context-harness vs state-memory-mcp

context-harness: Context Harness is a local-first framework designed for ingesting and retrieving external knowledge into an AI tool's context. It supports various data sources like files, Git repositories, and S3 buckets, storing them in a local SQLite database for efficient keyword and semantic search.; state-memory-mcp: @putervision/state-memory-mcp is a zero-infrastructure, deterministic Model Context Protocol (MCP) server designed to provide AI coding assistants with a structured, persistent SQLite graph for tracking workflow state. It offers efficient context management, reduces latency by offloading to a local database, and supports multi-agent collaboration with a shared blackboard.
