What our measurements say

com.flightdelayhq/site is a remote MCP server published at flightdelayhq.com. It has been probed 10 times since 9/12/2026. It answered in 10 of them (100.0%), a near-uninterrupted record. Median response time is 685 ms, a delay an agent will notice. It offers a narrow, focused set of 10 tools. On the protocol side it still runs 2025-11-25 and has not moved to the newer spec.

Agent readability score

Can an LLM agent pick the right tool here — names, descriptions and parameter clarity are assessed.

Agent readability score

Tools are functional but lack clarity and consistency in naming and error handling.based on measured tool list

Strengths

Tool names are generally descriptive and align with their purposes (e.g., dataset_search, dataset_compare).
Some descriptions explicitly state use cases (e.g., 'for "X vs Y" questions' in dataset_compare).

Weaknesses

Descriptions often omit specific constraints or error scenarios (e.g., submit_enquiry's description is cut off).
Parameter explanations are minimal (e.g., 'confirmation' in submit_enquiry lacks context).
Tool overlap exists (e.g., dataset_search vs. dataset_row for data retrieval).

submit_enquiry — Description is cut off, leaving critical details (e.g., error handling) unexplained.
dataset_row — Name is generic and could be confused with other row-related tools (e.g., dataset_search).
dataset_compare — Description mentions 'X vs Y' but lacks examples of when this tool is preferred over others.

Verdict

The tools are functional but suffer from inconsistent documentation, overlapping purposes, and missing error details. A score of 65/100 reflects these limitations while acknowledging clear naming in some cases.

Tools the server advertised in the latest measurement — measured, not catalog-claimed.

dataset_columns0 params
The columns, which of them are numeric, the row count and the provenance banner of the FlightDelayHQ dataset. Call this first to learn the schema.
dataset_search2 params · 1 required
Rows of the FlightDelayHQ dataset whose cells contain the query (case-insensitive), up to 50.
- querystringrequired
- limitinteger
dataset_row2 params · 2 required
The rows of the FlightDelayHQ dataset where a column equals a value exactly (case-insensitive).
- columnstringrequired
- valuestringrequired
dataset_compare2 params · 2 required
The rows of the FlightDelayHQ dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
- columnstringrequired
- valuesarrayrequired
dataset_stats1 param · 1 required
count, min, max, mean, median and sum of a numeric column of the FlightDelayHQ dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
- columnstringrequired
dataset_top3 params · 1 required
The highest (or lowest) rows of the FlightDelayHQ dataset by a numeric column — "which is the most/least X".
- columnstringrequired
- limitinteger
- ascendingboolean
dataset_provenance0 params
The source, the date it was computed, the licence and the citation for the FlightDelayHQ dataset. Read this to attribute a figure correctly.
enquiry_describe0 params
Read first. States plainly what submit_enquiry does on FlightDelayHQ: 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.
enquiry_fields0 params
Every field of the FlightDelayHQ 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.
submit_enquiry3 params · 2 required
Submits an enquiry to FlightDelayHQ — 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 FlightDelayHQ may reply to your question by email. We do not sell your details to anyone."
