Get the TMDL definition of a semantic model with pagination and filtering support.
AI agents call get_model_definition 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 metadata and structural information from a Power BI semantic model. It does not create, modify, delete, execute code, or perform financial transactions. The pagination and filtering are read-only parameters used to control what definition content is returned. Confidence is high because the description is explicit about the retrieval operation with no destructive or executable side effects.
From the tool's definition Tool description states 'Get the TMDL definition of a semantic model with pagination and filtering support.' The verb 'Get' and the read-only nature of retrieving model definitions (TMDL = Tabular Model Definition Language) indicate data retrieval without…

Get the TMDL definition of a semantic model with pagination and filtering support. 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_definition: 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_definition 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_definition 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_definition. 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_definition 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.
