Tool call template

This tool declares no required parameters. Add optional parameters from the input schema as needed.

{
  "id": 1,

  "params": {
    "arguments": {},
    "name": "pacer_stats"
  }
}

Implementation Reference

• src/tools/pacer.ts:178-209 (handler)

  The handler function for the pacer_stats tool. Calls the API endpoint /api/v1/pacer/stats, handles 404 (dataset not available) and other errors, and returns the stats JSON on success.

    async () => {
      const res = await apiGet<PacerStatsResponse>("/api/v1/pacer/stats");
  
      if (!res.ok) {
        if (res.status === 404) {
          return {
            content: [
              {
                type: "text" as const,
                text: "PACER dataset is not yet available. This data source is coming soon.",
              },
            ],
          };
        }
        return {
          content: [
            {
              type: "text" as const,
              text: `API error (${res.status}): ${JSON.stringify(res.data)}`,
            },
          ],
          isError: true,
        };
      }
  
      return {
        content: [
          { type: "text" as const, text: JSON.stringify(res.data, null, 2) },
        ],
      };
    },
  );

• src/tools/pacer.ts:22-27 (schema)

  The PacerStatsResponse interface defining the shape of the API response (dataset, source, update_frequency, stats).

  interface PacerStatsResponse {
    dataset: string;
    source: string;
    update_frequency: string;
    stats: Record<string, unknown>;
  }

• src/tools/pacer.ts:171-177 (schema)

  The input schema for pacer_stats — an empty object (no parameters required). Also includes title and description metadata.

  {
    title: "PACER Dataset Statistics",
    description:
      "Get statistics about the PACER court records dataset: total cases indexed, " +
      "courts covered, date range, and last updated timestamp. Free endpoint.",
    inputSchema: {},
  },

• src/tools/pacer.ts:169-209 (registration)

  The server.registerTool('pacer_stats', ...) call that registers the tool with the MCP server, binding the schema and handler.

  server.registerTool(
    "pacer_stats",
    {
      title: "PACER Dataset Statistics",
      description:
        "Get statistics about the PACER court records dataset: total cases indexed, " +
        "courts covered, date range, and last updated timestamp. Free endpoint.",
      inputSchema: {},
    },
    async () => {
      const res = await apiGet<PacerStatsResponse>("/api/v1/pacer/stats");
  
      if (!res.ok) {
        if (res.status === 404) {
          return {
            content: [
              {
                type: "text" as const,
                text: "PACER dataset is not yet available. This data source is coming soon.",
              },
            ],
          };
        }
        return {
          content: [
            {
              type: "text" as const,
              text: `API error (${res.status}): ${JSON.stringify(res.data)}`,
            },
          ],
          isError: true,
        };
      }
  
      return {
        content: [
          { type: "text" as const, text: JSON.stringify(res.data, null, 2) },
        ],
      };
    },
  );
