THE RISK

Low Risk

Why dsql_lint needs a policy

The description is empty, so the true behavior is unknown. The name suggests a linting or static analysis operation, which would typically be a read-only analysis with no side effects. However, without confirmation, confidence is low. Lint tools generally do not modify, delete, or execute data, placing this in 'Read' or 'Other'. Given the ambiguity, 'Other' with low confidence is appropriate.

From the tool's definition Tool description is empty; name 'dsql_lint' suggests linting/static analysis of DSQL (possibly SQL-like queries)

POLICY

How to control dsql_lint

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

policy.json

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

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

Create a free account and register AWS HealthImaging 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.
