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"],
      "env": { "RUNAPI_API_KEY": "${RUNAPI_API_KEY}" }
    }
  }
}

Create an API key at runapi.ai and expose it as RUNAPI_API_KEY. check_pricing can run without a key; task creation and status polling require one.

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

Tools

Tool	Auth	Purpose
extend_video	Yes	Create a Runway extend video task and optionally wait for a terminal status. Returns the task id, status, output URLs, and pricing snapshot.
text_to_video	Yes	Create a Runway text to video task and optionally wait for a terminal status. Returns the task id, status, output URLs, and pricing snapshot.
get_task	Yes	Fetch the current status and latest payload for an existing task.
check_pricing	No	Look up the current pricing snapshot for a Runway model and endpoint.

---

Models

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

Tool	Models
extend_video	runway
text_to_video	runway

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 check_pricing, then extend_video, and return 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 before creating

Check current Runway pricing, then create the task if it matches my request.

The assistant calls check_pricing and can link to the Runway model page for the canonical catalog entry.

---

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.
