List all departments in the practice
AI agents call list_departments to retrieve information from athenahealth 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 and displays a list of departments—a read-only query operation with no side effects, no data modification, no code execution, and no financial impact. The blast radius of misuse is minimal; an attacker gaining access would obtain department names only, which are typically non-sensitive organizational metadata.
From the tool's definition Tool name 'list_departments' and description 'List all departments in the practice' indicate a retrieval operation that queries organizational data without modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
List all departments in the practice. It is categorised as a Read tool in the athenahealth MCP Server MCP Server, which means it retrieves data without modifying state.
Register the athenahealth MCP Server MCP server in PolicyLayer and add a rule for list_departments: 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 athenahealth MCP Server. Nothing to install.
list_departments 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_departments 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_departments. 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_departments is provided by the athenahealth MCP Server MCP server (ophydami/athenahealth-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
