Browse Formstack forms, submissions and webhooks, search responses, and create submissions.
The publisher's own server: Ably MCP by usefulapi
Hosted Formstack connector that lets an assistant browse forms, folders and submissions, search responses, and create or update entries.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.usefulapi%2Fformstack/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}Use Formstack from Claude, Cursor, or any MCP client — browse forms, submissions and webhooks, search responses, and create or update submissions. Hosted, no local install: connect with your own Formstack credentials.
Live endpoint: https://formstack.usefulapi.io/mcp · Homepage: https://usefulapi.io/formstack
https://formstack.usefulapi.io/mcp.claude mcp add --transport http formstack https://formstack.usefulapi.io/mcp, then run /mcp to log in.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, and the login page asks for your Formstack credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/formstack/
On first connect you'll provide your Formstack Personal Access Token (account menu → API → Personal Access Tokens, starts with fs_pat_).
They're validated, stored per-user, and scoped to you — no keys in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
Each paid plan covers this server only. Ask your AI to run formstack_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with formstack_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with formstack_upgrade before then undoes the cancel. Or write to [email protected].

Permanently delete ONE submission and all associated data. First call with submission_id and its expected form_id to preview. Show the preview to the user and obtain their explicit confirmation, then call the SAME ids with confirm:true and the returned preview_token within 15 minutes. Changed records require a new preview. No bulk deletion, automatic replay or undo. A final read verifies absence; if unverified, inspect the submission before retrying. Formstack: GET, DELETE /submissions/{submissionId}.

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
