Display all M Parameters values.
AI agents call get_m_parameters 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 and displays parameter values from Power Query (M language) in a Power BI file. It performs a read-only query operation with no ability to modify, delete, or execute code. The blast radius of misuse is minimal — an AI agent could only access metadata about parameters already defined in the file, which is non-sensitive configuration information.
From the tool's definition Tool name is 'get_m_parameters' and description states 'Display all M Parameters values' — a retrieval operation with no side effects.
Attacks that exploit this kind of access
Display all M Parameters values. 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_m_parameters: 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_m_parameters 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_m_parameters 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_m_parameters. 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_m_parameters 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.
