About
MCP server for SQLite databases. Read-only by default, row caps, statement timeouts.
Security Report
database-mcp is a well-designed, security-conscious MCP server suite for SQL databases. The codebase demonstrates strong security practices: read-only mode is enforced at multiple layers, credentials are properly handled via environment variables and secrets abstraction, and input validation uses parameterized queries throughout. Minor code quality observations exist around error handling breadth and session pooling, but these do not constitute security vulnerabilities. Permissions are appropriate and proportionate to the server's purpose of providing safe, structured database access. Package verification found 2 issues (1 critical, 0 high severity).

database-mcp
MCP servers that give AI clients safe, structured access to SQL databases.
One installable package per database engine, in TypeScript (npm) and Python
(PyPI). 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) | Python (PyPI) |
|---|---|---|
| SQLite | @database-mcp/sqlite  | database-mcp-sqlite  |
| libSQL | @database-mcp/libsql  | database-mcp-libsql  |
| MySQL | @database-mcp/mysql  | database-mcp-mysql  |
| MariaDB | @database-mcp/mariadb  | database-mcp-mariadb  |
| Postgres | @database-mcp/postgres  | database-mcp-postgres  |
Both lines are published and pass the same language-agnostic conformance suite against real databases in CI, so behavior is identical regardless of language. Every engine is also listed on the MCP Registry with both install options.
Go and Rust implementations are planned.
Design principles
- Two tools, no more. A tiny tool surface keeps the model's context window
clean.
search_objectsprogressively 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 via npm:
{
"mcpServers": {
"sqlite": {
"command": "npx",
"args": ["-y", "@database-mcp/sqlite", "--dsn", "/absolute/path/to/database.db"]
}
}
}
Or via PyPI: use "command": "uvx" and
"args": ["database-mcp-sqlite", "--dsn", "/absolute/path/to/database.db"].
Flags, environment variables, and YAML config are identical across both
lines.
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.

suite is the definition of done. A change is mergeable only when
