Fetch logs for a Docker container
AI agents call fetch_container_logs to retrieve information from Docker MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical log data from a container without creating, modifying, deleting, or executing operations. While logs may contain sensitive information, accessing them is a standard read operation with minimal blast radius compared to container manipulation or execution. The tool poses no risk of unintended side effects on container state or infrastructure.
From the tool's definition Tool name 'fetch_container_logs' and description 'Fetch logs for a Docker container' indicate log retrieval with no modification. The verb 'fetch' and absence of terms like 'delete', 'modify', 'execute', or 'create' confirm read-only semantics.
Attacks that exploit this kind of access
Fetch logs for a Docker container. It is categorised as a Read tool in the Docker MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Docker MCP Server MCP server in PolicyLayer and add a rule for fetch_container_logs: 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 Docker MCP Server. Nothing to install.
fetch_container_logs 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 fetch_container_logs 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 fetch_container_logs. 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.
fetch_container_logs is provided by the Docker MCP Server MCP server (pnmice/mcp-server-docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
