Get the model size in bytes.
AI agents call get_model_size to retrieve information from PBIXRay MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational metadata (model size) from an already-connected Power BI file. It performs no data modification, code execution, deletion, or financial operations. The returned size information is non-sensitive and has no side effects. Classification as Read is appropriate; severity is low because model size is technical metadata with minimal security impact if exposed to an LLM.
From the tool's definition Tool name 'get_model_size' and description 'Get the model size in bytes' indicate a retrieval operation that queries metadata about a Power BI model without modification or execution of code.
Attacks that exploit this kind of access
Get the model size in bytes. It is categorised as a Read tool in the PBIXRay MCP Server MCP Server, which means it retrieves data without modifying state.
Register the PBIXRay MCP Server MCP server in PolicyLayer and add a rule for get_model_size: 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 PBIXRay MCP Server. Nothing to install.
get_model_size 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 get_model_size 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 get_model_size. 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.
get_model_size is provided by the PBIXRay MCP Server MCP server (ngoc0610/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
get_model_size is one line of PBIXRay MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
