Dynoxide MCP Server

A DynamoDB emulator in Rust, backed by SQLite. Runs as an HTTP server or an MCP server for coding agents, embeds into Rust and iOS applications as a library, and compiles to WebAssembly for the browser. It runs locally over stdio via the published package.

People who work with aws, database and dynamodb and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Rust.

01 · Install Dynoxide

Claude Code

claude mcp add nubo-db-dynoxide -- npx -y dynoxide

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "nubo-db-dynoxide": {
      "command": "npx",
      "args": [
        "-y",
        "dynoxide"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · container (OCI image) - can be sandboxed away from your filesystem

license Apache-2.0 - declared in the repository

npm package dynoxide - unscoped; check the name against the project README before installing

registry namespace io.github.nubo-db is GitHub-verified and matches the repo owner

03 · What Dynoxide can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

Limitations (from the README)

Dynoxide is built for local development, testing, and CI, not as a production DynamoDB replacement, so two classes of thing are missing on purpose. Cloud-only operations with no local equivalent aren't implemented: backups and point-in-time restore, global tables, Kinesis streaming, resource policies, and capacity management. Call one and you get an UnknownOperationException.
