AI agents call list_case_stages to retrieve information from Mycase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns configuration data about case stages. It performs no modifications, deletions, code execution, or financial transactions. It is purely informational retrieval, fitting the Read category. The severity is low because case stage metadata is non-sensitive operational configuration with minimal impact if disclosed or accessed by an unauthorized agent.
From the tool's definition Tool name 'list_case_stages' and description 'List all case stages configured in this firm' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List all case stages configured in this firm. It is categorised as a Read tool in the Mycase MCP Server, which means it retrieves data without modifying state.
Register the Mycase MCP server in PolicyLayer and add a rule for list_case_stages: 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 Mycase. Nothing to install.
list_case_stages 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_case_stages 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_case_stages. 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_case_stages is provided by the Mycase MCP server (rosenadvertising/mycase-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
