This function attempts to infer the correct transport type from the provided argument, handling various input types and converting them to the appropriate ClientTransport subclass. The function supports these input types: - ClientTransport: Used directly without modification - FastMCP or FastMCP1Server: Creates an in-memory FastMCPTransport - Path or str (file path): Creates PythonStdioTransport (.py) or NodeStdioTransport (.js) - AnyUrl or str (URL): Creates StreamableHttpTransport (default) or SSETransport (for /sse endpoints) - MCPConfig or dict: Creates MCPConfigTransport, potentially connecting to multiple servers For HTTP URLs, they are assumed to be Streamable HTTP URLs unless they end in `/sse`. For MCPConfig with multiple servers, a composite client is created where each server is mounted with its name as prefix. This allows accessing tools and resources from multiple servers through a single unified client interface, using naming patterns like `servername_toolname` for tools and `protocol://servername/path` for resources. If the MCPConfig contains only one server, a direct connection is established without prefixing. Examples: ```python # Connect to a local Python script transport = infer_transport("my_script.py") # Connect to a remote server via HTTP transport = infer_transport("http://example.com/mcp") # Connect to multiple servers using MCPConfig config = { "mcpServers": { "weather": {"url": "http://weather.example.com/mcp"}, "calendar": {"url": "http://calendar.example.com/mcp"} } } transport = infer_transport(config) ``` )mcpz.py) script_pathz.jszUnsupported script type: httpsse)url)configz(Could not infer a valid transport from: zInferred transport: ) isinstancer rFastMCP1Serverrrrrstrexistsendswithrr ValueErrorr startswithrrr dictrr loggerdebug)rinferred_transportinferred_transport_types rrr=sh)_- Iw7 8-WS\N2I>  Itcz *tI/E/E/G y> " "5 )!5$tYBW!X  ^ $ $U +!3T9@U!V 8 DE E Iv| ,Y1J1J61R"? #y )#  #e +!-$v|Y2O!P !8#y1"  Iti/ 0/y()4  CI;OPP LL'(:';<= rN)%pathlibrtypingrrrrmcp.server.fastmcprr.pydanticr fastmcp.client.transports.baser r fastmcp.client.transports.configr fastmcp.client.transports.httpr fastmcp.client.transports.memoryrfastmcp.client.transports.sserfastmcp.client.transports.stdiorrfastmcp.mcp_configrrfastmcp.server.serverfastmcp.utilities.loggingr__name__r5rr4r/rrrrGs558L?B=6TG)0 H  I/I4DI I @w@+;@ @ G~G2BG G DyD-?D D ItCH~I2DI I 11++1 1  --
