Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00089 | $0.01722 |
| Opus 5 | $0.00044 | $0.00861 |
| Sonnet 5 | $0.00018 | $0.00344 |
| Haiku 4.5 | $0.00009 | $0.00172 |
Grade B, and why
mysqlsh scanned grade B with 1 finding 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 11d 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Restrict file permissions: `chmod 600 ~/.mylogin.cnf`. How it starts
The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MySQL Shell (mysqlsh) Production Standards
MySQL Shell is an advanced client and automation tool with JavaScript, Python, and SQL modes. It is the only supported interface for InnoDB Cluster management via the AdminAPI.
2.1 Execution Modes
| Mode | Activate | Use Case |
|---|---|---|
SQL (\sql) |
--sql |
Ad-hoc querying |
JavaScript (\js) |
--js |
AdminAPI, automation, util.* functions |
Python (\py) |
--py |
AdminAPI, automation, util.* functions |
- [ALWAYS] use
\jsor\pymodes for administrative and automation tasks. - [ALWAYS] use
\sqlmode strictly for ad-hoc querying.
2.2 AdminAPI & InnoDB Cluster Management
The dba global object (AdminAPI) is the only recommended way to deploy and manage InnoDB Cluster, ClusterSet, and ReplicaSet topologies.
Setup Rules:
- [ALWAYS] run
dba.configureInstance('user@host:3306')before adding a node. It validates prerequisites (Performance Schema, InnoDB engine,server_id). - [ALWAYS] create a dedicated cluster admin account via the
clusterAdminoption. - [ALWAYS] require an odd number of nodes (minimum 3) for quorum, distributed across different physical fault domains.
- [ALWAYS] use stable hostnames defined in DNS or
/etc/hosts. - [NEVER] use
dba.deploySandboxInstance()for production. It is for local testing only.
Example:
dba.configureInstance('admin@node1:3306')
var cluster = dba.createCluster('myCluster')
cluster.addInstance('admin@node2:3306')
cluster.addInstance('admin@node3:3306')
cluster.status()
Key AdminAPI Operations:
| Method | Purpose |
|---|---|
dba.createCluster() |
Create new InnoDB Cluster |
dba.getCluster() |
Get handle to existing cluster |
cluster.addInstance() |
Add node to cluster |
cluster.removeInstance() |
Remove node from cluster |
cluster.status() |
Full topology status |
cluster.switchToMultiPrimaryMode() |
Switch to multi-primary |
cluster.switchToSinglePrimaryMode() |
Switch to single-primary |
cluster.setPrimaryInstance() |
Force primary election |
cluster.rescan() |
Re-scan for topology changes |
dba.createClusterSet() |
Create multi-datacenter ClusterSet |
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.

mysqlsh is a skill published in the GitHub repository neverinfamous/mysql-mcp (10 stars, last pushed 3d ago), licensed MIT. It adds 89 tokens to every session and 1,722 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
