Which app do you use?

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 domain-intelligence https://oti-labs.com/mcp --header 'X-RapidAPI-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": {
    "domain-intelligence": {
      "url": "https://oti-labs.com/mcp",
      "headers": {
        "X-RapidAPI-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

Your choice stays on this device in a cookie; no account needed.

Values you fill in

X-RapidAPI-Key secret HTTP header
Optional. Without a key: 1,000 free lookups a month per IP. With a RapidAPI key subscribed to the Domain Intelligence API: your plan's quota (free plan: another 1,000 a month).

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Domain Intelligence safe?

It passed 0 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-RapidAPI-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 (1.1.0) reached the registry 35 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?

Domain Intelligence MCP server

An MCP server that gives AI agents and assistants WHOIS/RDAP, DNS, SSL, subdomain and email-security lookups for any domain.

Hosted endpoint: https://oti-labs.com/mcp (Streamable HTTP)
Registry name: com.oti-labs/domain-intelligence (also on Smithery)
No key to start: 1,000 lookups a month per IP (per /64 for IPv6), up to 10 a minute. Hosted connectors that call from their provider's shared addresses (Claude, ChatGPT, the Smithery gateway) share one pool per provider: 10,000 a month, up to 120 a minute. Keyless use on the hosted server stops at 2,000 calls a day in total and resets at 00:00 UTC.
After that: add a RapidAPI key in the X-RapidAPI-Key header (or Authorization: Bearer ). Calls then count on your RapidAPI plan; the free plan adds another 1,000 a month: get a key.

Tools

Tool	What it returns
`domain_lookup`	Everything below in one call. Big subdomain lists are trimmed (`subdomain_limit`, default 50).
`whois_lookup`	Registrar, created/updated/expiry dates, nameservers, status. RDAP first, port-43 WHOIS fallback.
`dns_records`	A, AAAA, MX, TXT, NS, CAA and SOA records.
`ssl_certificate`	Live TLS handshake: issuer, validity dates, `days_until_expiry`, SANs, signature algorithm.
`subdomains`	Live hosts with IPs, all names found (live first), collapsed infrastructure pools. `wait=true` waits for every source.
`email_security`	SPF, DMARC, and DKIM keys from ~29 common selectors.

All tools are read-only.

Setup

These work without a key. To use a RapidAPI key, add the header shown at the end of this section.

Claude Code

claude mcp add --transport http domain-intelligence https://oti-labs.com/mcp

Cursor (~/.cursor/mcp.json)

"mcpServers": { "domain-intelligence": { "url": "https://oti-labs.com/mcp" } } }

VS Code (.vscode/mcp.json)

"servers": { "domain-intelligence": { "type": "http", "url": "https://oti-labs.com/mcp" } } }

Windsurf (~/.codeium/windsurf/mcp_config.json)

"mcpServers": { "domain-intelligence": { "serverUrl": "https://oti-labs.com/mcp" } } }

Claude Desktop and other stdio-only clients, through mcp-remote:

"mcpServers": { "domain-intelligence": { "command": "npx", "args": ["-y", "mcp-remote", "https://oti-labs.com/mcp"] } } }

Adding a RapidAPI key. Claude Code: append --header "X-RapidAPI-Key: YOUR_KEY". Cursor, VS Code and Windsurf: add "headers": { "X-RapidAPI-Key": "YOUR_KEY" } next to the URL. mcp-remote: add "--header", "X-RapidAPI-Key:YOUR_KEY" to args.

Example prompts

"How old is example.com and who is the registrar?"
"Is this domain suspicious? Check its age, SSL issuer and SPF/DMARC."
"List the live subdomains of example.com with their IPs."
"When do the SSL certificates for these 10 domains expire?"

Self-hosting

The server is one file. Keyed calls go through RapidAPI with the caller's key; keyless calls go to DI_INTERNAL_BASE with RAPIDAPI_PROXY_SECRET and are counted in Redis (REDIS_URL):

pip install -r requirements.txt

uvicorn server:app --host 127.0.0.1 --port 8002

To send keyed calls to your own copy of the API instead of RapidAPI, set DI_API_BASE (and DI_PROXY_SECRET if your API checks one).

Keyless limits can be changed with MCP_KEYLESS_MONTHLY, MCP_KEYLESS_PER_MINUTE, MCP_PROVIDER_MONTHLY, MCP_PROVIDER_PER_MINUTE and MCP_KEYLESS_DAILY_CEILING. ChatGPT's connector addresses come from chatgpt-connectors.json, which refresh_openai_ranges.py downloads from OpenAI; run it once a day from cron. Without that file, ChatGPT calls are counted per IP. Claude's outbound range is built in.
