Web Search Isolation Exemption for MCP Servers

Entry
JSON All of v2.1.122
EntryKind: in v2.1.122,
ChangesSection of the release
What

Adds a new webSearchIsolationExemptMcpServers init config field that lets specific MCP servers bypass the web search / connector isolation latch.

Details
  • Accepts an array of MCP server names
  • These servers are unioned with the built-in infrastructure server list, so they remain accessible even when the isolation latch is engaged
  • Marked as @internal — intended for SDK/API integrators, not end-user configuration
Evidence

New schema field (search for "webSearchIsolationExemptMcpServers")

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