Clear all cached SSH credentials
AI agents call ssh_clear_credentials to permanently remove resources in SSH MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Clearing cached credentials is a destructive, non-reversible action. Once credentials are purged, they cannot be recovered from the cache; any agent or user relying on those cached credentials would lose access, potentially disrupting ongoing SSH sessions or automated workflows.

Clear all cached SSH credentials. It is categorised as a Destructive tool in the SSH MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the SSH MCP Server MCP server in PolicyLayer and add a rule for ssh_clear_credentials: 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.
ssh_clear_credentials is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the ssh_clear_credentials 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 ssh_clear_credentials. 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.
ssh_clear_credentials is provided by the SSH MCP Server MCP server (inframcp/ssh-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
