rekal vs org-mcp-server

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.; org-mcp-server: org-mcp-server is a Model Context Protocol (MCP) server for org-mode knowledge management. It provides search, content access, and note linking capabilities through the MCP protocol. The project includes a CLI tool for direct interaction and supports configuration via TOML file, environment variables, and command-line flags.
