Create a backup of the knowledge base. Backs up database and embeddings to a zip file. Use this regularly for data safety and before making major changes.
AI agents use create_backup to create or update resources in TDZ C64 Knowledge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TDZ C64 Knowledge environment.
Backups are reversible write operations that create copies of data rather than destructively removing it. While backups represent state capture, they do not constitute Read (no query), Execute/Destructive (no code execution or data removal), Financial, or Other categories.
From the tool's definition The tool description states it 'Backs up database and embeddings to a zip file.' Creating a backup is a write operation that generates a new file artifact without modifying or deleting the underlying knowledge base itself.
Attacks that exploit this kind of access
Create a backup of the knowledge base. Backs up database and embeddings to a zip file. Use this regularly for data safety and before making major changes. It is categorised as a Write tool in the TDZ C64 Knowledge MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the TDZ C64 Knowledge MCP server in PolicyLayer and add a rule for create_backup: 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 TDZ C64 Knowledge. Nothing to install.
create_backup is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_backup 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 create_backup. 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.
create_backup is provided by the TDZ C64 Knowledge MCP server (michaeltroelsen/tdz-c64-knowledge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
