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"]
    }
  }
}

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

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

what can it do tho 🤔

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

{
  "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:

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

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 💅
