Use Kling in WorkBuddy.
Kling 3.0 by Kuaishou generates video from text or images at up to 1080p with native audio, multi-shot scenes, and 3–15 second durations. WorkBuddy speaks MCP natively — add RunAPI as an MCP server once and the workbench agent can send a Kling prompt, wait on the async task, and hand back the finished video URL.
Use the runapi MCP server to generate a video with Kling 3.0.
Requirements:
- Use model "kling-3.0".
- Prompt: a drone shot pulling back from a mountain lake at sunrise, mist
rising off the water, cinematic lighting.
- Set duration_seconds to 5, aspect_ratio to "16:9", and
output_resolution to "1080p".
- Enable native audio with enable_sound: true.
- The task is async. Wait for it to complete, then report the video URL
and the cost.

Use Kling in WorkBuddy in three steps
Add RunAPI as an MCP server
Register an MCP server named runapi in WorkBuddy pointing at https://runapi.ai/mcp over streamable HTTP, with the Authorization header reading your key from RUNAPI_API_KEY. One server covers Kling alongside every other RunAPI model.
url: https://runapi.ai/mcp
transport: streamable_http
auth: Bearer $RUNAPI_API_KEY
Prompt the workbench agent
Ask WorkBuddy to generate a video with Kling 3.0. Include the scene description, duration_seconds (3–15), aspect_ratio, and optionally enable_sound for native audio. For image-driven generation, attach a first frame image URL and the agent uses the image_to_video tool instead.
Use the runapi MCP server to generate a 5-second Kling 3.0 clip: ...
Let the agent run the tool and collect the result
WorkBuddy calls the Kling tool through the runapi MCP server and receives a task_id immediately. The agent polls the async task until it completes — typically 30–120 seconds depending on duration and resolution — then reports the video URL back in the workbench.

What is Kling on WorkBuddy?
Kling 3.0 by Kuaishou is known for cinematic-quality video with strong cloth simulation, fluid dynamics, and motion physics. It generates clips from text or images at up to 1080p with native audio and multi-shot scenes. WorkBuddy reaches it through the runapi MCP server — the workbench agent calls Kling as a standard tool with the single key in RUNAPI_API_KEY, and RunAPI handles the async task lifecycle underneath.
Kling use cases
B-roll and establishing shots
Ask WorkBuddy for scene-length B-roll footage on tight deadlines — nature shots, travel content, and environment footage where Kling's motion physics and cinematic lighting stand out.
Product lifestyle content
Create product videos for food, fashion, or lifestyle brands from a single image or text prompt, with natural camera movement and realistic material rendering.
Social media shorts
Produce short clips for TikTok, Reels, or YouTube Shorts with cinematic framing. Set duration_seconds to 5 or 10 for platform-ready lengths.
Kling + WorkBuddy questions
Yes. WorkBuddy speaks MCP natively. Add RunAPI as an MCP server with your RUNAPI_API_KEY and the workbench agent can call the Kling text_to_video and image_to_video tools directly — no plugins or separate video service accounts.
Kling charges per second of generated video. The rate depends on output_resolution and whether enable_sound is on. A 5-second 720p clip without sound is the cheapest option; 1080p with sound costs roughly twice as much per second. Check the RunAPI pricing page for exact rates.
No. RunAPI only bills for completed generations. If the task fails or times out, the reserved credits are rolled back to your account balance, and WorkBuddy simply reports the failed status.
Yes. Ask WorkBuddy to enable sound, which sets enable_sound to true in the tool call. Kling 3.0 generates synchronized audio matching the video content. Sound generation increases the per-second cost — at 720p, sound adds about 3 cents per second.
Kling 3.0 has a separate motion_control tool for applying motion presets to a source image with a reference video, exposed through the same runapi MCP server. The text_to_video tool relies on prompt descriptions for camera direction.
