Comprehensive Model Context Protocol server for managing Home Assistant through AI assistants.
Nothing to run from here
StringSpec is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
Lab measurements of nearly 800 tennis strings: search, compare and get recommendations.
Quickstart

claude mcp add --scope user --transport http stringspec-mcp https://stringspec.com/mcp
# 2 — ask your agent for something these tools do

StringSpec costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
Claude Codedeclared by this listing
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http stringspec-mcp https://stringspec.com/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it answers at its publisher’s own address: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
What you approve
4 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

Search 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 th
| Parameter | Type | Required | Notes |
|---|---|---|---|
| query | string | no | Words from the string's name, e.g. "alu power", "hyper-g", "rpm blast". |
| brand | string | no | Brand name, e.g. "Babolat", "Luxilon", "Solinco". |
| material | string | no | Construction family. Polyester is the stiff spin-friendly monofilament; Nylon covers synthetic gut and multifilaments; Gut is natural gut. |
| gauge | string | no | Gauge label. A higher number is thinner, and an "L" gauge is thinner than its base (17L is thinner than 17). |
| sort | string | no | popular (a retailer's units-sold order, default), softest, stiffest, most_spin, best_tension_hold, most_power (energy return), cheapest. |
| max_price_usd | number | no | Only strings with a retail set price at or under this, in USD. Strings without a price are excluded when this is set. |
| include_discontinued | boolean | no | Include strings no longer sold (default false). |
| limit | integer | no | How many to return (default 10). |
Everything 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 an
| Parameter | Type | Required | Notes |
|---|---|---|---|
| name | string | yes | The string's name, e.g. "Luxilon ALU Power 16L" or "RPM Blast". |
Side-by-side measurements, percentiles, prices and buy links for 2 or 3 strings by name, with the StringSpec comparison page when there are two.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| names | array | yes | Two or three string names. |
Rank 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, fr
| Parameter | Type | Required | Notes |
|---|---|---|---|
| need | string | yes | The main thing the player wants. |
| also | string | no | An optional second need, weighted lower than the first. |
| pattern | string | no | String pattern: open (16x19 or more open) or dense (18x20 or tighter). |
| head | string | no | Head size: small (under 98 sq in), mid (98-100), large (100 and up). |
| frame | string | no | Frame feel: flex (flexible, arm-friendly), avg, stiff (stiff and powerful). |
| avoid | string | no | gut (no natural gut), poly (no polyester), polyonly (polyester only). |
| limit | integer | no | Shortlist length (default 8). |

No rule-by-rule report on file for this release
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
This listing is an address its publisher runs, and you connect to it directly — this marketplace is not in the path. The scanner reads packages and public source, and an address is neither: the repository linked on this page is where this record was collected from, not a copy of what the address serves, so it is not graded in its place. So there is no grade — not a withheld one, an unmeasured one.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish StringSpec can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
