WHAT IT DOES

What arvan_security_generate_ssh_keypair does on ArvanCloud MCP Server

AI agents use arvan_security_generate_ssh_keypair to create or update resources in ArvanCloud MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ArvanCloud MCP Server environment.

RISK

Why arvan_security_generate_ssh_keypair is rated Medium

This tool creates new security credentials (SSH keypairs) that are persisted or returned to the user. While it doesn't directly modify infrastructure, generating credentials represents a reversible write operation that changes the security posture of the platform.

From the tool's definition Tool description states it will 'Generate an SSH keypair' which creates new cryptographic key material that will be stored or returned for use in provisioning.

RECOMMENDED RULE

The rule that runs arvan_security_generate_ssh_keypair safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ArvanCloud MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For arvan_security_generate_ssh_keypair, this is the rule to start with:

arvan_security_generate_ssh_keypair Rate-limited

arvan_security_generate_ssh_keypair stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
