Amazon Bedrock MCP Server のツール

Generate image(s) using Amazon Nova Canvas model. The returned data is Base64-encoded string that represent each image that was generated.

概要

What is Amazon Bedrock MCP Server?

A Model Context Protocol (MCP) server that integrates with Amazon Bedrock’s Nova Canvas model to generate high-quality images from text descriptions. It is intended for developers building AI‑powered image generation workflows via MCP‑compatible clients like Claude Desktop.

How to use Amazon Bedrock MCP Server?

Install via npx or clone the repository, configure AWS credentials (environment variables, credentials file, or IAM role), and set up the server in your MCP client’s configuration file. The server exposes a single tool generate_image which accepts parameters such as prompt, negativePrompt, width, height, quality, cfg_scale, seed, and numberOfImages.

Key features of Amazon Bedrock MCP Server

Text‑to‑image generation using Amazon’s Nova Canvas model
Negative prompts to exclude unwanted elements
Configurable image dimensions and quality (standard/premium)
Deterministic output via seed control
Batch generation of 1–5 images per call
Input validation and error handling

Use cases of Amazon Bedrock MCP Server

Generate marketing visuals from textual descriptions
Create concept art or storyboard frames with precise composition control
Iterate on image designs by adjusting prompts, negative prompts, and seed values
Automate bulk image creation in CI/CD or content‑generation pipelines

よくある質問

What does the server do?

It generates images using Amazon Bedrock’s Nova Canvas model based on a text prompt and optional parameters like negative prompt, dimensions, quality, and seed.

What are the runtime requirements?

An active AWS account with Amazon Bedrock and Nova Canvas model access, properly configured AWS credentials, and Node.js 18 or later.

Where are generated images stored?

The README does not specify storage details; images are returned directly via the MCP tool response. No local or cloud persistence is mentioned.

Are there known performance limits?

Generation time increases with higher resolution (`width`, `height`), number of images, and quality level. Developers should account for potential timeout implications when using higher values.

How is authentication handled?

AWS credentials must be configured via environment variables, the AWS credentials file, or an IAM role (when deployed on AWS infrastructure). The server does not implement additional authentication.
