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 | $0.00039 | $0.02106 |
| Opus 5.5 | $0.00016 | $0.00842 |
| Sonnet 5.5 | $0.00008 | $0.00421 |
| Haiku 4.5 | $0.00004 | $0.00211 |
Grade A, and why
cloud-sql-postgres-data 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.
This is a copy
88% identical to alloydb-postgres-data — 208 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 204 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Usage
All scripts can be executed using Node.js. Replace <param_name> and
<param_value> with actual values.
Bash: node <skill_dir>/scripts/<script_name>.js '{"<param_name>": "<param_value>"}'
PowerShell: node <skill_dir>/scripts/<script_name>.js '{\"<param_name>\": \"<param_value>\"}'
Note: The scripts automatically load the environment variables from various .env files. Do not ask the user to set vars unless skill executions fails due to env var absence.
Scripts
execute_sql
Use this tool to execute a single SQL statement.
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| sql | string | The sql to execute. | Yes |
list_indexes
Lists available user indexes in the database, excluding system schemas (pg_catalog, information_schema). For each index, the following properties are returned: schema name, table name, index name, index type (access method), a boolean indicating if it's a unique index, a boolean indicating if it's for a primary key, the index definition, index size in bytes, the number of index scans, the number of index tuples read, the number of table tuples fetched via index scans, and a boolean indicating if the index has been used at least once.
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| schema_name | string | Optional: a text to filter | No | `` |
| : : : results by schema name. The : : : | ||||
| : : : input is used within a LIKE : : : | ||||
| : : : clause. : : : | ||||
| table_name | string | Optional: a text to filter | No | `` |
| : : : results by table name. The : : : | ||||
| : : : input is used within a LIKE : : : | ||||
| : : : clause. : : : | ||||
| index_name | string | Optional: a text to filter | No | `` |
| : : : results by index name. The : : : | ||||
| : : : input is used within a LIKE : : : | ||||
| : : : clause. : : : | ||||
| only_unused | boolean | Optional: If true, only returns | No | false |
| : : : indexes that have never been : : : | ||||
| : : : used. : : : | ||||
| limit | integer | Optional: The maximum number of | No | 50 |
| : : : rows to return. Default is 50 : : : |

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.

cloud-sql-postgres-data is a skill published in the GitHub repository tmolavi/mcp-agent-skills-hub (8 stars, last pushed 1mo ago), licensed MIT. It adds 39 tokens to every session and 2,106 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 88% identical to alloydb-postgres-data, differing in 208 lines, and is treated as a copy.
