Documentation

From the project's GitHub README.

database-mcp

MCP servers that give AI clients safe, structured access to SQL databases.

One installable package per database engine. Every package exposes the same minimal two-tool surface, execute_sql and search_objects, with guardrails on by default: read-only mode, row caps, and statement timeouts.

Packages

Engine	TypeScript (npm)	Version
SQLite	`@database-mcp/sqlite`
libSQL	`@database-mcp/libsql`
MySQL	`@database-mcp/mysql`
MariaDB	`@database-mcp/mariadb`
Postgres	`@database-mcp/postgres`

All five are published, provenance-attested, and pass the shared conformance suite against real databases in CI.

Python, Go, and Rust implementations are planned once the TypeScript line is complete. All packages, in every language, pass the same language-agnostic conformance suite, so behavior is identical everywhere.

Design principles

Two tools, no more. A tiny tool surface keeps the model's context window clean. search_objects progressively discloses schema: call it with no arguments to list tables, with a table name to get columns, indexes, and foreign keys.
Safe by default. Read-only mode is enforced in two layers: a conservative SQL guard, plus a session-level read-only setting in the database itself. Rows are capped (default 1000) and statements time out (default 30s).
Configured at launch, never via chat. Connection details come from flags, a YAML config file, or environment variables. Credentials are never accepted through a tool call.
Secrets never appear in logs. Passwords live in non-printable secret types, DSNs are sanitized before logging, and a redaction filter guards the log boundary.

Quick start

Pick your engine's package; each README has the full config surface. SQLite:

{
  "mcpServers": {
    "sqlite": {
      "command": "npx",
      "args": ["-y", "@database-mcp/sqlite", "--dsn", "/absolute/path/to/database.db"]
    }
  }
}

Networked engines take credentials from the environment (MYSQL_*, MARIADB_*, POSTGRES_*/DATABASE_URL, LIBSQL_URL/LIBSQL_AUTH_TOKEN), *_FILE mounted secrets, or a YAML file via --config. Never from a chat prompt.

Contributing

See CONTRIBUTING.md. The short version: the conformance suite is the definition of done. A change is mergeable only when conformance/run.mjs passes against every affected server.
