sql-mcp-server
A governed SQL gateway for untrusted AI agents, providing controlled access to PostgreSQL, MySQL, and OceanBase with RBAC, field ACLs, row policies, and cost controls.
README
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。
