What can I ask?

Turn on the Kisi connector, then ask in plain words. The AI picks the tools.

Which doors are online, and which are currently locked down?
Who has access to the main office group?
Who came into the downtown office yesterday?
Which access cards are deactivated or unassigned?

What you can do with Kisi in Claude and ChatGPT

For office and facility managers and security admins who manage door access with Kisi.

Check which doors, controllers and readers are offline

The AI lists locks with online, locked-down and unlocked state, plus controllers and readers with online or offline status. You can find problem hardware fast.

See who has access to which doors

The AI lists access groups, the doors each group opens, the users in a group and role assignments. You can answer who can open a door or a place.

See who was present at a place on a day

The AI lists who was at a place on a given day, derived from unlocks, with first and last unlock and last door.

Check access cards and their status

The AI lists access cards with status (activated, deactivated or unassigned), assignee and last use. You can find cards that need cleanup.

Search the access log for unlocks and denied attempts

The AI searches the access log by event type, such as unlocks, denied attempts or lockdowns, and reads the result pages. This creates a temporary saved search in Kisi. No door or access right changes.

How do I connect Kisi?

Before you connect

The login page asks for your Kisi API key.

In the Kisi Dashboard click your name (top right) → My Account → API → Add API Key (organization admin or owner rights needed; the key is shown once). Your key is used only to call the Kisi API on your behalf; it is never shown to anyone.

Claude claude.ai · Desktop

Open Customize → Connectors, then click + Add → Add custom connector.
Enter the name Kisi and this URL, then click Add:
https://kisi.usefulapi.io/mcp
Claude opens the login page: enter your Kisi API key.
In a chat, click + → Connectors and turn on Kisi.

Team and Enterprise: an Owner adds the connector for the organization first.

ChatGPT chatgpt.com

Open Plugins, click +, then Add custom MCP server.
Enter the name Kisi and this URL, choose OAuth as the authentication, confirm the warning and create it:
https://kisi.usefulapi.io/mcp
ChatGPT opens the login page: enter your Kisi API key.
In Plugins, install Kisi, 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 kisi https://kisi.usefulapi.io/mcp

Cursor

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

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

VS Code

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

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

Codex

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

codex mcp add kisi --url https://kisi.usefulapi.io/mcp

codex mcp login kisi

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://kisi.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 Kisi 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.

Pricing

Plan	Price	Limit
Free	$0	50 tool calls / month
Proper user	$9/mo · $90/yr	10,000 tool calls / month
Pro+per user	$39/mo · $390/yr	100,000 tool calls / month

Each paid plan covers this Kisi server only. Ask your AI to run kisi_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 kisi_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 kisi_upgrade before then undoes the cancel. Or write to support@usefulapi.io.

Your usefulapi plan · 4

Usage status (free-tier meter)kisi_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 featurekisi_request_feature
Tell usefulapi that the user needs something the Kisi 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+kisi_upgrade
Get a paid plan for Kisi (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: call without confirm first, as the reply states the exact charge for this account (the price difference for the rest of the period, or in a free Pro trial the full Pro+ price, as the trial ends); then call with confirm: true. 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 subscriptionkisi_cancel_subscription
Cancel the caller's Kisi 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 kisi_upgrade later to undo the cancel before the period ends. Does not count against the meter.

FAQ

What can I do with Kisi in Claude or ChatGPT?

Check which doors, controllers and readers are offline. See who has access to which doors. See who was present at a place on a day. Check access cards and their status. Search the access log for unlocks and denied attempts. See what you can do for the details.

Is this an official Kisi product?

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

Can I connect Kisi 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 Kisi API key. See Before you connect for where to find it.

Do I put my Kisi 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 Kisi 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.

How do you keep my Kisi credentials?

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

Can the AI change my Kisi data?

Yes, if you approve it. 1 of the 20 Kisi tools can create or change data. The other 19 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 Kisi server only. Cancel any time: your paid plan then runs to the end of the paid period. Run kisi_usage_status to see how many calls you used.

How do I subscribe or cancel?

Ask the AI to run kisi_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 kisi_cancel_subscription. Your paid plan continues to the end of the paid period.

What if a Kisi tool that I need is missing?

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