What bitmap_get does on Amazon Location Service MCP Server

AI agents call bitmap_get to retrieve information from Amazon Location Service MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Why bitmap_get needs a policy

The 'get' operation with 'bit value at offset' is a read-only query that retrieves existing data. There is no creation, modification, deletion, or execution of external operations. The blast radius of misuse is minimal—an agent could only retrieve bitmap values, not alter them or trigger consequential actions.

From the tool's definition Tool name 'bitmap_get' and description 'Get the bit value at offset' indicate a retrieval operation that accesses data without modification or side effects.

Documented attack patterns abuse exactly the kind of access bitmap_get gives an agent:

How to control bitmap_get

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "bitmap_get": {}
  }
}

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

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