Implementation Reference

• src/index.ts:423-436 (handler)

  The handler function that executes the tool logic: fetches market statistics from the EVE ESI API endpoint `/markets/${region_id}/stats/` using the makeESIRequest helper and returns a text content block with JSON-stringified stats.

  async ({ region_id }) => {
    const stats = await makeESIRequest<MarketStat[]>(
      `/markets/${region_id}/stats/`
    );
  
    return {
      content: [
        {
          type: "text",
          text: JSON.stringify(stats, null, 2)
        }
      ]
    };
  }

• src/index.ts:420-422 (schema)

  Zod input schema defining the required 'region_id' parameter for the tool.

  {
    region_id: z.number().describe("Region ID to get statistics from"),
  },

• src/index.ts:417-437 (registration)

  Registration of the 'get-market-stats' tool with server.tool(), including description, input schema, and inline handler.

  server.tool(
    "get-market-stats",
    "Get market statistics for a region",
    {
      region_id: z.number().describe("Region ID to get statistics from"),
    },
    async ({ region_id }) => {
      const stats = await makeESIRequest<MarketStat[]>(
        `/markets/${region_id}/stats/`
      );
  
      return {
        content: [
          {
            type: "text",
            text: JSON.stringify(stats, null, 2)
          }
        ]
      };
    }
  );

• src/index.ts:80-83 (schema)

  TypeScript interface defining the structure of individual market stat entries (name-value pairs) used for typing the API response in the handler.

  interface MarketStat {
    name: string;
    value: number;
  }
