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 | $0.00037 | $0.00522 |
| Opus 5 | $0.00018 | $0.00261 |
| Sonnet 5 | $0.00007 | $0.00104 |
| Haiku 4.5 | $0.00004 | $0.00052 |
Grade A, and why
alloydb-postgres-optimize 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 10d 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
83% identical to cloud-sql-postgres-view-config — 19 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 — 89 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
database_overview
Fetches the current state of the PostgreSQL server, returning the version, whether it's a replica, uptime duration, maximum connection limit, number of current connections, number of active connections, and the percentage of connections in use.
get_cluster
Retrieves details about a specific AlloyDB cluster.
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| project | string | The GCP project ID. This is pre-configured; do not ask for it unless the user explicitly provides a different one. | No | |
| location | string | The location of the cluster (e.g., 'us-central1'). | Yes | |
| cluster | string | The ID of the cluster. | Yes |
list_available_extensions
Discover all PostgreSQL extensions available for installation on this server, returning name, default_version, and description.
list_installed_extensions
List all installed PostgreSQL extensions with their name, version, schema, owner, and description.
list_memory_configurations
List PostgreSQL memory-related configurations (name and current setting) from pg_settings.
list_pg_settings
Parameters
| Name | Type | Description | Required | Default |
|---|---|---|---|---|
| setting_name | string | Optional: A specific configuration parameter name pattern to search for. | No | `` |
| limit | integer | Optional: The maximum number of rows to return. | No | 50 |
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

alloydb-postgres-optimize is a skill published in the GitHub repository tmolavi/mcp-agent-skills-hub (8 stars, last pushed 14d ago), licensed MIT. It adds 37 tokens to every session and 522 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 83% identical to cloud-sql-postgres-view-config, differing in 19 lines, and is treated as a copy.
