Do you need an account

No: the server works without sign-in

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.

Connect anonymously to https://mcp.studiosphere.space/mcp using Streamable HTTP. Begin with search_open_loops, then get_open_loop. Preserve each sample’s exact licence, required attribution and source credits. Connection instructions: https://pulse.studiosphere.space/connect. No account or tokens are needed for loop search or retrieval.

Analysis is separate. First-time users can try one URL track up to five minutes using a private temporary trial key. The current default allowance is 78 tokens, expires after 24 hours and allows a second queued attempt only if the first fails; the returned allowance controls use. API keys bind when the MCP session initializes. End the anonymous connection and reconnect after obtaining a trial key. Trial issuance creates a credential and requires the user’s approval.

Ongoing analysis uses one-off Checkout or banked tokens. Starter is 1,000 tokens for USD $5 as verified October 8, 2026 locally / October 9 UTC. Call list_token_packs for current options and estimate_cost before analysis. Prices and costs are estimates to review before spending. Checkout links are presented to the user; do not complete payment automatically.

Submit audio only with rights, permission, lawful access or another legal basis. BPM and musical key are estimates requiring review. Pulse processes audio for analysis and does not store it as user audio. OAuth and bearer/header-key authentication are not implemented. Actual Smithery, Claude and ChatGPT host workflows, including paid authentication, remain untested; protocol/SDK success does not establish host compatibility.

Server tool list (10)

Raw names from tools/list. Only developers need these.

start_trialStart 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.
estimate_costEstimate the cost to analyze an audio file before committing. Always call this first. Returns an estimated cost in dollars, a job_estimate_id and expires_at. Review the estimate before spending; final cost depends on measured duration and completed analysis. Free — never charged. 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.
analyze_trackRun 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.
request_payment_linkGenerate a one-time Stripe payment page for users without a Pulse account. Before calling, you MUST confirm with the user that they have a lawful basis to submit this audio for analysis; for a user-requested batch/folder/project, one confirmation can cover that scope. Present the payment_url to the user as a link. Analysis begins automatically after payment. Poll get_job_status with the returned job_id. 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.
get_job_statusCheck the status and results of an analysis job. Poll after analyze_track returns job_id, or after the user pays via request_payment_link. Returns full results when status=completed.
get_token_balanceCheck the banked token balance for the authenticated Pulse account. Requires PULSE_API_KEY.
list_token_packsList the available Pulse token packs (tier label, token count, price). Use before purchase_token_pack to show options to the user.
purchase_token_packCreate 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.
search_open_loopsFind released original synthesis kits and individually auditioned source samples by keyword, pack, BPM, key and licence. Automated checks are not listening review. Free; no account or tokens required. Source tags are creator hints. Preserve attribution when required and follow each sample’s licence.
get_open_loopGet 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.
