SQL MCP Server

The governed SQL gateway for untrusted AI agents.

面向不可信 AI Agent 的受控 SQL 数据访问网关。通过显式 Entity、关系代数 IR 和 参数化 codegen 访问 PostgreSQL、MySQL 与 OceanBase,不接受任意 SQL,不提供 DDL

核心差异

  • 确定性执行:Agent 只能组合受控工具和白名单 IR;
  • 字段与行治理:RBAC、字段 ACL、row policy 和 mask 统一强制;
  • 成本可控:EXPLAIN 预筛、结果上限、超时和 session/tenant 预算;
  • 默认拒绝:安全能力无法证明时 fail closed;
  • 可审计:配置热重载、异步审计和 OpenTelemetry hook。

运行时安全行为以安全模型为准;Provider 验证边界与证据层级 以兼容矩阵为准;威胁、控制与剩余风险见 威胁模型。所有对外声明的证据汇总见 架构、安全边界与证据索引不以本页摘要为准。
