check_domains — Check Domain Availability
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Check whether domain names are actually available to register, using live registry (RDAP) data. Use this when suggesting domain names (verify availability before presenting them, never assume a name is unregistered) or when the user asks whether specific domains are available. Accepts up to 50 fully-qualified domains (e.g. 'brewlog.app'). Returns availability, the registrar for taken domains, a 0-100 brandability score, an estimated resale value, the price in USD (price_usd for term_years, quote it rather than estimating; price_source 'checkout' is the expected charge at buy_url, confirmed before payment), and buy_url, the domhaul checkout page where the user can purchase the domain. If too few names are available, generate more candidates and call again.

get_tld_prices — Get TLD Registration Prices
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

Get registrar retail first-year price estimates in USD for top-level domains (.com, .io, .app, .dev, .ai, …). Use this when the user is comparing TLD options, e.g. 'should I get the .com or the .io?'. For the exact purchase price of a specific domain, use check_domains instead.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
