agent: mcp
When does this happen?
IF MCP server fails to initialize in Claude Desktop with JSON parse error 'Unexpected token E' due to uv not locating the project directory.
How others solved it
THEN Add the `--directory` argument to the uv command in claude_desktop_config.json, specifying the full path to the project root. This ensures uv resolves the correct project context before running the server.
"MyServer": {
"command": "/Users/me/.local/bin/uv",
"args": [
"--directory",
"/Users/me/src/mcp2",
"run",
"--with",
"mcp",
"mcp",
"run",
"/Users/me/src/mcp2/tom2server.py"
]
