256256On Claude Code v2.1.227 or later, your organization can keep [MCP tool search](/docs/en/mcp#scale-with-mcp-tool-search) on under this variable through [managed settings](/docs/en/managed-settings). What Claude Code sends with that override in place depends on how you connect:
257257 
258* On a direct connection, or through a gateway set with `ANTHROPIC_BASE_URL`, Claude Code keeps sending the tool-search beta header, `defer_loading` tool fields, and `tool_reference` blocks, and strips the rest
258* On a direct connection without the HIPAA configuration, or through a gateway set with `ANTHROPIC_BASE_URL`, Claude Code keeps sending the tool-search beta header, `defer_loading` tool fields, and `tool_reference` blocks
259259* On a cloud provider, or signed in through a [Claude apps gateway](/docs/en/claude-apps-gateway), the override has no effect
260* In a session that [gets the HIPAA configuration](/docs/en/hipaa-setup#check-how-developers-sign-in-and-connect), the override has no effect and tool search stays off

261262The set of capabilities Claude Code sends grows over releases. For current beta header strings, see the [beta headers reference](https://platform.claude.com/docs/en/api/beta-headers); test your gateway against new Claude Code releases rather than pinning to an observed list.
