ListCodeConnections
AI agents call ListCodeConnections 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 tool performs a read-only operation to list existing code connections. Although the description is empty, the naming convention strongly suggests this retrieves data with no side effects. The low severity reflects minimal blast radius if misused, as listing connections only exposes metadata rather than enabling destructive or financial operations. Confidence is reduced from higher due to the missing description.
From the tool's definition Tool name 'ListCodeConnections' indicates a read operation that retrieves or enumerates code connections. The 'List' prefix is a common pattern for querying/retrieving data without modification.
Attacks that exploit this kind of access
ListCodeConnections. 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 ListCodeConnections: 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.
ListCodeConnections 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 ListCodeConnections 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 ListCodeConnections. 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.
ListCodeConnections 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.
