Why bitmap_pos needs a policy

The tool name 'bitmap_pos' does not clearly map to any ECS or AWS operation, and the description is empty. It appears out of place among ECS/AWS deployment tools. Without any description, classification is highly uncertain. Defaulting to Other with very low confidence.

From the tool's definition Tool name 'bitmap_pos' and empty description provide no clear indication of what this tool does in the context of an ECS MCP server.

POLICY

How to control bitmap_pos

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bitmap_pos": {
      "limits": [
        {
          "counter": "bitmap_pos_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

bitmap_pos gets a rate cap, and everything else on the server is denied unless you say otherwise.

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