AI agents call get_relationships to retrieve information from Pbixray without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves relationship metadata from PowerBI models, which is a read-only query operation with no side effects. The description is empty, but the naming convention and context of sibling tools strongly indicate it queries model structure rather than modifying or executing operations. Confidence is slightly reduced due to missing description, but the category is clear.
From the tool's definition Tool name 'get_relationships' and sibling tools (get_dax_columns, get_dax_measures, get_dax_tables, get_metadata, get_schema, get_statistics) all follow read-only metadata query patterns.
Documented attack patterns abuse exactly the kind of access get_relationships gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Pbixray, and nothing reaches the server without passing your rules. This is the rule we recommend for get_relationships:
{
"version": "1",
"default": "deny",
"tools": {
"get_relationships": {}
}
}get_relationships is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

get_relationships. It is categorised as a Read tool in the Pbixray MCP Server, which means it retrieves data without modifying state.
Register the Pbixray MCP server in PolicyLayer and add a rule for get_relationships: 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. Nothing to install.
get_relationships 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_relationships 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_relationships. 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_relationships is provided by the Pbixray MCP server (jonaolden/pbixray-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Pbixray, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
