AI agents call check_figma_dev_connection to retrieve information from Sunnyside Figma MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a diagnostic check of connection status between the MCP server and Figma's development API. It retrieves state information without modifying, executing, or destroying any data. Even if the check fails or succeeds, no resources are created, modified, or consumed. This is a typical Read category operation—a connectivity probe that returns status information.
From the tool's definition Tool name is 'check_figma_dev_connection' and appears designed to verify connectivity status ('check if Figma').
Documented attack patterns abuse exactly the kind of access check_figma_dev_connection gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sunnyside Figma MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for check_figma_dev_connection:
{
"version": "1",
"default": "deny",
"tools": {
"check_figma_dev_connection": {}
}
}check_figma_dev_connection is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Check if Figma. It is categorised as a Read tool in the Sunnyside Figma MCP MCP Server, which means it retrieves data without modifying state.
Register the Sunnyside Figma MCP server in PolicyLayer and add a rule for check_figma_dev_connection: 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 Sunnyside Figma MCP. Nothing to install.
check_figma_dev_connection is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the check_figma_dev_connection 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 check_figma_dev_connection. 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.
check_figma_dev_connection is provided by the Sunnyside Figma MCP server (tercumantanumut/sunnysidefigma-context-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
