CWI Discovery Engine is the sync-licensing discovery layer for AI agents: natural-language brief in, licensable tracks with verified ISRCs and one-signature clearance out. 29 MCP tools (find_tracks_for_brief leads). For general ISRC metadata lookup, we defer to MusicBrainz — we are the licensable-track discovery layer, not a general database.
Scored across 30 tools
The routing is explicitly signposted (find_tracks_for_brief vs get_recommendations vs semantic_search vs search_catalog vs sync_search vs get_sync_catalog), which saves it from being a 2. Still, seven overlapping discovery tools plus get_featured means an agent must internalize a fairly subtle decision tree, and the sync pair (sync_search vs get_sync_catalog vs find_tracks_for_brief) is genuinely easy to mix up. Entity-detail tools (get_artist/get_track/get_release/get_genre/get_graph) are cleanly separated.
Uniform snake_case with a predictable verb_noun shape (get_track, find_tracks_for_brief, submit_sync_brief, verify_brief_candidates). Minor deviations: bare 'rsvp' and noun-phrase names like 'nominate_featured'/'pitch_for_playlist' break the get_/list_ rhythm slightly, but nothing is unreadable. No camelCase mixing.
30 tools is heavy, but the server genuinely spans four surfaces: catalog/entity lookup, radio state, sync licensing, and fan submissions. Within each surface the count is reasonable, yet the ~7 discovery/search variants are redundant enough that a consolidation pass would meaningfully slim the surface.
Covers read paths for every entity (track, artist, release, genre, label, playlist, video, events, radio now/next/schedule) plus write paths for fan/industry submissions (request_song, rsvp, nominate_featured, pitch_for_playlist, submit_for_airplay, submit_sync_brief). Gaps are secondary: no way to check status of a sync brief or playlist pitch after submission, no cancel/withdraw for an RSVP or request, and no licensing-transaction step beyond handing off to a human.
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.
Inputs: brief (required), limit, explicit. Returns: find_tracks_for_brief response: matched tracks with fit reasons, verified ISRCs…
CALL THIS when the user asks what is new: "any new music", "what is CWI up to", "latest news". Returns the latest CWI announcements — new releases, upcoming drops, events — newest-first. Filter by "releases", "news", or "events".
Inputs: limit, category. Returns: get_announcements response: CWI announcements newest-first.
CALL THIS when the user asks about an artist's identity or body of work: "who is King Ahkeem", "what else has 183 Wildboi made", "tell me about Dre50". Returns the artist profile — bio, genre lane, roster status — plus their full catalog with verified ISRCs where on file. Use get_track when the user asks about one specific song.
Inputs: name (required). Returns: get_artist response: artist profile, catalog list, related graph nodes.
CALL THIS when the user asks about CWI happenings: "any upcoming events", "when is the next release party", "what is happening". Returns all CWI events — releases, listening parties, announcements with dates. Use the event_id with rsvp to RSVP.
Inputs: upcoming_only. Returns: get_events response: CWI events (releases, listening parties, recurring).
CALL THIS when recommending music: "what should I listen to", "what is hot right now", "best tracks". Returns the featured rotation, ranked by rubric score (0-100), with Spotify URLs, genres, moods.

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.

Inputs: date. Returns: get_schedule response: full Radio 365 rotation — every slot with track, artist,…
CALL THIS when the user wants to browse the full licensable inventory — not a specific search, but "show me everything I can license" or "what's in the sync catalog".

Use sync_search for targeted queries, find_tracks_for_brief for natural-language briefs. Chain to submit_sync_brief to start licensing.
Inputs: mood, genre. Returns: get_sync_catalog response: sync-ready tracks with rights and clearance info.

Inputs: name (required), contact (required), event_id (required), plus_ones. Returns: rsvp response: RSVP confirmation with ID. Rate limit: 3 per contact per 24h.
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.
Inputs: q (required), limit. Returns: search_catalog response: scored track snippets plus pre-compiled try_next calls.

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.

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.

NEW WORK — built 2026-10-27 for the Meta Global AI Developer Hackathon. Deterministic verified-brief gate: takes candidate tracks proposed by a caller (for example Muse Spark reasoning supplied by the caller) and returns the gate decision for each against the worker sync catalog data (sync-catalog-data.js, 29 tracks, 27 verified ISRCs). PASS only for a catalog match with a verified ISRC. FLAG for a catalog match without a verified ISRC. DROP for no catalog match (invented or outside the catalog). This tool makes NO Meta API call and holds no Meta key — Spark reasoning is supplied by the caller, the gate is the tool. A match is NOT a license — clearance is direct by Cumulative Web Inc, hp@cumulativeweb.com, one-signature, BMI.
Inputs: candidates (required). Returns: verify_brief_candidates response: one deterministic gate decision per candidate…
