fr fr what is this

an MCP server that connects AI agents to myinstants.com — the internet's largest soundboard. millions of meme sounds, vine booms, fart noises, anime clips, gaming sfx, whatever you need bestie.

your AI agent can now:

• 🔍 search any sound on myinstants
• 🔴 smash that button and play it through your speakers
• 📂 browse categories — memes, games, movies, reactions, tiktok trends
• 📈 check what's trending — stay current fr fr
• ⏳ wait or don't — block until sound finishes or let it play in the background

this is not a notification beep. this is the entire internet soundboard. your agent has rizz now.

the setup is bussin

npx myinstants-mcp

that's it. that's the setup. no cap.

VS Code / GitHub Copilot

Add to your VS Code MCP config (User or .vscode/mcp.json):

{
  "servers": {
    "myinstants": {
      "command": "npx",
      "args": ["-y", "myinstants-mcp@latest"]
    }
  }
}

Claude Desktop

~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "myinstants": {
      "command": "npx",
      "args": ["-y", "myinstants-mcp@latest"]
    }
  }
}

Cursor

.cursor/mcp.json:

{
  "mcpServers": {
    "myinstants": {
      "command": "npx",
      "args": ["-y", "myinstants-mcp@latest"]
    }
  }
}

[!TIP] works on macOS out of the box (uses native afplay) — no extra installs needed. on linux just sudo apt install ffmpeg. that's it bestie.

what can it do tho 🤔

🔧 Tools

Tool	What it does	It's giving
search_sounds	search myinstants for sounds	"bruh" → 20 results with slugs
browse_category	browse by category	"memes" "games" "reactions"
play_sound	play a sound (by slug, url, or quick search)	{ query: "sad trombone" } plays instantly
get_sound_details*	get details about a sound (views, uploader, duration)	requires MYINSTANTS_DETAILS=true
list_devices*	list available audio output devices	requires MYINSTANTS_DETAILS=true

_{* requires MYINSTANTS_DETAILS=true environment variable}

play_sound options

Parameter	Type	Default	The tea ☕
query	string	—	quick search, plays first result. the goat option.
slug	string	—	exact slug from search results
url	string	—	direct MP3 URL if you're built different
wait	boolean	false	false = plays in background while agent keeps cooking (default 💨). true = blocks until done (for dramatic effect 🎭)

📚 Resources

Resource	The vibe
myinstants://trending	what's bussin rn in the US 🔥
myinstants://categories	all 14 categories no cap
myinstants://best	hall of fame. the GOATs. the legends. 🐐

Categories

anime & manga · games · memes · movies · music · politics · pranks · reactions · sound effects · sports · television · tiktok trends · viral · whatsapp audios

how it works (for the sigma devs)

agent calls play_sound({ query: "vine boom", wait: false })
  → searches myinstants.com
  → finds the MP3 URL
  → streams it through afplay/ffplay/mpv
  → sound plays through your speakers
  → agent keeps cooking while you hear the boom 🍳

sounds queue up automatically. no overlap. your agent can fire multiple sounds and they play one after another. sheesh.

teach your agent to troll you 💀

drop a .instructions.md in your repo (with applyTo: "**" in the frontmatter) and your agent will play sounds while it works. imagine: vine boom when it finds a bug. sad trombone when your tests fail. rick roll mid-code-review for absolutely no reason.

name: "Soundboard"
description: "Sounds for all contexts"
applyTo: "**"

Play sounds using the myinstants MCP server while you work:
- Play `play_sound(query: "vine boom sound")` when you find cursed code
- Play `play_sound(query: "sad trombone")` when the user's code doesn't work
- Play `play_sound(query: "minecraft level up sound")` when you fix something

check our myinstants.instructions.md for the full unhinged setup. your agent will never be an NPC again. 🏆

config

env vars

Variable	Default	The tea ☕
MYINSTANTS_VOLUME	0.5	how loud (0-1). crank it bestie.
MYINSTANTS_WAIT	false	"true" = sounds block until finished. dramatic effect mode 🎭
MYINSTANTS_DEVICE	(system default)	route audio to a specific output device. platform-specific device name.
MYINSTANTS_PLAYER	(auto)	force a specific player: ffplay, mpv, afplay, or paplay.
MYINSTANTS_DETAILS	false	"true" = enables get_sound_details and list_devices tools.

{
  "servers": {
    "myinstants": {
      "command": "npx",
      "args": ["-y", "myinstants-mcp@latest"],
      "env": {
        "MYINSTANTS_VOLUME": "0.8",
        "MYINSTANTS_DEVICE": "Denon AVR-S760H",
        "MYINSTANTS_DETAILS": "true"
      }
    }
  }
}

audio device selection

route sounds to a specific output device instead of system default:

# set device name (platform-specific)
export MYINSTANTS_DEVICE="Denon AVR-S760H"

# force a specific player (optional)
export MYINSTANTS_PLAYER="ffplay"

# enable device listing tool
export MYINSTANTS_DETAILS="true"

discover available devices:

# macOS
ffmpeg -f avfoundation -list_devices true -i "" 2>&1

# Linux (PulseAudio)
pactl list short sinks

# mpv (cross-platform)
mpv --audio-device=help

or use the list_devices tool when MYINSTANTS_DETAILS=true — your agent can discover devices for you. 💅

player support:

Player	Device Flag	Example
ffplay	-audio_device	ffplay -audio_device "Denon AVR-S760H"
mpv	--audio-device=	mpv --audio-device="pulse/alsa_output.usb"
paplay	--device=	paplay --device=bluez_sink.XX
afplay	❌ N/A	macOS system default only (no device selection)

notes:

• default behavior unchanged — uses system default output if MYINSTANTS_DEVICE not set
• afplay on macOS doesn't support device selection — set MYINSTANTS_PLAYER=ffplay or mpv if you need device control
• device names are platform-specific (see discovery commands above)
• Windows PowerShell player doesn't support device selection — install ffmpeg or mpv for device support

audio player support

Player	Platform	Install	Vibe
afplay	macOS	pre-installed 💅	just works. zero effort. slay.
ffplay	everywhere	brew install ffmpeg / apt install ffmpeg	the reliable bestie
mpv	everywhere	brew install mpv / apt install mpv	also valid no cap

auto-detects what you have. tries afplay first on mac, then ffplay, then mpv. fallback chain is bussin.

why tho 💀

because your AI agent should be able to hit you with a vine boom when the code compiles. because sad trombone when tests fail is objectively correct. because the bruh button exists and your agent deserves to press it. this is not delulu — this is the future.

every other MCP sound server plays one notification beep. one beep. that's giving NPC energy. we have millions of sounds. the entire internet soundboard. main character behavior only.

it's giving... open source 💅
