Endpoint (Streamable HTTP)

On the wire — recorded from a real request

Symptom

what you'll observe

One tool call returns megabytes of text and blows the context window / times out.

Cause

what this reproduces

Returning an unpaginated dump (full file, whole table) instead of a summary or page.

Fix

how you'd resolve it

Paginate, truncate, and summarise large results; return handles/links for bulk data.

Try it with curl

bash
