What the code does

We have not read this server's code yet

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.

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 mcp-server -- npx -y @locus-dev/mcp-server
~/Library/Application Support/Claude/claude_desktop_config.json
{
  "mcpServers": {
    "mcp-server": {
      "args": [
        "-y",
        "@locus-dev/mcp-server"
      ],
      "command": "npx"
    }
  }
}
~/.codex/config.toml
[mcp_servers.mcp-server]
command = "npx"
args = ["-y", "@locus-dev/mcp-server"]
.cursor/mcp.json
{
  "mcpServers": {
    "mcp-server": {
      "args": [
        "-y",
        "@locus-dev/mcp-server"
      ],
      "command": "npx"
    }
  }
}

        "@locus-dev/mcp-server"
      ],
      "command": "npx"
    }
  }
}

This one needs environment variables set before it will start: PROTOTYPER_API_KEY (Optional: Locus API key for cloud team sync. Prefix ptmcp_. Not required for local stories.yaml mode.), PROTOTYPER_PROJECT_ID (Optional: Locus project UUID for cloud team sync.), LOCUS_STORIES_PATH (Optional: Explicit path to stories.yaml. Defaults to auto-discovery from project root.). The author declared them in the registry entry; get the values from the project itself.

Jonybur — questions

Answers built from our own checks of this server.

Why is there no uptime for Jonybur?
Jonybur 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 @locus-dev/mcp-server was installed 42 times last week.
Is Jonybur still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Jonybur?
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 @locus-dev/mcp-server straight from npm; nothing to host, nothing to sign up for.
How many people use Jonybur?
The npm package @locus-dev/mcp-server was installed 42 times in the last week. Week over week that is +94%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
