Direct MySQL database access with mysql2 driver -- connection pools, prepared statements, transactions, streaming, typed queries, error handling.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MySQL Patterns (mysql2) > **Quick Guide:** Use **mysql2/promise** for all new code -- it provides async/await support over the mysql2 callback API. Always use `createPool()` (never `createConnection()` in production) with `execute()` for parameterized queries (prepared statements, LRU-cached). Type query results with `RowDataPacket` generics for SELECTs and `ResultSetHeader` for INSERT/UPDATE/DELETE. For transactions, acquire a dedicated connection with `pool.getConnection()`, wrap in try/finally to guarantee `connection.release()`. Never interpolate user input into SQL strings -- always use `?` placeholders. Handle `ER_DUP_ENTRY` and `ER_LOCK_DEADLOCK` explicitly in catch blocks. --- <critical_requirements> ## CRITICAL: Before Using This Skill **(You MUST use `execute()` with `?` placeholders for ALL queries containing user input -- NEVER interpolate values into SQL strings with template literals or string concatenation)** **(You MUST use `pool.getConnection()` for transactions and release the connection in a `finally` block -- pool convenience methods (`pool.execute()`) use a different connection per call and cannot maintain transaction state)** …

How to install
mdr add agents-inc/skills/api-database-mysql@sha256:0c1320176437e116The line at the top of this page pins the label git:20261016.afd0e14, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
