analyzeSchema · AWS Labs MySQL MCP Server MCP: Risk & Policy

WHAT IT DOES

What analyzeSchema does on AWS Labs MySQL MCP Server

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

THE RISK

Low Risk

Why analyzeSchema needs a policy

Schema analysis is typically a read-only operation that examines database metadata without modifying or executing code. No side effects are implied by the name alone. Confidence is reduced to 0.6 due to lack of descriptive detail; if the tool performs unexpected schema modifications or executes arbitrary queries, this classification would need revision.

From the tool's definition Tool name 'analyzeSchema' suggests inspection/analysis of database schema structure. Description is empty, limiting certainty.

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

POLICY

How to control analyzeSchema

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

policy.json

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

analyzeSchema 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 AWS Labs MySQL 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.
