mcp_flow_runtime 0.2.1

Runtime for executing hardware control flows and IoT orchestration using MCP Flow DSL with process scheduling and state management.

Changelog

0.2.1 - 2026-05-23 - mcp_bundle 0.4.0 cascade

Changed (cascade)

• mcp_bundle caret bumped from ^0.3.0 to ^0.4.0. mcp_flow_runtime does not touch UiSection.pages directly, so this release is a caret-only cascade. Consumers should bump to ^0.2.1.

0.2.0 - 2026-04-28 - Platform Providers, Compact Runtime, Bundle Integration

Added

• Real-platform HAL providers — Linux GPIO / I2C / SPI, Windows GPIO, MQTT, alongside the existing mock factory.
• Compact flow subsystem — compiler, loader, executor, and types for embedded / restart-friendly deployment.
• Process resilience — watchdog, circuit breaker, backup manager.
• Channels subsystem and inter-process messaging primitives.
• Expression engine module.
• Encrypted state store (alongside in-memory and persistent stores).
• Bundle integration — load flows from MCP bundles.
• Logging, monitoring, network, resources, security, and services modules.
• MCP integration — flows exposed as MCP tools/resources.
• Examples — multiple-triggers and trigger-debounce flows.

Changed

• Runtime / scheduler / process executor / action executor refactored around the new compact runtime and HAL.
• New dependency: mcp_bundle ^0.3.0.
• License changed from Apache-2.0 to MIT.
