Implementation Reference

• src/servers/danish-cvr.js:80-111 (handler)

  The tool "dk_cvr_search" is registered and implemented here. It takes a query, search_type, and country, processes the parameters, calls `fetchCVR`, and returns the formatted company data.

  server.tool(
    "dk_cvr_search",
    "Search the Danish CVR registry for a company by name, CVR number, P-number, or phone. Returns company details including address, industry, employees, owners, and status. Also supports Norwegian companies (country=no).",
    {
      query: z.string().describe("Company name, CVR number, P-number, or phone number to search for"),
      search_type: z.enum(["auto", "vat", "name", "produ", "phone"]).optional()
        .describe("Specific search type. 'auto' (default) searches all fields. 'vat' = CVR number, 'name' = company name, 'produ' = P-number, 'phone' = phone number"),
      country: z.enum(["dk", "no"]).optional()
        .describe("Country to search in. 'dk' = Denmark (default), 'no' = Norway"),
    },
    async ({ query, search_type, country }) => {
      const params = { country: country || "dk" };
  
      if (search_type && search_type !== "auto") {
        params[search_type] = query;
      } else {
        // Auto-detect: if all digits and 8 chars, likely CVR number
        if (/^\d{8}$/.test(query)) {
          params.vat = query;
        } else {
          params.search = query;
        }
      }
  
      try {
        const data = await fetchCVR(params);
        return { content: [{ type: "text", text: formatCompany(data) }] };
      } catch (err) {
        return { content: [{ type: "text", text: `Error: ${err.message}` }], isError: true };
      }
    }
  );
