What the publisher says

From the Openstreetmap repository's README, as published. We do not edit it. Read it on GitHub

@cyanheads/openstreetmap-mcp-server Geocode, reverse geocode, and run Overpass spatial queries on OpenStreetMap data via MCP. STDIO or Streamable HTTP. 6 Tools

Public Hosted Server: https://openstreetmap.caseyjhand.com/mcp

Overview

Geocoding, reverse geocoding, and spatial queries over OpenStreetMap data via Nominatim and the Overpass API. Search places, resolve coordinates to addresses, and query nearby or bounded features by tag from any MCP client. Runs as a stdio process, a local Streamable HTTP server, or the public hosted endpoint above.

Is Openstreetmap MCP server safe?: Yes, by our scan: it is graded A (86/100). Read the Openstreetmap safety report
How do I install Openstreetmap?: It runs remotely at openstreetmap.caseyjhand.com. Add it to Claude Code, Cursor, VS Code or Claude Desktop with the snippets above, or call it through the mcp.market gateway without installing anything.
Does Openstreetmap need an API key?: No secret keys are declared. It reads 18 settings from the environment.
Is Openstreetmap maintained?: The last commit was 43 days ago (2026-09-22). The latest release is v0.7.0.
Is Openstreetmap up?: 100% of our last 28 checks got an answer. We check remote servers about four times a day.
How does Openstreetmap compare with other MCP servers?: safety score 86/100 (higher than 72% of 48,255 servers); uptime 100% (of our recent checks; the typical remote server answers 100%); response time 493 ms (faster than 30% of 30,031 servers). Full comparison.

Run it through the gateway

With the gateway added, ask your agent for it by name:

Credentials it needs

OSM_NOMINATIM_BASE_URLNominatim API base URL. Override to use a private or mirror instance.
OSM_USER_AGENTUser-Agent sent to Nominatim and Overpass. Required by usage policy.
OSM_OVERPASS_BASE_URLOverpass API endpoint URL. When set, pins every query to this one endpoint and disables mirror failover; OSM_OVERPASS_MAX_CONCURRENCY sizes it and a |N suffix is rejected. Leave unset to use OSM_OVERPASS_ENDPOINTS.
OSM_OVERPASS_ENDPOINTSComma-separated ordered list of Overpass endpoints. A failure advances to the next entry within the same tool call; a single entry means no failover. An entry written url|N gets N slots of its own and adds capacity, for an instance whose operator allows parallel queries, never a public FOSSGIS server; an unsuffixed later entry is failover only. Write a | inside a URL as %7C. Verify a mirror's usage policy, data coverage, and freshness before adding it. Ignored when OSM_OVERPASS_BASE_URL is set.
OSM_OVERPASS_MAX_CONCURRENCYConcurrent Overpass queries per endpoint: OSM_OVERPASS_BASE_URL, and every OSM_OVERPASS_ENDPOINTS entry not sized with |N. With no |N entry it is also the most queries in flight across all endpoints. A query waits at most 30 seconds in total for a slot, then fails with pacer_shed and a retryAfter. The default of 1 follows the public FOSSGIS instances, which allow one query in flight per user; raise it only for an instance whose operator allows parallel queries, such as a private or paid one.
MCP_LOG_LEVELSets the minimum log level for output (e.g., 'debug', 'info', 'warn').
MCP_TRANSPORT_TYPESelects the HTTP transport.
MCP_HTTP_HOSTThe hostname for the HTTP server.
MCP_HTTP_PORTThe port to run the HTTP server on.
MCP_HTTP_ENDPOINT_PATHThe endpoint path for the MCP server.
MCP_PUBLIC_URLPublic origin override for deployments behind a TLS-terminating reverse proxy (e.g. https://mcp.example.com).
MCP_AUTH_MODEAuthentication mode to use: 'none', 'jwt', or 'oauth'.
OSM_NOMINATIM_BASE_URLNominatim API base URL. Override to use a private or mirror instance.
OSM_USER_AGENTUser-Agent sent to Nominatim and Overpass. Required by usage policy.
OSM_OVERPASS_BASE_URLOverpass API endpoint URL. When set, pins every query to this one endpoint and disables mirror failover; OSM_OVERPASS_MAX_CONCURRENCY sizes it and a |N suffix is rejected. Leave unset to use OSM_OVERPASS_ENDPOINTS.
OSM_OVERPASS_ENDPOINTSComma-separated ordered list of Overpass endpoints. A failure advances to the next entry within the same tool call; a single entry means no failover. An entry written url|N gets N slots of its own and adds capacity, for an instance whose operator allows parallel queries, never a public FOSSGIS server; an unsuffixed later entry is failover only. Write a | inside a URL as %7C. Verify a mirror's usage policy, data coverage, and freshness before adding it. Ignored when OSM_OVERPASS_BASE_URL is set.
