durable-mcp 0.1.2

Durable Model Context Protocol (MCP) helpers for building resumable MCP servers on top of Reboot durable workflows.

Reboot Durable MCP

A framework for building durable MCP servers.

• Takes advantage of the protocols ability to resume after disconnection.

• Allows for the server itself to be restarted(!) and any existing requests to be retried safely thanks to Reboot workflows.
