How do I get an API key?
Log in to your Fillout.io account, go to Account Settings → API & Webhooks, click "Create new API Key", and copy the key. Production keys start with `fo_live_`, test keys with `fo_test_`.

The Fillout.io MCP Server is a Model Context Protocol server that integrates with the Fillout.io API to enable form management, response handling, and analytics. It is designed for developers and AI assistants to programmatically create, retrieve, and submit forms and responses.
Set up the server with Claude Desktop using either Docker or NPX configuration, providing your Fillout.io API key as the FILLOUT_API_KEY environment variable. Obtain an API key from your Fillout.io account settings; production keys start with fo_live_ and test keys with fo_test_. The server exposes tools such as list_forms, get_form, create_form, get_form_responses, and submit_form_response.
Log in to your Fillout.io account, go to Account Settings → API & Webhooks, click "Create new API Key", and copy the key. Production keys start with `fo_live_`, test keys with `fo_test_`.
"Invalid API key provided" or "Authentication failed" indicates the key is missing, malformed, or invalid. "Test mode key used with live form" occurs when using a test key on a production form. "Rate limit exceeded" means too many requests; implement request throttling and check usage in the dashboard.
Node.js 18 or later, and npm or yarn. Docker is optional for containerized deployment.
Data is stored on Fillout.io servers; the MCP server acts as a bridge and does not persist data locally.
Authentication is via a Fillout.io API key passed as the `FILLOUT_API_KEY` environment variable. Keep the key secure, use test keys for development, rotate keys periodically, and never commit keys to version control.
