AI agents call read_document to retrieve information from Wps without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves document content with no side effects. It performs a query operation typical of the Read category. The low severity reflects that reading documents poses minimal risk unless the documents contain highly sensitive data, but the tool itself performs no destructive or state-changing operations.
From the tool's definition Tool name is 'read_document' and description states 'Read and return document content.' The verb 'read' and 'return' indicate retrieval without modification.
Attacks that exploit this kind of access
Read and return document content. It is categorised as a Read tool in the Wps MCP Server, which means it retrieves data without modifying state.
Register the Wps MCP server in PolicyLayer and add a rule for read_document: 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 Wps. Nothing to install.
read_document 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 read_document 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 read_document. 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.
read_document is provided by the Wps MCP server (xiao-rx/wps-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
