What is mulerun-pool?

mulerun-pool is a Python tool that combines two related utilities into one codebase: automated bulk account registration for a service called MuleRun using Outlook email addresses, and an API key proxy pool for rotating multiple MuleRun API keys. The registration module, mulerun_register, uses a browser automation library to simulate the MuleRun sign up flow. You supply a CSV file containing Outlook email addresses and passwords, set your MuleRun invitation link, and the tool creates accounts in batch, optionally running headless, meaning without a visible browser window, or with a proxy server. It tracks each account's status in the CSV. The proxy pool module, mulerun_pool, is a FastAPI server that acts as a middleman between your applications and MuleRun's AI API. You give it a list of MuleRun API keys, and it exposes a local HTTP endpoint that is compatible with the OpenAI and Anthropic API formats, meaning tools that already know how to talk to OpenAI can be pointed at this proxy instead. When requests come in, the proxy rotates through the available keys, handles failures, and can be wired into API gateway tools like new-api or one-api. You would use this to manage a pool of MuleRun accounts and keys across multiple applications, centralizing key rotation and failure handling in one place. The tech stack is Python 3.11 or later, with FastAPI for the proxy server and Playwright, a browser automation library, for the registration flow.
