Microsoft SQL Server Tools (5)

list_profiles

List configured connection profiles. Call first when picking a non-default profile. Returns `name`, `description` and `allow_write` per profile.

Inline limit: 500 rows (hard ceiling 1000). Snapshot limit: 10 000 rows (hard ceiling 50 000). Prefer `analyze_query` for plan tunin…

analyze_query

Analyze execution plan for a read-only SELECT. Returns compact JSON summary (cost, operators, cardinality, warnings, `missing_indexes`, waits, stats); no result rows, full XML at `plan_uri`.

run_command
