"Connecting to PostgreSQL database, retrieving table schema, and executing SQL queries" matching MCP servers:
- AlicenseAqualityBmaintenanceAn MCP server that lets Claude query a mock business SQL database in plain language through read-only tools, with server-side guardrails that enforce SELECT-only queries and block access to sensitive payment data.3MIT
- AlicenseBqualityBmaintenanceEnables secure database operations on SQL Server instances through a three-tier safety system, supporting schema exploration, query execution, performance analysis, and data export with configurable security levels from read-only to full development access.16255MIT
- Alicense-qualityAmaintenanceA governed SQL gateway for untrusted AI agents, providing controlled access to PostgreSQL, MySQL, and OceanBase with RBAC, field ACLs, row policies, and cost controls.MIT
- Alicense-qualityAmaintenanceEnables LLMs to propose UPDATE/DELETE SQL that is run in a transaction, measured, and rolled back, requiring human approval before applying to prevent unauthorized changes.962MIT
- Alicense-qualityCmaintenanceValidates SQL queries via AST parsing, ensuring they are single read-only SELECTs on allowed tables with enforced LIMITs, and masks PII columns based on user roles. Provides a tamper-evident audit log and runs fully offline.MIT
- Alicense-quality-maintenanceC# SQL Agent MCP server featuring raw SQL input, strict AST validation, and an embedded Admin UI. Eliminates LLM hallucinations and security risks across 6 major databases.9Apache 2.0
