What

Both MCP OAuth providers read credentials through an injectable store rather than a global, and the MCP discovery cache is described by a location record naming the user config directory and a mcp-discovery-cache folder instead of an in-process map. Behaviour is unchanged.

Evidence

mcp-discovery-cache

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