csmar_list_tables

Instructions

Implementation Reference

• src/index.js:448-462 (handler)

  The MCP tool handler for 'csmar_list_tables'. It ensures login, then calls the Python client via client.call('list_tables', { database_name }) and returns the result as JSON text.

      async ({ database_name }) => {
          try {
              const loginResult = await ensureLogin();
              if (!loginResult.success) {
                  return { content: [{ type: 'text', text: JSON.stringify(loginResult, null, 2) }], isError: true };
              }
              
              const client = await initPythonClient();
              const result = await client.call('list_tables', { database_name });
              return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }] };
          } catch (error) {
              return { content: [{ type: 'text', text: `获取表列表错误: ${error.message}` }], isError: true };
          }
      }
  );

• src/index.js:442-447 (schema)

  Input schema definition for the csmar_list_tables tool: requires a 'database_name' string parameter.

  {
      description: '列出指定数据库中的所有表',
      inputSchema: {
          database_name: z.string().describe('数据库名称'),
      },
  },

• src/index.js:440-462 (registration)

  Registration of the tool 'csmar_list_tables' via server.registerTool with its description, inputSchema, and handler.

  server.registerTool(
      'csmar_list_tables',
      {
          description: '列出指定数据库中的所有表',
          inputSchema: {
              database_name: z.string().describe('数据库名称'),
          },
      },
      async ({ database_name }) => {
          try {
              const loginResult = await ensureLogin();
              if (!loginResult.success) {
                  return { content: [{ type: 'text', text: JSON.stringify(loginResult, null, 2) }], isError: true };
              }
              
              const client = await initPythonClient();
              const result = await client.call('list_tables', { database_name });
              return { content: [{ type: 'text', text: JSON.stringify(result, null, 2) }] };
          } catch (error) {
              return { content: [{ type: 'text', text: `获取表列表错误: ${error.message}` }], isError: true };
          }
      }
  );

• src/python_client.py:244-253 (handler)

  The Python-side handler (get_list_tables) that calls the CSMAR SDK's getListTables() for the given database_name and returns the table list.

  def get_list_tables(self, database_name: str) -> Dict[str, Any]:
      try:
          csmar = self._ensure_csmar()
          tables = csmar.getListTables(database_name)
          if tables is None:
              return {"success": False, "error": f"表列表为空 (数据库: {database_name})", "tables": [], "count": 0}
          table_list = list(tables) if hasattr(tables, '__iter__') else [str(tables)]
          return {"success": True, "database": database_name, "tables": table_list, "count": len(table_list)}
      except Exception as e:
          return {"success": False, "error": f"获取表列表失败: {str(e)}"}

• src/python_client.py:309-318 (helper)

  Command dispatcher that routes the 'list_tables' action to CSMARClient.get_list_tables() with the database_name parameter.

  def handle_command(command: Dict[str, Any], client: CSMARClient) -> Dict[str, Any]:
      action = command.get("action")
      params = command.get("params", {})
  
      handlers = {
          "login": lambda: client.login(
              params.get("account", ""), params.get("pwd", ""), params.get("lang", "0")
          ),
          "list_databases": lambda: client.get_list_dbs(),
          "list_tables": lambda: client.get_list_tables(params.get("database_name", "")),
