ogham-mcp vs overmind

ogham-mcp: Ogham MCP is a persistent, searchable shared memory system for AI coding agents that works across different clients and sessions. It stores memories as vector embeddings in PostgreSQL, enabling hybrid search combining semantic and full-text retrieval with high accuracy. Ogham supports multiple embedding providers, knowledge graph traversal, wiki compilation, and automatic memory management features like scoring, condensing, and novelty detection.; overmind: Overmind is the first open-source event-driven AI agent cognitive architecture that serves as an external brain for Claude Code. It provides permanent memory, multi-window fleet collaboration, and pre-answer self-checking to eliminate hallucinations and rework.
