Get your stored SSH keys.. Lists all SSH keys for the current user.
AI agents call mittwald_user_ssh_key_list to retrieve information from Mittwald MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists existing SSH keys belonging to the user. It is a read-only operation that queries data without creating, modifying, deleting, or executing anything. While SSH keys are sensitive, the tool itself only exposes their list/metadata, not their private key material. The blast radius of an AI misusing this is limited to information disclosure about which SSH keys the user has stored.
From the tool's definition Tool description states 'Get your stored SSH keys' and 'Lists all SSH keys for the current user' — a pure query/retrieval operation with no modification or execution.
Attacks that exploit this kind of access
Get your stored SSH keys.. Lists all SSH keys for the current user. It is categorised as a Read tool in the Mittwald MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Mittwald MCP Server MCP server in PolicyLayer and add a rule for mittwald_user_ssh_key_list: 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 Mittwald MCP Server. Nothing to install.
mittwald_user_ssh_key_list is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the mittwald_user_ssh_key_list 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 mittwald_user_ssh_key_list. 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.
mittwald_user_ssh_key_list is provided by the Mittwald MCP Server MCP server (mittwald/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
