What
The fetch of MCP (Model Context Protocol) servers hosted on claude.ai now requests include_additional_installs=true. Entries flagged as an additional install are collected separately, sorted by creation time, and appended after the primary de-duplicated list. If the extended request fails with certain errors, Claude Code retries once against the plain endpoint (without additional installs) without using up a full attempt from the normal retry budget, and logs a telemetry reason for the fallback.
Why
This surfaces MCP servers that were installed as extras and weren't previously shown, while keeping server fetching resilient if the new request parameter isn't supported.
