Use this when you want to find CONTAM project files, result files, or weather files in a directory tree before running a simulation.
AI agents call list_contam_case_files to retrieve information from CONTAM MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from a filesystem directory tree without creating, modifying, executing, or deleting anything. It is a classic Read operation with minimal blast radius—an AI agent misusing it could only enumerate files, not alter system state or trigger simulations.
From the tool's definition Tool name 'list_contam_case_files' and description 'find CONTAM project files, result files, or weather files in a directory tree' indicates a directory listing/search operation with no modification or execution.
Attacks that exploit this kind of access
Use this when you want to find CONTAM project files, result files, or weather files in a directory tree before running a simulation. It is categorised as a Read tool in the CONTAM MCP MCP Server, which means it retrieves data without modifying state.
Register the CONTAM MCP server in PolicyLayer and add a rule for list_contam_case_files: 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 CONTAM MCP. Nothing to install.
list_contam_case_files 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 list_contam_case_files 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 list_contam_case_files. 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.
list_contam_case_files is provided by the CONTAM MCP server (summer521521/contam_plugin). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
