What is S3 YAML MCP Server?

A Model Context Protocol (MCP) server that connects to AWS S3 to provide access to YAML files containing Swagger/OpenAPI documentation. Designed for seamless integration with VS Code and GitHub Copilot, it enables AI assistants to discover, search, and read API specifications stored in S3.

How to use S3 YAML MCP Server?

Install via the recommended one-line script, Go install, binary download, or Docker. Set the required environment variable S3_BUCKET (optionally S3_REGION, S3_ENDPOINT, etc.) and create a .vscode/mcp.json file to register the server in VS Code. After installation, open VS Code and use GitHub Copilot Chat with commands like @s3YamlDocs list all YAML files to interact with your S3-hosted specifications.

常见问题

What are the prerequisites?

AWS credentials configured (AWS CLI, IAM roles, or environment variables), an S3 bucket containing YAML files, and VS Code with the GitHub Copilot extension.

How do I install S3 YAML MCP Server?

Four methods: one-line install (`curl … | bash`), Go install (`go install …`), downloading a binary from the releases page, or Docker (`docker pull ghcr.io/ander-castiblanco-stori/s3-mcp-server:latest`).

What environment variables must be configured?

`S3_BUCKET` is required. Optional variables include `S3_REGION` (default `us-east-1`), `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, `S3_ENDPOINT` (for S3-compatible services), and `LOG_LEVEL`.

Which AWS S3 permissions are needed?

The credentials require `s3:GetObject`, `s3:ListBucket`, `s3:HeadBucket`, and `s3:HeadObject` on the bucket and its objects.

Can I use an S3-compatible service instead of AWS S3?

Yes. Set the `S3_ENDPOINT` environment variable to point to your S3-compatible service (e.g., MinIO, DigitalOcean Spaces).
