List all computers with optional filtering
AI agents call list_computers to retrieve information from BeyondTrust EPM MCP Server 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 information about computers in the BeyondTrust EPM system without creating, modifying, deleting, or executing any operations. The 'list' and 'filtering' language clearly indicates a read-only function. While the list of computers could inform threat modeling, disclosure alone creates minimal risk absent further action through other tools.
From the tool's definition Tool name 'list_computers' and description 'List all computers with optional filtering' indicate a data retrieval operation with no side effects.
Attacks that exploit this kind of access
List all computers with optional filtering. It is categorised as a Read tool in the BeyondTrust EPM MCP Server MCP Server, which means it retrieves data without modifying state.
Register the BeyondTrust EPM MCP Server MCP server in PolicyLayer and add a rule for list_computers: 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 BeyondTrust EPM MCP Server. Nothing to install.
list_computers 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_computers 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_computers. 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_computers is provided by the BeyondTrust EPM MCP Server MCP server (wesharris222/btepmmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
