Get a specific SSH key.. Retrieves information about a specific SSH key.
AI agents call mittwald_user_ssh_key_get 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 performs a read operation that queries SSH key metadata without modifying, deleting, or executing anything. The blast radius is minimal—an attacker could learn SSH key details (ID, fingerprint, associated accounts) but cannot compromise the key itself or perform authentication. Classified as Read with low severity.
From the tool's definition Tool name and description indicate retrieval only: 'Get a specific SSH key' and 'Retrieves information about a specific SSH key'. No modification, deletion, or execution is described.

Register the Mittwald MCP Server MCP server in PolicyLayer and add a rule for mittwald_user_ssh_key_get: 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_get 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_get 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_get. 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_get 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.
