# UserCheck integrations

Connect UserCheck to any other app, or use it from your AI client over MCP. UserCheck is a service that validates email addresses and domains to detect disposable and temporary email providers.

Connects with an API key [usercheck.com](https://usercheck.com/)

**3** actions

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want to automate with UserCheck?

Give your AI client this address.

`https://mcp.apiant.ai`

One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

### Cursor

Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

### Zed

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

### Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

## What our customers say

Questions

## UserCheck, answered

###

### Is there a UserCheck MCP server?

APIANT's MCP server at https://mcp.apiant.ai works with UserCheck. Add that address to any AI client that takes a remote MCP server and sign in once in your browser. Your client can then run UserCheck actions on demand, or have APIANT build, test and run automations that use UserCheck. Nothing to install.

###

### What can your agent do in UserCheck?

Any of UserCheck's 3 actions, including Check Domain, Check Email and Get account status. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can I use UserCheck directly from Claude, ChatGPT or Cursor?

Yes. Connect your AI client to APIANT once and it works with UserCheck two ways. Ask it to do something in UserCheck once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running on its own. A one-off action uses your plan's tasks the same way an automation step does.

###

### Do I need to write code against the UserCheck API?

No. APIANT connects to the UserCheck API for you, with your UserCheck API key. Describe what you want in plain language and your agent builds it on the UserCheck triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the UserCheck API documentation and adds it.

###

### Which apps can UserCheck connect to?

Any app in the catalog; the list on this page pairs UserCheck with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector.

###

### What happens when something fails?

Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.

###

### Is there a free plan?

Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
