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.

Or run it on your computer

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

      ],
      "env": {
        "TLDERS_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add --transport http domain-prices https://www.tlders.com/api/mcp --header 'Authorization: your-value'

Common questions

Is TLDers Domain Prices 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: TLDERS_API_KEY, Authorization

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 41 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?

TLDers Domain Prices — MCP server

Live domain prices from 145+ registrars and 1,100+ TLDs, as a remote Model Context Protocol server. Ask your AI assistant where a domain is cheapest to register, renew or transfer, compare extensions, find promo codes and check availability — with real, daily-updated prices from TLDers.

Use it two ways: connect to the hosted server at https://www.tlders.com/api/mcp, or run this repository's small local (stdio) server, which forwards each tool call to the hosted one with your key.

Connect

Get a free API key at https://www.tlders.com/developers (no card needed).
Add a remote MCP server (Streamable HTTP):

Client	Setting
Clients that support headers (Claude Code, Cursor, VS Code, MCP Inspector)	URL `https://www.tlders.com/api/mcp`, header `Authorization: Bearer tld_live_...`
claude.ai custom connectors and other clients without header support	URL `https://www.tlders.com/api/mcp?key=tld_live_...`

Claude Code:

claude mcp add --transport http tlders https://www.tlders.com/api/mcp \

--header "Authorization: Bearer tld_live_..."

Treat a URL with ?key= like a password. If it leaks, revoke the key from your TLDers account and create a new one.

Local (stdio) server

For Claude Desktop's config file and other clients that run local servers. Needs Node.js 18+.

"mcpServers": { "tlders": { "command": "npx", "args": ["-y", "@tlders/mcp"], "env": { "TLDERS_API_KEY": "tld_live_..." } } } }

To run the server from source instead of the published package (useful while changing it), clone this repo, run npm install, then use "command": "node", "args": ["/path/to/tlders-mcp/index.js"]. It reads the same TLDERS_API_KEY variable, and TLDERS_MCP_URL overrides the hosted endpoint.

Plugin install

This repo is also an Agent Plugins package (plugin.json + mcp.json) that connects to the hosted server. Once installed, add your key by passing it as the api_key argument or switching the server URL to https://www.tlders.com/api/mcp?key=tld_live_....

Tools

Tool	What it does
`find_cheapest_tlds`	Cheapest registrar per extension for first-year registration, renewal, transfer and 3-year total
`get_tld_prices`	Every registrar's register / renew / transfer price for one extension, cheapest first
`compare_tlds`	Compare registrar prices across up to 20 extensions
`get_tld_price_history`	Per-registrar registration and renewal price history
`list_promo_codes`	Active registrar promo codes, biggest discount first
`check_domain_availability`	Live availability for a full domain name (RDAP, WHOIS fallback)
`list_registrars`	Every tracked registrar with WHOIS-privacy info

Prices are USD per year. First-year prices are often promotions, so the renewal price is always included.

All tools are read-only. Each one is annotated readOnlyHint: true, destructiveHint: false and idempotentHint: true. Nothing is bought, registered or changed, so clients can run them without asking for confirmation.

Example prompts

"Where is a .com cheapest to register and to renew?"
"Compare .io, .ai and .dev prices over three years."
"Is my-startup.dev available, and which registrar should I buy it from?"
"Are there any promo codes for .xyz right now?"

Plans

Plan	Limit
Free	100 requests a month, one key
Monthly ($5) / Yearly	1,000 requests a day per key, up to 5 keys, plus bulk prices
