rekal vs csharp-sdk
rekal: rekal provides long-term memory for LLMs via an MCP server. It stores memories in a local SQLite file and retrieves them using hybrid search (BM25 keywords + vector semantics + recency decay). It works with any MCP-capable agent like Claude Code, Codex CLI, and OpenCode.; csharp-sdk: The MCP C# SDK is the official C# SDK for the Model Context Protocol, designed to enable .NET applications, services, and libraries to implement and interact with MCP clients and servers. The Model Context Protocol (MCP) itself is an open protocol that standardizes how applications provide context to Large Language Models (LLMs), facilitating secure integration between LLMs and various data sources and tools.
