Implementation Reference

• src/index.ts:903-921 (handler)

  Handler function that sends a POST request to the external API endpoint `/api/v1/query-knowledge-base` using the DUMPLING_API_KEY for authentication, and returns the response as formatted JSON text.

  async ({ knowledgeBaseId, query, resultCount }) => {
    const apiKey = process.env.DUMPLING_API_KEY;
    if (!apiKey) throw new Error("DUMPLING_API_KEY not set");
    const response = await fetch(
      `${NWS_API_BASE}/api/v1/query-knowledge-base`,
      {
        method: "POST",
        headers: {
          "Content-Type": "application/json",
          Authorization: `Bearer ${apiKey}`,
        },
        body: JSON.stringify({ knowledgeBaseId, query, resultCount }),
      }
    );
    if (!response.ok)
      throw new Error(`Failed: ${response.status} ${await response.text()}`);
    const data = await response.json();
    return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] };
  }

• src/index.ts:898-902 (schema)

  Zod schema defining the input parameters: knowledgeBaseId (required string), query (required string), resultCount (optional number with default 5).

  {
    knowledgeBaseId: z.string().describe("Knowledge base ID"),
    query: z.string().describe("Search query"),
    resultCount: z.number().optional().default(5).describe("Number of results"),
  },

• src/index.ts:895-922 (registration)

  Registration of the 'search-knowledge-base' tool using server.tool(), including name, description, input schema, and inline handler function.

  server.tool(
    "search-knowledge-base",
    "Search a knowledge base for relevant information.",
    {
      knowledgeBaseId: z.string().describe("Knowledge base ID"),
      query: z.string().describe("Search query"),
      resultCount: z.number().optional().default(5).describe("Number of results"),
    },
    async ({ knowledgeBaseId, query, resultCount }) => {
      const apiKey = process.env.DUMPLING_API_KEY;
      if (!apiKey) throw new Error("DUMPLING_API_KEY not set");
      const response = await fetch(
        `${NWS_API_BASE}/api/v1/query-knowledge-base`,
        {
          method: "POST",
          headers: {
            "Content-Type": "application/json",
            Authorization: `Bearer ${apiKey}`,
          },
          body: JSON.stringify({ knowledgeBaseId, query, resultCount }),
        }
      );
      if (!response.ok)
        throw new Error(`Failed: ${response.status} ${await response.text()}`);
      const data = await response.json();
      return { content: [{ type: "text", text: JSON.stringify(data, null, 2) }] };
