# GOOGLESUPER_DISTANCE_MATRIX_API

DEPRECATED: Legacy API that calculates travel distance and time for a matrix of origins and destinations. This API only works with API keys (no OAuth2 support). Use the modern 'Compute Route Matrix' action instead, which supports OAuth2 authentication. Supports different modes of transportation and options like departure/arrival times.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `key` | string | no | Your application's API key. This key identifies your application for purposes of quota management. |
| `mode` | string | no | Specifies the mode of transport to use. |
| `avoid` | string | no | Indicates that the calculated route should avoid the specified features. Multiple values can be pipe-separated e.g. 'tolls\|highways'. |
| `units` | string | no | Specifies the unit system to use when displaying results. The default is metric. |
| `region` | string | no | The region code, specified as a ccTLD ('top-level domain') two-character value. This helps influence results based on the region. |
| `origins` | string | no | The starting point for calculating travel distance and time. You can supply one or more locations separated by the pipe character (\|), in the form of a place ID |
| `language` | string | no | The language in which to return results. See the list of supported languages: https://developers.google.com/maps/faq#languagesupport |
| `arrival_time` | integer | no | Specifies the desired time of arrival for transit directions, in seconds since midnight, January 1, 1970 UTC. You can specify either departure_time or arrival_t |
| `destinations` | string | no | One or more locations to use as the finishing point for calculating travel distance and time. Accepts the same formats as origins. |
| `transit_mode` | string | no | Specifies one or more preferred modes of transit. This parameter may only be specified for transit directions. Multiple values can be pipe-separated e.g. 'bus\|t |
| `traffic_model` | string | no | Specifies the assumptions to use when calculating time in traffic. This parameter is only used if the request includes a departure_time and mode is 'driving'. |
| `departure_time` | integer | no | Specifies the desired time of departure. You can specify the time as an integer in seconds since midnight, January 1, 1970 UTC, or as the string 'now'. Required |

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "GOOGLESUPER_DISTANCE_MATRIX_API",
    "arguments": {}
  }
}
```

## Why GOOGLESUPER_DISTANCE_MATRIX_API is rated Low

GOOGLESUPER_DISTANCE_MATRIX_API is a read-only tool that queries travel metrics between locations. It retrieves pre-computed distance and time information based on input parameters (origins, destinations, transportation mode). There are no side effects, no data modification, no code execution, and no financial transactions.

From the tool's own definition: "Tool 'calculates travel distance and time' with support for 'different modes of transportation and options like departure/arrival times' — these are query operations that retrieve routing/distance data without modifying state or executing arbitrary code."

Risk signals: High parameter count (13 properties)

## Use case

AI agents call GOOGLESUPER_DISTANCE_MATRIX_API to retrieve information from Google Super 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 Google Super:

```json
