Coding Agents

The Instant plugin installs the server together with skills and slash commands, so the agent knows when to search, when to verify a name, and how to read the results. It is an MCP pointer plus Markdown; nothing runs on your machine.

claude plugin marketplace add instant-labs/agent-plugins
claude plugin install instant@instant-marketplace

Start a new session afterwards so the agent loads the skills and tools.

What the plugin adds

instant
Skill. Which tool to call and the argument rules.
domain-brainstorm
Skill. Generate name ideas and check their domains in one pass.
/domain
Command. Check one name across extensions, or a list of full domain names.
/domain-variations
Command. Prefix and suffix alternatives for a name that is taken.

Claude Code prefixes the commands with the plugin name, as /instant:domain and /instant:domain-variations. The plugin is MIT licensed; read the source at instant-labs/agent-plugins.

Available Tools

search_domains
Check one name across extensions such as .com, .ai, and .dev. Provide the name without an extension.
generate_domain_variations
Find .com alternatives by adding common prefixes and suffixes to a name.
check_domain_availability
Check registration status for up to 50 full domain names in one request.
search_trademarks
Search indexed USPTO trademark records with exact, prefix, fuzzy, or phonetic matches. Filter by status, class, or owner, and return up to 100 matches.
get_trademark_details
Look up a trademark by its eight-digit USPTO serial number. Get its status, dates, owners, classes, goods and services, and filing flags. Trademark results include the snapshot freshness.

Domain results come from an index rebuilt daily. An uncovered extension can have unknown status. Each domain links to its research page on Instant Domain Search, with registrar prices and WHOIS details. Confirm availability with the registrar before purchase.

Try a Search

Once connected, ask your agent:

  • “Search for northstar across .com, .ai, and .dev.”
  • “Suggest .com alternatives to northstar with a prefix or suffix.”
  • “Check whether northstar.com and northstar.dev are registered.”
  • “Search USPTO trademarks for northstar, then show the details of a matching record.”
