Get details of a specific VRF
AI agents call get_vrf to retrieve information from ACI 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 information about a Virtual Routing and Forwarding (VRF) instance in Cisco ACI. It performs no side effects—it does not create, modify, delete, or execute operations. The action is purely informational query, fitting the Read category.
From the tool's definition Tool name 'get_vrf' and description 'Get details of a specific VRF' indicate data retrieval with the verb 'Get', which is a read-only operation that queries existing VRF configuration without modification or deletion.
Attacks that exploit this kind of access
Get details of a specific VRF. It is categorised as a Read tool in the ACI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the ACI MCP Server MCP server in PolicyLayer and add a rule for get_vrf: 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 ACI MCP Server. Nothing to install.
get_vrf 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_vrf 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_vrf. 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_vrf is provided by the ACI MCP Server MCP server (jim-coyne/aci_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
