Connect Codex to After Effects

Codex reads MCP servers from its own config file rather than the ChatGPT settings window. Same address, same account, one sign-in from the shell.

Install the Prism panel
Done in step 1 and step 2.
Sign in from the panel
Done in step 3.
3
Add the server to the config
# ~/.codex/config.toml
[mcp_servers.prism]
url = "https://live.oneprism.io/after-effects"
4
Sign in
codex mcp login prism

Your browser opens once; approve it.

5
Open a composition and confirm the loop
Prism acts on whatever composition is open. Ask: "Tell me about my current composition."

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.

Project-scoped config needs trust

A .codex/config.toml inside a project is ignored unless that project is trusted, so the server silently never loads. Set trust_level = "trusted", or put the entry in ~/.codex/config.toml.

ChatGPT

Connect ChatGPT to your live After Effects project with the Prism MCP server. Choose Streamable HTTP, paste one address, authenticate, and get real keyframes back.

Work

ChatGPT Work, the agent inside ChatGPT, uses the same connectors as ChatGPT. Add the Prism address once, authenticate, and it can carry out work in your open comp.
