Merge multiple Google Maps directions links into one, bypassing the 10-stop limit.

2 tools: 1 do something that can't be undone and 1 change things.

Anlyon alternative

2 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.

Tools

Grouped by what each tool does, most consequential first. Open one for its reasons and full description; descriptions are the publisher's own words.

2 tools

Can't be undone 1Sends, pays, publishes or merges: once done, it cannot be taken back.Claude Code: ask

combine_map_linksMerge several Google Maps directions links into one link with all stops in order, to get past the 10-stop limit per route.Reads text others writeCan send data out1 finding
Why it is in this group
- The name "combine_map_links" says "link": a word for a change.
- The description's first verb is "merge": a word for a change that another call does not undo.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- outboundThe input takes a URL (input.urls): a request to a URL can carry data to whoever runs it.
Findings
- Warn
  The server marks "combine_map_links" read-only (readOnlyHint: true), and its own name, description or input give the class "irreversible".
  Matched text
  annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "combine_map_links" says "link": a word for a change.
  What this check looks for
Description, as the server wrote it
Merge several Google Maps directions links into one link with all stops in order, to get past the 10-stop limit per route. Short links are expanded. When one route ends where the next starts, the shared stop is kept once.
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true

Changes things 1Creates or changes something that can be changed back.Claude Code: ask

list_link_stopsThe stops of one Google Maps directions link, in order, as MapCombiner reads them.Reads text others writeCan send data out1 finding
Why it is in this group
- The name "list_link_stops" says "list": a word for reading.
- The description's first verb is "stop": a word for a change.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
What it can reach
- untrusted-inputThe server marks it openWorldHint: true: it reaches things outside the server's own data.
- untrusted-inputThe input takes a URL (input.url), and the tool reads it: it reads web pages, which anyone can write.
- outboundThe input takes a URL (input.url): a request to a URL can carry data to whoever runs it.
Findings
- Warn
  The server marks "list_link_stops" read-only (readOnlyHint: true), and its own name, description or input give the class "write".
  Matched text
  annotations: {"readOnlyHint":true,"openWorldHint":true}; The name "list_link_stops" says "list": a word for reading.
  What this check looks for
Description, as the server wrote it
The stops of one Google Maps directions link, in order, as MapCombiner reads them. Use it to check links before combining. For coordinates, distances or CSV/KML export, use MapParser (parseUrl).
Annotations the server declares
- readOnlyHint: true
- openWorldHint: true

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.

Reads private data0: Reads files, mail, messages, databases, secrets, calendars or repositories.
Reads text others write2: Brings in text someone else can write: web pages, inbound email, messages, issues and comments.; combine_map_links
list_link_stops
Can send data out2: Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL.; combine_map_links
list_link_stops

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.

History

Changes to its tool definitions and to its remote endpoint, newest first.

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

Run in a terminal.

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": [],
    "ask": [
      "mcp__map-combiner__combine_map_links",
      "mcp__map-combiner__list_link_stops"
    ],
    "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 map-combiner. Review it before you use it.
