mcp-memory-service v11.6 — Now Available

Memory for AI Agents

Persistent memory for AI agents — REST API, MCP, OAuth, CLI, dashboard. Semantic search, knowledge graph, automatic consolidation. One self-hosted service, every transport.

Try the Live Demo Codeberg PyPI Package

Interactive 3D knowledge graph — every memory a glowing node, every relationship a curved edge.

What's New in v11.6

MINOR release: the re-embedding migration no longer drops your knowledge graph, locale-aware NER/NLI ship as YAML plugins, and both Docker images now carry the maintenance and migration scripts. ~2,698 tests.

🔗

Migration Preserves the Graph

migrate_sqlite_vec_embeddings.py rebuilt the database from memories alone, silently dropping memory_graph edges and derived beliefs on every re-embed. Both now survive the swap, keyed on their content hashes. (#189, reported by @tecnobrat)

🌐

Locale-Aware NER + NLI

Entity extraction and contradiction detection now load per-locale YAML pattern files instead of hardcoded regex. Ships with en and pt_BR; adding a language is two YAML files and zero Python code. (#54)

📦

Docker Ships the Toolbox

scripts/maintenance and scripts/migration are now in both published images, so re-embedding or cleanup no longer needs a docker cp into a running container first. (#188)
