Description: Tools that enable LLMs to interact directly with the engine API.
Author: Arcade
Auth: API Key
EngineApi is a Starter MCP Server: each tool mirrors one HTTP endpoint and offers LLMs a way to interact with the low-level API.
Differently from Optimized MCP Servers, Starter tools are heavily influenced by the original API design, which is not usually optimized for LLM usage. For this reason, we recommend thoroughly evaluating the tools with your Agents or chatbots before using it in production. Read more about Optimized vs Starter tools.
The EngineApi Server offers a comprehensive suite of for managing authentication providers, secrets, and worker configurations. and LLMs can perform a variety of actions, including:
