DogsLife turns a dog's age and your day into a plan, with six read-only tools. Potty schedule (8 to 52 weeks): how long the puppy can usually hold it, how often to go out, whether to plan night trips, and a sample day with clock times. Sleep needs (8 weeks to 24 months): typical sleep per 24 hours, how much the night covers, and how many hours of naps are left. Walks and exercise (8 weeks to 20 years): daily minutes for the dog's age, size and energy. Feeding schedule (8 weeks to 24 months): meals a day, meal times and when to switch to adult food. Adult weight (6 to 18 months): an estimate from age and current weight. Dog age: human years from the AVMA chart (up to 16 years). Same rules and sources (VCA, AKC, PetMD, Agria, Zoetis, Royal Kennel Club, PDSA, AVMA) as the calculators on dogslifeapp.com. Answers in 23 languages, with an interactive day-timeline card (MCP Apps). Read-only, no sign-in, nothing stored. Docs: https://dogslifeapp.com/connect.html

An MCP server for Perigee, the open-source 3D viewer of the artificial objects orbiting the Earth, the Moon and Mars and of the spacecraft crossing the solar system. It lets an AI assistant (a teaching assistant, for example) answer questions such as “how far is Mars from the Earth on 1 December 2026?”, “where is the ISS now?” or “what is Lucy's mission?”, and hand the student a live 3D view, with how each number was obtained, from which data, how fresh and how accurate.

ScanSing reads printed sheet music. Give Claude a PDF or a photo of a score and it gets back MusicXML, the format MuseScore, Sibelius, Finale and Dorico open. It is the recogniser inside the ScanSing app for choir singers, offered as a connector. Once a score is recognised, Claude can answer questions about it without recognising it again: - what the key, time signature, tempo and length are, and each part's range, clefs and lyrics; - one voice on its own, for example just the alto line of a choir piece; - the score or a part moved to another key, with notes respelled for the new key signature; - a MIDI file, one track per part, to listen to or rehearse with; - a short-lived download link to open the result in a browser or notation app. It handles PDFs up to 40 pages and PNG, JPEG, HEIC, TIFF and WebP images, can recognise selected pages of a long PDF, and can split a songbook into one MusicXML per piece. A file can be given as a web link or a small image; in Claude Code, a file on your computer is sent through a one-time upload link. Recognition spends pages from your ScanSing plan, so it is the only tool that is not read-only. Everything else works on the stored result and is free. The first connection with a new email comes with 20 free pages; paid plans start at $9 a month for 300 pages. Scores and results are deleted about an hour after recognition and are never used for training.
