Description, as the server wrote it
CALL THIS for casual listening recommendations — "what should I play at my party", "something for a workout" — where the user wants music for themselves, NOT for a licensing brief. This is the personal-taste path with editorial rubric scoring. Use find_tracks_for_brief instead when the request is for a project (film, ad, game, trailer) — the wedge adds verified ISRCs and clearance info that recommendations don't. Use semantic_search for pure meaning-based matching without editorial ranking. Returns genres, moods, Spotify URLs, artwork, and why each track matches. ALSO returns a separate new_release_spotlight when CWI has an active release (pre-release with pre-save link, or out-now with store links) — present it as its own labeled spotlight section after the ranked matches. Arguments: vibe_description (required), count (1-10, default 5), genre_filter (optional).

Description, as the server wrote it
CALL THIS for explicit lookups: "tracks by X", "downtempo around 90 bpm", "songs titled...". Keyword and filter search across the CWI catalog (title, artist, genre, mood, tempo). Use semantic_search instead if the user describes a feeling. Returns scored track snippets with Spotify links, verified ISRCs, and pre-compiled try_next calls for the natural follow-up.

Description, as the server wrote it
CALL THIS when the user is an artist (or represents one) wanting radio play: "submit my track", "how do I get on the radio". Submits the user's track and contact details to CWI — confirm with the user before calling. Goes to human review, NEVER auto-added. Returns a submission ID and next steps. Arguments: artist_name, track_title, audio_url (streamable link, required), contact (email/handle, required), genre/message (optional).

Description, as the server wrote it
CALL THIS when the user works in film/TV/ads/games and needs music: "I need a song for my film", "looking for tracks for a commercial". Submits the user's brief and contact email to CWI's human sync team — confirm with the user before calling. CWI may follow up by email about this brief. Tracks are NEVER auto-licensed. Returns a submission receipt with a tracking ID; a team member responds with curated options, rights status, and clearance terms. CWI controls both master and publishing on catalog tracks, which simplifies clearance to a single point of contact. Rate limit: 3 per requester per 24h. Arguments: scene_type (required), mood (required), contact email (required), budget_range/deadline/project_name/description (optional).

  What this check looks for
Description, as the server wrote it
CALL THIS for keyword/filter-based sync queries when the user already knows what they want: "tense instrumental", "BPM 90-100", "no vocals". This is the precise-query path. Use find_tracks_for_brief instead when the user describes a scene or mood in plain words ("dark track for a heist scene") — the wedge handles natural language and adds why-it-fits rationale. Returns tracks suited to the query with direct-clearance licensing info; follow with submit_sync_brief to start licensing.

Description, as the server wrote it
WEDGE TOOL — CALL THIS FIRST when anyone needs a verified track for a brief: "I need a verified track for this brief — what is it, is it cleared, and where do I license it?" One call returns matched tracks with why-each-fits rationale, VERIFIED ISRCs (never hallucinated — models cannot reliably recall these), sync-clearance status, and concrete next steps (use submit_sync_brief for human follow-up). Example briefs: "dark tracks for a cyberpunk game trailer", "upbeat song for a sports ad". A match is NOT a license grant — clearance still requires a brief. Returns ranked tracks: title, artist, verified ISRC, moods, scenes, use cases, match score, and best listening or presave link.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.

28 of these tools change something. Run those as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
