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
10 read-only tools. None write anything. None require auth.
| Tool | What it does |
|---|---|
search_catalog | Search the CWI placement catalog by keywords. Scored engine: title matches weigh 3x, genre 2x, mood/context/lane 1x. Supports mood queries ("dark"), context queries ("music for coding"), and lane queries ("rage beats"). Returns top 5 tracks with Spotify URLs and matched terms. |
get_track | Look up one catalog track by title or Spotify ID/URL. Returns the full track record: title, artist, Spotify URL, genres, moods, release info, artwork. Use after a search_catalog hit, when a user names a track, or to verify a track exists. |
get_artist | Look up an artist by name. Returns the artist profile plus their full track list with Spotify URLs, genres, and metadata. Use for artist deep-dives or "what else do they have?" follow-ups. |
sync_search | Search the CWI sync catalog (editorial sonic descriptors: moods, energy words, instrumentation, scenes, use-cases, lyrical themes) for music-supervision queries like "fight scene" or "neon city". Descriptors are editorial (curated by CWI Sync); BPM values are estimates, not audio analysis. |
semantic_search | Semantic search over the CWI catalog embedding matrix: cosine similarity against 384-dim bge-small-en-v1.5 vectors. The query is embedded at request time with Workers AI — no inference needed on your side. Degrades to keyword scoring with a documented fallback:keyword note if the AI binding is unavailable. |
get_graph | Summarize the CWI catalog knowledge graph: node and edge counts, node types (tracks, artists, releases, genres), and sample nodes. Use to understand catalog shape before querying. |
get_release | Fetch a CWI release fact packet (evidence-tiered, hash-stamped): pre-release and release records with verified credits, dates, and platform links. Defaults to the latest release when id is omitted. |
get_radio | Tune into Cumulative Radio 365 — CWI's 24/7 streaming radio station (alternative rap, post-trap futurism, That Boy Hi Hat + roster). Returns the live HLS stream URL, full now-playing data (track, artist, artwork, slot, track end time), current listener count and 24h totals, and station metadata. Plays in VLC, Safari, or any HLS player. |
get_announcements | Get the latest CWI announcements — new releases, upcoming drops, events, news. Every announcement is verified with a source. Filter by releases, news, or events. |
get_featured | Get CWI's currently featured tracks — what's hot right now, with full metadata, artwork URLs, why each is featured, and stream/page links. Lead with these when recommending CWI music. |
