### Description (declared)

# durable-mcp

This repository contains demonstrations of durable MCP - a simple one and a more complex one:
- the simple one implements an MCP server, starting with one shown in the [MCP Server Developers Quickstart](https://modelcontextprotocol.io/quickstart/server). We add Temporal to make the server durable.
- the more complex one does quite a bit more - it:
  - includes an MCP client 
  - ... and a very simple application that uses this client
  - includes a much more sophisticated MCP server that includes elicitation and sampling
  - ... and in a separate branch, a demonstration of the remote MCP transport protocol
  - We use Temporal to make the MCP server durable.

I go more into each of the two demos below.

The main branch has an implementation that extends the initial sample with durability, using Temporal. The original implementation can be found in the nondurable branch. Each branch has its own 
version of this README, guiding you through the demonstration.

# Demo 1 - simple, but durable MCP server

In this demo we take the very simple weather MCP server from the official [MCP Server Developers Quickstart](https://modelcontextprotocol.io/quickstart/server) and we make it durable by wrapping the downstream calls to the National Weather Service (NWS) APIs in activities and orchestrate them in a workflow. I literally changed (almost) none of the original code, except to put pieces in different files with the appropriate Temporal annotations added.

The following diagram shows the business logic for the GetForecast tool:

The one thing that I did change is that I had to get rid of some of the error handling code from the original - because the exception was getting swallowed, Temporal never saw the error and couldn't compensate for it. Hmm, error handling in code might just be a bug.

I intentionally used Claude Desktop as the MCP client because we are seeing many use …
