What the code does

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.

Sends data to a third-party sink keymaster-mcp/src/index.ts:100
  { service: "telegram", key_name: "api_key", check_method: "GET", endpoint: "https://api.telegram.org/bot{KEY}/getMe", auth_type: "url" },

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

This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

run in your terminal
claude mcp add keymaster-mcp -- npx -y @akari-os/keymaster-mcp
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "keymaster-mcp": {
      "args": [
        "-y",
        "@akari-os/keymaster-mcp"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.keymaster-mcp]
command = "npx"
args = ["-y", "@akari-os/keymaster-mcp"]
.cursor/mcp.json
{
  "mcpServers": {
    "keymaster-mcp": {
      "args": [
        "-y",
        "@akari-os/keymaster-mcp"
      ],
      "command": "npx"
    }
  }
}
.vscode/mcp.json
{
  "mcpServers": {
    "keymaster-mcp": {
      "args": [
        "-y",
        "@akari-os/keymaster-mcp"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: USER_KEYMASTER_URL (Keymaster proxy URL), USER_KEYMASTER_TOKEN (Bearer token for Keymaster authentication). The author declared them in the registry entry; get the values from the project itself.

Keymaster MCP — questions

Answers built from our own checks of this server.

Why is there no uptime for Keymaster MCP?
Keymaster MCP runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package @akari-os/keymaster-mcp was installed 43 times last week.
How do I connect Keymaster MCP?
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 runs locally, so the command pulls @akari-os/keymaster-mcp straight from npm; nothing to host, nothing to sign up for.
How many people use Keymaster MCP?
The npm package @akari-os/keymaster-mcp was installed 43 times in the last week. Week over week that is +21%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Keymaster MCP open source?
We cannot say either way: written in JavaScript, 1 stars on GitHub and 2 open issues, but we could not determine the licence, and without one the code is not open source by default.
