连接故障排除

Diagnose and fix Delegate connection, authentication, and MCP server issues: failed connections, missing scopes, and unreachable or misconfigured MCP servers.

连接失败或身份验证错误

Cause: The connection expired or was revoked.

Solution: Reconnect from Add-ons & Integrations → Connections.

If reconnecting doesn't fix it:

1. 断开连接，然后重新创建连接。
2. 请检查服务自身的第三方应用程序设置。

“未找到 的连接”<service>

Cause: The service isn't connected yet.

解决方案：

• 从加载项和集成→连接中创建连接。
• 或者采用不需要它的方法。

Delegate can't perform certain operations

Cause 1: The connection was created with narrower scopes than the action needs.
Solution 1: Disconnect and reconnect from Add-ons & Integrations → Connections, granting the additional scopes when prompted.

Cause 2: An organization policy restricts scopes.
Solution 2: Check with your administrator.

无法连接 MCP 服务器

Cause 1: The server is down or unreachable.
Solution 1: Confirm it's running (local) or reachable (remote).

Cause 2: The URL or command has a typo.
Solution 2:

1. 检查 URL。
2. 直接测试端点。

Cause 3: A firewall is blocking it.
Solution 3:

1. 检查防火墙设置。
2. 查看本地流程日志以获取启动错误。

MCP 服务器已连接，但没有可用工具

Cause: It hasn't registered any tools, or they failed to initialize.

解决方案：

1. 请检查服务器自身的文档和环境变量。
2. 重新启动。

MCP 工具调用失败

Cause: The server received the request but couldn't execute it.

解决方案：

• 请在工具卡中查看特定错误。
• 确认已提供所需的参数。
• 确认基础资源（文件、数据库、API）可以访问。
