  The handleGetRecruitingStudies method implements the logic for the "get_recruiting_studies" tool, querying the ClinicalTrials.gov API for studies with "RECRUITING" status.

  private async handleGetRecruitingStudies(args: any) {
    const params: any = {
      format: "json",
      pageSize: args?.pageSize || 10,
      "filter.overallStatus": "RECRUITING",
    };
  
    if (args?.condition) {
      params["query.cond"] = args.condition;
    }
  
    if (args?.location) {
      params["query.locn"] = args.location;
    }
  
    if (args?.ageGroup) {
      params["filter.stdAge"] = args.ageGroup;
    }
  
    try {
      const response: AxiosResponse<StudySearchResponse> =
        await this.axiosInstance.get("/studies", { params });
  
      const studies = response.data.studies || [];
      const results = studies.map((study) => ({
