Proposed fix: [rmcp client] 'SSE event exceeded the maximum size of 16777216 bytes' — large tool results over SSE rejected (default 16 MiB max_sse_event_size)
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Raise StreamableHttpClientTransportConfig.max_sse_event_size for trusted servers, or make the server return resource links / paginate instead of huge inline results.
Option: Increase limit or shrink payloads [evidence: official_recommended_action]
Applies when: See trigger
Steps:
1. config.max_sse_event_size = 64 * 1024 * 1024
2. or return resource_link content instead of inline blobs
Expected: Error no longer occurs
