Aias00 opened a new issue, #6640:
URL: https://github.com/apache/shenyu/issues/6640

   - severity: High
   - files: 
`shenyu-plugin/shenyu-plugin-mcp-server/src/main/java/org/apache/shenyu/plugin/mcp/server/response/ShenyuMcpResponseDecorator.java:72-78`
   - description: In `writeWith`, `doOnNext` appends each chunk to `body` and, 
if `!future.isDone()`, immediately completes `responseFuture` with 
`applyResponseTemplate(this.body.toString())` — i.e. with only the first chunk 
accumulated so far. Subsequent chunks append to `body` but the future is 
already done.
   - impact: Tool-call results are truncated to the first chunk for any 
response delivered in more than one DataBuffer.
   - suggested_fix: Complete the future only in `setComplete()` (or use 
`collectList()` then complete), not per-chunk.
   - confidence: High
   - related_existing: none
