Why tak_calculate_distance needs a policy

This tool performs a read-only calculation on existing geospatial data. It computes distances between points without creating, modifying, deleting, or executing any external operations. The operation has no side effects and returns computed results only. Even in a misuse scenario, an AI agent could at worst learn distances between entities, which poses minimal risk.

From the tool's definition Tool name 'tak_calculate_distance' and description 'Calculate distances between entities, points, or coordinates' indicate a pure computation/query operation that retrieves or calculates geospatial data without modifying, deleting, or executing external…

POLICY

How to control tak_calculate_distance

PolicyLayer is an MCP gateway — it sits between your AI agents and TAK Server MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for tak_calculate_distance:

policy.json

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

tak_calculate_distance is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register TAK Server MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about tak_calculate_distance

What does the tak_calculate_distance tool do? +

Calculate distances between entities, points, or coordinates. It is categorised as a Read tool in the TAK Server MCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on tak_calculate_distance? +

Register the TAK Server MCP server in PolicyLayer and add a rule for tak_calculate_distance: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches TAK Server MCP. Nothing to install.

What risk level is tak_calculate_distance? +

tak_calculate_distance is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit tak_calculate_distance? +

Yes. Add a rate_limit block to the tak_calculate_distance rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block tak_calculate_distance completely? +

Set action: deny in the PolicyLayer policy for tak_calculate_distance. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides tak_calculate_distance? +

tak_calculate_distance is provided by the TAK Server MCP server (jfuginay/tak-server-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every TAK Server MCP tool call.

Start from TAK Server MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
