# 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.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "overpass.search.named",
    "arguments": {
      "name": "<name>"
    }
  }
}
```

## Why overpass.search.named is rated Low

Tool queries public geographic data without modifying, executing commands, or financial effects.

From the tool's own definition: "Search OpenStreetMap for named geographic features by partial name, returns coordinates and tags"

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "overpass.search.named": {}
  }
}
```
