What
OpenTelemetry is a standard way to send traces, records of what a program did, to monitoring tools. When tracing is on, the record for each tool call now includes:
anthropic.mcp.server.name, for tools that come from an MCP server (an add-on that supplies tools)
Before, the record held only the tool name in Claude Code's own fields. A failed tool result now also reports whether it was interrupted.
Why
Monitoring tools that understand the standard GenAI attributes can now group and filter Claude Code's tool calls without custom mapping.
