Prerrequisitos
Cuenta activa de AWS con acceso al modelo Amazon Bedrock y Nova Canvas
Credenciales de AWS configuradas correctamente con los permisos necesarios
Node.js versión 18 o posterior
Instalación
Configuración de credenciales de AWS
El servidor requiere credenciales de AWS con los permisos adecuados de Amazon Bedrock. Configúrelas mediante uno de los siguientes métodos:
Variables de entorno:
export AWS_ACCESS_KEY_ID=your_access_key export AWS_SECRET_ACCESS_KEY=your_secret_key export AWS_REGION=us-east-1 # or your preferred regionArchivo de credenciales de AWS (
~/.aws/credentials):[the_profile_name] aws_access_key_id = your_access_key aws_secret_access_key = your_secret_keyVariable de entorno para el perfil activo:
export AWS_PROFILE=the_profile_nameRol de IAM (cuando se implementa en la infraestructura de AWS)

generar_imagen
Crea imágenes a partir de descripciones de texto utilizando el modelo Nova Canvas de Amazon Bedrock.
Parámetros
prompt(obligatoria): Texto descriptivo de la imagen deseada (1-1024 caracteres)negativePrompt(opcional): Elementos a excluir de la imagen (1-1024 caracteres)width(opcional): Ancho de la imagen en píxeles (predeterminado: 1024)height(opcional): altura de la imagen en píxeles (predeterminado: 1024)quality(opcional): Nivel de calidad de imagen: "estándar" o "premium" (predeterminado: "estándar")cfg_scale(opcional): Intensidad de adherencia rápida (1,1-10, valor predeterminado: 6,5)seed(opcional): Semilla de generación para reproducibilidad (0-858993459, predeterminado: 12)numberOfImages(opcional): tamaño del lote para la generación (1-5, predeterminado: 1)
Ejemplo de implementación
const result = await callTool('generate_image', {
prompt: "A serene mountain landscape at sunset",
negativePrompt: "people, buildings, vehicles",
quality: "premium",
cfg_scale: 8,
numberOfImages: 2
});Pautas de indicaciones
Para obtener resultados óptimos, evite usar frases negativas ("no", "no", "sin") en la solicitud principal. En su lugar, mueva estos elementos al parámetro negativePrompt ". Por ejemplo, en lugar de usar "un paisaje sin edificios" en la solicitud, use "edificios" en " negativePrompt ".
Para obtener instrucciones de uso detalladas, consulte la documentación de Nova Canvas .
Desarrollo
Para configurar y ejecutar el servidor en un entorno local:
git clone https://github.com/zxkane/mcp-server-amazon-bedrock.git
cd mcp-server-amazon-bedrock
npm install
npm run buildConsideraciones de rendimiento
El tiempo de generación se ve afectado por la resolución ( width y height ), numberOfImages y la configuración quality . Al usar valores más altos, tenga en cuenta las posibles implicaciones de tiempo de espera en su implementación.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions the return format (Base64-encoded string) but lacks critical details such as rate limits, authentication requirements, error handling, or whether this is a read/write operation. For a complex image generation tool, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is concise and front-loaded, consisting of two clear sentences. However, it could be slightly more efficient by combining ideas, but it avoids unnecessary verbosity.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the complexity of an image generation tool with 8 parameters and no output schema or annotations, the description is incomplete. It covers the basic purpose and return format but misses behavioral context, usage guidelines, and output details, leaving significant gaps for an AI agent.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 8 parameters. The description adds no parameter-specific information beyond what's in the schema, resulting in a baseline score of 3.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the tool's purpose: 'Generate image(s) using Amazon Nova Canvas model.' It specifies the verb ('generate') and resource ('image(s)'), and identifies the specific model. However, without sibling tools, we cannot assess differentiation, so it cannot achieve a perfect 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives, prerequisites, or typical use cases. It simply states what the tool does without context for selection.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 1 tool
With only one tool, there is no possibility of confusion or overlap between tools. The tool 'generate_image' has a clear and distinct purpose that cannot be mistaken for any other tool in the set.
The single tool name 'generate_image' follows a verb_noun pattern, and with only one tool, consistency is inherently perfect. There are no other tools to compare against, so no inconsistencies can arise.
A single tool is too few for a server named 'Amazon Bedrock MCP Server', which suggests a broader scope related to Amazon Bedrock services. This minimal toolset feels thin and incomplete for the implied domain, limiting functionality to just image generation.
The tool surface is severely incomplete for the server's purpose. Amazon Bedrock includes multiple models and capabilities beyond image generation, such as text generation, embeddings, and model management. The single tool fails to cover these core aspects, leaving significant gaps that will cause agent failures.
