Audio Delivery Network

@audiodn/mcp

Model Context Protocol server for AudioDN.

Exposes the AudioDN REST API as MCP tools so AI agents (Cursor, Claude Desktop, Claude Code, VS Code, Codex, etc.) can configure audio hosting on a user's behalf, plus offline, read-only knowledge tools grounded in the canonical AudioDN OpenAPI spec and documentation so agents look up the correct endpoints instead of guessing.

Install in Cursor

One-click install (hosted endpoint, zero setup — knowledge/doc tools work immediately):

To enable the live API tools, set ADN_API_KEY (an adn_... key from the dashboard) in your environment before launching Cursor; the hosted endpoint picks it up from the Authorization header. Prefer a local stdio server? Use this button instead:

Both correspond to the mcp.json shipped with this plugin. See Cursor's MCP docs for manual setup.

Install

npm install -g @audiodn/mcp
# or run on demand
npx @audiodn/mcp

Configure

Set a server-side AudioDN API key (mint one in the dashboard at https://account.audiodeliverynetwork.com under Settings → API Keys).

export ADN_API_KEY="adn_..."
# Optional overrides:
# export ADN_API_BASE_URL="https://api.audiodelivery.net"  # default
# export ADN_MCP_ALLOW_DELETE=1     # enable destructive delete tools (off by default)
# export ADN_MCP_LIVE_DOCS=1        # refresh bundled docs from the public site at startup
# export ADN_MCP_TIMEOUT_MS=30000   # per-request timeout

Environment variables

Safety model

• Reads and knowledge tools are annotated read-only and always available.
• Create/update tools run with the API key but are annotated so MCP clients can prompt for approval; the client is the human-in-the-loop layer.
• The two delete tools (adn_delete_creator, adn_delete_collection) are hidden and refuse to run unless the server is started with ADN_MCP_ALLOW_DELETE=1. Set it once to opt in.

Hosted (remote) endpoint

Besides the local npx stdio server above, AudioDN runs the same tool set as a hosted Streamable HTTP endpoint on Cloudflare Workers, so clients that support remote MCP servers can connect without installing anything.

• URL: https://mcp.audiodelivery.net/mcp — the MCP endpoint. The root / serves a human landing page in a browser (and JSON for tooling), and /health returns machine-readable server info.
• Auth — bring your own key: the endpoint is public and stores no secrets. Knowledge/doc tools work with no key. To enable the live API tools, send your AudioDN API key on every request as either header:

Authorization: Bearer adn_...
# or
X-ADN-API-Key: adn_...

• Deletes are never exposed on the hosted endpoint, regardless of key.

Example client configuration (clients that support a remote/HTTP MCP URL):

{
  "mcpServers": {
    "audiodn": {
      "url": "https://mcp.audiodelivery.net/mcp",
      "headers": { "Authorization": "Bearer adn_..." }
    }
  }
}

The hosted Worker lives in worker/ and is deployed with Wrangler (npm run deploy); it is not part of the published npm package.

Use with Cursor

Settings → Tools & Integrations → MCP (or edit ~/.cursor/mcp.json):

{
  "mcpServers": {
    "audiodn": {
      "command": "npx",
      "args": ["-y", "@audiodn/mcp"],
      "env": { "ADN_API_KEY": "adn_..." }
    }
  }
}

Use with Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (or the equivalent on your OS), then restart the app:

{
  "mcpServers": {
    "audiodn": {
      "command": "npx",
      "args": ["-y", "@audiodn/mcp"],
      "env": { "ADN_API_KEY": "adn_..." }
    }
  }
}

Use with Claude Code

claude mcp add audiodn --env ADN_API_KEY=adn_... -- npx -y @audiodn/mcp

Use with VS Code (Copilot) / Codex / Windsurf

Any client that speaks MCP over stdio uses the same command. For VS Code, add to .vscode/mcp.json:

{
  "servers": {
    "audiodn": {
      "command": "npx",
      "args": ["-y", "@audiodn/mcp"],
      "env": { "ADN_API_KEY": "adn_..." }
    }
  }
}

For Codex CLI (~/.codex/config.toml):

[mcp_servers.audiodn]
command = "npx"
args = ["-y", "@audiodn/mcp"]
env = { ADN_API_KEY = "adn_..." }

Tools

Knowledge tools (read-only, offline, no API key needed)

Live API tools

Resources

The server also exposes canonical docs as MCP resources for clients that attach context directly: audiodn://openapi.json, audiodn://llms-full.txt, and audiodn://guide/{topic} for each guide.

Example flow

An agent helping a user host a podcast might call:

1. adn_get_guide({ topic: "upload" }) — learn the canonical multi-step flow.
2. adn_create_collection({ title: "My Podcast" })
3. adn_create_upload_session({ collection_id })
4. adn_create_track_in_upload_session({ upload_session_id, file_name: "ep1.mp3" })
5. Your code PUTs the audio bytes to track_upload.upload_url.
6. Poll adn_get_track({ track_id }) until track_status_id === "ready".
7. adn_create_play_session({ scope: "track", track_id }) — returns a signed playback URL that can be embedded directly.

Build from source

npm install
npm run build
npm test           # vitest
npm run smoke      # build + spawn the real binary over stdio
node dist/index.js

Deploy the hosted endpoint

The Cloudflare Worker in worker/ serves the same tools over Streamable HTTP.

npx wrangler login
npm run dev:worker        # local: http://localhost:8787/mcp and /health
npm run deploy            # publish -> https://mcp.audiodelivery.net (custom domain)
curl https://mcp.audiodelivery.net/health

The custom domain mcp.audiodelivery.net is provisioned by Cloudflare from the routes entry in wrangler.toml (the audiodelivery.net zone must be on the same Cloudflare account).

To list on the official MCP registry (registry name net.audiodelivery/mcp, which must match mcpName in package.json): verify the domain once with mcp-publisher login dns --domain audiodelivery.net (add the printed TXT record), confirm remotes[0].url in server.json points at the deployed URL, then mcp-publisher publish.

Keeping docs fresh

Bundled snapshots live in assets/snapshots/. Refresh them from the public site with npm run sync; prepublishOnly verifies they are consistent before a release.
