Returns a Timestream for InfluxDB DB instance details by the instance-identifier
AI agents call GetDbInstance 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.
This tool performs a read-only operation to fetch configuration and status details of a database instance. It has no side effects, does not execute arbitrary code, and does not modify, delete, or commit financial transactions. The blast radius of misuse is minimal—an agent could gain visibility into database instance configuration but cannot alter infrastructure or cause data loss.
From the tool's definition Tool name 'GetDbInstance' and description 'Returns a Timestream for InfluxDB DB instance details by the instance-identifier' indicate a retrieval operation that queries and returns database instance metadata without modification.
Attacks that exploit this kind of access
Returns a Timestream for InfluxDB DB instance details by the instance-identifier. 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 GetDbInstance: 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.
GetDbInstance 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 GetDbInstance 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 GetDbInstance. 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.
GetDbInstance 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.
