### Summary:
Keap (Infusionsoft) MCP connector — all tool calls fail with deprecated gemini-2.5-flash; v3 auth also failing

### Details:
What's happening: My managed Keap/Infusionsoft MCP connector (endpoint https://mcp.pipedream.net/v2, sub-agent mode) returns the same error on every action call:
AI_APICallError: This model models/gemini-2.5-flash is no longer available. Please update your code to use a newer model for the latest features and improvements.
Scope: It's not one action — it fails identically on infusionsoft-list-contacts, infusionsoft-list-users, and others. Since sub-agent mode routes the natural-language instruction through an internal LLM, and that model has been retired by Google, the request dies inside Pipedream before reaching the Keap API. This makes the connector completely unusable.
Example request IDs: e0f8c7ea-0d77-48eb-9a45-fc8112fef415, 9fedf3a4-915b-4dec-85e9-e3522facb696, dc161779-8cc0-4699-8425-53de8e9016b4
v3 attempt: I tried moving to the v3 (tools-only) endpoint, but authorization fails with reference ofid_0b72c889ca8ff98c ("Authorization with Keap Pipedream Connector v3 failed"). Note the managed connector UI only offers the v2 server URL for Keap — v3 isn't selectable through the standard connect flow.
Ask: (1) Update sub-agent mode to use a current, supported model so v2 connectors work again, and (2) look into the v3 Keap authorization failure (ref ofid_0b72c889ca8ff98c).
App: Keap / Infusionsoft (account M317). Connected via Claude desktop connector.
