Scored across 10 tools
The dataset tools are mostly distinct: schema, provenance, exact row lookup, free-text search, multi-value comparison, statistics, and ranking each have clear purposes. However, dataset_row and dataset_compare both retrieve rows by column value and could be confused without careful reading, though the descriptions clarify the exact-equality versus ordered-multi-value distinction.
All tool names use consistent snake_case and clear grouping prefixes: dataset_* for data operations and enquiry_* for the enquiry workflow. The only slight deviation is submit_enquiry, which is verb_noun while most others are noun-style, but it still fits the established prefix convention.
Ten tools is well-scoped for a dataset-query plus enquiry-submission server. The dataset surface is broken into focused query tools, and the enquiry workflow is covered by three cohesive tools rather than a sprawling set.
The dataset side covers schema discovery, provenance, exact lookup, search, comparison, aggregation, and ranking, which is comprehensive for answering questions about a static tabular dataset. The enquiry side covers explanation, field discovery, and a safe two-step submission flow, leaving no obvious dead ends.
The columns, which of them are numeric, the row count and the provenance banner of the VPNCompareHQ dataset. Call this first to learn the schema.
Inputs: no named parameters.
The rows of the VPNCompareHQ dataset whose column is any of the given values, in the order given, for "X vs Y" questions.
Inputs: column (required), values (required).
The source, the date it was computed, the licence and the citation for the VPNCompareHQ dataset. Read this to attribute a figure correctly.
Inputs: no named parameters.
The rows of the VPNCompareHQ dataset where a column equals a value exactly (case-insensitive).
Inputs: value (required), column (required).
Rows of the VPNCompareHQ dataset whose cells contain the query (case-insensitive), up to 50.
Inputs: query (required), limit.
count, min, max, mean, median and sum of a numeric column of the VPNCompareHQ dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
Inputs: column (required).
The highest (or lowest) rows of the VPNCompareHQ dataset by a numeric column: "which is the most/least X".
Inputs: column (required), limit, ascending.
Read first. States plainly what submit_enquiry does on VPNCompareHQ: it starts an enquiry with human providers who quote directly. Nothing is bought, ordered or paid; no quote is guaranteed; it is free. Also returns who receives the details, the consent wording, and how the person confirms.
Inputs: no named parameters.
Every field of the VPNCompareHQ enquiry: key, label, type, whether required, help text and the allowed options where there are any. Pass answers to submit_enquiry keyed by field key.
Inputs: no named parameters.
Submits an enquiry to VPNCompareHQ: NOT a purchase, NOT a guaranteed quote. Step 1: call with the answers (keyed by field key from enquiry_fields) and consent=true; it validates and returns a summary, the consent line and a confirmation token; show the person the summary and the consent line. Step 2: only if the person agrees, call again with the same answers, consent=true and the confirmation token; the enquiry is then submitted, and the person receives an email with a link they must click before any provider sees it. Consent means the person has read and agreed to: "By submitting you agree VPNCompareHQ emails you a recommendation and shares nothing else with anyone."
Inputs: answers (required), consent (required), confirmation.
