Mirelo SFX — Kiro Power
Generate and edit sound for video from inside Kiro: sound effects, Foley and ambience, scored against the footage itself or written from a text prompt, plus extend and inpaint on audio you already have.
This repository is the Kiro Power for the hosted Mirelo MCP server. Installing it registers the MCP server and gives the Kiro agent the context to use it well. It follows the Agent Plugins specification, the open plugin format Kiro powers are built on, so the same package also works in other clients that support the format.
Install
From the Kiro marketplace — find Mirelo SFX at kiro.dev/powers and click Add to Kiro.
From this repository — in Kiro, open the powers panel → Add Custom Power → Import power from GitHub, and paste:
https://github.com/mirelo-ai/kiro-power
Then complete Sign in with Mirelo in the browser window Kiro opens, and check the connection by asking the agent to "check my Mirelo account credits".
What you need
A Mirelo account — free to create at mirelo.ai. There is no API key to manage: the power authenticates with OAuth, and generations bill to the credits on the account you sign in with, the same balance the web app uses.
Try it
Here's my gameplay clip — generate footstep and impact sounds that match the action.
Create a 10-second rainy city street ambience, distant traffic, soft footsteps.
Extend this ambience loop to 45 seconds so it covers the whole scene.
There's a glitch from 0:05 to 0:12 — regenerate just that section, keep the rest as is.

Not on this surface
Music, audio-to-MIDI and multi-stem generation are not exposed through the MCP server. Mirelo does generate music — in Mirelo Studio and its editor plugins.
