Using MCP for Large Sales Data Queries

(0) ShareShare
ReportReport
Posted on by 21

I’m using MCP to analyze sales data (e.g., total sales for 2025, Q1 sales, and comparisons with current data).

To handle large datasets, I added instructions in the Overview section to:

  • Fetch records in batches (e.g., 1500 at a time)
  • Continue automatically for all batches
  • Aggregate totals across batches
 (this is from MCP Overview page)

Problem:

  • First batch works correctly
  • Copilot asks to continue instead of proceeding automatically
  • Next batch often fails with “too much data”
  • Results are incomplete and inconsistant
Question:
  • What is the recommended approach for large datasets?
  • Does MCP support pagination/aggregation via Overview instructions?
  • How can we ensure automatic batch processing without prompts?
  • Should this be handled outside MCP (e.g., APIs or pre-aggregated data), and if so, can we process/aggregate the data externally and then load or expose the summarized data back into MCP for querying? If yes, how to do it?
I have the same question (0)
