Connect DeepSeek to After Effects
Yes. DeepSeek can drive After Effects. Everything in DeepSeek Harness is a plugin, including its MCP client — and that is the part that matters. Swap the built-in client for one that does OAuth and DSH connects like anything else. About five minutes, once.
| DeepSeek surface | Connects | How |
|---|---|---|
DSH + dsh-mcp-manager | Yes | Browser OAuth, PKCE, dynamic client registration |
DSH + dsh-oauth-mcp-client | Yes | Same flow, drop-in for the native client |
| Any OAuth-capable client running DeepSeek | Yes | OpenCode, Cline, Cursor, Zed |
| DSH, built-in client only | No | Static headers only, no OAuth flow |
| DeepSeek app · chat.deepseek.com | No | No MCP client |
Connect DeepSeek to After Effects
The built-in MCP client is not the one you want
@deepseek-ai/dsh-mcp-client accepts a static headers block and nothing else. Prism issues no keys, so there is nothing to put in it. Install an OAuth plugin instead — DSH is built for exactly this.
https://live.oneprism.io/after-effects — the same for everyone, and it holds no secret.dsh-mcp-manager or dsh-oauth-mcp-client. Both replace the built-in client with one that can complete a browser sign-in, and both keep the token across restarts.headers block out entirely — there is no token to put in it.mcp__prism__* and the model can call them like local ones.Or skip the commands: paste the address into the agent itself and ask it to add the MCP server. It can configure its own client.

- "Stagger these layers by two frames and ease them out." proves the write path
- "Transcribe this audio layer into subtitles." proves Prism AI

If it does not work
| What you see | What it usually means |
|---|---|
| DSH asks for an API key | The built-in client is still active. Install an OAuth plugin |
| The server is added but every call is refused | The browser authorisation was never completed |
Tools do not appear as mcp__prism__* | The server failed to register. Check the plugin's own log |
| DeepSeek cannot reach Prism | The panel is closed. It has to be open in After Effects |
| It connects but sees no composition | No comp is active. Open one |
