Geocoding, static maps and privacy-safe area maps from OpenStreetMap data. Hard caps, no overage.

Anlyon alternative

3 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.

- The description's first verb is "show": a word for reading.
- The description says "cannot be recovered".
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

  What this check looks for
Description, as the server wrote it
Show roughly where a place is without revealing the exact point. The point is snapped to a grid and drawn as a shaded circle that always contains the true point, with no pin; every address in the same grid cell gets the identical image, so the exact location cannot be recovered or averaged out across listings. Use it for real-estate, rental and marketplace listings, people's homes, or any location that should stay private. The image is returned inline, with a reusable URL that contains only the snapped point. Counts 1 static image against the account's monthly cap.
Annotations the server declares

- idempotentHint: true
- openWorldHint: false
- readOnlyHint: true
- title: Map an approximate area without revealing the exact point

geocodeLook up an address, place name or point of interest and get coordinates (lat, lon), a readable label and address parts, from OpenStreetMap data.No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Look up an address, place name or point of interest and get coordinates (lat, lon), a readable label and address parts, from OpenStreetMap data. Use it before static_map or privacy_area_map when you only have an address. Counts 1 address lookup against the account's monthly cap. Results may be stored: up to 30 days on the Free plan, indefinitely on paid plans. Show "© OpenStreetMap contributors" with results.
Annotations the server declares

- idempotentHint: true
- openWorldHint: false

Why it is in this group

- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it
Render a map as an image (returned inline) with optional pins (markers) and a line (path, e.g. a route). Give center and zoom, or just markers and/or path and the view is fitted automatically. Also returns a reusable image URL for web pages (add your key). Counts 1 static image against the account's monthly cap. Do not use this to show a private address such as someone's home; use privacy_area_map instead.

Why it is in this group
- The description's first verb is "get": a word for reading.
What it can reach
- untrusted-inputThe description's first sentence says "get" and "html": it reads web pages, which anyone can write.
Description, as the server wrote it
Get ready-to-paste HTML/JavaScript for an interactive, zoomable PinSharing map in a web page (MapLibre GL JS vector map, Leaflet or OpenLayers raster map), or the raster tile URL template for any other library. Replace YOUR_KEY with a key restricted to the website. Needs no key and uses no quota; the map itself counts map tiles when viewed.

Why it is in this group
- The description's first verb is "find": a word for reading.
Description, as the server wrote it
Find the nearest address or place to a latitude/longitude, from OpenStreetMap data. Counts 1 address lookup against the account's monthly cap. Same storage terms and attribution as geocode.

- openWorldHint: false
- readOnlyHint: true
- title: Find the address at a point

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

Exfil surface

Which tools read private data, which read text someone else can write, and which can send data out. One of each is a path a prompt injection can use.

No private-data, untrusted-input, outbound path in this server alone: no tool is tagged private-data or outbound.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write1: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; map_setup
Can send data out0: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.

Other servers in the same agent add their own tools to these paths. Audit your whole setup to see them together.

Findings

Matches of fixed checks, with the text they matched.

No change seen yet. Its tools are rescanned every day, and a remote endpoint is looked at once a week.

Claude Code permissions

Allow the reads, ask before a change or a way out, deny the deletes. Paste into .claude/settings.json.

.claude/settings.json

{
  "permissions": {
    "allow": [
      "mcp__maps__reverse_geocode",
      "mcp__maps__map_setup"

      "mcp__maps__privacy_area_map"
    ],
    "deny": []
  }
}

Tools that only read are allowed, tools that change things ask first, tools that delete or cancel are denied. A read that can send data out (it takes a URL, say) asks first too. It assumes the server is installed as maps. Review it before you use it.
