# Clip Studio MCP

Hosted [Model Context Protocol](https://modelcontextprotocol.io) server for Clip Studio. Add one URL to Claude, Cursor, ChatGPT, or any MCP client and use the **same public Clip Studio products a signed-in human already has** — Video Lab, Topic Shorts, Talking Shorts, Ad Studio, Last Frame, Image Lab, Audio Lab, Story, Ad Lab, library, and free tools — on the **same plan as the website**.

**Endpoint:** `https://clipstudio.ai/api/mcp`  
**Transport:** Streamable HTTP  
**Marketing:** [https://clipstudio.ai/mcp](https://clipstudio.ai/mcp)  
**Public tool list:** [https://clipstudio.ai/mcp.md](https://clipstudio.ai/mcp.md)  
**Repository:** [https://github.com/j-acks0n/clipstudio-mcp](https://github.com/j-acks0n/clipstudio-mcp)  
**Smithery:** [https://smithery.ai/servers/clipstudioai/clipstudio](https://smithery.ai/servers/clipstudioai/clipstudio)

This repo is a connector listing (`server.json`, install snippets, examples). The server is hosted. There is nothing to clone and run.

## Quick start

Paste the URL. Leave OAuth client id empty. Sign in when the client opens Clip Studio, then Approve.

### Claude Desktop / Claude.ai connectors

Customize → Connectors → Add custom connector. Paste:

```
https://clipstudio.ai/api/mcp
```

Connect. Leave OAuth client id empty.

### Cursor

Add an HTTP MCP server in `~/.cursor/mcp.json`. Cursor runs OAuth on first use.

```json
{
  "mcpServers": {
    "clipstudio": {
      "url": "https://clipstudio.ai/api/mcp"
    }
  }
}
```

### ChatGPT (developer mode connector)

Enable developer mode, add a custom MCP connector, paste `https://clipstudio.ai/api/mcp`, then complete Clip Studio Approve.

### Windsurf

Edit `~/.codeium/windsurf/mcp_config.json` (remote field is `serverUrl`):

```json
{
  "mcpServers": {
    "clipstudio": {
      "serverUrl": "https://clipstudio.ai/api/mcp"
    }
  }
}
```

Save, then refresh MCP in Cascade.

### VS Code / Copilot

User or workspace `mcp.json`:

```json
{
  "servers": {
    "clipstudio": {
      "type": "http",
      "url": "https://clipstudio.ai/api/mcp"
    }
  }
}
```

Command Palette → **MCP: Open User Configuration**, or `.vscode/mcp.json` in a workspace.

### Stdio-only clients

Bridge to Streamable HTTP:

```bash
npx -y mcp-remote https://clipstudio.ai/api/mcp
```

Example wrapper:

```json
{
  "mcpServers": {
    "clipstudio": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://clipstudio.ai/api/mcp"]
    }
  }
}
```

## Authentication

One-click OAuth on the first call. Unauthenticated requests — including `initialize` and `tools/list` — return HTTP **401** with `WWW-Authenticate` and protected-resource metadata. The client dynamically registers (OAuth 2.1 + PKCE, public client). You sign in with the Clip Studio account and Approve. Tokens stay on the client.

No client id to paste. If a human cannot do the job on [clipstudio.ai](https://clipstudio.ai), the agent cannot do it here.

## How a paid job works

1. **Quote** (`quote_*`). Does not generate.
2. If the monthly generation allowance cannot cover the quote, the tool returns HTTP **402** with numeric JSON fields (names only — these are API keys, not UI copy):

   ```json
   {
     "requiredCredits": 120,
     "availableCredits": 0
   }
   ```

   Then call `create_checkout_url` with a `priceId` from `get_account.offerCheckout`. It returns a Stripe Checkout URL and does not take card data.
3. **Generate** (`generate_*` / `start_last_frame` / `render_storyboard` / …). Uses this month’s generation allowance.
4. **Poll** the matching `get_*` tool until the job finishes.

Submit and poll. Do not hold the MCP request for a full provider render.

## Example prompts

- Preview a 15-second Topic Short about why most morning routines fail, then quote and generate it.
- List Video Lab models, quote an 8-second 16:9 clip of a running shoe on a wet track, generate, and poll until it is ready.
- Continue my story: load the latest project, write the next part, then render it.
- Check my remaining monthly generation allowance. If a quote returns 402, open checkout from `offerCheckout`.
- Research an Ad Studio clip from this product URL, pick a catalog creator, quote, generate, and poll.

Walkthroughs: [examples/](examples/).

## Keeping this in sync

The tool list mirrors [https://clipstudio.ai/mcp.md](https://clipstudio.ai/mcp.md). When that page changes, update the tables here by hand. See [scripts/sync-tools.md](scripts/sync-tools.md). This repo does not import Clip Studio’s private source.
