Description
使用nacos+higress 将存量API转换为MCP，访问/mcp/{mcp-server-name}/sse 能正常连接，但是调用tool时有一定几率出现 -32602 Tool not allowed 报错，场景不清楚，可能和并发有关系？
咨询nacos，他们说他们不负责tool的调用，问题在higress这边，请问什么情况下会出现 -32602 Tool not allowed 的报错

Use nacos+higress to convert the existing API to MCP, and access /mcp/{mcp-server-name}/sse to connect normally, but there is a certain chance that the tool will occur when calling the tool -32602 Tool not allowed An error is reported. The scenario is unclear, which may be related to concurrency?
Consult with nacos, they said they are not responsible for the call of the tool. The problem is on the higress side. Under what circumstances will the -32602 Tool not allowed errors occur.
