SeedreamMCP

seedream_edit_image

Modify existing images with text prompts: change styles, backgrounds, colors, clothing, or perform virtual try-on. Supports single or multiple inputs and returns edited image URLs.

Instructions

Edit or modify existing images using ByteDance's Seedream/SeedEdit model.

This tool modifies existing images based on text instructions. It can change
styles, backgrounds, attributes, clothing, and more. Supports single or
multiple image inputs.

Use this when:
- You want to modify or transform an existing image
- You need to change style, background, colors, or attributes
- You want to apply artistic transformations (watercolor, oil painting, etc.)
- You need virtual try-on (clothing on person)
- You want to place objects in different scenes

Common use cases:
- Style transfer: "Convert to anime style", "Make it look like a pencil sketch"
- Background change: "Replace background with a sunset beach"
- Attribute edit: "Change hair color to blonde", "Add sunglasses"
- Virtual try-on: Provide person image + clothing image
- Scene composition: Place products in realistic environments

Returns:
    JSON with task_id, trace_id, success status, and edited image data
    including image URLs.

TDQS

A3.8/5.0

Behavior3/5

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

No annotations are provided, so the description carries the full burden, and it does disclose the return payload (task_id, trace_id, success, image URLs), watermark defaulting to true, and the PNG constraint for transparent background. However it never says whether the call is synchronous or asynchronous (the mere existence of callback_url implies async), nor mentions permissions, cost, latency, or failure modes for a 13-parameter generation job.

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

Conciseness3/5

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

Purpose and scope are front-loaded, which is good, but the 'Use this when' bullets and the 'Common use cases' bullets substantially restate the same ground (style, background, attributes, virtual try-on), so several sentences do not fully earn their place. Structure is readable but repetitive.

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

Completeness4/5

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

With 13 parameters, an output schema already present, and 100% schema coverage, the description supplies what structured fields cannot: the intent-level taxonomy of edits and multi-image input semantics. The main remaining gap is async/execution behavior, but for a tool of this complexity the description is largely complete.

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 description coverage is 100%, so the schema already documents size, model, background, output_format and the rest; the description only adds illustrative prompt examples ('Make the person wear a red dress'). Per the coverage rule this is a baseline 3, and the description does not add much beyond the schema for the remaining parameters.

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?

States a specific verb and resource ('Edit or modify existing images') and immediately scopes it to image-to-image transformation driven by text instructions. The framing as modification of an existing image implicitly but clearly separates it from the sibling seedream_generate_image, and an agent can tell which one to pick without opening a schema.

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

Usage Guidelines4/5

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

A dedicated 'Use this when' block plus five concrete use-case bullets give strong positive guidance (style transfer, background change, attribute edit, virtual try-on, scene composition). It never names an alternative tool or states a when-not condition (e.g. use generate_image when no source image exists), so it stops short of 5.

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