Gemini Interactions - Deep Research with MCP servers
=====================================================

Give the Deep Research agent access to external tools via remote MCP servers.
Pass server configs through `mcp_servers`; `type: "mcp_server"` is added
automatically. Only `url` is strictly required; `name`, `headers`, and
`allowed_tools` are optional.

Custom Function Calling tools are NOT supported by Deep Research, but remote
MCP servers are.
