Overview

AI-generated overview

Lets an assistant read Fillout forms and submissions, export responses, and create submissions and webhooks through a hosted endpoint.

What it does
Connects to a hosted Fillout MCP endpoint that exposes read tools for listing forms, getting form questions and metadata, listing, getting, counting and exporting submissions, plus write tools for creating submissions and creating or removing submission webhooks. Two meta tools report usage status and manage a Pro upgrade. It runs remotely, so no local install is needed.
When to use it
Useful when you work with Fillout forms and want an assistant to inspect form structure, review or export responses, or programmatically add submissions and webhooks without leaving the chat client. It fits teams already using Fillout who want conversational access to their form data.
Requirements
A remote MCP client pointed at the hosted endpoint. You must supply your own Fillout API key (from Settings, Developer) and your data region (US or EU) on first connect; credentials are validated and stored per user rather than in config files. Network access to the endpoint is required.
Before you install
The server asks for your Fillout API key, a credential that grants access to your forms and submissions. Write tools create submissions and create or remove webhooks, which change data and should be confirmed before running. The free tier is limited to 100 tool calls per month, and a paid Pro plan is offered through a meta tool.

Fillout MCP by usefulapi

Use Fillout from Claude, Cursor, or any MCP client — read forms and their questions, list, count and export submissions, and create submissions and webhooks. Hosted, no local install: connect with your own Fillout credentials.
