Describe the pull request
This PR addresses a critical blocker for Windows users where the MCP server fails to connect to Claude Code, throwing
Invalid JSON: EOF while parsing a valueandConnection closederrors during thestdiostream initialization.Root Causes & Fixes:
fastmcp(locked at<3) fail to properly handle newline characters (\n) in Windowsstdiostreams. Bumped thefastmcpconstraint to>=3.2.4and regenerated theuv.lockfile to pull the upstream fix.README.mdfor Windows users. Using the typicalcmd /cwrapper in Claude's configuration injects unwanted terminal echoes into the stream, crashing the parser. Documented the direct.exeexecution approach using"env": {"PYTHONUTF8": "1"}to ensure stable communication.Testing:
Tested locally on Windows 11 with Claude Code CLI. The server now successfully connects and maintains the stream without parsing crashes.
