AI agents call get_case 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 retrieves case information by ID without altering any data. It is a simple read-only query operation consistent with the Read category (retrieve or query data; no side effects). The blast radius of misuse is minimal—an attacker could access sensitive case information but cannot modify, delete, or trigger external actions.
From the tool's definition Tool name is 'get_case' and description states 'Get a case by ID' — a retrieval operation with no modification or side effects.
Attacks that exploit this kind of access
Get a case by ID. 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 get_case: 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.
get_case 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 get_case 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 get_case. 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.
get_case 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.
