What is the Nominatim MCP Server?
Connect to Nominatim and search the world's most comprehensive open-source geographic database through natural conversation — no API key needed.
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
How it works
- Subscribe to this server
- No API key needed — start searching immediately
- Explore geographic data from Claude, Cursor, or any MCP-compatible client
No API key required — completely free, powered by OpenStreetMap community data.
Who is this for?
- Developers — geocode addresses and convert coordinates without paid geocoding services
- Travelers — find addresses and discover what's at any GPS coordinate
- Researchers — explore OpenStreetMap object details, administrative boundaries and place hierarchies
- Data Analysts — batch geocode addresses and extract structured location data
Built-in capabilities (5)
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
Returns status message and response latency. Useful for verifying the service is operational before making other requests. Get Nominatim server status
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
Returns the nearest address, city, state, country and other location details. Supports different zoom levels for varying detail granularity. Convert coordinates to an address
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
Why CrewAI?
When paired with CrewAI, Nominatim becomes a first-class tool in your multi-agent workflows. Each agent in the crew can call Nominatim tools autonomously, one agent queries data, another analyzes results, a third compiles reports, all orchestrated through Vinkius with zero configuration overhead.
- —
Multi-agent collaboration lets you decompose complex workflows into specialized roles, one agent researches, another analyzes, a third generates reports, each with access to MCP tools
- —
CrewAI's native MCP integration requires zero adapter code: pass Vinkius Edge URL directly in the
mcpsparameter and agents auto-discover every available tool at runtime - —
Built-in task delegation and shared memory mean agents can pass context between steps without manual state management, enabling multi-hop reasoning across tool calls
- —
Sequential and hierarchical crew patterns map naturally to real-world workflows: enumerate subdomains → analyze DNS history → check WHOIS records → compile findings into actionable reports

Frequently asked questions
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.
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.
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.
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.
How does CrewAI discover and connect to MCP tools?
CrewAI connects to MCP servers lazily. when the crew starts, each agent resolves its MCP URLs and fetches the tool catalog via the standard tools/list method. This means tools are always fresh and reflect the server's current capabilities. No tool schemas need to be hardcoded.
Can different agents in the same crew use different MCP servers?
Yes. Each agent has its own mcps list, so you can assign specific servers to specific roles. For example, a reconnaissance agent might use a domain intelligence server while an analysis agent uses a vulnerability database server.
What happens when an MCP tool call fails during a crew run?
CrewAI wraps tool failures as context for the agent. The LLM receives the error message and can decide to retry with different parameters, fall back to a different tool, or mark the task as partially complete. This resilience is critical for production workflows.
Can CrewAI agents call multiple MCP tools in parallel?
CrewAI agents execute tool calls sequentially within a single reasoning step. However, you can run multiple agents in parallel using process=Process.parallel, each calling different MCP tools concurrently. This is ideal for workflows where separate data sources need to be queried simultaneously.
Can I run CrewAI crews on a schedule (cron)?
Yes. CrewAI crews are standard Python scripts, so you can invoke them via cron, Airflow, Celery, or any task scheduler. The crew.kickoff() method runs synchronously by default, making it straightforward to integrate into existing pipelines.
MCP tools not discovered
Ensure the Edge URL is correct. CrewAI connects lazily when the crew starts. check console output.
Agent not using tools
Make the task description specific. Instead of "do something", say "Use the available tools to list contacts".
Timeout errors
CrewAI has a 10s connection timeout by default. Ensure your network can reach the Edge URL.
Rate limiting or 429 errors
Vinkius enforces per-token rate limits. Check your subscription tier and request quota in the dashboard. Upgrade if you need higher throughput.
