App Store Connect MCP Server

Instructions

Implementation Reference

• src/handlers/beta.ts:30-41 (handler)

  The main execution handler for the 'list_group_testers' tool. It validates input, sanitizes the limit parameter, and calls the AppStoreConnectClient to GET /betaGroups/{groupId}/betaTesters.

  async listGroupTesters(args: { 
    groupId: string; 
    limit?: number;
  }): Promise<ListBetaTestersResponse> {
    const { groupId, limit = 100 } = args;
    
    validateRequired(args, ['groupId']);
  
    return this.client.get<ListBetaTestersResponse>(`/betaGroups/${groupId}/betaTesters`, {
      limit: sanitizeLimit(limit)
    });
  }

• src/index.ts:150-168 (schema)

  Input schema definition for the tool, specifying required 'groupId' parameter and optional 'limit'.

    name: "list_group_testers",
    description: "Get a list of all testers in a specific beta group",
    inputSchema: {
      type: "object",
      properties: {
        groupId: {
          type: "string",
          description: "The ID of the beta group"
        },
        limit: {
          type: "number",
          description: "Maximum number of testers to return (default: 100)",
          minimum: 1,
          maximum: 200
        }
      },
      required: ["groupId"]
    }
  },

• src/index.ts:1326-1327 (registration)

  MCP tool registration in the CallToolRequest handler switch statement, mapping 'list_group_testers' to BetaHandlers.listGroupTesters method.

  return { toolResult: await this.betaHandlers.listGroupTesters(args as any) };

• src/types/beta.ts:30-32 (schema)

  TypeScript interface defining the expected response structure for the listGroupTesters handler.

  export interface ListBetaTestersResponse {
    data: BetaTester[];
  }
