Connect Your AI Agent with Microsoft Power BI for Slack

Execute a DAX (Data Analysis Expressions) query against a Power BI dataset (semantic model). This is the primary analytics tool — use it to answer questions about values, aggregates, or filtered rows in a dataset. Use List Datasets first to resolve a dataset name → datasetId. The query must be a single valid DAX expression starting with EVALUATE. Table discovery (standard datasets): For datasets published from Power BI Desktop, the REST GET /datasets/{id}/tables endpoint is scoped to push datasets only and will not list tables. Use EVALUATE INFO.TABLES() instead — it returns every table name in the semantic model. Typical agent flow: List Workspaces → List Datasets → Execute DAX Query (EVALUATE INFO.TABLES()) → Execute DAX Query (EVALUATE 'TableName'). Common patterns: • Discover all tables — EVALUATE INFO.TABLES() (use this before querying an unknown dataset) • List all rows of a table — EVALUATE 'Species' • Filter — EVALUATE FILTER('Species', 'Species'[dietType] = "Carnivore") • Top N by column — EVALUATE TOPN(5, 'Species', 'Species'[weightKg], DESC) • Aggregate single value — EVALUATE ROW("Total", SUMX('Species', 'Species'[weightKg])) • Peek at a table's columns — EVALUATE TOPN(0, 'Species') (returns an empty rowset with column names in the response). Limits: max 100,000 rows or 1,000,000 values per query, and DEFINE/multiple-statement queries are not supported via REST. The tenant must have 'Dataset Execute Queries REST API' enabled (admin setting) or the call returns 401/403. Pass workspaceId (from List Workspaces) or workspaceName to target a specific workspace, or omit both for My workspace. See the documentation

Trigger a refresh of a Power BI dataset. Returns 202 Accepted on success; the request ID is available in the Location response header (last path segment) and x-ms-request-id header — use Get Refresh History to check status. Use List Datasets first to resolve a dataset name → datasetId. Pass workspaceId (from List Workspaces) or workspaceName to target a specific workspace, or omit both for My workspace. notifyOption controls email notifications on refresh outcome: NoNotification (default), MailOnCompletion, or MailOnFailure. Power BI Pro licenses allow up to 8 scheduled refreshes per day; Premium allows 48. Note: Push datasets accept this endpoint but the refresh is metadata-only (tile refresh), not a data refresh — no cancellable history entry is produced. See the documentation

List the Power BI workspaces (groups) the authenticated user can access. Use this tool first whenever the user refers to a workspace by name — it returns the id you need to pass as workspaceId to other tools. Power BI has no /me endpoint, so the set of accessible workspaces is the user's primary context (the 'who am I' signal for this app). Every item in the response includes id, name, isReadOnly, isOnDedicatedCapacity, and type. Note: when a user says 'my workspace' without a name, they may mean personal My workspace (implicit — pass no workspaceId to other tools) OR a specific named workspace — ask only if ambiguous. See the documentation

List Power BI reports in a workspace. Defaults to the authenticated user's personal My workspace when no workspace is specified. Pass workspaceId (preferred, from List Workspaces) OR workspaceName to scope to a specific workspace — the tool resolves the name to an ID server-side. Each report includes id, name, webUrl, embedUrl, datasetId, and reportType (PowerBIReport or PaginatedReport). Note: reports cannot be created via the REST API — they are published from Power BI Desktop. See the documentation

List Power BI datasets (semantic models) in a workspace. Defaults to the authenticated user's personal My workspace when no workspace is specified. Pass workspaceId (preferred, from List Workspaces) OR workspaceName to scope to a specific workspace. Each dataset includes id, name, webUrl, addRowsAPIEnabled (true for Push Datasets), isRefreshable, and defaultMode (Push, Streaming, PushStreaming, AsOnPrem, AsAzure). Use this tool to resolve a dataset name → ID before calling Refresh Dataset, Execute DAX Query, Get Refresh History, or Add Rows To Push Dataset. For push-dataset row inserts, call the dataset's GET tables endpoint (not exposed as a separate tool) by inspecting the dataset's name → tables are defined at dataset creation; the table name is the string configured at creation time (e.g., Species). See the documentation

List Power BI dashboards in a workspace. Defaults to the authenticated user's personal My workspace when no workspace is specified. Pass workspaceId (preferred, from List Workspaces) OR workspaceName to scope to a specific workspace. Each dashboard includes id, displayName, isReadOnly, webUrl, and embedUrl. Note: dashboards cannot be created via the REST API — they are built interactively in the Power BI service. See the documentation

Get reports from a Power BI workspace. See the documentation

Retrieve metadata for a single Power BI report by ID. Uses My workspace by default; set Workspace (Group) ID for a specific workspace. See the documentation

Get the refresh history for a Power BI dataset. Use List Datasets first to resolve a dataset name → datasetId. Pass workspaceId (from List Workspaces) or workspaceName to scope to a specific workspace, or omit both for My workspace. Each entry includes requestId, refreshType (OnDemand, Scheduled, ViaApi, etc.), startTime, endTime, status (Completed, Failed, Disabled, Cancelled, Unknown — Unknown means still in progress), and serviceExceptionJson on failures. See the documentation

Export a Power BI report to a file format such as PDF, PPTX, or PNG. Requires a report ID (use List Reports to find it) and defaults to PDF if no format is given. Pass workspaceId (from List Workspaces) or workspaceName to target a specific workspace, or omit both for My workspace. Supported format values depend on the report type: Power BI reports support PDF, PPTX, PNG. Paginated reports additionally support CSV, XLSX, DOCX, XML, MHTML. This API is Premium-only: requires the workspace to be backed by Premium capacity, Premium Per User, or Embedded capacity. On shared (free) capacity it returns FixedCapacityLimitExceeded / 403. The export is asynchronous — this tool starts the export, then polls until the job reaches Succeeded or Failed (or pollTimeoutSeconds elapses), then downloads the file and returns it as base64 along with the job metadata. PNG exports only work for single-page reports. For PPTX/PDF, pass pages (array of page names, e.g., ["ReportSection", "ReportSection1"]) to limit the export. See the documentation

Append rows to a table in a Power BI Push Dataset (streaming / realtime data). Only works for datasets created via the REST API with defaultMode: Push — these datasets expose addRowsAPIEnabled: true on the object returned by List Datasets. Use List Datasets first to resolve a dataset name → datasetId and inspect its tables for the exact tableName (case-sensitive). Pass workspaceId (from List Workspaces) or workspaceName to target a specific workspace, or omit both for My workspace. Rows must match the table's column schema. rows accepts either a JSON array ([{...}, {...}]) or a JSON-stringified array. Each row is an object of columnName → value. Common mistakes: (1) case mismatch on tableName returns 404 — copy the exact string from the dataset's tables array. (2) Sending values that don't match the declared column data type returns RequestedResourceNotFound or DMTS_DatasourceHasNoCredentialsError. Push-dataset rows have no individual IDs and cannot be updated or deleted — only appended or bulk-cleared. See the documentation
