Generate self-contained TypeScript type declarations for specified schemas or for all schemas used by a specific endpoint. Endpoint mode follows supported internal component $refs before collecting schema dependencies. Provide exactly one of:
AI agents call get_types to retrieve information from Apifable without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and processes existing schema metadata from OpenAPI specifications to produce TypeScript type output. It performs pure data transformation and retrieval operations with no ability to modify API specs, execute arbitrary code, delete data, or trigger external operations. The generated types are artifacts consumed by developers, not actions executed against systems.
From the tool's definition Tool description states it "Generate[s]" TypeScript type declarations and "collect[s] schema dependencies" from OpenAPI specs. The verb "generate" here means derive/extract existing type information, not modify or execute code.
Documented attack patterns abuse exactly the kind of access get_types gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Apifable, and nothing reaches the server without passing your rules. This is the rule we recommend for get_types:
{
"version": "1",
"default": "deny",
"tools": {
"get_types": {}
}
}get_types is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Generate self-contained TypeScript type declarations for specified schemas or for all schemas used by a specific endpoint. Endpoint mode follows supported internal component $refs before collecting schema dependencies. Provide exactly one of:. It is categorised as a Read tool in the Apifable MCP Server, which means it retrieves data without modifying state.
Register the Apifable MCP server in PolicyLayer and add a rule for get_types: 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 Apifable. Nothing to install.
get_types 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 get_types 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 get_types. 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.
get_types is provided by the Apifable MCP server (ycs77/apifable). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Apifable, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
