Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 5 capabilities

We ship only the actions that matter.

Capability set01 / 02

01-03

3 capabilities in this set.

Part of 5 available through Nominatim.

  1. 01

    Reverse geocode

    This capability converts GPS coordinates into human-readable addresses. It provides details like city, state, and country at various levels of granularity.

  2. 02

    Get details

    This capability retrieves full metadata for a specific OSM object. You get the display name, bounding box, parent hierarchy, and even linked Wikipedia articles.

  3. 03

    Get status

    This capability checks the current operational status and response latency of the Nominatim service. Use it to confirm the connection is healthy before running larger tasks.

Capability set02 / 02

04-05

2 capabilities in this set.

Part of 5 available through Nominatim.

  1. 04

    Lookup osm

    This capability fetches information for specific OpenStreetMap objects using their unique IDs. It returns the display name, coordinates, and bounding box for nodes, ways, or relations.

  2. 05

    Search

    This capability finds places by name or address. It returns structured results including coordinates, address components, and bounding boxes.

Real work

What teams actually run

01

Location Verification

Confirm that a set of coordinates actually points to the intended building or landmark.

02

Spatial Data Extraction

Pull structured city, state, and postal code data from raw address strings.

03

Geographic Research

Investigate the relationship between different administrative regions using OSM object hierarchies.

04

Map Data Enrichment

Get bounding boxes and Wikipedia links for specific geographic features.

Automate a task

Put Nominatim to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

Nominatim works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put Nominatim to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Connect your client

One URL. Every client.

Activate the Connector, copy your link, and paste it into the client you already use. 5 capabilities arrive ready to run.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of Nominatim, so you can see the experience inside your AI.

It does not authenticate your account with Nominatim. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work Nominatim owners hand off.

This MCP is built for anyone needing reliable, open-source geographic data without the overhead of managing API credentials.

  • 01

    Developers

    They use the MCP to geocode addresses and convert coordinates without paying for commercial geocoding APIs.

  • 02

    Data Analysts

    They hand off batch geocoding tasks to the agent to extract structured location data.

  • 03

    Researchers

    They use the agent to explore administrative boundaries and place hierarchies within OpenStreetMap.

FAQ

Questions Nominatim owners ask.

  • 01

    Do I need an API key for Nominatim?

    No. This MCP uses OpenStreetMap data and does not require you to manage or provide any API keys.

  • 02

    Which AI clients can use this MCP?

    You can use this with any MCP-compatible client, including Claude, Cursor, and Windsurf.

  • 03

    Is there a limit on how many searches I can do?

    The search capability is rate limited to one request per second.

  • 04

    Can I get the bounding box for a city?

    Yes. The search and lookup capabilities provide bounding box data for cities, countries, and other regions.

  • 05

    What kind of OSM objects can I look up?

    You can look up nodes, ways, and relations using their specific OSM IDs.

  • 06

    Do I need an API key?

    No! Nominatim is completely free and requires no authentication. It's powered by the OpenStreetMap community. Just subscribe and start searching. Rate limit is 1 request per second.

  • 07

    How accurate is the geocoding?

    Nominatim uses OpenStreetMap data, which is crowd-sourced and varies by region. Urban areas typically have very accurate results. Use addressdetails=1 to get structured address components and namedetails=1 for multi-language names.

  • 08

    Can I convert coordinates to an address?

    Yes! Use reverse_geocode with latitude and longitude. Returns the nearest address with street name, house number, city, state, postal code and country. Supports different zoom levels for varying detail granularity.

  • 09

    What is an OSM ID and how do I use it?

    OSM IDs are unique identifiers for OpenStreetMap objects: N for nodes (points), W for ways (lines/areas), R for relations (groups). Use lookup_osm with IDs like 'W123456' or 'N987654'. Use get_details for comprehensive info on a single object.
