Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "overspan": {
      "command": "npx",
      "args": [

        "overspan-mcp"
      ],
      "env": {
        "OVERSPAN_API_KEY": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add overspan --env OVERSPAN_API_KEY=your-value -- npx -y overspan-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "overspan": {
      "command": "npx",
      "args": [
        "-y",
        "overspan-mcp"
      ],
      "env": {
        "OVERSPAN_API_KEY": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "overspan": {
      "type": "stdio",
      "command": "npx",
      "args": [

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Common questions

Is Overspan MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: OVERSPAN_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

overspan-mcp

An MCP (Model Context Protocol) server for Overspan, the hosted Overpass API. It gives Claude, Cursor, and any other MCP client direct, metered access to full-planet OpenStreetMap data: raw Overpass QL plus helper tools for nearby search, bounding-box search, counting, and usage checks.

You need an Overspan API key. Plans start at $19/month at overspan.dev; the key arrives by email after checkout, no account needed.

Quickstart

Claude Code

claude mcp add overspan --env OVERSPAN_API_KEY=YOUR_KEY -- npx -y overspan-mcp

Claude Desktop, Cursor, and other JSON-configured clients

"mcpServers": { "overspan": { "command": "npx", "args": ["-y", "overspan-mcp"], "env": { "OVERSPAN_API_KEY": "YOUR_KEY" } } } }

The key must be in the server's env block. MCP clients start servers with their own environment, so a variable exported in your shell profile will not reach it. Treat any config file containing the key as a secret; in Claude Code's .mcp.json you can write "OVERSPAN_API_KEY": "${OVERSPAN_KEY}" to keep the key in your environment and out of the file.

Tools

Tool	What it does
`overpass_query`	Run a raw Overpass QL query. The escape hatch when the helpers are too narrow.
`find_nearby`	Features matching tag filters within a radius of a point.
`features_in_bbox`	Features matching tag filters inside a bounding box.
`count_features`	Count matches in an area without returning them. Cheap; use it before pulling data.
`get_usage`	The key's tier, limits, month-to-date quota, and recent requests. Never consumes quota.

The server also exposes two resources the model can read (overspan://overpass-ql, a QL cheat sheet, and overspan://differences, how Overspan differs from the public servers) and one prompt (write-bounded-overpass-query).

Behaviour worth knowing

The key is sent as an Authorization: Bearer header, never in a URL.
Every successful tool result carries a quota line ([quota] 49998 of 50000 monthly requests remaining) so an agent can pace itself. get_usage gives the full picture and is free to call.
Errors come back in plain language with the gateway's error code, what it means, and whether to retry. Rejected requests do not consume quota, and a runaway loop is bounded by the key's own rate and concurrency caps, never by a larger bill.
Oversized responses are trimmed to fit a model's context: for Overpass JSON the element list is cut and the result says how many elements were dropped. Raise the cap with OVERSPAN_MAX_RESPONSE_CHARS if you want more.
Queries without [timeout:] get 25 seconds. Set it explicitly for heavy queries, up to your tier's cap.

Environment variables

Variable	Required	Default	Purpose
`OVERSPAN_API_KEY`	yes		Your Overspan API key
`OVERSPAN_API_URL`	no	`https://api.overspan.dev`	Override the API endpoint
`OVERSPAN_MAX_RESPONSE_CHARS`	no	`48000`	Truncation threshold for tool results

Data licence

Results are OpenStreetMap data, licensed under the Open Database License. Anything you publish that shows or derives from this data needs a visible credit reaching openstreetmap.org/copyright. Your Overspan subscription pays for hosting and access, not for the data, and does not change those obligations.

Development

npm install

npm run build npm test

The test suite covers the query builders, response shaping, error mapping, and a full in-memory MCP client round trip.
