Database
Give your agent safe, structured access to MySQL, MariaDB, PostgreSQL, and SQLite through Haymon’s database MCP—locally via Docker stdio or HTTP.
Overview
Haymon Database MCP is an MCP server for the build phase that connects agents to MySQL, MariaDB, PostgreSQL, and SQLite via Docker stdio or local HTTP.
What is this MCP server?
- Single MCP server for MySQL, MariaDB, PostgreSQL, and SQLite
- OCI image ghcr.io/haymon-ai/database:0.7.0 with stdio and HTTP transport modes
- HTTP mode bind defaults: host 127.0.0.1, port 9001, configurable allowed origins
- Docker runtime hint for reproducible local or team environments
- Catalog version 0.7.0 aligned with container tag
- Supports 4 SQL engines: MySQL, MariaDB, PostgreSQL, SQLite
- Image: ghcr.io/haymon-ai/database:0.7.0
- HTTP default bind: 127.0.0.1:9001

What problem does it solve?
Solo builders repeatedly paste SQL and connection details into agent chats instead of a governed MCP path to the databases their app already uses.
Who is it for?
Full-stack indies who already use Docker and want multi-engine SQL access from Claude Code or Cursor without a proprietary hosted DB MCP.
Skip if: Builders who need managed cloud-only DB MCP with zero local ops or who only need document/NoSQL stores.
What do I get? / Deliverables
Running the Haymon container gives your agent MCP tools against four SQL engines so schema checks and queries stay consistent across sessions.
- Running Haymon database MCP container
- Agent tools spanning MySQL, MariaDB, PostgreSQL, SQLite
- Configurable local HTTP MCP endpoint on port 9001 by default
Recommended MCP Servers
Journey fit
Database inspection and mutation support land in build backend when solo builders wire persistence, debug schema, and validate queries alongside app code. Backend subphase fits MCP servers that expose SQL engines and connection tooling rather than marketing or deploy automation.
How it compares
Self-hosted multi-engine database MCP, not a hosted analytics warehouse integration or ORM codegen skill.
Common Questions / FAQ
Who is ai.haymon/database for?
Developers shipping SaaS or APIs who want MCP agents to work against MySQL, MariaDB, PostgreSQL, or SQLite through Haymon’s Docker-published server.
When should I use ai.haymon/database?
Use it during build and backend debugging when you need repeatable agent access to relational schema and queries on your own machines or CI-adjacent environments.
How do I add ai.haymon/database to my agent?
Pull ghcr.io/haymon-ai/database:0.7.0, start stdio mode for IDE MCP or HTTP mode with --host and --port, then point your client at the process or http://127.0.0.1:9001/mcp with database connection env vars per Haymon docs.
