List semantic models

list_semantic_models

List semantic models from your Power BI workspace. Provide a workspace ID for a specific workspace or omit for My workspace.

Instructions

List semantic models in My workspace or in a specific workspace by id. Use list_workspaces first to resolve workspace ids. If workspace discovery is not authenticated and the user did not name a workspace, ask the user which workspace to use.

workspaceIdNoWorkspace/group id. Omit for My workspace.
Behavior2/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are present, so the description must disclose behavior fully. It only mentions listing models and workspace selection, but omits details about permissions, rate limits, or potential errors.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is short and front-loaded with the main purpose. It uses two sentences effectively without redundancy, but could be slightly more structured.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple list tool with one optional parameter and no output schema, the description covers the core functionality, usage prerequisites, and a fallback instruction. It is adequately complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with the workspaceId parameter described adequately in the schema. The description adds contextual advice but does not significantly enhance parameter understanding beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states it lists semantic models in My workspace or a specific workspace by id. It uses a specific verb and resource, but does not explicitly differentiate from sibling tools like list_semantic_models_in_workspace_via_modeling_mcp.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides guidance to use list_workspaces first to resolve workspace ids and instructions for handling authentication and user input. Lacks explicit exclusion of when not to use this tool.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
