About Nominatim MCP Server
Connect to Nominatim and search the world's most comprehensive open-source geographic database through natural conversation — no API key needed.
The OpenAI Agents SDK auto-discovers all 5 tools from Nominatim through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns — chain multiple agents where one queries Nominatim, another analyzes results, and a third generates reports, all orchestrated through the Vinkius.
What you can do
- Address Search — Find any place by name, address or type of place (restaurants, schools, hospitals)
- Reverse Geocoding — Convert GPS coordinates to human-readable addresses
- OSM Lookup — Look up detailed info for any OpenStreetMap object by its ID
- Structured Addresses — Get detailed address components (street, city, state, postal code, country)
- Multi-language Names — Retrieve place names in different languages
- Bounding Boxes — Get geographic boundaries for cities, countries and regions
The Nominatim MCP Server exposes 5 tools through the Vinkius. Connect it to OpenAI Agents SDK in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

Why Use OpenAI Agents SDK with the Nominatim MCP Server
OpenAI Agents SDK provides unique advantages when paired with Nominatim through the Model Context Protocol.
Native MCP integration via `MCPServerSse` — pass the URL and the SDK auto-discovers all tools with full type safety
Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure
Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate
First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output
Nominatim + OpenAI Agents SDK Use Cases
Practical scenarios where OpenAI Agents SDK combined with the Nominatim MCP Server delivers measurable value.
Automated workflows: build agents that query Nominatim, process the data, and trigger follow-up actions autonomously
Multi-agent orchestration: create specialist agents — one queries Nominatim, another analyzes results, a third generates reports
Data enrichment pipelines: stream data through Nominatim tools and transform it with OpenAI models in a single async loop
Customer support bots: agents query Nominatim to resolve tickets, look up records, and update statuses without human intervention
Nominatim MCP Tools for OpenAI Agents SDK (5)
These 5 tools become available when you connect Nominatim to OpenAI Agents SDK via MCP:
get_details
Returns the object's full name, display name, place rank, importance score, bounding box, parent place hierarchy, linked Wikipedia/Wikidata articles and optional extratags. OSM type: N (node), W (way), R (relation). Get detailed info for an OSM object
get_status
Returns status message and response latency. Useful for verifying the service is operational before making other requests. Get Nominatim server status
lookup_osm
IDs are formatted as "type{id}" where type is N (node), W (way) or R (relation). Multiple IDs are comma-separated. Returns the object's display name, coordinates, bounding box and properties. Look up OSM objects by ID
reverse_geocode
Returns the nearest address, city, state, country and other location details. Supports different zoom levels for varying detail granularity. Convert coordinates to an address
search
Returns results with coordinates, bounding box, display name, address components and OSM type/id. Supports structured searches with country codes and viewbox for region prioritization. Rate limited to 1 request/second. Search for places by name or address
Example Prompts for Nominatim in OpenAI Agents SDK
Ready-to-use prompts you can give your OpenAI Agents SDK agent to start working with Nominatim immediately.
"Find the coordinates for the Eiffel Tower."
"What address is at coordinates 40.7128, -74.0060?"
