What
When a program using the Claude Code SDK sends a request to read a resource exposed by an MCP server (a connector that gives Claude access to external tools and data), that request is now handled immediately rather than waiting behind other in-flight control requests. This puts mcp_read_resource in the same fast-path category as the existing generate_session_title request.
Why
This avoids MCP resource reads getting stuck behind slower, unrelated queued requests, so SDK callers get a quicker response.
