Support for Embedded Data Sources

[shai-li-valdarsky]

Current Limitation

The Tableau MCP server currently only supports querying published data sources. Embedded (non-published) data sources cannot be queried directly through the MCP tools (query-datasource, get-datasource-metadata, etc.). This means stakeholders need to use workarounds to access the datasources which is extremely time consuming for everyone - or they have to compromise and download the data from the view.

Proposed Feature

Extend the MCP server to support embedded data sources by:

1. Discovery: Add ability to list embedded data sources within a workbook

   • New tool or extend get-workbook to include embedded data source metadata

2. Metadata Access: Extend get-datasource-metadata to work with embedded sources

   • Reference format: workbook_id:datasource_name or similar

3. Querying: Extend query-datasource to support embedded sources

   • Allow queries against embedded sources using workbook/source identifiers

Thanks!

Hey @shai-li-valdarsky, thanks for the issue. VizQL Data Service is working on adding support for embedded data sources as we speak, but I don't have a definitive timeline I can share yet. Stay tuned.
