What

When two configuration sources define the same MCP server, the merge step was writing into the wrong place and comparing the wrong entry's passthrough tools. It now builds the merged entry and only stores it when something actually changed.

Evidence

return d === o ? t : t.set(r.name, d);

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