Claude Code v2.1.225 7 Aug 2026

OTel export drops repl_code and git_remote_url, promotes MCP server and tool names

You'll notice

Useful3 Signal0

Telemetry

OpenTelemetry export no longer reports your git remote URL and now reports MCP server and tool names.

What

The OpenTelemetry-to-internal-event transform stops reporting two attributes and starts reporting MCP identity in their place.

Details

No longer emits repl_code or git_remote_url.
Emits mcp_server_name and mcp_tool_name, sourced from _PROTO_mcp_server_name and _PROTO_mcp_tool_name.
_PROTO_code and _PROTO_git_remote_url are still stripped from additional_metadata, they are just no longer reported anywhere.

Evidence

_PROTO_mcp_tool_name

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
