What

Organizations can now enforce web search and connector isolation policies that restrict MCP connector access within sessions.

Details
  • When isolation is active, affected sessions see: "Connectors are unavailable in this session under your organization's web search / connector isolation policy. Start a new session to use connectors."
  • Web search similarly blocked with a parallel message
  • Isolation is enforced via an isolation latch that checks against a whitelist of MCP commands
  • Gated by enforce_web_search_mcp_isolation feature flag
Evidence

Isolation message (search for "Connectors are unavailable in this session") — d41() at line ~419266

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