Why This Package?

@runapi.ai/runway-mcp is a focused Model Context Protocol server for the Runway model line on RunAPI. It gives MCP-compatible assistants direct access to 2 endpoints and 1 model variant without loading the full RunAPI catalog.

Use this per-model server when an agent should stay scoped to Runway. Use @runapi.ai/mcp when one assistant should discover every RunAPI model line.

Install

Add it to Claude Code:

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

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

claude mcp add runway -s project -- npx -y @runapi.ai/runway-mcp

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

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

checkpricing 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 RUNAPIAPI_KEY before starting the MCP host.

Ready-made examples are in examples/ for Claude, Cursor, Windsurf, VS Code, and Roo Code.

Tools

Models

Runway covers 1 model variant across 2 endpoints. Each tool accepts the models listed for it:

Model availability can change between releases. Use check_pricing or the Runway model page 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

Run a Runway extend video task with RunAPI.

The assistant can call checkpricing, then extendvideo, and return the task id, status, and output URLs.
