What probably matters to youSection of the release
What
MCP servers are outside programs that add tools to Claude Code, and some are reached over HTTP. Claude Code has a new way to classify how it connects to them.
The step that decides an MCP server's connection mode now receives a ccrToolport value. It is true for HTTP servers whose address passes a toolport check. Before, only inProcess and ccrProxy were passed.
When ccrToolport is set, the connection is labelled ccr-toolport. This takes precedence over ccr-proxy for HTTP servers. Before, the choice was only between ccr-proxy and http.
Why
This adds a separate route for certain HTTP MCP servers. It shows up as its own ccr-toolport label instead of being grouped under ccr-proxy or plain http.
