Why This Package?

@runapi.ai/veo-3-1-mcp is a focused Model Context Protocol server for the Veo 3.1 model line on RunAPI. It gives MCP-compatible assistants direct access to 3 endpoints and 3 model variants without loading the full RunAPI catalog.

Use this per-model server when an agent should stay scoped to Veo 3.1. Use @runapi.ai/mcp when one assistant should discover every RunAPI model line.


Related MCP server: veo-mcp-server

Install

Add it to Claude Code:

claude mcp add veo-3-1 -s user -- npx -y @runapi.ai/veo-3-1-mcp

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

claude mcp add veo-3-1 -s project -- npx -y @runapi.ai/veo-3-1-mcp

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

{
  "mcpServers": {
    "veo-3-1": {
      "command": "npx",
      "args": ["-y", "@runapi.ai/veo-3-1-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/ for Claude, Cursor, Windsurf, VS Code, and Roo Code.

Purpose

extend_video

Yes

Create a Veo 3.1 extend video task and optionally wait for a terminal status. Returns the task id, status, and output URLs.

text_to_video

Yes

Create a Veo 3.1 text to video task and optionally wait for a terminal status. Returns the task id, status, and output URLs.

upscale_video

Yes

Create a Veo 3.1 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 Veo 3.1 model and endpoint.


Models

Veo 3.1 covers 3 model variants across 3 endpoints. Each tool accepts the models listed for it:

Tool

Models

extend_video

no model parameter

text_to_video

veo-3.1, veo-3.1-fast, veo-3.1-lite

upscale_video

no model parameter

Model availability can change between releases. Use check_pricing or the Veo 3.1 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 Veo 3.1 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 Veo 3.1 pricing, then create the task if it matches my request.

The assistant calls check_pricing and can link to the Veo 3.1 model page 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:

{
  "apiKey": "your_runapi_key"
}

Do not commit real API keys.

    B3.4/5.0

    Scored across 6 tools

    Disambiguation5/5

    Each tool targets a clearly distinct action: authentication (login), pricing lookup (check_pricing), task submission for three different video operations, and task polling (get_task). Although upscale_video, extend_video, and text_to_video all wrap the same RunAPI task-creation mechanism, their names and descriptions make the operation each performs unambiguous.

    Naming Consistency4/5

    The set predominantly follows a snake_case verb_noun pattern (upscale_video, extend_video, text_to_video, get_task, check_pricing). The bare 'login' verb is a minor deviation but still readable and conventional for auth.

    Tool Count5/5

    Six tools is a well-scoped set for a single-model video generation wrapper, with each tool earning its place (auth, three generation modes, task status, pricing). Nothing feels redundant or missing at the count level.

    Completeness4/5

    Core lifecycle is covered: authenticate, submit a task, and poll its status/result. Minor gaps exist, such as no task listing/cancellation and no image-to-video variant if the model line supports it, but agents can work around these using get_task and the returned output URLs.
