# gandora MCP spike
|
|||
|
|
|
|||
|
|
A throwaway experiment, not part of the page. Question: can a gandora player run as an MCP App inside claude.ai and
|
|||
|
|
play audio, and by which path?
|
|||
|
|
|
|||
|
|
The chat Visualizer sandbox (Oct 22 2026) played Web Audio but refused `<audio>` from dev.gandora.lol and teahub.xyz
|
|||
|
|
(MediaError code 4: CSP). An MCP App's UI resource can declare its own domains, and can call its server's tools
|
|||
|
|
through the host, so this probe tests three paths:
|
|||
|
|
|
|||
|
|
1. **synth**: Web Audio, no network (control)
|
|||
|
|
2. **remote**: `<audio>` from dev.gandora.lol, declared in the resource's `_meta.ui.csp.resourceDomains`
|
|||
|
|
3. **blob**: the UI calls `get_track` through the host bridge, gets base64 mp3, plays it from a `blob:` URL
|
|||
|
|
|
|||
|
|
`worker.js` is a single stateless Cloudflare Worker speaking MCP over Streamable HTTP (POST `/mcp`, JSON replies).
|
|||
|
|
Tools: `open_probe` (shows the UI) and `get_track` (app-only). Deployed as `gandora-mcp` at
|
|||
|
|
`https://gandora-mcp.yolopreneur.lol/mcp` by teahubxyz/time › Actions › gandora-mcp (reads this file from `dev`).
|
|||
|
|
|
|||
|
|
Try it: add the URL as a custom connector in claude.ai, then ask Claude to open the gandora probe.
|
|||
|
|
|
|||
|
|
No auth, no keys: it only serves public test clips. Don't grow it in place; the real player server gets designed
|
|||
|
|
from what this answers.
