Released November 9, 2026.
This is a small release with one fix for the people who read your docs through an AI tool. Readers who had visited your docs site many times before could not finish connecting their AI tool to your Docs MCP server. They can now.
Fixes
Frequent visitors can connect to your Docs MCP server
When a reader connected Claude or another AI tool to your Docs MCP server, they could type their email, receive the one-time code and enter it, and then be stopped by an error: “too many SQL variables”. This happened only to readers who had already browsed your docs site many times on the same browser, so the readers most engaged with your docs were the ones who could not get in.
The error came from the last step of sign-in. That step links a reader’s earlier anonymous visits to your site with their identified profile, and it failed when there were a great many earlier visits to link. It now handles any amount of history. Those readers connect normally, and their earlier visits are still linked to their profile, as they are for everyone else.
Readers who hit this error do not need to do anything special. They can connect again the normal way.
