What is CircleCI?

CircleCI's SSH reruns now open from the browser, through one trusted address.

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

What is Retool?

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

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.

CircleCI's SSH reruns now open from the browser, through one trusted address.

◆ Current state

CircleCI is tidying both ends of the pipeline before December. Config warnings become hard failures on December 14, and the v1 project APIs lose their branches field on December 7 after brownouts on November 17 and December 1. On November 12 Rerun job with SSH moved to a single host, ssh.circleci.com, on ports 22 or 443 with fixed IPs, plus a terminal that opens from the job page. Functions, versioned job-setup programs agents can configure, entered beta on November 4.

◆ Where it's heading

CircleCI is closing old paths (lenient config, v1 API fields, old Xcode images) while making failures easier to reach: job-linked commit statuses last week, browser SSH this week. The newer Functions beta and API v3 are where users are being steered.

◆ Prediction

Expect more debug tools on the job page and further v1 API removals pointing users to v3 before year end.

6.3

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.
