Simple Snowflake MCP Tools (15)
execute-snowflake-sql
Executes a SQL query on Snowflake and returns the result. Supports `json` (default), `markdown`, and `csv` output via the `format` argument.
execute-query
Executes a SQL query with server-enforced read-only protection. In read-only mode (the default) only `SELECT`, `SHOW`, `DESCRIBE`, `EXPLAIN`, and `WITH` statements (without DML) are allowed. Read-only mode is governed **solely by server configuration** and cannot be relaxed by the caller. Supports…
get-connection-info
Returns current Snowflake connection information and server status.
list-snowflake-warehouses
Lists available Data Warehouses (DWH) on Snowflake. Pass `include_details: false` for names only.
list-databases
Lists all accessible Snowflake databases. Supports a `pattern` filter (wildcards) and `include_details`.
list-schemas
Lists schemas in a `database`. Supports a `pattern` filter (wildcards) and `include_details`.
list-tables
Lists tables in a `database`/`schema`. Supports a `pattern` filter (wildcards) and `include_details`.
list-views
Lists views in a `database`/`schema`. Supports a `pattern` filter (wildcards) and `include_details`.
