Polyglot Database MCP
Connect one MCP server to many database engines so your agent can query SurrealDB, ArangoDB, Cassandra, CouchDB, Virtuoso, and peers without one-off adapters.
Overview
Polyglot Database MCP is an MCP server for the Build phase that unifies agent access across twenty database engines through one stdio OCI server.
What is this MCP server?
- Unified MCP surface for 20 databases including SurrealDB, ArangoDB, Virtuoso, CouchDB, and Cassandra
- Ships as OCI image ghcr.io/hyperpolymath/poly-db-mcp:main with stdio transport
- Hyperpolymath Polyglot Database MCP v1.0.0 from github.com/hyperpolymath/poly-db-mcp
- Reduces N separate MCP servers when prototyping multi-engine or migration-heavy backends
- Fits agent-driven schema exploration, query drafting, and ops runbooks during backend build
- 20 supported databases named in catalog description (SurrealDB, ArangoDB, Virtuoso, CouchDB, Cassandra, and more)
- OCI identifier ghcr.io/hyperpolymath/poly-db-mcp:main
- Server version 1.0.0 Polyglot Database MCP
What problem does it solve?
Indie builders juggling experimental databases burn setup time installing a different MCP or CLI adapter for every new engine the agent should touch.
Who is it for?
Solo developers comparing or operating multiple database backends who want a single MCP registration during backend and integration work.
Skip if: Production teams that standardize on one managed Postgres with a dedicated, audited connector and no polyglot experimentation.
What do I get? / Deliverables
After registering poly-db-mcp, your agent can target up to twenty supported databases from one integration path while you flesh out backend and data-layer code.
- Single MCP entry point covering 20 named database ecosystems
- Agent-assisted queries and schema operations across enabled engines
- Faster backend integration experiments without per-DB MCP boilerplate
Recommended MCP Servers
Journey fit
Build is where data stores get wired into products; a polyglot DB MCP collapses integration work across engines you are already evaluating. Integrations subphase matches exposing multiple database backends to the agent through a single stdio OCI container workflow.
How it compares
Multi-engine database MCP bridge, not a hosted DBaaS console or a single-engine ORM skill.
Common Questions / FAQ
Who is Polyglot Database MCP for?
It is for builders and agent users who work with more than one database technology and want one MCP server instead of many per-engine plugins.
When should I use Polyglot Database MCP?
Use it during build and integrations while you prototype APIs, migrate data, or let an agent inspect schemas across SurrealDB, ArangoDB, Cassandra, and similar stores.
How do I add Polyglot Database MCP to my agent?
Run the OCI image ghcr.io/hyperpolymath/poly-db-mcp:main with stdio transport, configure connection settings per database in your environment, and register the server in your MCP client.
