MCP for Claude

The API has a built-in MCP endpoint that lets Claude Code interact with Namecheap using natural language.

Setup

Automatic (via CLI)

namecheap mcp install

This writes the MCP config to ~/.claude/settings.json. Restart Claude Code to activate.

Manual

claude mcp add --transport http namecheap https://api.namecheap.itz.tools/mcp \
  --header "x-api-key: sk-itzn_your-key"

How it works

The API exposes a Streamable HTTP MCP endpoint at /mcp. Claude Code connects to it using your API key. When you ask Claude to manage domains, it calls the MCP tools which hit the same API endpoints documented in this site.

Available tools

Tool	What it does
`check_domains`	Check if domains are available
`list_domains`	List all domains in your account
`get_domain`	Get domain details
`list_tlds`	List available TLDs
`renew_domain`	Renew a domain
`get_dns_records`	Get DNS records
`add_dns_record`	Add a DNS record (safe — preserves existing)
`remove_dns_record`	Remove a DNS record by hostId
`reset_dns_default`	Reset to Namecheap DNS
`get_nameservers`	Get nameservers
`set_nameservers`	Set custom nameservers
`get_balance`	Account balance
`get_pricing`	Domain pricing
`get_contacts`	WHOIS contacts
`get_lock_status`	Registrar lock status
`list_transfers`	List transfers
`list_whoisguard`	List privacy entries
`get_email_forwarding`	Email forwarding rules

Example conversation

“Check if coolstartup.io is available and if it is, show me the registration price”

Claude will call check_domains then get_pricing and give you the answer.

“Add an A record pointing @ to 1.2.3.4 on example.com”

Claude will call add_dns_record which safely reads existing records, appends yours, and writes them back.

Alternative: Claude Code skill

If you prefer CLI-based tool use over MCP:

namecheap skill install

This installs a /namecheap slash command that documents all CLI commands for Claude Code.
