GeoJSON Map Visualizer MCP App

Visualize GeoJSON data directly in Claude Desktop. Ask Claude to map information it finds or generates, and see it rendered on an interactive map.

Requirements

• Python 3.10+

• Claude Desktop (macOS, Windows, or Linux)

• Git

Set up and use MCP on Claude Desktop

1. Download and set up

git clone https://github.com/benatfroemming/geo-mcp.git
cd geo-mcp
python3 -m venv .venv
source .venv/bin/activate   # Windows: .venv\Scripts\activate
pip install -r requirements.txt

2. Get the path to your venv's Python

which python      # Windows: where python

Copy the full path it prints, e.g. /Users/yourname/geo-mcp/.venv/bin/python (macOS/Linux) or C:\Users\yourname\geo-mcp\.venv\Scripts\python.exe (Windows).

3. Edit the Claude Desktop config

Open the config file for your platform:

On macOS, you can open it directly with:

open -e ~/Library/Application\ Support/Claude/claude_desktop_config.json

Add your server under mcpServers, using the full absolute paths for both the Python binary and main.py from step 2:

{
  "mcpServers": {
    "Map": {
      "command": "/Users/yourname/geo-mcp/.venv/bin/python",
      "args": [
        "/Users/yourname/geo-mcp/main.py"
      ]
    }
  }
}

Note: If the file already has other entries under mcpServers, merge this in as an additional key rather than replacing the whole file.

4. Restart Claude Desktop

Fully quit the app (⌘Q on macOS) and reopen it. Go to Settings → Connectors to verify you see Map listed as connected, with the type Desktop and permission set to Always Allow.

5. Ask Claude

Ask Claude to visualize GeoJSON data, or to map information it can search for online. For example:

"Show me a map of national parks in California" "Plot the boundary of Yellowstone National Park" "Map the top 5 largest cities in Brazil"

Mapping local GeoJSON files is coming soon.
