StudioSphere Pulse — Audio Intelligence MCP Server

Get a released sample’s metadata, exact licence, attribution, preview and WAV download URLs. Free; no account or tokens required. Keep attribution when using the sample in a song.

Find original synthesis kits and individually auditioned source samples by keyword, pack, BPM, key, role, review_basis and licence. project_bpm with bpm_tolerance (default 5) returns closest-tempo candidates and project_match reasons; do not combine it with bpm_min/max. Project keys need explicit mode. Optional include_unkeyed_percussion includes percussion hints with unspecified key, requiring audition; this is not proof of harmonic fit. Automated checks are not listening review. Free; no account or tokens required. Keywords match any term; read search_match.missing_terms before claiming a full match or genre. Key abbreviations such as Am are accepted; hard filters stay exact. Source tags are creator hints. Preserve attribution when required and follow each sample’s licence.

Check the banked token balance for the authenticated Pulse account. Requires PULSE_API_KEY.

List the available Pulse token packs (tier label, token count, price). Use before purchase_token_pack to show options to the user.

Run audio analysis on a public audio URL. Requires estimate_cost to be called first (job_estimate_id). Requires PULSE_API_KEY. Before calling, you MUST confirm with the user that they have a lawful basis to submit this audio for analysis. For a user-requested folder, project, playlist, or batch, one confirmation can cover every track in that scope. Returns job_id — poll get_job_status for results. If processing or payment returns estimate_pricing_changed, get a fresh free estimate with estimate_cost, present the new price, and wait for explicit user approval before processing or payment. Never silently retry analysis or purchase.

Estimate audio analysis cost anonymously and free before committing. Read analysis_options for eligible anonymous one-off Checkout, trial duration fit and key-based banked-token use; these do not verify balance or trial entitlement. Eligible quotes can include checkout.upfront_payment_estimate from the current charge builder; this is not a reserved price or a saved-link charge. Review the hosted amount before payment. Returns estimated dollars, job_estimate_id and expires_at. Review the estimate before spending; final cost depends on measured duration and completed analysis, and Checkout can collect a buffered amount with refund thresholds. If processing or payment returns estimate_pricing_changed, get a fresh free estimate, present the new price, and wait for explicit user approval before processing or payment. Never silently retry analysis or purchase.

Resume the original saved job anonymously after interruption. Follow continuation for human payment, bounded polling, result review or support; never create a replacement purchase. Completed/partial results may include studio_notes: preserve provenance, warnings and failed tools; BPM/key are estimates requiring review. Keep job references private. Results, costs and notes are not payment/refund confirmation. refund_status_source=local_ledger is reconciliation at refund_checked_at, not a fresh provider query; unconfirmed/needs_review is not a completed refund. Review terminal Checkout billing separately on the result page or the on-demand REST receipt_api_url; that URL is not another MCP tool.

Create a Stripe Checkout session for a Pulse token pack. Returns payment_url — DO NOT submit it programmatically; surface it to the user so they can complete payment in their browser. Once paid, banked tokens are credited automatically. Requires PULSE_API_KEY.

Create anonymous one-off Checkout after an estimate, explicit human link-creation approval and lawful-basis confirmation. Read analysis_options.checkout. The human reviews the hosted upfront amount and pays; it can exceed analysis cost. Save job_id, payment_url and continuation.review_url privately; lost links require support, not a replacement purchase. For minimum_charge_offer, show minimum final cost and upfront estimate, obtain explicit acceptance, then send accept_minimum_charge:true and max_upfront_amount_cents at the approved ceiling. Rights alone do not approve spending. On estimate_pricing_changed, get a fresh free estimate and explicit approval. An exceeded cap needs new review; never raise it or retry automatically. Poll the original job with get_job_status after payment or interruption. Host setup/recovery: https://pulse.studiosphere.space/connect

Start a temporary, email-free Pulse trial for one URL analysis. Read trial_policy and trial_allowance for the actual duration cap and remaining attempts; an existing trial key may have a lower cap. One completed/partial analysis consumes the allowance regardless of remaining tokens. A failed analysis may retry only when attempts remain. No Stripe Checkout session is created. Store the returned private API key in the client or a trusted local environment; never repost it in logs, screenshots, shared chats or issues. Confirm rights, permission, lawful access, or another legal basis before analysis. The original CC0 demo is https://pulse.studiosphere.space/assets/pulse-demo.mp3 (180 seconds); use it only if it fits the returned cap.
