What

When Claude Code sends a tracing span for an MCP (Model Context Protocol) tool call, it now checks whether the tool belongs to the memory server or is a dynamic SDK-scoped MCP tool. If so, the captured content is replaced with a redaction placeholder before it's recorded in the trace.

Why

This prevents potentially sensitive content from memory-server or dynamic SDK tool calls from being captured in tracing data.
