# Business data with Combined Turn the user's business question into a bounded analysis over their existing Combined sources. Preserve their chosen apps, account, time window, and output. If they supplied files for a one-off analysis, use those files; this skill does not require moving them into Combined. ## Discover the data needed Use the connected Combined MCP server. Its six read-only tools are `list_sources`, `list_datasets`, `describe_dataset`, `get_freshness`, `search_context`, and `query_sql`. Read the actual tool schemas exposed by the client before calling them; client prefixes may differ. 1. Identify the requested account and sources with `list_sources`. Follow returned cursors when needed; the first page is not necessarily the entire source list. 2. Use `list_datasets` for relevant sources and `describe_dataset` for the required fields. Reuse current schema information already available in the conversation. Build logical relation names from returned metadata, not from provider labels or a tutorial's table names. 3. For time-sensitive questions, use `get_freshness` on the relevant source IDs. It accepts up to eight sources per call. `lastSuccessAt` records a successful commit; authorization completion or a running sync does not establish that records are current. If a needed source or field is absent, explain what part of the question can still be answered. Use the existing Set up or Access workflow when connection work is requested. The MCP analysis tools do
