# mcp-hmr
[](https://pypi.org/project/mcp-hmr/)
[](https://pepy.tech/projects/mcp-hmr)
Provides [Hot Module Reloading](https://pyth-on-line.promplate.dev/hmr) for MCP/FastMCP servers.
It acts as **a drop-in replacement for `mcp run path:app` or `fastmcp run path:app`.** Both [FastMCP v2](https://github.com/jlowin/fastmcp) and the [official python SDK](https://github.com/modelcontextprotocol/python-sdk) are supported.
## Usage
If your server instance is named `app` in `./path/to/main.py`, you can run:
```sh
mcp-hmr ./path/to/main.py:app
```
Which will be equivalent to `fastmcp run ./path/to/main.py:app` but with [HMR](https://github.com/promplate/hmr) enabled.
Or using module import format:
```sh
mcp-hmr main:app
```
Now, whenever you save changes to your source code, the server will automatically reload without dropping the connection to the client.
