create_connection · SSH MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_connection does on SSH MCP Server

AI agents invoke create_connection to trigger actions in SSH MCP Server. 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.

WHY IT NEEDS A POLICY

Why create_connection needs a policy

Creating an SSH connection is not merely storing data (Write); it establishes an active network session to a remote system, which is an external operation with real side effects. It enables all subsequent Execute/Destructive operations on remote machines.

From the tool's definition 'Open an SSH session to the given machine and track it in global state so subsequent tool calls can reuse it' — establishes live SSH connectivity to remote systems, enabling all subsequent command execution

Verdict

create_connection Rate-limited

create_connection 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches SSH MCP Server, so you can run agents against it safely.

FAQ

Questions about create_connection

What does the create_connection tool do? +

Open an SSH session to the given machine and track it in global state so subsequent tool calls can reuse it. It is categorised as a Execute tool in the SSH MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on create_connection? +

Register the SSH MCP Server MCP server in PolicyLayer and add a rule for create_connection: 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 SSH MCP Server. Nothing to install.

What risk level is create_connection? +

create_connection is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit create_connection? +

Yes. Add a rate_limit block to the create_connection 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 create_connection completely? +

Set action: deny in the PolicyLayer policy for create_connection. 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 create_connection? +

create_connection is provided by the SSH MCP Server MCP server (vilasone455/ssh-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
