AI agents invoke send_command_and_get_output to trigger actions in Mcp Netmiko. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The tool name strongly implies sending a command to a network device and retrieving output. Given the server context (SSH-based network device interaction with netmiko), this tool almost certainly executes commands on routers/switches. While it may be primarily used for read-only 'show' commands, the ability to send arbitrary commands to network devices via SSH represents Execute-level risk.
From the tool's definition Tool name 'send_command_and_get_output' combined with server description: 'Enables LLMs to interact with network devices via SSH (netmiko), allowing command execution and configuration changes on routers and switches.'
Documented attack patterns abuse exactly the kind of access send_command_and_get_output gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Mcp Netmiko, and nothing reaches the server without passing your rules. This is the rule we recommend for send_command_and_get_output:
{
"version": "1",
"default": "deny",
"tools": {
"send_command_and_get_output": {
"limits": [
{
"counter": "send_command_and_get_output_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}send_command_and_get_output stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

send_command_and_get_output. It is categorised as a Execute tool in the Mcp Netmiko MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Mcp Netmiko MCP server in PolicyLayer and add a rule for send_command_and_get_output: 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 Mcp Netmiko. Nothing to install.
send_command_and_get_output is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the send_command_and_get_output 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 send_command_and_get_output. 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.
send_command_and_get_output is provided by the Mcp Netmiko MCP server (upa/mcp-netmiko-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
