Implementation Reference

  • The handler function for the `pm_micro_changes` tool which calls the API and processes the response.
      async ({ since, limit }) => {
        const res = await apiGet<PmMicroQueryResponse>("/api/v1/pm/micro/changes", {
          since,
          limit: limit ?? 50,
        });
    
        if (!res.ok) {
          return {
            content: [
              {
                type: "text" as const,
                text: `API error (${res.status}): ${JSON.stringify(res.data)}`,
              },
            ],
            isError: true,
          };
        }
    
        const { count, data } = res.data;
        const warn = stalenessWarning(res);
        const summary = `${warn}Found ${count} microstructure change(s) since ${since}.`;
        const json = JSON.stringify(data, null, 2);
    
        return {
          content: [{ type: "text" as const, text: `${summary}\n\n${json}` }],
        };
      },
    );
