limited

reconstruct_page 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches Figmad, so you can run agents against it safely.

FAQ

Questions about reconstruct_page

What does the reconstruct_page tool do? +

Reconstruct a captured webpage in Figma. Creates frames, shapes, and text based on the captured DOM structure. Requires capture_webpage to be called first. It is categorised as a Write tool in the Figmad MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on reconstruct_page? +

Register the Figmad MCP server in PolicyLayer and add a rule for reconstruct_page: 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 Figmad. Nothing to install.

What risk level is reconstruct_page? +

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

Can I rate-limit reconstruct_page? +

Yes. Add a rate_limit block to the reconstruct_page 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 reconstruct_page completely? +

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

reconstruct_page is provided by the Figmad MCP server (toro1221/figmad-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
