AI agents call analyzeSchema to retrieve information from AWS HealthImaging MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'analyzeSchema' most likely performs schema analysis or inspection, which is a read operation that retrieves and examines structural information without modifying data. While severity is elevated to 'medium' rather than 'low' due to potential exposure of schema details that could inform attacks, the operation itself is non-destructive.
From the tool's definition Tool name 'analyzeSchema' combined with AWS HealthImaging context suggests inspection or examination of schema structure.
Documented attack patterns abuse exactly the kind of access analyzeSchema gives an agent:
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 analyzeSchema:
{
"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.

analyzeSchema. It is categorised as a Read tool in the AWS HealthImaging MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS HealthImaging MCP Server MCP server in PolicyLayer and add a rule for analyzeSchema: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AWS HealthImaging MCP Server. Nothing to install.
analyzeSchema is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the analyzeSchema rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for analyzeSchema. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
analyzeSchema is provided by the AWS HealthImaging MCP Server MCP server (awslabs.healthimaging-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS HealthImaging MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
