Clear all facts, rules, and predicates from the knowledge base.
AI agents call clear_program to permanently remove resources in Pyke MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs an irreversible deletion of all knowledge base contents. While the data could theoretically be reloaded, the tool itself does not undo or recover — it permanently clears the state.
From the tool's definition The tool description states it will "Clear all facts, rules, and predicates from the knowledge base" — this irreversibly removes all data from the knowledge base without the ability to recover it.

Attacks that exploit this kind of access
Clear all facts, rules, and predicates from the knowledge base. It is categorised as a Destructive tool in the Pyke MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Pyke MCP Server MCP server in PolicyLayer and add a rule for clear_program: 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 Pyke MCP Server. Nothing to install.
clear_program 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 clear_program 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 clear_program. 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.
clear_program is provided by the Pyke MCP Server MCP server (newjerseystyle/pyke-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
