# Choose Secure MCP Transports

MCP servers need the right transport for local, web, and cloud deployments. This skill compares stdio, SSE, HTTP streaming, and custom options.

## Capabilities

- Compares stdio, SSE, HTTP streaming, and custom MCP transports.
- Explains when each transport fits local, cloud, and web deployments.
- Provides Rust examples for server setup, handlers, tests, and deployment.
- Covers TLS, authentication, rate limiting, logging, and metrics guidance.
- Helps design custom transports such as WebSocket-based transport layers.

## Use Cases

- Select a transport for a new MCP server: Compare local and remote deployment needs, then choose stdio, SSE, HTTP streaming, or a custom transport.
- Prepare a remote MCP service: Plan HTTP or SSE hosting with authentication, TLS, rate limiting, and monitoring considerations.
- Review transport design choices: Check whether an existing MCP server uses a transport that matches its clients, scale, and security needs.

## Prompt Templates

### Pick a transport

```
Help me choose an MCP transport for my server. My clients are local desktop users, and I need simple setup.
```

### Compare deployment options

```
Compare stdio, SSE, and HTTP streaming for an MCP server behind a load balancer. Include security tradeoffs.
```

### Review a transport implementation

```
Review my MCP transport design for production. Focus on authentication, TLS, rate limiting, logging, and failure handling.
```

### Design a custom transport

```
Design a custom MCP transport for constrained devices. Explain message framing, backpressure, retries, and observability.
```

## Limitations

- It is guidance only and does not install or run MCP servers.
- Examples need project-specific validation before production use.
- It focuses on Rust MCP patterns more than other languages.
- It does not replace a full security review for remote deployments.

## Best Practices

- Start with the narrowest transport that supports your clients and deployment model.
- Use TLS, authentication, and rate limiting for every remote MCP transport.
- Test transport behavior separately from tool business logic.

## Anti Patterns

- Do not expose a local development MCP server on all interfaces by default.
- Do not use open CORS settings for authenticated remote MCP endpoints.
- Do not log complete MCP requests when they may contain sensitive data.

## Security Audit

- Audited at: 2026-07-05T14:53:39.658\+00:00
- Summary: Most static findings are false positives from Markdown code fences and Rust examples, including tokio::spawn and placeholder TLS filenames. The confirmed risks are all-interface listener examples, permissive CORS guidance, and full request logging guidance.
