Common questions

Is overpass.ch safe?

It passed 3 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

overpass.ch MCP server

Hosted Overpass API with an MCP server. AI assistants connected to it query OpenStreetMap data for the whole planet, find places by name, look up heights, and answer from current data.

The data covers every street, shop, building and place mapped in OpenStreetMap and is updated every minute. The Medium and Large plans can also query the map at a past date, back to September 2012.

This repository holds the documentation and the registry entry of the hosted server at https://api.overpass.ch/mcp (sign-in) and https://api.overpass.ch/v1/mcp (API key). There is nothing to install.

Website: https://overpass.ch
Claude directory: https://claude.ai/directory/overpass-ch
Setup guide: https://overpass.ch/guides/overpass-mcp-server
Docs: https://overpass.ch/docs#mcp
Official MCP Registry: ch.overpass/overpass

Setup

In Claude, add overpass.ch from the Claude directory. Claude Code, ChatGPT and other assistants that sign in take https://api.overpass.ch/mcp as a remote MCP server, then open overpass.ch for you to sign in (OAuth). The free plan works too.

Clients that do not sign in send an API key:

Create a free account and an API key at https://overpass.ch/signup.
Add the server to your assistant, either as a URL with the key in it:

   https://api.overpass.ch/v1/YOUR_API_KEY/mcp

or as https://api.overpass.ch/v1/mcp with the key in the X-API-Key header (or Authorization: Bearer YOUR_API_KEY).

Transport: Streamable HTTP. Protocol versions 2026-07-28 and 2025-03-26 to 2025-11-25. Listing the tools does not need a key. Create a separate key for each assistant, so that you can revoke it on its own.

Claude (web, desktop and mobile apps)

Open overpass.ch in the Claude directory and add it, then sign in to overpass.ch and click Allow. In a Team or Enterprise organisation, an owner first adds it under Organization settings → Connectors.

With a key: Customize → Connectors → + Add → Add custom connector. Name: overpass.ch. URL: the URL with your key. Authentication: No sign in.

ChatGPT

Open https://chatgpt.com/plugins, select + and Add custom MCP server. Enter a name, the URL https://api.overpass.ch/mcp under Connection, and OAuth as authentication. Confirm the warning, select Create as a plugin, then sign in to overpass.ch and click Allow. With a key: the URL with your key and no authentication. Your ChatGPT plan or workspace has to allow custom MCP servers.

Claude Code

claude mcp add --transport http overpass https://api.overpass.ch/mcp

Then type /mcp in Claude Code, select overpass and sign in to overpass.ch in the browser. With a key:

claude mcp add --transport http overpass https://api.overpass.ch/v1/mcp \

--header "X-API-Key: YOUR_API_KEY"

Cursor

~/.cursor/mcp.json, with the key in the environment variable OVERPASS_KEY:

"mcpServers": { "overpass": { "url": "https://api.overpass.ch/v1/mcp", "headers": { "X-API-Key": "${env:OVERPASS_KEY}" } } } }

VS Code

.vscode/mcp.json. VS Code asks for the key the first time and stores it:

"inputs": [ { "type": "promptString", "id": "overpass-key", "description": "overpass.ch API key", "password": true } ], "servers": { "overpass": { "type": "http", "url": "https://api.overpass.ch/v1/mcp", "headers": { "X-API-Key": "${input:overpass-key}" } } } }

Other clients

Other clients that speak MCP over Streamable HTTP take the URL with the key, or the URL without it and the X-API-Key header.

As an Agent Plugin

This repository is also an Agent Plugin: plugin.json and mcp.json add the server overpass at https://api.overpass.ch/mcp. On first use the client opens overpass.ch for you to sign in. A client that does not sign in can use https://api.overpass.ch/v1/mcp with the header X-API-Key instead.

Tools

Tool	What it does	Counts as
`overpass_query`	Runs an Overpass QL or XML query on the full planet. The answer starts with counts and the date of the data, then one element per line. Answers over 30,000 characters are cut and can be read in parts with `offset`.	1 request
`overpass_examples`	Finds tested example queries for a topic, from a cookbook of 99 queries.	free
`geocode_search`	Places, addresses and points of interest by name, in English, German or French, with an `overpass_area_id` for searching inside that place.	1 geocoding request
`geocode_reverse`	The address, street, city or country at a point.	1 geocoding request
`elevation_points`	Heights of points: a 2 m grid in Switzerland and Liechtenstein (swissALTI3D), a 30 m grid elsewhere on land (Copernicus), depths at sea (GEBCO).	1 lookup per point
`elevation_profile`	Distance, ascent, descent and heights along a path.	1 lookup per sample
`account_status`	Plan, use this month and the date of the data.	free

All tools only read data. Overpass queries through MCP stop after 120 s at most.

Example questions

How many pharmacies in Zürich are within 200 m of a tram stop?
Which mountain huts in Valais lie above 2,500 m?
List every EV charger in the canton of Bern with operator and power, as a table.
How many cafés did Lausanne have in 2015, and how many today? (Medium and Large plans)

Plans

Tool calls count like the same calls of the REST API.

Plan	Price a month	Overpass requests a month	Queries at a time	History
Free	0	10,000 (30 a minute)	1	no
Small	CHF/EUR 19 or USD 25	100,000	2	no
Medium	CHF/EUR 59 or USD 79	1 million	6	yes
Large	CHF/EUR 149 or USD 199	3 million	10	yes

The free plan is for evaluation and development, and for personal, educational and non-profit projects; commercial use needs a paid plan. Every plan includes 100,000 geocoding requests a month. Prices exclude VAT, and a year costs ten months. Details: https://overpass.ch/pricing

FAQ

Do I need an API key? Yes, for tool calls. The free plan works. Listing the tools works without a key.

What happens when a result is very large? The answer says how many elements there were. The assistant can read the next part with offset, raise max_chars up to 200,000, or narrow the query (out count;, out center 50;, a smaller area).

How is this different from MCP servers that use overpass-api.de? The public server overpass-api.de allows about 100 queries a day for anything that runs regularly, refuses scripts without their own User-Agent and bans addresses after repeated 429 errors. overpass.ch identifies you by your API key, publishes its limits and tells the assistant how long to wait when it reaches one.

What is logged? Tool calls are logged like API requests: the id of the key, never the key, and queries only as a hash.
