Unclear This repair sits behind a server-controlled setting, and nothing shows whether it is switched on.
An MCP server is an outside program that gives Claude Code extra tools. Each tool comes with a schema, a description of the inputs it accepts. When the API rejects a request because one of these schemas is invalid, Claude Code replaces the refused schema and tries again.
That repair used to look only in the main list of tools sent with a request. It now also finds refused schemas in tools that were added partway through a conversation, inside the messages themselves. When it repairs one of these, it replaces the schema and drops a streaming option attached to that tool. It can also now keep track of more than one refused schema for the same tool.
A single faulty tool schema from an MCP server no longer breaks a conversation when that tool was added during the conversation rather than at the start.
