infinitetalk-mcp
This server provides an MCP interface for the RunAPI InfiniteTalk model, allowing AI agents to create audio-to-video tasks, monitor their status, and check pricing.
audio_to_video: Submit a task to generate a video from an audio source using theinfinitetalk-from-audiomodel. Supports an optional source image URL, output resolution (480p or 720p), and can either wait for completion or return immediately with a task ID.get_task: Poll the current status and result payload (including output URLs) for a previously created task using its ID.check_pricing: Retrieve the current pricing snapshot for the InfiniteTalk model and endpoints — no API key required.
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., "@infinitetalk-mcp Turn this audio file into a video using the InfiniteTalk model"
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/infinitetalk-mcp is a focused Model Context Protocol server for the InfiniteTalk model line on RunAPI.
It gives MCP-compatible assistants direct access to 1 endpoint and 1 model variant without loading the full RunAPI catalog.
Use this per-model server when an agent should stay scoped to InfiniteTalk. Use @runapi.ai/mcp when one assistant should discover every RunAPI model line.

Install
Add it to Claude Code:
claude mcp add infinitetalk -s user -- npx -y @runapi.ai/infinitetalk-mcpUse project scope when the server should be shared with a repository:
claude mcp add infinitetalk -s project -- npx -y @runapi.ai/infinitetalk-mcpCodex, Cursor, Windsurf, VS Code, Roo Code, and other MCP hosts can use the same stdio command:
{
"mcpServers": {
"infinitetalk": {
"command": "npx",
"args": ["-y", "@runapi.ai/infinitetalk-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 an InfiniteTalk audio to 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 InfiniteTalk model and endpoint. |
Models
InfiniteTalk covers 1 model variant across 1 endpoint. Each tool accepts the models listed for it:

Model availability can change between releases. Use check_pricing or the InfiniteTalk 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 an InfiniteTalk audio to video task with RunAPI.The assistant can call check_pricing, then audio_to_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 InfiniteTalk pricing, then create the task if it matches my request.The assistant calls check_pricing and can link to the InfiniteTalk 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 4 tools
Each tool targets a clearly distinct action: task creation (audio_to_video), task polling (get_task), pricing lookup (check_pricing), and authentication (login). There is no overlap or risk of misselection between any pair.
Three tools follow a clean verb_noun snake_case pattern (audio_to_video, get_task, check_pricing), and login is a single verb that still reads naturally. Minor deviation but overall predictable.
Four tools is slightly thin but well-matched to a single-model wrapper: submit a job, poll it, check cost, authenticate. Nothing extraneous, though the surface is minimal.
The create-and-poll lifecycle plus auth and pricing is covered, but there is no way to list tasks, cancel/delete a task, or retrieve results separately from status. For a task-based async API, missing cancellation and enumeration are notable gaps.
