Update tags for multiple documents in bulk. Add, remove, or replace tags for documents selected by ID or existing tags. Useful for reorganizing and categorizing the knowledge base.
AI agents use update_tags_bulk 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.
This tool modifies document tags (metadata) in the knowledge base but does not delete documents, execute arbitrary code, or access financial systems. Tag updates are reversible write operations. The bulk nature affects scale but not severity category.
From the tool's definition Tool description states it will "Update tags for multiple documents in bulk. Add, remove, or replace tags" - these are reversible modification operations on metadata.
Attacks that exploit this kind of access
Update tags for multiple documents in bulk. Add, remove, or replace tags for documents selected by ID or existing tags. Useful for reorganizing and categorizing the knowledge base. 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 update_tags_bulk: 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.
update_tags_bulk 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 update_tags_bulk 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 update_tags_bulk. 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.
update_tags_bulk 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.
