PlanetScale Claude Plugin installs a PlanetScale MCP server, which lets Claude Code communicate with PlanetScale, together with database and PlanetScale-specific skills. It is for people using Claude Code with a PlanetScale account and authenticated database features. The catalogue entries are the plugin and skills supplied by this project.
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 | $0.00038 | $0.02151 |
| Opus 5 | $0.00019 | $0.01076 |
| Sonnet 5 | $0.00008 | $0.00430 |
| Haiku 4.5 | $0.00004 | $0.00215 |
Grade A, and why
planetscale-query-insights-and-tags 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 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.
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
100% identical to planetscale-query-insights-and-tags — 0 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 — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Query Insights and tags
Purpose
Use PlanetScale Insights to understand query behavior, then recommend SQLCommenter-compatible tags that make future diagnosis and Traffic Control possible. Do not change database settings or repository code without approval.
What to inspect
Query behavior
For the selected database and branch, inspect:
- Top queries by total time.
- Top queries by time per execution.
- Top queries by rows read.
- Top queries by execution count.
- For Postgres, top queries by CPU usage (
sort=cpuTimeorsort=percentCpuTimeon the Insights API). - Queries with errors.
- Notable queries and active anomalies.
- Query patterns affected by recent deploys.
- Query patterns attached to schema recommendations.
- For sharded Vitess databases, vindex usage for each query pattern: the
percentage of traffic using relevant vindexes and the vindex-usage trend
over time. The API exposes per-pattern
index_usagesandrouting_index_usages; get the trend from the dashboard Vindexes tab or by comparing API windows. Treat missing or declining relevant-vindex usage as an indexing or routing investigation input, not as proof that a new index is required.
Insights API surface
Query Insights is public API: read-only GET endpoints under
organizations/{org}/databases/{db}/branches/{branch}, authorized by a
service token or OAuth token with read_databases/read_database.
/insights— aggregated statistics per query pattern over the requested window. Set the window withfrom/to(ISO 8601) orperiod(for example1h,24h); search SQL patterns withq; sort server-side withsortanddir— sort keys includecount,errorCount,rowsRead,totalTime,cpuTime,ioTime,percentTime,percentCpuTime,p50Latency,p99Latency,maxLatency,egressBytes, and thetrafficControlWarnings/trafficControlThrottledfamily. Filter withtablet_type(primary,replica,rdonly) andtype(SELECT,INSERT,UPDATE,DELETE); trim responses withfields; paginate withpage/per_page./insights/{fingerprint}— individual collected executions for a pattern (timestamps, duration, rows, username, client address, error message). Available regardless of raw query collection; raw collection adds literal parameter values to these records./insights/{fingerprint}/summaryreturns the single-pattern aggregate;/insights/queries/{id}fetches one execution./insights/errors— error fingerprints with counts and messages (qsearches the error message; sort bycount,lastRun,totalTime, ortimePerQuery)./insights/errors/{fingerprint}lists the failing executions behind one error fingerprint./insights/anomaliesand/insights/anomalies/{id}— anomaly windows with per-query correlation coefficients identifying which patterns moved with the anomaly./insights/tags— tag keys with observed values (values_limit,literal_values_only, andfingerprint/keyspacefilters);/insights/tags/{tag}for a single key./insights/tags/summariesgroups the full statistics schema by one or more tag keys via thetagsparameter — use it to attribute load to routes, jobs, or features without client-side aggregation./insights/{fingerprint}/traffic/budgets— the Traffic Control budgets and rules that affect a fingerprint (Postgres).
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.

planetscale-query-insights-and-tags is a skill published in the GitHub repository planetscale/claude-plugin (4 stars, last pushed 10d ago), licensed Apache-2.0. It adds 38 tokens to every session and 2,151 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to planetscale-query-insights-and-tags, differing in 0 lines, and is treated as a copy.
