# Local vs Remote Hosted MCP Servers: Architecture, Latency, and Deployment

> Comparing local stdio MCP servers for desktop agents against remote streamable HTTP MCP servers for scalable multi-tenant SaaS platforms.

Should you run your MCP servers locally via stdio or host them remotely over streamable HTTP? Here is the complete architectural guide to latency, security, and deployment tradeoffs.

## Understanding the two MCP transport paradigms

Model Context Protocol supports two primary communication transports: Standard Input/Output (stdio) for local processes, and Streamable HTTP for remote network services.

Choosing the right transport depends on whether you are building a personal developer assistant (Claude Desktop / Cursor) or a centralized enterprise SaaS with hundreds of autonomous agents.

## Detailed Tradeoff Matrix

| Metric | Local Stdio MCP | Remote Hosted HTTP MCP |
| --- | --- | --- |
| Primary Use Case | Local CLI, Claude Desktop, Cursor | Multi-agent SaaS, Web Apps, Serverless |
| Round-Trip Latency | < 2ms (inter-process pipe) | 20ms–80ms (network dependent) |
| Security Perimeter | Local machine file & env isolation | OAuth 2.0 / mTLS / API Gateways |
| Deployment Complexity | Zero infra (spawned on demand) | Kubernetes, Cloudflare, or AWS Lambda |
| Multi-Tenancy | Single user per process | Shared multi-tenant isolation with rate limiting |

## When to choose Remote Streamable HTTP

If multiple AI agents across your company need access to shared email infrastructure, centralized logging, and organizational allowlists, deploy a centralized remote MCP server behind an API Gateway.
