hermes-agent	15906893c0	Add audiobookshelf-mcp package Go binary from michaeldvinci/audiobookshelf-mcp (v0.0.5). Covers libraries, audiobooks, podcasts, authors, collections, playlists, and users. Uses buildGoModule with fakeHash placeholders to be filled on first nix build.	2026-07-04 22:24:46 +00:00

Covers sources, media items, media profiles, tasks, and settings endpoints. Tested against live Pinchflat instance — 28 sources, search, app info all working via stdio transport.	2026-07-04 22:05:12 +00:00

hermes-agent	87e2b844e8	fix: use fetchFromGitHub instead of fetchPypi for applemusic-mcp NixOS Configuration CI / Nix Flake Check (push) Failing after 17s Details fetchPypi with pyproject format was causing "Unsupported format pyproject" error. Switched to fetchFromGitHub to match the pattern used by other packages in this repo (e.g. zotero-mcp). Note: the SRI hash is a placeholder — run `nix build .#applemusic-mcp` and replace with the correct hash from the error output on first build.	2026-06-25 16:11:06 +02:00
