What your chats can do
6 tools from Splice MCP.
- Create stackCreate a stack from an existing sample. This is the ONLY tool that can use a previously found or selected sample as a seed — if the user wants to build a stack around a specific sample, you MUST use this tool (not prompt_to_stack). ROUTING RULE: Any request like 'create a stack from this sample', 'build around this loop', 'use this as a seed', or referencing a specific asset UUID MUST use this tool. The seed sample MUST be a loop (not a one-shot). If the user asks to build a stack from a one-shot, do NOT silently search for loops. Instead, FIRST explain to the user that one-shots cannot be used as stack seeds because stacks require loopable samples to layer together, THEN offer to find similar loops that match the style or character of the one-shot they liked. Uses the loop as the starting layer and generates a full multi-layer stack of compatible samples around it.
- Describe a soundSearch the Splice catalog for sounds matching a natural language description. Returns sample metadata including BPM, key, tags, duration, and Splice links. Use this to BROWSE and EXPLORE individual sounds -- when the user wants to find, preview, or discover specific samples, loops, or one-shots. Do NOT call this tool alongside prompt_to_stack for the same request. If the user wants a complete multi-track beat or arrangement, use prompt_to_stack instead. Present ALL results to the user exactly as numbered; do not filter, omit, or reorder any results — let the user decide which sounds are relevant. IMPORTANT: One-shots CANNOT be used as seeds to create stacks — only loops can. If the user searched for one-shots and then asks to create a stack from those results, you MUST explicitly tell the user that one-shots cannot be used to create stacks and offer to search for similar loops instead. Do NOT silently pivot to loops.
- Download assetPurchase and get a presigned download URL for a sound from the Splice catalog. The server returns a presigned URL — it does not write files. If the client has local filesystem access, it should fetch the URL and save the file to download_path; otherwise omit download_path and present the URL to the user. IMPORTANT: The first time an asset is downloaded it spends one of the user's credits. Subsequent downloads of the same asset are free. Always confirm with the user before calling this tool. The URL expires quickly — always display the file name alongside the download URL so the user can identify and access their file.
