A development guide for OxMySQL, a FiveM library that connects server code to MySQL or MariaDB databases. It covers reading, inserting, changing, and deleting stored data, as well as transactions.

Use it when adding player, inventory, economy, or other persistent data to a FiveM resource through SQL queries.

It helps server code store and retrieve game data without writing database integration from scratch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00055	$0.00839
Opus 5.5	$0.00022	$0.00336
Sonnet 5.5	$0.00011	$0.00168
Haiku 4.5	$0.00006	$0.00084

Security

Grade A, and why

oxmysql scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

oxmysql

Server-side MySQL/MariaDB access for FiveM through the MySQL table (replacement for mysql-async and ghmattimysql).

Activation Contract

Load this skill when the user writes or edits database code in a FiveM resource: SELECT/INSERT/UPDATE/DELETE, upserts, transactions, MySQL.*, exports.oxmysql, or migrating from mysql-async.

Hard Rules

Server only. Add server_script '@oxmysql/lib/MySQL.lua' to fxmanifest.lua above other server scripts.
MySQL.Sync.* and MySQL.Async.* (mysql-async compatibility layer) are NOT available. Replace them with MySQL.query, MySQL.scalar, MySQL.single, MySQL.insert, MySQL.update, MySQL.prepare, MySQL.transaction, each with a .await variant.
@named placeholders are deprecated: use positional ? with an array of values. prepare accepts only ? (and ?? for column names).
Never concatenate user input into SQL; every value goes through a placeholder.
Every function takes (query, params, callback); use .await to yield instead of nesting callbacks.
Use transaction when several writes must succeed or fail together; it rolls back on any failure.
Use rawExecute only when the normalized result shape of query/prepare is insufficient.
Prefer MariaDB over MySQL 8 for compatibility.

Decision Gates

Need	Call	Returns
Many rows	`MySQL.query.await(sql, params)`	array of rows
One row	`MySQL.single.await(sql, params)`	row or nil
One value (COUNT, one column)	`MySQL.scalar.await(sql, params)`	value or nil
Insert	`MySQL.insert.await(sql, params)`	insert id
Update / delete count	`MySQL.update.await(sql, params)`	affected rows
Hot path, repeated statement	`MySQL.prepare.await(sql, params)`	rows / value
Several statements atomically	`MySQL.transaction.await({ { query, values }, ... })`	success boolean
Raw, unnormalized result	`MySQL.rawExecute.await(sql, params)`	raw result

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

oxmysql is a skill published in the GitHub repository germanfndez/fiveai-skills (20 stars, last pushed 20d ago), licensed MIT. It adds 55 tokens to every session and 839 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
