THE RISK

Why bcm-pricing-calc needs a policy

The tool name suggests it may be related to AWS Billing and Cost Management (BCM) pricing calculations, which could have financial implications. However, the description is completely empty, making it impossible to determine the exact behavior. Given the naming convention and context of an AWS DynamoDB MCP server, this might be a pricing estimation tool (Read), but without confirmation, confidence is very low.

From the tool's definition Tool name 'bcm-pricing-calc' and empty description provide insufficient information to determine what this tool does.

POLICY

How to control bcm-pricing-calc

PolicyLayer is an MCP gateway — it sits between your AI agents and AWS DynamoDB MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for bcm-pricing-calc:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "bcm-pricing-calc": {
      "limits": [
        {
          "counter": "bcm-pricing-calc_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

bcm-pricing-calc gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register AWS DynamoDB 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.
