Generate comprehensive migration code for design token changes, including CSS updates, component modifications, and test cases.
AI agents use generate_migration_code to create or update resources in Sunnyside Figma MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sunnyside Figma MCP environment.
This tool creates new code artifacts (migration scripts, updated CSS, modified components, test cases) that alter the codebase. While reversible via version control, it modifies project files and could introduce bugs or breaking changes if misapplied. The impact depends on the AI agent's accuracy in applying the generated migration code to production systems.
From the tool's definition Tool generates code ('migration code', 'CSS updates', 'component modifications', 'test cases') that creates new files or modifies existing codebase assets. The description explicitly states it generates code output rather than merely reading or analyzing.
Documented attack patterns abuse exactly the kind of access generate_migration_code 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 generate_migration_code:
{
"version": "1",
"default": "deny",
"tools": {
"generate_migration_code": {
"limits": [
{
"counter": "generate_migration_code_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}generate_migration_code 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.

Generate comprehensive migration code for design token changes, including CSS updates, component modifications, and test cases. It is categorised as a Write tool in the Sunnyside Figma MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Sunnyside Figma MCP server in PolicyLayer and add a rule for generate_migration_code: 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.
generate_migration_code 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 generate_migration_code 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 generate_migration_code. 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.
generate_migration_code 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.
