Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http lookuplab https://lookuplab.io/api/mcp --header 'X-API-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "lookuplab": {
      "url": "https://lookuplab.io/api/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "lookuplab": {
      "type": "http",
      "url": "https://lookuplab.io/api/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Common questions

Is LookupLab safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 26 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

LookupLab integrations

Phone carrier, email-domain, IP-network and DNS checks through LookupLab.

Find LookupLab on Smithery and in the official MCP Registry.

Claude web and Desktop

Open Customize > Connectors > Add custom connector. Name it LookupLab and use https://lookuplab.io/api/mcp.
Choose Sign in now and Register automatically if Claude shows authentication options. Leave a custom client ID and secret blank.
On LookupLab's consent page, enter your LookupLab key and approve. Enable the connector in your chat. Try: "Check the mail records for example.com."

Your key goes only to LookupLab; Claude receives a revocable OAuth connection. On Team and Enterprise plans, an owner first adds the connector, then each member connects their account. See Claude's connector setup.

Claude Code

Set LOOKUPLAB_API_KEY privately in your environment, then merge claude-code.mcp.json into your project's .mcp.json. Start Claude Code in that project, approve LookupLab when prompted, and check /mcp. Keep the variable reference in the file; never replace it with a real key in a shared repository.

The config uses Claude Code's HTTP transport and environment expansion. Try: "Check the mail records for example.com."

Gemini CLI

Install with gemini extensions install https://github.com/PpiNeaPpLe/lookuplab-integrations. Supply your existing LookupLab API key in the extension's sensitive setting. Gemini stores this setting in its system keychain when available. Never put a key in a chat message.

Other MCP clients

Connect to https://lookuplab.io/api/mcp with Authorization: Bearer YOUR_API_KEY or X-API-Key: YOUR_API_KEY in the client's secure connection settings. The server uses Streamable HTTP with JSON responses and no SSE stream.

ChatGPT and Codex

The openai/ directory is the portable plugin package. OAuth needs an exact callback registered by LookupLab before the platform connection can run. This source package is not a claim of directory approval or publication.

Tools and costs

Tool	Checks	Account credits
`phone_lookup`	Carrier, line type; optional caller name	1 for landline/VoIP/toll-free, 3 mobile/unknown; caller name adds 2
`email_verify`	Syntax, MX and domain indicators	1
`ip_lookup`	Approximate location and network	1
`dns_check`	MX, SPF, DMARC or DKIM	1

The account needs enough balance for the maximum charge before the lookup runs. Failed/invalid results are not charged. Tools debit credits, so they are marked as operations with side effects. Duplicate calls may charge again unless your client sends a stable Idempotency-Key header for retries.

Data is not proof of a person's identity, ownership, consent to contact, guaranteed email delivery or precise location. Privacy flags can be unavailable. Supply only data you are authorized to check.
