Part of the Better Bear MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
AI agents may call bear_context_remove_external to permanently remove or destroy resources in Better Bear. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. Intercept blocks destructive tools by default and requires explicit human approval before enabling them.
Without a policy, an AI agent could call bear_context_remove_external in a loop, permanently destroying resources in Better Bear. There is no undo for destructive operations. Intercept blocks this tool by default and only allows it when a human explicitly approves the action.
