What the Splice connector does

The Splice MCP server connects Splice's royalty-free sample catalog to Claude and any MCP-compatible agent. Anthropic's directory lists five tools that search sounds by natural-language description, assemble multi-layer stacks, share them and download samples. Downloads spend subscription credits, so this connector moves money as well as audio.

Splice tools (5)

  • download_asset

Tool names from Anthropic's directory listing. This server requires sign-in, so we could not read tool descriptions or parameter schemas.

Limits

  • The connector spends money and no scope gates it. All four advertised OAuth scopes are identity claims. Nothing at consent separates searching from downloading, so an agent authorised to browse is authorised to spend credits.
  • Splice publishes no tool list. The five names come from Anthropic's directory. Splice's blog states the full list appears only after you connect, and that more tools are coming — so five is a floor, first-party stated.
  • One documented capability is unlisted. Splice advertises stack editing — rename, change BPM, add or remove layers, swap sounds — on two first-party pages, and no listed tool name matches it.
  • We could not read tool schemas or safety annotations. The endpoint returned 401 to an anonymous request, so no parameter-level detail is published here and no tool's own readOnlyHint or destructiveHint is known.
  • Downloads are double-capped. 100 sample downloads per rolling 24-hour period, on top of the monthly credit allowance. On Sounds+ those two numbers are both 100.
  • Search is capped at 50 results and cannot be sorted. Splice documents this for Describe a Sound as a beta limitation, alongside no shuffle.
  • Stacks are capped at eight layers, and building one from a sample needs a loop rather than a one-shot — Splice names the latter as a documented cause of stack-creation failure.
  • Shared stack links are public and have no documented revocation. Recipients keep independent copies of anything they save.
  • Splice's own Terms of Use carry a name-substitution defect. The document published at splice.com/terms, last updated 2026-07-24, refers to the company as "DCI" throughout — 278 occurrences against 15 of "Splice", including a copyright@DCI.com address and a reference to "the DCI website at DCI.com". Splice's privacy policy on the same host does not do this. The clauses are legible and we have cited them as written, but the governing document names an entity that does not match the brand.
  • Not available in ChatGPT, per Splice, despite the directory's general MCP transport.
  • The whole server is beta. Splice labels the MCP server, and the Describe a Sound feature behind it, as beta.
  • Do not confuse this with Splice CAD. An unrelated @splice-cad/mcp package on npm serves a wire-harness CAD tool. It is a different company and a different server.

Frequently asked questions

Does downloading a sample through the Splice MCP server cost credits?

Yes. Splice documents that downloading a new sample through the MCP server costs 1 credit and that re-downloads are free. Credits come from your subscription — 100 a month on Sounds+, 200 on Creator, 500 on Creator+. An agent calling the download tool is therefore spending a metered subscription balance, not just moving a file.

What can I legally do with a sample an AI agent downloaded from Splice?

The same things you could do with any Splice download. Splice grants a perpetual, non-exclusive, royalty-free licence to use the sample commercially inside a new recording or creative work, and that licence survives cancelling your subscription. The route the download took does not change the grant, because the licence attaches at download.

Can I use Splice samples downloaded by an agent to train an AI model?

No. Splice's Terms of Use prohibit using Sounds as source or training material for generative or other artificial intelligence models, and the licensing FAQ repeats it. This restriction is worth noticing precisely because the connector puts the catalog inside an AI tool, where the samples land in an AI workflow by default.

Is a Splice stack built by an agent something I can release?

Not on its own. Splice's Terms of Use state that a stack is not itself a new recording or creative work, though a stack combined with other sounds in a music production may be. So the licence covers what you build from the stack rather than the stack as delivered, and exporting one still spends credits on its samples.

What OAuth permissions does the Splice MCP server request?

Four, and none of them is a capability. Splice's resource descriptor and authorization server both advertise openid, profile, email and offline_access, which are OpenID identity claims. There is no scope separating searching the catalog from spending credits, so consenting to search consents to downloads too.

How many samples can the Splice MCP server download in a day?

One hundred. Splice documents a cap of 100 sample downloads per rolling 24-hour period through the MCP server, separate from your monthly credit allowance. Because the window rolls rather than resetting at midnight, capacity returns gradually across the day rather than all at once.

Who can open a Splice stack shared by an agent?

Anyone with the link, including people without a Splice account. Splice documents shared stack links as public and playable in a browser by anyone. Registered users can save a copy to their own library, and that copy is independent — their edits do not touch your stack, and yours do not touch theirs.

Do I need a paid Splice plan to use the MCP server?

Only for downloads. Splice states that free accounts can search the catalog and build stacks, and that saving sounds to your computer requires a Sounds+, Creator or Creator+ subscription. Free users also get a narrower licence: Splice states their stacks are for promotional, non-commercial use only.

Does the Splice MCP server work with ChatGPT?

Not at this time, according to Splice. Splice's support article and its MCP product page both answer the ChatGPT question with that phrase. The endpoint is an ordinary streamable-HTTP MCP server with OAuth, so the limitation is stated by Splice rather than visible in the protocol.
