List all registered MCP servers
AI agents call get_mcp_servers to retrieve information from MCP Automation Service without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about registered MCP servers without modifying, executing, or deleting anything. It is a straightforward read operation with minimal blast radius even if misused by an agent, as it only exposes the list of available servers.
From the tool's definition Tool name is 'get_mcp_servers' and description states 'List all registered MCP servers' — a query operation with no side effects.

List all registered MCP servers. It is categorised as a Read tool in the MCP Automation Service MCP Server, which means it retrieves data without modifying state.
Register the MCP Automation Service MCP server in PolicyLayer and add a rule for get_mcp_servers: 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 MCP Automation Service. Nothing to install.
get_mcp_servers 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 get_mcp_servers 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 get_mcp_servers. 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.
get_mcp_servers is provided by the MCP Automation Service MCP server (shukurlukerem/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
