Overview

databases
sql
postgresql
mysql
developer-tools

The dbhub MCP server connects MCP clients to PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite through one interface. It provides execute_sql and search_objects by default, with optional query-plan, health-check, and custom SQL tools. TOML configuration supports multiple connections, while read-only mode, row limits, query timeouts, SSH tunneling, and SSL/TLS address common operational needs. Reach for it when an agent needs database exploration, controlled diagnostics, query validation, or access to several database systems from one MCP process.

Use cases

Explore database schemas during local development
Validate queries and debug application data
Consolidate multiple database connections behind one MCP process
Run read-only production diagnostics
Expose curated database views to non-technical users

How Dbhub works

What the dbhub MCP server does

The dbhub MCP server gives MCP-compatible clients a common way to inspect and operate supported databases. It works with PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite, so a project can avoid running a separate MCP server for each database type. Multiple connections can be declared in a TOML configuration file.

The default interface is intentionally small: two tools are loaded and reported at about 1.4k tokens. That default set consists of execute_sql, for running SQL with transaction support and safety controls, and search_objects, for progressively exploring schemas, tables, columns, indexes, and procedures.

How it works

An MCP client sends tool requests to DBHub, which forwards database operations through the configured connection or connections. The server can run over stdio or HTTP. A built-in web workbench can also execute queries, run custom tools, and display request traces without an MCP client.

The dbhub MCP server includes controls for read-only operation, limiting returned rows, and setting query timeouts. SSH tunneling and SSL/TLS are available for database connections. These controls make it suitable for read-only troubleshooting or for exposing selected database access to users who should not receive unrestricted write access.

Setup and configuration

One installation path uses npx with an HTTP transport, a port, and a database connection string:

Terminal

npx @bytebase/dbhub@latest --transport http --port 8080 --dsn "postgres://user:password@localhost:5432/dbname?sslmode=disable"

Docker, an MCP Bundle with read-only installation, and a Claude Code plugin are also available. The command-line options and TOML configuration determine transport, connection details, and multi-database settings. Local development requires Node.js 22.5.0 or newer because the project uses Node's built-in SQLite module.

Tools and capabilities

execute_sql: Runs SQL and supports transactions and safety controls.
search_objects: Finds database objects and reveals schema details progressively.
explain_sql: An optional tool that returns an execution plan without executing the query.
health_check: An optional tool that reports connection-pool state and buffer-cache hit ratio.
Custom tools: Reusable parameterized SQL operations defined in dbhub.toml.

The default two-tool configuration keeps the MCP tool list small. Optional tools can be enabled when query planning, connection monitoring, or predefined database operations are needed.

Limitations and notes

The dbhub MCP server is positioned as a minimal database gateway rather than an enterprise governance layer. The supplied material specifically distinguishes it from Bytebase, which provides approval flows, access control, data masking, and audit logging beyond DBHub's stated guardrails. Review the configured permissions and database credentials before enabling write operations or exposing the service beyond a trusted environment.

Frequently Asked Questions about Dbhub

dbhub is an MCP server that connects AI clients to PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite. Its main tools are execute_sql for controlled SQL execution and search_objects for schema exploration, with optional tools for query plans, health checks, and custom parameterized operations.

Install it with npx, Docker, the read-only MCP Bundle, or the Claude Code plugin. The documented npx path runs `@bytebase/dbhub@latest` with a transport, port, and DSN; consult the installation and command-line configuration for other deployment options.

dbhub supports PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, and SQLite. TOML configuration can define multiple connections, allowing one DBHub process to provide access to several supported database systems.

Yes, dbhub is shown with Cursor as an MCP client. It can also be used with Claude Desktop, Claude Code, and VS Code, and supports stdio or HTTP transport according to the selected configuration.

Enable DBHub's read-only mode in its configuration or command-line setup. Read-only operation is listed as a guardrail for database access and is also used by the MCP Bundle installation.
