Connect your AI to After Effects
One address, and it is the same for everyone.
https://live.oneprism.io/after-effectsIt carries no secret, so you can paste it into a shared config or a public thread. Signing in is what connects it to your account, and you approve that once per client, in your browser.
Ask the agent to do it
If your client is a CLI or a coding agent, you do not have to find its settings at all. Paste this and let it configure itself:
Add this MCP server to your config, with the streamable HTTP transport and
browser sign-in: https://live.oneprism.io/after-effects
Then run whatever auth command you need and tell me when it is connected.| Client | What it will reach for |
|---|---|
| Claude Code | claude mcp add |
| Kimi Code | kimi mcp add --transport http --auth oauth |
| Qwen Code | qwen mcp add --transport http |
| OpenCode | opencode mcp auth, or it detects the 401 and runs OAuth itself |
| Codex · Cursor · Windsurf · Cline | Its own MCP config file |
The browser approval is still yours. An agent can write the config and run the command, but signing in happens under your account.
Pick your client
Each page has the exact menu path, the exact transport setting, and the mistake that client's setup usually trips on.

If the client was already open, quit it and open it again
Save the address, then run the client's sign-in step. If your AI client was open before the address existed and does not show Prism, quit it and open it again: most clients load their connections at launch. Then open a composition and ask for it by name.
Common questions
Yes. Prism is an MCP server for Adobe After Effects, published as io.oneprism/after-effects in the official MCP Registry. It reads the live composition and writes native layers and keyframes back, rather than generating a script for you to paste and run. Other After Effects MCP servers exist too, some local and some hosted: After Effects MCP servers compared.
No. It is public and identical for everyone. Your account is what signing in establishes, and that never travels in the address.
Yes. Add the same address to as many as you like. Each asks you to approve it the first time, and you can switch freely after that.
Almost always one of two things: the remote transport was not selected, so the client is trying to launch a program that does not exist, or the browser approval was never completed. Check both, then see troubleshooting.
