Topaz MCP Server

What Is This?

@runapi.ai/topaz-mcp is a focused MCP server for the Topaz model line on RunAPI. It lets an MCP-compatible assistant create Topaz tasks, poll their status, and check current pricing — all through a single RunAPI API key.

check_pricing works without a key. Task creation and status polling require RUNAPI_API_KEY. This package is a pure client; it does not run a local generation backend.

Quick Start

Add it to Claude Code:

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

• -s user: global, available in all of your projects.

• -s project: team-shared, written to .mcp.json in the current repo so it can be committed.

For other hosts, or for manual configuration, use this JSON:

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

Create an API key at runapi.ai and expose it as RUNAPI_API_KEY. See examples/ for ready-made config files for Claude, Cursor, Windsurf, VS Code, and Roo.

Tools

Models

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

Call check_pricing for the current price of any model. Model availability can change between releases.

Examples

Ask your assistant in natural language; it uses the tools to confirm pricing and run the task.

Create a task

Run a Topaz upscale image task with RunAPI.

The assistant calls check_pricing to confirm the cost, then upscale_image, and returns the task id, status, and output URLs.

Submit without waiting

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

What does Topaz cost?

The assistant calls check_pricing and shows the current snapshot, or links to runapi.ai/pricing.

Configuration

The server reads the API key in this order:

1. RUNAPI_API_KEY environment variable

2. ~/.config/runapi/config.json

Example config file:

{
  "apiKey": "your_runapi_key"
}

Do not commit real API keys. Get one at runapi.ai; pricing is listed at runapi.ai/pricing.
