WHAT IT DOES

What onemap_route does on Mcp Singapore

AI agents call onemap_route to retrieve information from Mcp Singapore 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
`routeType`	string	—
`endLatitude`	number	Yes
`endLongitude`	number	Yes
`startLatitude`	number	Yes
`startLongitude`	number	Yes

Parameters from the server's own tool schema.

RISK

Why onemap_route is rated Low

Even though onemap_route only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

RECOMMENDED RULE

The rule that runs onemap_route safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Singapore, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For onemap_route, this is the rule to start with:

onemap_route Allowed

onemap_route is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "onemap_route": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Mcp Singapore, apply this rule, and every onemap_route call is checked against it from then on.
