Limits

Generated from the exported limits object of @sezzlee/mssql-mcp 0.2.1.

Every limit is fixed at build time; none is configurable. A call that would cross one either answers with truncated: true and a way to continue, or fails with resource_limit.

Queries

Limit	Value
Rows `run_query` returns when `maxRows` is omitted	100
Largest `maxRows` for `run_query`	1,000
Most columns `describe_table` reports for one table	512
Largest serialized answer; a longer result is cut at the last row that fits	512 KB
Longest text value returned for one cell, in characters; a longer one is cut	4,096
Longest binary value returned for one cell, before base64 encoding; a longer one is cut	4 KB
Deadline for a statement when the call sets no `timeoutMs`; `SEZZLEE_MSSQL_QUERY_TIMEOUT_MS` replaces it	30 s

Catalogue search

Limit	Value
Objects `search_catalog` returns when `maxResults` is omitted	50
Largest `maxResults` for `search_catalog`	200
Tables and views the search index holds; past it the catalogue is reported incomplete	5,000
Columns the search index holds; past it the catalogue is reported incomplete	50,000
Longest description kept for one object or column	160
How long the search index is reused before the next search reads the catalogue again	900 s
Words of one `query` that are searched; the rest are ignored	16
Index terms one query word may expand to by prefix	32
Entries in one result's `matched` list	8
Constraints `describe_table` lists for one table	256

Connections

Limit	Value
Connections open to SQL Server at once	4
Calls that may wait for a free connection before a new one fails with `resource_limit`	32
Time to open a connection; `SEZZLEE_MSSQL_CONNECT_TIMEOUT_MS` replaces it	15 s
Time a cancelled statement may take to stop before its connection is discarded instead of reused	5 s
