AI agents use writeComponentsToFiles to create or update resources in MCP Figma to React Converter — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MCP Figma to React Converter environment.
This tool creates or modifies files on the filesystem by persisting generated React components. While not destructive (files can be overwritten or deleted), it irreversibly commits code artifacts to disk. Severity is high due to potential for writing malicious code, overwriting existing components, or polluting a codebase if an AI agent provides adversarial input to the upstream generation steps.
From the tool's definition Tool name 'writeComponentsToFiles' indicates writing/persisting generated React components to disk. Server context shows transformation of Figma designs into code files.
Documented attack patterns abuse exactly the kind of access writeComponentsToFiles gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Figma to React Converter, and nothing reaches the server without passing your rules. This is the rule we recommend for writeComponentsToFiles:
{
"version": "1",
"default": "deny",
"tools": {
"writeComponentsToFiles": {
"limits": [
{
"counter": "writecomponentstofiles_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}writeComponentsToFiles 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.

writeComponentsToFiles. It is categorised as a Write tool in the MCP Figma to React Converter MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the MCP Figma to React Converter MCP server in PolicyLayer and add a rule for writeComponentsToFiles: 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 to React Converter. Nothing to install.
writeComponentsToFiles 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 writeComponentsToFiles 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 writeComponentsToFiles. 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.
writeComponentsToFiles is provided by the MCP Figma to React Converter MCP server (studentofjs/mcp-figma-to-react). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
