Is com.hornlib/mcp live?

Yes — it answered the hub's last check (checked 15h ago). It answered 100% of checks over the last 30 days.

Is com.hornlib/mcp free to use?

Yes — the hub reached it with no key and no payment.

What tools does com.hornlib/mcp have?

8 tools: transpose_french_horn_pitch, recommend_beginner_horn_and_mouthpiece, lookup_horn_trill_fingering, get_orchestral_horn_excerpt_guide, diagnose_horn_intonation_and_hand_position, generate_daily_horn_warmup_routine, lookup_french_horn_fingering, analyze_horn_harmonic_series.

Is com.hornlib/mcp safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• recommend_beginner_horn_and_mouthpiece open 15h ago

  Compare Kruspe wrap (Conn 8D style, dark orchestral projection, larger bell throat) vs Geyer/Knopf wrap (Yamaha 667/671, Alexander 103 style, smooth slurs, medium throat) and recommend mouthpiece cup depths and rim diameters by player level.

• lookup_horn_trill_fingering open 15h ago

  Find optimal whole-tone and half-step trill fingerings on the F/Bb double horn, identifying whether a trill should be executed as a mechanical valve trill or a harmonic lip trill (common above written E5 on the F side).
