fix MCP ValidationError on blank stdin lines and bump to 0.4.5
发布于
2026-04-12 17:48:29 +00:00 Some MCP clients send blank lines between JSON messages. The stdio
transport tried to parse every line as JSONRPCMessage, crashing with
a Pydantic ValidationError. _filter_blank_stdin() installs an OS-level
pipe that relays stdin while silently dropping blank-only lines.Closes #201
