Add Fillio to Claude, ChatGPT, Cursor, or any MCP-compatible tool. Describe what you need, get back a shareable form.
https://fillio.so/api/mcpOpen your AI tool's connector settings and add the Fillio MCP server using the URL above.
Start a new chat, enable the Fillio connector, and ask for what you need in plain language. The AI picks the fields, logic, and language.
Open the claim link, sign in on fillio.so, and the form is yours to edit, share, embed, or analyze.
“Post-visit feedback survey for a restaurant with 5 questions, a star rating, and a comment box.”
“RSVP form that asks for guest count, dietary needs, and a song request.”
“Remote frontend developer application with a resume upload and three short-answer questions.”
The connector exposes exactly one tool. No other capability is registered.
create_formCreate formCreates a new form on Fillio from a natural-language description and returns a one-time claim link the user opens to take ownership of it.
| Name | Type | Description |
|---|---|---|
| description* | string | Plain-language description of the form to build. Max 2000 characters. The generator picks the question types, options, ordering, and validation from this text. |
| language | string | ISO 639-1 code for the form content (e.g. "en", "tr", "es"). Omit it and the language is inferred from the description. |
A single text block containing the form title and the claim URL in the shape https://fillio.so/r/{formId}?claimToken={token}. On failure the same text block carries the reason and isError is set.
Only the two tool arguments: your form description and an optional language code. The connector does not read your chat history, and it requests no account, token, or credential to run.
The generated form (questions, options, pages, settings), the description used to generate it, the creation timestamp, and a single-use claim token. The form is marked as created through the Claude connector so you can recognise it later.
A new form has no owner. The claim link transfers it to whichever Fillio account is signed in when the link is opened, and the token is spent at that moment. Until it is claimed, anyone holding the link can claim the form, so treat it as a secret and claim it promptly.
The connector never reads form responses. Submissions are visible only in the Fillio account that claimed the form, through the normal dashboard.
Claim the form, then delete it from its settings page. That removes the form and every response with it. If you never claim a form and want it gone, contact us through the support page and we will remove it.

An MCP (Model Context Protocol) server that lets AI chat tools create Fillio forms on your behalf. You describe the form in plain language, the tool calls Fillio, and you get back a ready-to-share form.
Any tool that supports the Model Context Protocol. Tested in Claude, ChatGPT, Cursor, and Windsurf. Other MCP-compatible clients follow the same pattern.
No. Your first form comes with a one-time claim link. Open it, sign in on fillio.so, and the form is transferred to your account so you can edit, share, and collect responses.
In Claude, open Settings → Connectors → Add custom connector. Paste https://fillio.so/api/mcp and save. In a new chat, enable the Fillio connector and ask for any form.
Yes. Creating forms through the MCP connector is free. Advanced limits like response volume and CSV export depend on your Fillio plan. See fillio.so/pricing for details.
