@runapi.ai/veo-3-1-mcp
This server provides MCP-compatible assistants with access to Google's Veo 3.1 video generation API through RunAPI, enabling the following:
Generate videos from text (
text_to_video): Create videos from text prompts usingveo-3.1orveo-3.1-fastmodels, with control over aspect ratio (16:9,9:16,auto), duration (4,6, or8seconds), and input mode (text,first_and_last_frames,reference).Extend existing videos (
extend_video): Continue or extend a previously generated video by referencing a source task ID.Upscale videos (
upscale_video): Enhance video resolution to1080por4K.Poll for task results (
get_task): Fetch the current status and result payload (including output URLs) for any task by its ID.Check pricing (
check_pricing): Look up current pricing for any Veo 3.1 model and endpoint — no API key required.Flexible task execution: All creation tools support optional polling (
wait: true/false), configurable timeout (timeout_ms), and poll interval (poll_interval_ms), allowing synchronous or asynchronous task submission.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@@runapi.ai/veo-3-1-mcp Generate a 10-second video of a sunset over the ocean"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
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.

Install
Add it to Claude Code:
claude mcp add veo-3-1 -s user -- npx -y @runapi.ai/veo-3-1-mcpUse 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-mcpCodex, 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.
Tools
Tool | Auth | Purpose |
| Yes | Create a Veo 3.1 extend video task and optionally wait for a terminal status. Returns the task id, status, and output URLs. |
| 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. |
| Yes | Create a Veo 3.1 upscale video task and optionally wait for a terminal status. Returns the task id, status, and output URLs. |
| Yes | Fetch the current status and latest payload for an existing task. |
| 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 |
| no model parameter |
|
|
| 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:
RUNAPI_API_KEYenvironment variable, useful for headless and CI hosts~/.config/runapi/config.json, created by the MCPlogintool orrunapi loginNo 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.

TDQS
Scored across 6 tools
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.
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.
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.
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.
