| 30 | MCP Clients MCP Server Databases |
| 31 | ``` |
| 32 | |
| 33 | DBHub is a zero-dependency, token efficient MCP server implementing the Model Context Protocol (MCP) server interface. This lightweight gateway allows MCP-compatible clients to connect to and explore different databases: |
| 34 | |
| 35 | - **Local Development First**: Zero dependency, token efficient with just two MCP tools to maximize context window |
| 36 | - **Multi-Database**: PostgreSQL, MySQL, MariaDB, SQL Server, and SQLite through a single interface |
| 37 | - **Multi-Connection**: Connect to multiple databases simultaneously with TOML configuration |
| 38 | - **Guardrails**: Read-only mode, row limiting, and query timeout to prevent runaway operations |
| 39 | - **Secure Access**: SSH tunneling and SSL/TLS encryption |
| 40 | |
| 41 | ## Supported Databases |
| 42 | |
| 43 | PostgreSQL, MySQL, SQL Server, MariaDB, and SQLite. |
| 44 | |
| 45 | ## MCP Tools |
| 46 | |
| 47 | DBHub implements MCP tools for database operations: |
| 48 | |
| 49 | - **[execute_sql](https://dbhub.ai/tools/execute-sql)**: Execute SQL queries with transaction support and safety controls |
| 50 | - **[search_objects](https://dbhub.ai/tools/search-objects)**: Search and explore database schemas, tables, columns, indexes, and procedures with progressive disclosure |
| 51 | - **[Custom Tools](https://dbhub.ai/tools/custom-tools)**: Define reusable, parameterized SQL operations in your `dbhub.toml` configuration file |
| 52 | |
| 53 | ## Workbench |
| 54 | |
| 55 | DBHub includes a [built-in web interface](https://dbhub.ai/workbench/overview) for interacting with your database tools. It provides a visual way to execute queries, run custom tools, and view request traces without requiring an MCP client. |
