kb_read_document
AI agents call kb_read_document to retrieve information from TorchV AIS MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though kb_read_document only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
kb_read_document. It is categorised as a Read tool in the TorchV AIS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the TorchV AIS MCP Server MCP server in PolicyLayer and add a rule for kb_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 TorchV AIS MCP Server. Nothing to install.
kb_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 kb_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 kb_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.
kb_read_document is provided by the TorchV AIS MCP Server MCP server (torchv/ais-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
