StudioSphere Pulse — Audio Intelligence

notpaulb/studiosphere-pulse-mcp

Exposes BPM detection, musical key analysis, and waveform peak extraction over MCP for authorized public audio URLs and direct uploads. Runs on Streamable HTTP transport at mcp.studiosphere.space, authenticated by API key in the query string. The server surfaces nine tools including cost estimation, trial key minting, job polling, and Stripe-based token purchasing. Audio is processed in memory and never stored as user content. Payment is per-second of analyzed audio with tool-specific multipliers, starting at free estimates and a single trial analysis before moving to banked tokens or anonymous Checkout. Useful for DJ set planning, sample-pack tagging, DAW prep, and music-library enrichment where you need structured metadata without sending files to a black box.

Parameters* required

include_waveform_databoolean

Optional. Defaults to false so chat agents receive a compact waveform summary plus result_url. Set true only if raw waveform samples are needed.

include_waveform_imageboolean

Optional. Defaults to true. When the job has waveform data, include a server-rendered PNG as MCP image content so the client can display it without fetching a URL.

job_id*string

The job_id returned by analyze_track or request_payment_link.

StudioSphere Pulse — Free Loops and Audio Intelligence MCP

Current workflow evidence is maintained in the compatibility matrix. On October 29, 2026, one approved production SDK trial completed the 180-second CC0 demo through keyed reconnection, analysis, results and fresh anonymous saved-job recovery. All three tools were cache hits. This verifies trial delivery and recovery, not fresh detector execution or an LLM-host workflow. See the redacted trial report.

Discover free, licensed loops and analyze authorized audio for BPM, musical key and waveform data. Start with free discovery and see estimated costs before paid analysis.
