overpass.search.named
Search OpenStreetMap for named geographic features — streets, parks, landmarks, rivers, mountains, districts, or any named OSM element — by partial name (case-insensitive). Optionally constrain results to a bounding box. Filter by element type: node (point features like fountains, statues), way (...

What overpass.search.named does on Apibase
AI agents call overpass.search.named to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | string | Yes | Name or partial name to search for (case-insensitive regex). E.g. "Central Park", "Baker Street", "Eiffel". |
limit | integer | — | Maximum number of results to return (1–30, default 10). |
lat_max | number | — | Optional northern boundary latitude to constrain the search area. |
lat_min | number | — | Optional southern boundary latitude to constrain the search area. |
lon_max | number | — | Optional eastern boundary longitude to constrain the search area. |
lon_min | number | — | Optional western boundary longitude to constrain the search area. |
feature_type | string | — | OSM element type to search: "node" (points), "way" (roads/areas), "relation" (complex features), "all" (default). |

Attacks that exploit this kind of access
The rule that runs overpass.search.named safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For overpass.search.named, this is the rule to start with:
overpass.search.named is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Apibase, apply this rule, and every overpass.search.named call is checked against it from then on.
Questions about overpass.search.named
Search OpenStreetMap for named geographic features — streets, parks, landmarks, rivers, mountains, districts, or any named OSM element — by partial name (case-insensitive). Optionally constrain results to a bounding box. Filter by element type: node (point features like fountains, statues), way (roads, paths, area outlines), relation (complex features like national parks, city boundaries), or all. Returns name, coordinates or centroid, place type, and all OSM tags. Useful for locating specific landmarks or verifying a place exists in a region. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
overpass.search.named accepts 7 parameters: name, limit, lat_max, lat_min, lon_max, lon_min, feature_type. Required: name. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for overpass.search.named: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Apibase. Nothing to install.
overpass.search.named is a Read tool with low risk. Read-only tools are generally safe to allow by default.
