Enable Claude to query your database directly using natural language
Example
Ask 'Show me top 10 customers by revenue this month' and get SQL results instantly
Eliminate manual SQL writing for ad-hoc queries, get insights 10x faster
Generate complex reports and analytics without leaving conversation
Example
Analyze sales trends, cohort retention, user behavior patterns conversationally
Democratize data access—non-technical team members can query databases
Understand database structure, relationships, and data models
Example
'Explain the user_orders table schema and its relationships'
Onboard engineers faster, explore unfamiliar databases efficiently
Share your MCP server with the developer community

MCP Clients MCP Server Databases
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:
PostgreSQL, MySQL, SQL Server, MariaDB, and SQLite.
DBHub implements MCP tools for database operations:
dbhub.toml configuration fileDBHub includes a built-in web interface 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.
See the full Installation Guide for detailed instructions.
Docker:
docker run --rm --init \
--name dbhub \
--publish 8080:8080 \
bytebase/dbhub \
--transport http \
--port 8080 \
--dsn "postgres://user:password@localhost:5432/dbname?sslmode=disable"
NPM:
npx @bytebase/dbhub@latest --transport http --port 8080 --dsn "postgres://user:password@localhost:5432/dbname?sslmode=disable"
Demo Mode:
npx @bytebase/dbhub@latest --transport http --port 8080 --demo
See Command-Line Options for all available parameters.
Connect to multiple databases simultaneously using TOML configuration files. Perfect for managing production, staging, and development databases from a single DBHub instance.
See Multi-Database Configuration for complete setup instructions.
# Install dependencies
pnpm install
# Run in development mode
pnpm dev
# Build and run for production
pnpm build && pnpm start --transport stdio --dsn "postgres://user:password@localhost:5432/dbname"
Run data quality queries to catch anomalies and inconsistencies
Example
Find duplicate records, missing values, orphaned foreign keys automatically
Maintain data integrity with less manual SQL work
Prerequisites
Time Estimate
15-30 minutes including configuration and testing
Steps
Troubleshooting

✗ Don't
💡 Pro Tips
Architecture
MCP server acts as bridge between Claude and database, translating natural language to SQL queries and returning results in structured format.
Protocols
Compatibility
✓ Use when
Use for ad-hoc data queries, exploratory analysis, report generation, schema exploration, and democratizing data access. Best for read-heavy analytics workloads.
✗ Avoid when
Avoid for production write operations, mission-critical transactions, real-time OLTP workloads, or when database contains sensitive PII without proper access controls. Use read replicas, not primary.
