Jinglebox for Claude Code

A Claude Code plugin that plays sounds from your Jinglebox workspace when something happens in a session.

| Event | When it plays | |---|---| | turn-done | Claude finished and its answer waits for you | | needs-answer | Claude waits on you: a question, a plan to approve, a permission prompt, or an answer that ends on a question | | long-turn | a turn longer than 60 s finished (instead of turn-done) | | tests-passed / tests-failed | a test command run by Claude passed or failed (artisan test, pest, phpunit, pytest, jest, vitest, go test, cargo test, npm test…) | | pr-created | glab mr create or gh pr create succeeded |

Out of the box every event plays a random short sound of your workspace; set your own with /jinglebox set.

The plugin ships no audio. Each machine downloads its sounds through its own Jinglebox MCP connection, with its own account, and caches them locally (40 sounds at most).

Install

1. Connect the Jinglebox MCP server (once per machine):

   claude mcp add --transport http --scope user jinglebox https://jinglebox.app/mcp
   

   then run /mcp in an interactive claude terminal, pick jinglebox and authenticate.

2. Allow its read-only tools, so the plugin's calls are not refused in auto mode. In ~/.claude/settings.json:

   "permissions": {
     "allow": [
       "mcp__jinglebox__get-sound",
       "mcp__jinglebox__search-sounds",
       "mcp__jinglebox__get-workspace",
       "mcp__jinglebox__list-workspaces"
     ]
   }
   

3. Install the plugin:

   claude plugin marketplace add lamberttraccard/jinglebox-marketplace
   claude plugin install jinglebox@jinglebox
   

   Or try it without installing: claude --plugin-dir ./plugins/jinglebox.

4. Start a new session. If your account has several workspaces, pick one with /jinglebox workspace <slug>.

Commands

/jinglebox                                       current sounds
/jinglebox workspace [slug]                      list or pick the workspace
/jinglebox set <event> 329 | #329 | <sound URL>  a fixed sound
/jinglebox set <event> 21,349,336                random among these
/jinglebox set <event> random [tag]              random short sound of the workspace, or of one tag
/jinglebox set <event> default                   back to the default (random from the workspace)
/jinglebox search <words>                        find sounds and their IDs
/jinglebox test <event>                          play an event's sound now
/jinglebox mute | unmute
/jinglebox export                                your setup as one /jinglebox import line
/jinglebox import <workspace> <event>=<choice>…  apply a shared setup
/jinglebox debug                                 check the MCP call, the playback and the cache

Choices are kept per machine and per workspace, across sessions. A random pick never plays the same sound twice in a row, and the next sound is downloaded ahead so it starts at once. The toast names each sound played, so a random one you like can be pinned with /jinglebox set.

Share a setup

/jinglebox export prints your setup as a single line, for instance:

/jinglebox import my-team turn-done=random:fun needs-answer=177 long-turn=339 tests-passed=325 tests-failed=329 pr-created=344

Paste it wherever your team talks; whoever runs it gets the same workspace and sounds, then can change any of them with /jinglebox set. A choice is a sound ID (177), a list to pick from (21,349,336), random, or random:<tag>. Nothing is hosted: the line is the setup.

Until a workspace is picked (or imported) on an account with several, no sound plays; the plugin says so in a toast, at most once every 10 minutes, like any other failure.

Settings

| Setting | Default | Meaning | |---|---|---| | workspace | empty | the workspace slug; empty to pick it with /jinglebox workspace | | mcp_server | jinglebox | the Jinglebox MCP server's name, as /mcp lists it | | long_turn_seconds | 60 | a turn longer than this plays long-turn | | random_max_seconds | 4 | a random pick only takes sounds this short |

How it works

It is a plugin of Claude Code function hooks (plugins/jinglebox/hooks/register.ts), an early-access API: it needs a Claude Code build that supports it.

• turn.complete, at the end of a main-loop turn: needs-answer when the answer's last paragraph asks a question, else long-turn or turn-done.
• classic.PermissionRequest, and tool.call on AskUserQuestion and ExitPlanMode: needs-answer, at most once every 3 s.
• tool.call on Bash: tests-passed, tests-failed, pr-created.
• The plugin declares the Jinglebox MCP server in its manifest and connects it with $.mcp.connect before its first call, so it works even when the session has not loaded the server's tools yet; when the session already runs the same server (step 1), that connection is reused.
• Sounds come from the MCP's get-sound, are cached in the plugin's store and played with $.audio.play. Random picks draw from search-sounds, refreshed once a day.

Troubleshooting

/jinglebox debug runs each step and says which one fails.

• "MCP server is not connected": the plugin could not connect the Jinglebox MCP server (network, or the server timed out at startup). Run /mcp, reconnect jinglebox, and try again.
• "call refused": the permissions of step 2 are missing.
