Connect Claude Code to After Effects
Claude Code takes MCP servers from its own config, not from the Connectors list in the Claude app. One command adds Prism; one sign-in links it to your account. The address is the same one every client uses.
claude mcp add --transport http prism https://live.oneprism.io/after-effects| Scope | Where it applies |
|---|---|
| default | This project only |
--scope project | Shared with everyone who checks the repo out |
--scope user | Every project on this machine |
/mcp and pick Prism; or from the shell, claude mcp login prism. Your browser opens once. claude mcp logout prism clears it again.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.
Writing JSON by hand? A url without a type is read as stdio
In .mcp.json or ~/.claude.json, an entry that has a url but no type is treated as a stdio server and skipped. Add "type": "http" (streamable-http is accepted as an alias).
