List forms, responses and uploaded files, and read text files in Formcrafts. For teams that collect responses through Formcrafts forms. Hosted by usefulapi — connect from Claude, ChatGPT, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"formcrafts": {
"url": "https://formcrafts.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"formcrafts": {
"type": "http",
"url": "https://formcrafts.usefulapi.io/mcp"
}
}
}No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
Run these commands. The second one opens the login page:
Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
List the forms of the organization, then list the responses of one form, filtered by date with the before and after parameters.
formcrafts_list_forms formcrafts_list_form_responses
Get one form, then list its partial responses. These are the answers that were started but not finished.
formcrafts_get_form formcrafts_list_form_responses
Get one form with its pages, fields, required flags and response count.
formcrafts_get_form
List the files uploaded through forms, then read the content of a text file, up to 200 KB.
formcrafts_list_files formcrafts_get_file_content
The login page asks for your Formcrafts API key.
Create the key in Formcrafts → Organization → Settings → API Keys. Your key is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Formcrafts API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Turn on the Formcrafts connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
formcrafts_list_workspaces | read | List workspaces List the workspaces in the Formcrafts organization (id, name, created_at). Good first call to find a workspace id for form lists. GET /v2/workspaces. |
formcrafts_list_forms | read | List forms List the forms in the organization: id, name, workspace_id, enabled, created_at and updated_at (last published). GET /v2/forms. |
formcrafts_get_form | read | Get form details Get one form: its fields (id, type, page, label, required), pages, enabled flag, response count and dates. GET /v2/forms/{id}. |
formcrafts_list_form_responses | read | List form responses List the live responses of one form: visitor data, the answers per field (field_id, value_type, value) and timestamps. Set partial=true to return only unfinished (partial) responses. GET /v2/forms/{id}/responses. |
formcrafts_list_files | read | List uploaded files List the files uploaded through forms in the organization: id, name, MIME type, size and dates. GET /v2/files. |
formcrafts_get_file_content | read | Get file content Get the content of one uploaded file. Text files (text/*, JSON, XML) return up to 200 KB of text. Other types return only their MIME type and size. GET /v2/files/{id}/content. |
formcrafts_usage_status | Usage status (free-tier meter) Report the caller's current usage: the plan, calls used this month, the limit of the plan (the free monthly cap or the Pro fair use limit), remaining, and whether the limit is reached. Read-only; does not count against the meter. | |
formcrafts_request_feature | Request a missing feature Tell usefulapi that the user needs something the Formcrafts tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
formcrafts_upgrade | Upgrade to Pro (unlimited*) Get Pro: unlimited tool calls (fair use limit: 10,000 a month) on Formcrafts (the free tier caps monthly usage). Plans: "monthly" — $9/month; "yearly" — $90/year (2 months free). Cancel any time: Pro then runs to the end of the paid period, so it also suits a one-time job. *A fair use limit applies. For heavy use (near Pro's limit): "plus" or "plus_yearly" — Pro+, $39/month or $390/year, unlimited tool calls (fair use limit: 100,000 a month); an existing Pro subscription changes to Pro+ in place (needs confirm: true; the price difference for the rest of the period is charged at once). Otherwise returns a short link to open in your browser (it opens Stripe Checkout); after payment the account upgrades automatically. Does not count against the meter. | |
formcrafts_cancel_subscription | Cancel the Pro subscription Cancel the caller's Formcrafts Pro subscription at the end of the paid period (no refund for the current period; Pro continues until then, then the free tier applies). Requires confirm: true. Run formcrafts_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Proper user | $9/mo · $90/yr | Unlimited* |
*Pro fair use limit: 10,000 tool calls a month on this server. For more, write to [email protected].
Pro covers this Formcrafts server only. Subscribe with formcrafts_upgrade (it returns a Stripe Checkout link). Cancel any time with formcrafts_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running formcrafts_upgrade before then undoes the cancel. Or write to [email protected].
See recent form responses. Find unfinished form responses. Review the fields of a form. Read a text file uploaded through a form. See what you can do for the details.
No. usefulapi is an independent service. It is not affiliated with or endorsed by Formcrafts. The server calls the Formcrafts API with your own Formcrafts access, so it sees only the data that your account can see.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
The login page asks for your Formcrafts API key. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Formcrafts API key. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Formcrafts API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Formcrafts.
All 6 Formcrafts tools are marked read-only.
The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls (fair use limit: 10,000 tool calls a month), for this Formcrafts server only. Cancel any time: Pro then runs to the end of the paid period. Run formcrafts_usage_status to see how many calls you used.
Ask the AI to run formcrafts_upgrade: it returns a Stripe Checkout link. To cancel, run formcrafts_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with formcrafts_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, ChatGPT, Codex, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
