Mnemos

About

Mnemos is a self-hosted, multi-context memory server designed for developers to transform their documentation piles into a powerful, private knowledge system. It enables the organization of documents into isolated collections, ensuring context remains project-specific, and utilizes deterministic re-ingestion to efficiently update content. Powered by local vector search via Ollama and pgvector, Mnemos guarantees 100% privacy with zero vendor lock-in, making your context searchable and accessible entirely offline and via the Model Context Protocol (MCP).

• Deterministic Re-ingestion with SHA-256 hashing for idempotency
• Stable Local Embeddings optimized for Ollama
• 1 GitHub stars
• Multi-context Collections for isolating knowledge by project
• Recursive Site Crawling for ingesting entire documentation sites
• 100% private with fully offline operation and zero external calls

Use Cases

• Building project-specific knowledge bases from documentation (e.g., React, Rust docs)
• Providing external, context-rich information to AI agents via the Model Context Protocol
