THE RISK

Low Risk

Why get_bfd_state needs a policy

This tool retrieves monitoring data about BFD session state on SD-WAN devices. It has no capability to modify configurations, execute commands, delete data, or trigger financial transactions. The only risk is potential information disclosure if an agent queries unauthorized devices, but the tool itself performs a read-only operation consistent with network monitoring and diagnostics.

From the tool's definition Tool name 'get_bfd_state' and description 'Get BFD (Bidirectional Forwarding Detection) state for a device' indicate a retrieval operation.

POLICY

How to control get_bfd_state

PolicyLayer is an MCP gateway — it sits between your AI agents and SD-WAN MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_bfd_state:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_bfd_state": {}
  }
}

get_bfd_state is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register SD-WAN MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about get_bfd_state

What does the get_bfd_state tool do? +

Get BFD (Bidirectional Forwarding Detection) state for a device. It is categorised as a Read tool in the SD-WAN MCP Server MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_bfd_state? +

Register the SD-WAN MCP Server MCP server in PolicyLayer and add a rule for get_bfd_state: 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 SD-WAN MCP Server. Nothing to install.

What risk level is get_bfd_state? +

get_bfd_state is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_bfd_state? +

Yes. Add a rate_limit block to the get_bfd_state 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.

How do I block get_bfd_state completely? +

Set action: deny in the PolicyLayer policy for get_bfd_state. 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.

What MCP server provides get_bfd_state? +

get_bfd_state is provided by the SD-WAN MCP Server MCP server (stormbliss/sdwan-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every SD-WAN MCP Server tool call.

Start from SD-WAN MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
