DNS-only lookup. Returns all _mcp.{domain} TXT records — there can be multiple, each advertising a different MCP server. Fast, cheap, no HTTP calls. Supports single domain or batch lookup across multiple domains.

DNS lookup + server card in one call. Looks up all _mcp.{domain} TXT records, then fetches .well-known/mcp.json for server metadata. Only falls back to MCP initialize if no server card is found. Lighter than browse — no MCP session unless needed.

Inspect a domain or server URL. Tries .well-known/mcp.json (server card) first, only falls back to MCP initialize handshake if no server card is found. For domains: also performs DNS lookup for _mcp TXT records.

Call a tool on a remote MCP server. Use browse first to discover available tools, then use this to execute them.

Read a resource from a remote MCP server. Use browse first to see available resources, then use this to read one by its URI.

Get a prompt from a remote MCP server. Use browse first to see available prompts, then use this to retrieve one with optional arguments.

Generate client configuration to permanently register a discovered MCP server. Returns config file paths and JSON entries for Claude Desktop, VS Code, Cursor, and Windsurf. The agent should then read the target config file, merge the entry, and write it back. Accepts a server URL directly or a domain (runs discovery first).
