Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Package points at a different repository muxinc/mux-ts, muxinc/mux-node-sdk
пакет @mux/mcp ссылается на muxinc/mux-node-sdk

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Connect this server

Endpoint below is the one we actually reach during checks — not the one copied from a README. Last verified 6 min ago.

run in your terminal
claude mcp add mcp --transport http https://mcp.mux.com
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp": {
      "url": "https://mcp.mux.com"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mcp]
url = "https://mcp.mux.com"
.cursor/mcp.json
{
  "mcpServers": {
    "mcp": {
      "url": "https://mcp.mux.com"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "mcp": {
      "url": "https://mcp.mux.com"
    }
  }
}

This one needs environment variables set before it will start: MUX_TOKEN_ID (Your Mux access token ID), MUX_TOKEN_SECRET (Your Mux access token secret), MUX_SIGNING_KEY (Your JWT signing key ID, for use with signed playback IDs), MUX_PRIVATE_KEY (Your JWT private key, for use with signed playback IDs). The author declared them in the registry entry; get the values from the project itself.

Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

docs
search_docs
Search SDK documentation to find methods, parameters, and usage examples for interacting with the API. Use this before writing code when you need to discover the right approach.
execute
execute
Runs JavaScript code to interact with the Mux API. You are a skilled TypeScript programmer writing code to interface with the service. Define an async function named "run" that takes a single parameter of an initialized SDK client and it will be run. For example: ``` async function run(client) { const asset = await client.video.assets.create({ inputs: [{ url: 'https://storage.googleapis.com/muxdemofiles/mux-video-intro.mp4' }], playback_policies: ['public'] }); console.log(asset.id); } ``` You will be returned anything that your function returns, plus the results of any console.log statements. Do not add try-catch blocks for single API calls. The tool will handle errors for you. Do not add comments unless necessary for generating better code. Code will run in a container, and cannot interact with the network outside of the given SDK client. Variables will not persist between calls, so make sure to return or log any data you might need later. Remember that you are writing TypeScript code, so you need to be careful with your types. Always type dynamic key-value stores explicitly as Record<string, YourValueType> instead of {}.

Mux — questions

Answers built from our own checks of this server.

What can Mux do?
It exposes 2 tools, read directly from the server on our last check. Among them: execute, search_docs. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Mux working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 261 ms. The bar chart above shows every period we have measured.
How do I connect Mux?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Mux need an API key?
No. Mux completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Mux?
It answers our handshake in 261 ms on average, which is faster than 55% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Mux?
The npm package @mux/mcp was installed 414 times in the last week. Week over week that is +556%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Mux open source?
Yes — it is published under the Apache-2.0 licence, written in TypeScript, 181 stars on GitHub and 12 open issues. The source link is on this page, so you can read exactly what it does with your data before you connect it.
