Monitor documents for structural drift over time. Actions:
AI agents call drift-monitor to retrieve information from MCP Document Processor without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The drift-monitor tool performs observation and analysis of document structure changes without creating, modifying, deleting, or executing code. It retrieves and compares document state over time, making it a Read category tool.
From the tool's definition Tool description states it 'Monitor[s] documents for structural drift over time' - monitoring and observing are read-only activities with no modification or execution of external operations implied.
Attacks that exploit this kind of access
Monitor documents for structural drift over time. Actions:. It is categorised as a Read tool in the MCP Document Processor MCP Server, which means it retrieves data without modifying state.
Register the MCP Document Processor MCP server in PolicyLayer and add a rule for drift-monitor: 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 MCP Document Processor. Nothing to install.
drift-monitor is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the drift-monitor 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 drift-monitor. 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.
drift-monitor is provided by the MCP Document Processor MCP server (leanzero-srl/leanzero-mcp-doc-processor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
