suno_generate_music

Create AI-generated music by describing your desired genre, mood, and theme. Suno automatically generates lyrics, melody, and arrangement based on your prompt.

Instructions

Generate AI music from a text prompt using Suno's Inspiration Mode.

This is the simplest way to create music - just describe what you want and Suno
will automatically generate appropriate lyrics, melody, style, and arrangement.

Use this when:
- You want quick music generation with minimal input
- You don't have specific lyrics in mind
- You want Suno to be creative with the arrangement

For full control over lyrics and style, use suno_generate_custom_music instead.

Returns:
    Task ID and generated audio information including URLs, title, lyrics, and duration.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
promptYesDescription of the music to generate. Be descriptive about genre, mood, instruments, and theme. Examples: 'A happy birthday song with acoustic guitar', 'Epic orchestral battle music with dramatic choir', 'Chill lo-fi hip hop beat for studying'
modelNoSuno model version. 'chirp-v5-5' is the latest and recommended for best quality with 8-minute max duration. 'chirp-v4-5' is a reliable choice for most use cases. Older models (v3, v3-5, v4) have shorter duration limits.chirp-v5-5
instrumentalNoIf true, generate instrumental music without vocals. Default is false (with vocals).
variation_categoryNoVariation intensity for v5+ models. 'high' for maximum variation, 'normal' for balanced, 'subtle' for minimal changes. Only supported in chirp-v5 and above.
callback_urlNoWebhook callback URL for asynchronous notifications. When provided, the API will call this URL when the audio is generated.

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the full burden. It discloses that it auto-generates lyrics, melody, style, and arrangement, and specifies return values (Task ID, audio info). However, it does not mention async behavior, rate limits, or potential costs, which would improve transparency.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise: a brief introductory sentence, three bullet points for usage, a sibling mention, and a return value line. No redundant or rambling content.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool complexity (5 params, output schema exists), the description covers purpose, usage guidelines, behavior, and return format succinctly. It references the sibling tool for advanced needs, making it complete for the intended use case.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with detailed descriptions, examples, and enums for each parameter. The description does not add additional meaning beyond the schema, so a baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool generates AI music from a text prompt using Suno's Inspiration Mode, and explicitly distinguishes it from sibling suno_generate_custom_music, which offers full control over lyrics and style.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description includes a 'Use this when:' section with three specific scenarios (quick generation, no specific lyrics, want creative arrangement) and directs users to an alternative for full control, providing clear when-to-use and when-not-to-use guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
