Citizen Nexus

An MCP server that fetches data from the Star Citizen wiki and UEX.

Description

This project is an MCP server that gathers data from the Star Citizen Wiki and UEX via their respective APIs, letting new and veteran players alike look up item and vehicle purchase locations, commodity prices, and more directly from their favorite LLM. Plug it into any MCP compatible client accepting stdio, such as Claude.

⚙️ Exposed tools

search_vehicles

Finds Star Citizen flight-ready ships and ground vehicles by name. Returns matching vehicles with key details ( manufacturer, classification, crew, cargo, quantum travel) along with any in-game purchase or rental listings ( terminals, locations, UEC prices).

Parameters:

• query (string, required): Full or partial vehicle name, e.g. "Constellation" or "Drake Cutlass Black"

📝 Requirements

Node >= 24.16.0

You will need an MCP client installed on your computer. I recommend the Claude desktop app. If you run out of usage too quickly, you can install Dive instead and use a Gemini API key from Google AI Studio (500 requests/day with the Gemini 3.1 Flash Lite model).

⚠️ Note: Citizen Nexus was built mainly with Claude in mind. As more tools and use cases are added, other models might give unexpected results.

📦 Installation and setup

Start by cloning the repository and navigating into it, then run:

npm install && npm run build

Next, take note of the full path to the dist/index.js file.

Claude Desktop App

Edit the claude_desktop_config.json file. You can find its location in the Claude app under Settings > Developer > Edit Config. Add the following configuration, replacing path/to/index.js with the path you identified above:

{
  "mcpServers": {
    "citizen-nexus": {
      "command": "node",
      "args": ["path/to/index.js"]
    }
  }
}

Save the file and restart the Claude desktop app. Before using the server in a chat, make sure it is enabled:

Dive

After setting up your model provider, open the MCP Tools Management tab in the settings and click Add / Edit MCP Config. Paste the following configuration into the JSON field, replacing path/to/index.js with the path you identified above:

{
  "mcpServers": {
    "citizen nexus": {
      "transport": "stdio",
      "enabled": true,
      "command": "node",
      "args": ["path/to/index.js"]
    }
  }
}

Click Save. Before using the server in a chat, make sure it is enabled:

ℹ️ Note: If you run into issues with the node command, try replacing it with its full path, which you can find using this command: Get-Command node.
