What is mcp-transport-prototype?
mcp-transport-prototype is a prototype implementation for understanding how to build a custom MCP server accessible over both stdio and SSE transports. It explores the differences between Server-Sent Events (SSE) and standard input/output (stdio) for MCP communication.
How to use mcp-transport-prototype?
Run the server with uv run main.py in one terminal, and the client with uv run mcp_client.py in another to test the SSE transport. No further configuration details are provided.
Key features of mcp-transport-prototype
- Implements MCP server over SSE and stdio transports
- Demonstrates one-way real-time streaming via SSE over HTTP
- Shows traditional process communication via stdio
- Includes a sample client script to test SSE mode
Use cases of mcp-transport-prototype
- Understanding how to build custom MCP servers with different transports
- Testing SSE for web dashboards or browser-based apps needing live updates
- Using stdio for command-line tools or LLM agents launching MCP as subprocess
