Varosity MCP Server

@varosity/mcp-server

Stdio MCP server for Varosity AI. Exposes every Varosity tool (generate video, voice, music, render, list models, list templates, webhooks, …) to any MCP-aware host — Claude Desktop, Cursor, Cowork, Continue, etc.

Under the hood it proxies every JSON-RPC call to ${VAROSITY_API_BASE}/api/mcp over HTTPS with your vsk_live_... bearer token. Zero runtime deps.

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "varosity": {
      "command": "npx",
      "args": ["-y", "@varosity/mcp-server"],
      "env": {
        "VAROSITY_API_KEY": "vsk_live_..."
      }
    }
  }
}

Issue a vsk_live_... token at varosity.ai/app/keys/api-keys. Restart Claude Desktop.

Cursor / Cowork / Continue

Any MCP host that supports the command + args + env shape works. Point it at npx -y @varosity/mcp-server with VAROSITY_API_KEY in the env.

Tools exposed

Full list via tools/list. Current surface:

• list_models, list_voices, list_templates
• list_projects, create_project, get_project, create_project_from_template
• generate_video, generate_voice, generate_music
• suggest_model (Smart Router)
• get_job, render_project
• list_webhooks, create_webhook, test_webhook, delete_webhook

Alternative: direct HTTP

If your MCP host supports the Streamable HTTP transport, you can skip this package entirely:

{
  "mcpServers": {
    "varosity": {
      "url": "https://varosity.ai/api/mcp",
      "transport": "streamable-http",
      "headers": {
        "Authorization": "Bearer vsk_live_..."
      }
    }
  }
}

This stdio package exists for hosts that only support the command-spawned stdio transport.

Self-host / point at a different deploy

Set VAROSITY_API_BASE in the env block to override the default https://varosity.ai.
