Database MCP Server

A governed database MCP server for AI agents

What a raw MCP server leaves wide open

Every agent shares one connection string

A raw MCP server hands each agent the same database credentials. With no per-agent identity, you can't tell which agent ran which query — or revoke just one of them.

Full-table reads, PII included

Without masking on the read path, an agent that queries a users table sees every email, token, and secret in clear text — the model, the logs, and the context window now hold it too.

Writes reach production unreviewed

An agent can run an UPDATE or a DROP with no approval, no SQL review, and no rollback path. One bad tool call and there's no record of what changed or who to ask.

How Bytebase governs the agent-to-database path

Per-agent identity, not a shared secret

Every agent connects through Bytebase as itself — scoped, revocable, and traceable — and never holds a database credential.

Masking on the read path

Sensitive columns are masked at query time, so an agent gets the answer it needs without ever seeing the raw PII behind it.

Writes go through review

Every agent write clears the same SQL review and approval bar as a human change — with full history and a clean rollback path.

One MCP server, controls for every team

Drop-in MCP endpoint

Point any MCP client at Bytebase; agents get governed database access with no bespoke proxy or credential broker to build.

Works across engines

One MCP server for PostgreSQL, MySQL, SQL Server, Oracle, and 20+ engines — the same governance everywhere.

Self-hosted, single image

Run it in your own infrastructure as one Docker image; data and credentials never leave your network.

Designed to integrate across modern enterprise environments

Bytebase connects to databases, developer tooling, and collaboration platforms to fit naturally into complex, multi-tool enterprise ecosystems.
