Melchizedek
Gives Claude searchable memory across all your coding sessions by indexing conversation history into a local SQLite database. Exposes 16 MCP tools including m9k_search for hybrid BM25 and vector search, m9k_file_history to find past work on specific files, and m9k_errors to surface previous solutions. Runs entirely offline with automatic indexing via session hooks. The search pipeline gracefully degrades from full semantic search with reranking down to pure keyword search depending on what's installed. Useful when you're debugging something you solved months ago in a different project, or when Claude needs context about architectural decisions from past sessions. Current project results get boosted automatically.

Melchizedek
Persistent memory for Claude Code. Automatically indexes every conversation and provides production-grade hybrid search (BM25 + vectors + reranker) via MCP tools. 100% local, zero config, zero API keys, zero invoice.
Why Melchizedek?
Claude Code forgets everything between sessions - and knows nothing about your other projects. Melchizedek fixes both.
