Dynoxide MCP Server

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

People connecting database tools to 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.
