Arcade's AI video tool now works inside Claude, ChatGPT and Gemini via MCP.
Arcade's releases are almost all about AI video. The November release adds an Arcade MCP so users can create and edit videos from Claude, ChatGPT, Gemini and other assistants, with credit costs shown in the chat. It also adds 60 native voices in 15 more languages and one-click variations of a single video. In October, AI video got its own home and users could pick the model behind each video.
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.

Arcade spent the autumn turning its editor into an AI video studio, with style references, curated scenes and model choice. It is now taking that studio into the assistants people already use, and charging per edit in credits. Localisation and variations push it toward producing many versions of one video for different audiences.
Expect more agent-facing work, such as deeper MCP actions or usage-based pricing detail, since the MCP launch already exposes credit costs per edit.

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.
