How to Use the Zippopotam.us MCP in VS Code Copilot

Q: How do we get Zippopotam.us data into our VS Code Copilot workflow?

You commit the MCP Server configuration file (mcp.json) to your repository. This shares access to Zippopotam.us across all team members, ensuring consistency.

Q: Does VS Code Copilot handle different types of Zippopotam.us lookups?

Yes. It supports both finding zip codes from a city (lookupnearbycity) and performing reverse lookups using an existing postal code (lookuppostcode).

Standardize location data lookups across your whole team using VS Code Copilot.

Team City Lookups with MCP Server

Using `lookup_nearby_city` ensures every developer on the team uses the same source for city-to-zip code mapping. You commit the configuration, so everyone gets immediate access to Zippopotam.us data. When a teammate needs to validate zip codes based on a major metropolitan area, they just activate Copilot Chat in Agent mode; the tool is already configured and ready.

Shared Postcode Validation

The `lookup_postcode` tool allows your entire team to standardize how location data is validated. Instead of relying on local spreadsheets, every developer uses the shared MCP Server endpoint. This means that if a bug requires verifying coordinates for an address, all developers use the exact same logic and source of truth provided by Zippopotam.us.

Centralized Geo-Intelligence via MCP Server

The overall benefit is centralizing global postal code intelligence into your shared codebase. By configuring this MCP Server, you guarantee that every engineer uses the latest data standards. The team doesn't need individual API keys or local setups; they just need to check the `.vscode/mcp.json` file to access robust location tools.

Setup guide

Set up Zippopotam.us MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Zippopotam.us MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Zippopotam.us tools listed. Try asking: "List my recent Zippopotam.us transactions" and Copilot will invoke them automatically.

.vscode/mcp.json

{
  "mcpServers": {
    "zippopotamus-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
