listDatabases
AI agents call listDatabases to retrieve information from AWS IoT SiteWise MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The name 'listDatabases' strongly suggests a retrieval operation that queries available databases without side effects. This fits the Read category pattern (list, get, fetch). No modification, execution, deletion, or financial operation is implied. Confidence is moderately high based on naming convention, but the empty description prevents higher confidence.
From the tool's definition Tool name 'listDatabases' indicates a query/listing operation typical of Read category. AWS IoT SiteWise contexts support this interpretation—listing databases retrieves information without modification.
Attacks that exploit this kind of access
listDatabases. It is categorised as a Read tool in the AWS IoT SiteWise MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS IoT SiteWise MCP Server MCP server in PolicyLayer and add a rule for listDatabases: 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 IoT SiteWise MCP Server. Nothing to install.
listDatabases 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 listDatabases 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 listDatabases. 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.
listDatabases is provided by the AWS IoT SiteWise MCP Server MCP server (awslabs.aws-iot-sitewise-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
