Best for agents that need music data — catalog search, artist lookup, sync licensing, live radio.
Post-Trap Futurism — machine-readable AI learning surface for That Boy Hi Hat and the Cumulative Web Inc roster.
Installation
Connect in one command:
claude mcp add --transport http cwi https://cwi-machine-data.hp-ace.workers.dev/mcp
No login, no API key, no signup. The server speaks MCP Streamable HTTP (JSON-RPC 2.0) at /mcp. Every response carries X-CWI-License headers; commercial model training or redistribution requires a license — contact hp@cumulativeweb.com.
Verify it works — ask your agent: "Search the CWI catalog for cyberpunk rap." You should get "Cyberpunk 2027" by That Boy Hi Hat as the top result.
Tools
28 tools. Most are read-only; 6 write tools (song requests, airplay submissions, sync briefs, playlist pitches, featured nominations, event RSVPs) are human-reviewed and rate-limited (3 per requester per 24h). None require auth.
| Tool | What it does |
|---|---|
search_catalog | Keyword + filter search across the CWI catalog (title, artist, genre, mood, BPM). Scored engine: title 3x, genre 2x, mood/context/lane 1x. Returns top 5 with matched terms. |
get_track | Full record for one track by title or ID: credits, genres, moods, tempo, licensing status, links, artwork. Usually follows a search_catalog hit. |
get_artist | Artist profile + full track list. Use for artist deep-dives. |
sync_search | Music-supervision search over the editorial sync catalog: moods, energy words, scenes, use-cases ("fight scene", "neon city"). Descriptors are curated by CWI Sync; BPM values are estimates. |
semantic_search | Natural-language catalog search ("rainy night drive, nostalgic") — cosine similarity against 384-dim bge-small-en-v1.5 embeddings, embedded at request time via Workers AI. |
get_graph | The catalog knowledge graph: node/edge counts, node types (tracks, artists, releases, genres), sample nodes. |
get_release | Evidence-tiered, hash-stamped fact packet for a release: tracklist, date, credits, platform links. Omit id for the latest release. |
get_radio | Live Cumulative Radio 365 state: HLS stream URL, now-playing (track, artist, artwork, slot, track end time), listener counts, station metadata. |
