compare_strings
ClaudeSide-by-side measurements, percentiles, prices and buy links for 2 or 3 strings by name, with the StringSpec comparison page when there are two.
Overview
StringSpec puts the measurements of nearly 800 tennis strings inside Claude. Every string was tested on the same machine under the same protocol, so the numbers compare fairly: string bed stiffness, how much tension it loses, how much energy it returns, spin potential, ball bite, string friction and how far it stretches under load. Each figure comes with its percentile across the whole database, so "is this soft?" has a real answer. Ask about one string and get every measurement, an estimated playable life, a tension adjustment versus your usual, and how it ranks for spin, comfort, control, power, tension hold, durability and feel. Compare two or three strings side by side. Describe what you want and your racquet (string pattern, head size, frame stiffness) and get a ranked shortlist with the reason each string fits, using the same finder as stringspec.com. Search and sort the database by brand, material, gauge, any measurement or price. Answers keep measurements and estimates apart, carry a retailer's set price with the date it was checked, and link the string's page on stringspec.com for the full charts. The connector is read-only and needs no account.

get_string
ClaudeEverything StringSpec has on one string, found by name (misspellings and missing gauges are fine): every measurement with its database percentile, elongation at 40, 51 and 62 lb, an estimated playable life, a tension adjustment versus the player's usual, how it ranks for each playing need (spin, comfort, control, power, tension hold, durability, feel), the closest alternatives, the retail price and a buy link. When the name matches several strings it returns the best match and lists the others.
recommend_strings
ClaudeRank the database for what a player wants, with StringSpec's string finder: one main need and an optional second one (spin (More spin and shape), comfort (Easier on my arm), control (More control, less launch), power (More power and depth), hold (Plays the same for longer), durable (Lasts longer before it breaks), feel (Best feel and touch)), adjusted for the racquet (string pattern, head size, frame stiffness) and with a material ruled out if asked. Returns a shortlist with a 0-100 fit, why each string fits, its price and buy link, and the finder link with the same answers filled in. For arm or elbow pain use need "comfort", and avoid "poly" when the player wants no polyester.
search_strings
ClaudeSearch 791 lab-measured tennis strings by name, brand, material and gauge, sorted by a measurement or by price. Each result carries stiffness (lb/in), tension loss (%), energy return (%), spin potential, ball bite and string friction, each with its percentile in the database, plus the current retail price, a buy link and the StringSpec page. Returns at most 10 strings; narrow the filters rather than asking for more.
