## Why This Package?

`@runapi.ai/topaz-mcp` is a focused Model Context Protocol server for the **Topaz** model line on RunAPI.
It gives MCP-compatible assistants direct access to 2 endpoints and 2 model variants without loading the full RunAPI catalog.

Use this per-model server when an agent should stay scoped to Topaz. Use [`@runapi.ai/mcp`](https://github.com/runapi-ai/mcp) when one assistant should discover every RunAPI model line.

---

## Install

Add it to Claude Code:

```bash
claude mcp add topaz -s user -- npx -y @runapi.ai/topaz-mcp
```

Use project scope when the server should be shared with a repository:

```bash
claude mcp add topaz -s project -- npx -y @runapi.ai/topaz-mcp
```

Codex, Cursor, Windsurf, VS Code, Roo Code, and other MCP hosts can use the same stdio command:

```json
{
  "mcpServers": {
    "topaz": {
      "command": "npx",
      "args": ["-y", "@runapi.ai/topaz-mcp"]
    }
  }
}
```

`check_pricing` works before sign-in. For task creation and status polling, ask your assistant to call the `login` tool. It opens a browser login and saves credentials to `~/.config/runapi/config.json`, the same file used by `runapi login`.
Headless and CI hosts can still set `RUNAPI_API_KEY` before starting the MCP host.

Ready-made examples are in [`examples/`](examples/) for Claude, Cursor, Windsurf, VS Code, and Roo Code.

## Tools

| Tool | Auth | Purpose |
|---|---|---|
| `upscale_image` | Yes | Create a Topaz upscale image task and optionally wait for a terminal status. Returns the task id, status, and output URLs. |
| `upscale_video` | Yes | Create a Topaz upscale video task and optionally wait for a terminal status. Returns the task id, status, and output URLs. |
| `get_task` | Yes | Fetch the current status and latest payload for an existing task. |
| `check_pricing` | No | Look up current pricing for a Topaz model and endpoint. |

---

## Models

Topaz covers 2 model variants across 2 endpoints. Each tool accepts the models listed for it:

| Tool | Models |
|---|---|
| `upscale_image` | `topaz-upscale-image` |
| `upscale_video` | `topaz-upscale-video` |

Model availability can change between releases. Use `check_pricing` or the [Topaz model page](https://runapi.ai/models/topaz) for the current catalog view.

---

## Agent Prompts

Ask your assistant in natural language; it can inspect pricing, create the task, and return the task id plus output URLs.

### Create a task

```text
Run a Topaz upscale image task with RunAPI.
```

The assistant can call `check_pricing`, then `upscale_image`, and return the task id, status, and output URLs.

### Submit without waiting

```text
Create the task but don't wait for it to finish.
```

The assistant calls the create tool with `wait: false` and returns the task id. Check on it later with `get_task`.

### Check pricing before creating

```text
Check current Topaz pricing, then create the task if it matches my request.
```

The assistant calls `check_pricing` and can link to the [Topaz model page](https://runapi.ai/models/topaz) for the canonical catalog entry.

---

## Configuration

The server resolves auth in this order:

1. `RUNAPI_API_KEY` environment variable, useful for headless and CI hosts
2. `~/.config/runapi/config.json`, created by the MCP `login` tool or `runapi login`
3. No key, which still allows `check_pricing`

The config file is normally managed by login. A pre-provisioned headless config can use:

```json
{
  "apiKey": "your_runapi_key"
}
```

Do not commit real API keys.
