What is Hot Module Reload (HMR) and why would I use it in Python?

HMR allows your Python code to update and reload without restarting your application or MCP server, speeding up development iteration. Combined with reactive programming, it enables live-updating data flows and state management.

How do I connect to the HMR MCP server?

The server is hosted at https://promplate.github.io/pyth-on-line/hmr/mcp and uses HTTP transport. Configure your MCP client to point to this endpoint to access HMR tools and capabilities.

What MCP tools are available for managing module reloads?

The registry indicates MCP tools are provided, but specific tool names and schemas are not detailed in the available metadata. Consult the server's documentation or introspect the MCP endpoint to discover available tools.

Does this HMR server support reactive programming frameworks?

Yes, the server is designed with reactive programming patterns in mind. It integrates HMR with reactive paradigms to enable live updates to reactive data streams and state.

Is there a local alternative to the hosted HMR endpoint?

The registry shows only the hosted HTTP endpoint. For local deployment or self-hosting options, check the project repository at io.github.promplate/hmr for installation and configuration instructions.
