At a Glance & Executive Verdict
Powerbi Analyst MCP
Data Visualization · Local stdio
Quality: 55/100 (Good) | Auth: OAuth 2.0
Microcharts
Data Visualization · Local stdio
Quality: 68/100 (Great) | Auth: No auth required
Verdict Summary: Choose Powerbi Analyst MCP if you need specialized Data Visualization tools running via a local process. Choose Microcharts if your workspace requires Data Visualization integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Powerbi Analyst MCP when:
You need dedicated capabilities in the Data Visualization domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: OAuth 2.0 (Free / Open Source).
You have access to required keys: POWERBI_ANALYST_MCP_CLIENT_ID, POWERBI_ANALYST_MCP_TENANT_ID.
Connect LLMs to Power BI semantic models. Browse workspaces, tables, and measures, run DAX queries, and automatically page large results via local CSV.
Word-sized charts (sparklines, bars, bullets — 106 types) rendered to self-contained SVG with generated alt text. Three tools: find the right chart for a question, get its wiring, render it. Works in chat surfaces that can't run React. Install via npx -y @microcharts/mcp.
Category & Scope
Tools & Capabilities Breakdown
Powerbi Analyst MCP Tools (12)
authenticate
Sign in via OAuth device code — returns a URL + one-time code; call again to complete
logout
Clear the cached token (forces re-authentication)
list_apps
List all Power BI apps you have access to — **start here**; returns `workspaceId` for each app
list_datasets
List datasets / semantic models in a workspace (use `workspaceId` from `list_apps`)
get_dataset_info
Metadata and last 5 refresh history entries for a dataset
list_tables
All visible tables in a dataset
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Powerbi Analyst MCP is categorized under Data Visualization and uses a local stdio subprocess. In contrast, Microcharts belongs to Data Visualization using local stdio subprocess. Select Powerbi Analyst MCP when you need capabilities focused on data visualization and Microcharts when you require tools for data visualization.
Measures with name, table, description, and format string
list_columns
Columns with data type and key flag
execute_dax
Run a DAX query — inline for small results, local CSV for large ones. Pass `query_summary` to log the query for future reference.
read_query_result
Page through a large CSV result without loading it all into context
search_query_history
Search the local query log by keyword, dataset, or time range — find prior DAX and results across sessions
delete_query_log_entry
Remove a query log entry (e.g. when the approach turned out to be wrong)
Microcharts Tools (3)
find_microchart
Rank microcharts chart types against a plain-language question about data ("is it trending?", "error budget", "part to whole"). Returns candidates with the reason each matched. Start here when you know the question, not the chart.
get_microchart
Full wiring detail for one chart by slug: import paths, its props plus the shared props, data shape, best/avoid guidance, a copy-runnable example, and `sample` — the example as JSON props you can pass straight to render_microchart.
render_microchart
Render a chart to a finished, self-contained SVG (styles embedded) plus its generated alt text — for surfaces that can't run React. Pass the series as `data`; put other props (value, target, curve, color, width) in `props`. Each chart takes its own data shape — get_microchart returns a valid `sample` to adapt.
