Validate TMDL syntax in the loaded PBIP project. Checks for unquoted names with spaces, invalid references, etc.
AI agents call pbip_validate to retrieve information from Power BI MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
pbip_validate analyzes and reports on syntax errors without making any changes to the PBIP project. It retrieves information about potential issues in the model definition but has no side effects. This is a read-only diagnostic tool with minimal risk if misused by an AI agent.
From the tool's definition Tool performs validation checks on TMDL syntax (checking for unquoted names with spaces, invalid references). Validation is a read-only inspection operation that does not modify, delete, or execute any data or code.
Attacks that exploit this kind of access
Validate TMDL syntax in the loaded PBIP project. Checks for unquoted names with spaces, invalid references, etc. It is categorised as a Read tool in the Power BI MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Power BI MCP Server MCP server in PolicyLayer and add a rule for pbip_validate: 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 Power BI MCP Server. Nothing to install.
pbip_validate 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 pbip_validate 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 pbip_validate. 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.
pbip_validate is provided by the Power BI MCP Server MCP server (sulaiman013/powerbi-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
