No video transcoding, repackaging only
Chunk durations are fixed, not arbitrary
One origin per CDN resource
Proxy mode has no HLS, DASH or clipping

Run your CDN from an AI agent

An official MCP server ships with the platform. Point Claude, Cursor or any MCP client at it and your agent operates the CDN from plain instructions, with no wrapper code to maintain.

What an agent can do

Create and configure CDN zones and video resources
Purge and warm the cache before a release
Read traffic and cache metrics, estimate cost
Add and manage custom domains
Manage Cloud Storage buckets, imports and files

How it is built

52 tools across CDN, cache, metrics, domains and storage
Read tools always on, writes and deletes off by default
Destructive operations are not implemented at all
Runs over stdio or streamable HTTP
On npm, and in the official MCP Registry, Smithery, Glama, Cursor and LobeHub

One image, every size

Your origin stores one file. The CDN generates, caches and delivers every variant from a query string on your own domain.
