What you can do with Stiply in Claude and ChatGPT

For teams that send documents for e-signing with Stiply.

See which documents still wait for a signature

List sign requests and filter by status, such as published or rejected. Open one to read its message, dates and reject reason.

Check who has not signed yet

Open a sign request and list its signers with their role. Read the progress trail to see who opened the mail and who signed.

Find a sign request by the key of your own system

Look up a sign request with the external key that your system stored. Then list the documents attached to it.

Remind the signers of an open request

Find the open sign request. Send a reminder by email to the signers who have not signed. Extend the term if the date is close.

Changes data

Send a new document for signature

Create a sign request from PDF links and send it to the signers. Confirm the signers first, because Stiply emails them at once.

How do I connect Stiply?

Before you connect

The login page asks for your Stiply Personal Access Token.

Create it in Stiply → Settings → API (app.stiply.nl/settings/api). Your token is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.

Claude claude.ai · Desktop

  1. Open Customize → Connectors, then click + Add → Add custom connector.
  2. Enter the name Stiply and this URL, then click Add:
    https://stiply.usefulapi.io/mcp
  3. Claude opens the login page: enter your Stiply Personal Access Token.
  4. In a chat, click + → Connectors and turn on Stiply.

  2. Enter the name Stiply and this URL, choose OAuth as the authentication, confirm the warning and create it:
    https://stiply.usefulapi.io/mcp
  3. ChatGPT opens the login page: enter your Stiply Personal Access Token.
  4. In Plugins, install Stiply, then choose it in a chat.

No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.

Claude Code

Run this command, then run /mcp in Claude Code to log in:

claude mcp add --transport http stiply https://stiply.usefulapi.io/mcp

Cursor

Add to Cursor or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "stiply": {
      "url": "https://stiply.usefulapi.io/mcp"
    }
  }
}

VS Code

Add to VS Code or add this to .vscode/mcp.json:

{
  "servers": {
    "stiply": {
      "type": "http",
      "url": "https://stiply.usefulapi.io/mcp"
    }
  }
}

Codex

Run these commands. The second one opens the login page:

codex mcp add stiply --url https://stiply.usefulapi.io/mcp
codex mcp login stiply

Other clients

Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.

https://stiply.usefulapi.io/mcp

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 Stiply Personal Access Token. 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.

Free$050 tool calls / month
Proper user$9/mo · $90/yr10,000 tool calls / month

Each paid plan covers this Stiply server only. Ask your AI to run stiply_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 stiply_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 stiply_upgrade before then undoes the cancel. Or write to [email protected].

Your usefulapi plan · 4

  • Usage status (free-tier meter)stiply_usage_status
    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.
  • Request a missing featurestiply_request_feature
    Tell usefulapi that the user needs something the Stiply 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.
  • Upgrade to Pro or Pro+stiply_upgrade
    Get a paid plan for Stiply (the free tier caps monthly usage). Pro: 10,000 tool calls a month, for normal use — plan "monthly" ($9/month) or "yearly" ($90/year, 2 months free). Pro+: 100,000 tool calls a month, for automations and heavy use — plan "plus" ($39/month) or "plus_yearly" ($390/year). Without a plan it returns both Pro and Pro+, each with a payment link, for the user to choose; with a plan, one link. 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). Cancel any time: the plan then runs to the end of the paid period, so it also suits a one-time job. A link opens Stripe Checkout in the browser; after payment the account upgrades automatically. Does not count against the meter.
  • Cancel the Pro subscriptionstiply_cancel_subscription
    Cancel the caller's Stiply 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 stiply_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Stiply in Claude or ChatGPT?

See which documents still wait for a signature. Check who has not signed yet. Find a sign request by the key of your own system. Remind the signers of an open request. Send a new document for signature. See what you can do for the details.

Is this an official Stiply product?

No. usefulapi is an independent service. It is not affiliated with or endorsed by Stiply. The server calls the Stiply API with your own Stiply access, so it sees only the data that your account can see.

Can I connect Stiply to Claude or ChatGPT?

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.

What do I need to connect?

The login page asks for your Stiply Personal Access Token. See Before you connect for where to find it.

Do I put my Stiply key or an Authorization header in the client config?

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 Stiply Personal Access Token. 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.

How do you keep my Stiply credentials?

The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Stiply 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 Stiply.

Can the AI change my Stiply data?

Yes, if you approve it. 4 of the 10 Stiply tools can create or change data. The other 6 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.

What does it cost?

The Free plan gives 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Stiply server only. Cancel any time: your paid plan then runs to the end of the paid period. Run stiply_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run stiply_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+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run stiply_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Stiply tool that I need is missing?

Tell the AI what you wanted to do. It can send the request with stiply_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.

Which AI clients can I use?

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.
