The first MCP DB Hub release brings native, read-only database queries to AI agents, with an embedded English administration UI, per-Agent data-source grants, OAuth, and audit records.

Included

  • 18 database products, 20 tested version combinations: PostgreSQL, MySQL, MariaDB, TiDB, CockroachDB, TimescaleDB, SQLite, DuckDB, ClickHouse, MongoDB, Redis, Valkey, Elasticsearch, OpenSearch, Neo4j, Cassandra, ScyllaDB, and InfluxDB 1.x / 2.x / 3 Core.
  • 11 MCP tools: four discovery tools and seven native query families, over Streamable HTTP or a stdio bridge.
  • Enforced query boundaries: read-only engine settings and accounts where available, query validation, operation allowlists, timeouts, cancellation, bounded results, and lossless value encoding. InfluxDB 3 Core uses explicitly labeled query API isolation.
  • Administration: data-source configuration and connection evidence, Agent grants and token rotation/revocation, PKCE OAuth, encrypted database credentials, query previews, audit filtering, and local password recovery.

The support matrix records tested versions, capabilities and limits. Protocol compatibility alone does not establish verified support.

Packages require glibc 2.36 or newer and include the embedded UI, private C++ runtime libraries, bilingual documentation, examples, and third-party notices. Go and Node.js are unnecessary at runtime. Keep the entire extracted directory and launch it with ./mcpdbhub serve.

On macOS, use OrbStack or Docker to build from the tagged source. This release does not provide native macOS, Windows or Alpine/musl packages.

Verification

  • OrbStack Linux arm64: all 18 products / 20 version combinations passed, including 132 query/error cases and 89 rejected-operation cases.
  • GitHub CI: native Linux amd64 and arm64 UI builds, Go tests, race checks, numeric-parameter checks, and CLI builds passed.
  • Both actual dist archives were independently extracted and run in clean Debian containers: HTTP/stdio MCP discovery and PostgreSQL queries, persistent restart recovery, token revocation, and password recovery passed. Local amd64 archive execution used OrbStack emulation.
  • All four uploaded assets were downloaded again from GitHub and matched their local hashes. Both downloaded archives also passed the 16-check installation workflow.
  • The English management UI and published documentation were checked in local Chrome. Screenshots show the running product with isolated sample databases.

These checks cover the versions and scenarios recorded in the validation documentation; they do not establish compatibility with every database version, clustered deployment, or operating system. This release targets one instance and one administrator.
