microfn is a sandboxed cloud environment for building, deploying, and running tiny JavaScript functions, designed to be AI-friendly. It gives Claude its own workspace to write functions, deploy them, manage their code and secrets, and run the functions you've already built.
With microfn, Claude can:
- Write and deploy a new JavaScript function on request
- Inspect, update, and validate the code of existing functions
- Manage function settings and secrets
- Run your functions and use their results in the conversation
Each function runs in an isolated sandbox, so Claude can create and combine its own tools: fetch a weather API, keep data in a key-value store, post to Slack, or send a Telegram message.
Sign in with your microfn account over OAuth. The free plan includes 3 active functions and 100 executions per day, and Pro ($4.99/month) removes both limits.
