AWS
Amazon AWS Lab’s official MCP servers that enable developers to leverage the full power of AWS within their AI workflows.
How to Use It
1. Install Prerequisites:
- Install
uvfrom Astral: Follow the installation instructions on the Astral website. - Install Python using
uv: Runuv python install 3.10.
2. Configure AWS Credentials:
- Set up your AWS credentials with access to the required services.
3. Add MCP Servers to Your Configuration:
- Create or edit your MCP client configuration file (e.g.,
~/.aws/amazonq/mcp.jsonfor Amazon Q CLI). - Add the desired AWS MCP Servers to the
mcpServersobject. For example:
{
"mcpServers": {
"awslabs.core-mcp-server": {
"command": "uvx",
"args": ["awslabs.core-mcp-server@latest"],
"env": {
"FASTMCP_LOG_LEVEL": "ERROR"
}
},
"awslabs.nova-canvas-mcp-server": {
"command": "uvx",
"args": ["awslabs.nova-canvas-mcp-server@latest"],
"env": {
"AWS_PROFILE": "your-aws-profile",
"AWS_REGION": "us-east-1",
"FASTMCP_LOG_LEVEL": "ERROR"
}
}
}
}4. Use MCP Servers in Your AI Workflow:
- When using an AI assistant that supports MCP (e.g., Amazon Q, Cline, Cursor), prompt it to use specific AWS MCP Servers for tasks.
- For example: “Using the Terraform MCP Server, create an infrastructure plan for a scalable web application on AWS.”
5. Manage MCP Server Versions:
- To use the latest version, keep the
@latestsuffix in theargsarray. - To minimize initial load times, remove
@latestand manage youruvcache manually: - Clean the cache:
uv cache clean <tool> - Update a specific tool:
uvx <tool>@latest
FAQs
Q: How do AWS MCP Servers improve the accuracy of AI-generated outputs?
A: AWS MCP Servers provide context-specific information, up-to-date documentation, and direct access to AWS services. This enables AI models to generate more accurate and relevant responses for AWS-related tasks, reducing hallucinations and outdated information.
Q: Can I use AWS MCP Servers with any AI assistant?
A: AWS MCP Servers are designed to work with AI assistants that support the Model Context Protocol (MCP). Currently, they are compatible with tools like Amazon Q, Cline, Cursor, and Windsurf.
Q: How do I ensure the security of my AWS resources when using MCP Servers?
A: AWS MCP Servers use your configured AWS credentials to access resources. Ensure you follow AWS security best practices, such as using IAM roles with least privilege principles, and regularly rotate your credentials. Additionally, review and approve any actions suggested by the AI assistant before execution.

FAQs
Q: What exactly is the Model Context Protocol (MCP)?
A: MCP is an open standard, like a common language, that lets AI applications (clients) and external data sources or tools (servers) talk to each other. It helps AI models get the context (data, instructions, tools) they need from outside systems to give more accurate and relevant responses. Think of it as a universal adapter for AI connections.
Q: How is MCP different from OpenAI's function calling or plugins?
A: While OpenAI's tools allow models to use specific external functions, MCP is a broader, open standard. It covers not just tool use, but also providing structured data (Resources) and instruction templates (Prompts) as context. Being an open standard means it's not tied to one company's models or platform. OpenAI has even started adopting MCP in its Agents SDK.
Q: Can I use MCP with frameworks like LangChain?
A: Yes, MCP is designed to complement frameworks like LangChain or LlamaIndex. Instead of relying solely on custom connectors within these frameworks, you can use MCP as a standardized bridge to connect to various tools and data sources. There's potential for interoperability, like converting MCP tools into LangChain tools.
Q: Why was MCP created? What problem does it solve?
A: It was created because large language models often lack real-time information and connecting them to external data/tools required custom, complex integrations for each pair. MCP solves this by providing a standard way to connect, reducing development time, complexity, and cost, and enabling better interoperability between different AI models and tools.
Q: Is MCP secure? What are the main risks?
A: Security is a major consideration. While MCP includes principles like user consent and control, risks exist. These include potential server compromises leading to token theft, indirect prompt injection attacks, excessive permissions, context data leakage, session hijacking, and vulnerabilities in server implementations. Implementing robust security measures like OAuth 2.1, TLS, strict permissions, and monitoring is crucial.
Q: Who is behind MCP?
A: MCP was initially developed and open-sourced by Anthropic. However, it's an open standard with active contributions from the community, including companies like Microsoft and VMware Tanzu who maintain official SDKs.
