Clay lets teams publish workflows as templates and adds healthcare data.
Clay is a go-to-market data platform that combines enrichment, audiences, ads and outbound sequencing. Late October brought Claygent Auto-mode, which picks a model per row for cost, plus MCP client allowlists and per-workflow credit caps. The week of November 2 added Workflow Templates that anyone can copy, a Definitive Healthcare integration, Salesforce traffic through a customer's own proxy, and tags for Audiences segments.
Postiz encrypts channel tokens and lets agents hand out channel-connect links
The 13 November release adds opt-in encryption of channel tokens at rest (local key or AWS KMS), connect links that let the public API or an MCP agent send someone a link to add a channel, Amazon SES for email and 20-item Instagram carousels with alt text. It also closes two access-control holes: plain members could call billing routes, and post saves could carry another organization's ids. October's release added preview comments and a self-hosted MCP connector.

Clay ships a weekly roundup that alternates between widening its data sources and adding the admin controls larger customers ask for. Workflows have become its main unit, now with budgets, triggers from signals and, with templates, a way to share them between workspaces.
Expect templates to grow into a shared gallery and more vertical data providers like Definitive Healthcare to follow.

Security and agent access now ship together. Each release hardens the self-hosted install while giving MCP agents and the API more of the workflow, from preview links in October to onboarding a client's channel in November.
Expect more MCP and API actions around client onboarding and review, and further access-control audits given two fixes in this release alone.
