Low-code platform for building internal tools and apps

retool.com ↗

Retool's MCP server is generally available, so AI tools can reach your Retool org directly.

◆Current state
On November 11 Retool made its MCP server generally available, added Claude Fable 5.2 to its model list and turned on web search for AI app building and in-app functions. The week before, MongoDB Atlas and Snowflake gained OAuth sign-in for cloud instances, workflows learned to run as a permission group and Microsoft SQL 1.0/2.0 were retired.
◆Where it's heading
Retool is opening itself to outside agents through MCP while its own AI builder gets new models and live web data. The connection work underneath, with OAuth instead of stored database users, cuts setup and secrets for the data those agents touch.
◆Prediction
Expect more resources to move to OAuth sign-in and the MCP server to gain write or app-building tools; the entries do not yet say what the GA server can do.

    Self-hosted Retool 4.86 Stable

    Retool's 4.86 line reaches the Stable channel for self-hosted customers. The note only points to the full release notes, so the change for self-hosters is the move to a supported stable version rather than any single feature.
