Remove/uninstall/delete one or multiple MCP servers from an agent. Use when user wants to remove MCP server capabilities from an existing agent.
AI agents call remove_mcp_server to permanently remove resources in Snak — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes MCP server configurations from an agent, which cannot be undone without manual reconfiguration. While not data destruction in the traditional sense, it removes functional capabilities and configuration state in a way that cannot be automatically restored.
From the tool's definition Tool name contains 'remove' and description explicitly states 'Remove/uninstall/delete one or multiple MCP servers'. The verbs 'remove', 'uninstall', and 'delete' directly indicate irreversible deletion of configured capabilities.

Remove/uninstall/delete one or multiple MCP servers from an agent. Use when user wants to remove MCP server capabilities from an existing agent. It is categorised as a Destructive tool in the Snak MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Snak MCP server in PolicyLayer and add a rule for remove_mcp_server: 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 Snak. Nothing to install.
remove_mcp_server 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 remove_mcp_server 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 remove_mcp_server. 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.
remove_mcp_server is provided by the Snak MCP server (kasarlabs/snak). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
