MCP Snowflake Service

A Model Context Protocol (MCP) server that provides Claude access to Snowflake databases. / 一个为 Claude 提供 Snowflake 数据库访问能力的 MCP (模型上下文协议) 服务器。

This server implements the Model Context Protocol to allow Claude to:

• Execute SQL queries on Snowflake databases
• Automatically handle database connection lifecycle (connect, reconnect on timeout, close)
• Handle query results and errors
• Perform database operations safely

此服务器实现了模型上下文协议，使 Claude 能够：

• 在 Snowflake 数据库上执行 SQL 查询
• 自动管理数据库连接生命周期（连接创建、超时重连、连接关闭）
• 处理查询结果和错误
• 安全地执行数据库操作

notes / 备注

mcp‑server‑snowflake controls database access rights precisely by way of database users. If you only need to read data, just assign a user with read‑only database permissions./ mcp-server-snowflake 控制数据库访问权限，是通过数据库用户来精准实现的。如果你只想读取数据，给个只有读取数据库权限的用户就行了。
