search_tags
AI agents call search_tags to retrieve information from Docker Explorer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Docker tag search is a non-destructive query operation that retrieves metadata about available image versions. It has no capability to modify, execute, or delete resources. The low severity reflects minimal blast radius—even if an AI agent searches tags maliciously, no data is harmed or moved.
From the tool's definition Tool name 'search_tags' indicates querying/listing Docker image tags; sibling tools like 'search_images', 'get_image_details', and 'scan_security' are all Read category operations.
Attacks that exploit this kind of access
search_tags. It is categorised as a Read tool in the Docker Explorer MCP Server, which means it retrieves data without modifying state.
Register the Docker Explorer MCP server in PolicyLayer and add a rule for search_tags: 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 Explorer. Nothing to install.
search_tags 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 search_tags 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 search_tags. 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.
search_tags is provided by the Docker Explorer MCP server (jar285/mcp-docker). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
