The MOSMCPStdioServer class was calling _setup_tools() which was not defined. Consolidated into MOSMCPServer which has the proper implementation.
- Create PostgresGraphDB class with full BaseGraphDB implementation - Add PostgresGraphDBConfig with connection pooling support - Register postgres backend in GraphStoreFactory - Update APIConfig with get_postgres_config method - Support GRAPH_DB_BACKEND env var with neo4j fallback Replaces Neo4j dependency with native PostgreSQL using: - JSONB for flexible node properties - pgvector for embedding similarity search - Standard SQL for graph traversal
Match krolik schema embedding dimension for compatibility
Add remove_oldest_memory and get_grouped_counts methods required by MemOS memory management functionality.
The merge/deduplicate logic was converting hit IDs to a set, losing the score-based ordering from vector search. Now keeps highest score per ID and returns results sorted by similarity score (descending). Fixes both _vector_recall and _fulltext_recall methods.
When embeddings aren't available, the reranker was defaulting to 0.5 scores, ignoring the relativity scores set during the recall phase. Now uses item.metadata.relativity from the recall stage when available. Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
- Add overlays/krolik/ with auth, rate-limit, admin API - Add Dockerfile.krolik for production builds - Add SYNC_UPSTREAM.md documentation - Keeps customizations separate from base MemOS for easy upstream sync

The previous version was for monkey-patching (krolik-server runtime patches) and doesn't belong in the fork. Restoring upstream version. The factory.py patch was: - Importing from memos.patches.universal_api (doesn't exist) - Designed for runtime patching, not fork integration Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Detailed workflow for making changes - CI/CD configuration documentation - Branch protection explained - Quick reference for common tasks Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add detailed logging to diagnose why search returns 0 results despite 105 activated memories: 1. searcher.py _retrieve_simple(): - Log embedder type and config before embed() call - Catch and log embedding generation failures - Log retrieve_from_mixed() results and exceptions 2. polardb.py search_by_embedding(): - Log input vector dimensions and search parameters - Log DB connection status and query execution - Log result counts at each stage - Catch and log any exceptions 3. recall.py _vector_recall(): - Log input embeddings count and memory scope - Log results from both search paths (A & B) - Log empty result warnings This will reveal whether: - VoyageAI embedder is failing silently - PolarDB search_by_embedding is catching exceptions - Query embedding is None (LLM parser issue) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Log parsed_goal.memories to understand why query_embedding is None in fast mode. This will reveal if TaskGoalParser is not returning memories, which causes the vector search to be skipped entirely. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Production log level is WARNING, so diagnostic logs need to use WARNING to be visible in docker logs. This will allow us to see: - Embedder configuration and failures - TaskGoalParser output (parsed_goal.memories) - Vector recall results - PolarDB search_by_embedding execution Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Logger.warning may be buffered or filtered. Using print() with flush=True ensures we see the output immediately in docker logs to confirm: 1. retrieve() is being called 2. parsed_goal.memories value Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add schedule==1.2.2 to docker/requirements.txt to fix scheduler initialization error. Module was present in requirements-full.txt but not in the base requirements used by Dockerfile. Fixes: ImportError: Missing required module - 'schedule' Fixes: mem_scheduler initialization failure (openai, graph_db components) This enables background memory activation in MemOS. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add print() and logger.warning() to track memory search results before they're returned from search_textual_memory(). This helps debug why PolarDB finds memories but API returns 0 results. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Apache AGE agtype string values retain surrounding double quotes when
converted via str(), causing ID mismatch in _vector_recall between
search_by_embedding results (quoted) and get_nodes results (unquoted).
This made all search results silently disappear.
Applied .strip('"') in 4 locations: search_by_embedding,
search_by_keywords_LIKE, search_by_keywords_TFIDF, search_by_fulltext.

…fix types - Remove ~1230 lines of dead/legacy code from polardb.py (5437→4206 lines): _old() methods, get_grouped_counts1, get_neighbors_by_tag_ccl, dead loops, debug prints, commented-out blocks, unused find_embedding - Merge _parse_node_new() into _parse_node() with quote-stripping - Extract _build_search_where_clauses_sql() shared by 4 search methods - Unify _build_filter_conditions cypher/sql into single dialect-parameterized method - Unify _build_user_name_and_kb_ids_conditions cypher/sql similarly - Extract shared utils to graph_dbs/utils.py (compose_node, prepare_node_metadata, etc.) - Fix method name typos: seach_by_keywords_* → search_by_keywords_* (with compat aliases) - Replace Neo4jGraphDB type hints with BaseGraphDB in 9 consumer files - Add 8 missing abstract methods to BaseGraphDB Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Components that are simply not configured (no env vars set) are not failures — stop spamming WARNING on every restart. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
get_default_config() was injecting act_mem into the config dict passed to MOSConfig, but MOSConfig has no act_mem field and inherits extra="forbid" from BaseConfig. This crashed memos-mcp on startup when ENABLE_ACTIVATION_MEMORY=true. The enable_activation_memory bool flag is sufficient for MOSConfig; act_mem config belongs in MemCube config (get_default_cube_config). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
get_default_cube_config() was hardcoding extractor_llm backend to "openai" for activation memory, but KVCacheMemory requires a local HuggingFace/vLLM model to extract internal attention KV tensors. This caused a ValidationError for any user calling get_default() with enable_activation_memory=True and a remote API key. Now checks activation_memory_backend kwarg (default: huggingface) and only creates act_mem config when a compatible local backend is specified. Logs a warning otherwise. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
get_default_cube_config only has remote API config (openai_config), which cannot be used for KV cache activation memory (needs local HuggingFace/vLLM model). Default to None instead of "huggingface" and require activation_memory_backend + activation_memory_llm_config kwargs to be explicitly provided for act_mem creation. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
get_default_cube_config() was hardcoded to neo4j graph DB backend.
Now reads graph_db_backend kwarg ("polardb"/"postgres" → PolarDB,
"neo4j" → Neo4j) and builds the appropriate config.
mcp_serve.py now maps GRAPH_DB_BACKEND, NEO4J_BACKEND, and
POLAR_DB_* env vars so the MCP server works with Postgres+AGE.

…MemTensor#1038 From MemTensor/MemOS PR MemTensor#1038 (Mozy403): - URL protection in all chunkers: URLs are replaced with placeholders before chunking and restored after, preventing mid-URL splits - Markdown header hierarchy auto-fix: detects when >90% of headers are H1 and auto-increments subsequent headers for better chunking - Language detection: strip URLs before Chinese character ratio calculation to prevent false language detection - file_content_parser: fix missing 3rd return value in error path Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Split the monolithic PolarDBGraphDB class (4206 lines, 66 methods) into a polardb/ package with 11 files using Python mixins: - connection.py: ConnectionMixin (pool, init, health checks) - schema.py: SchemaMixin (tables, indexes, extensions) - nodes.py: NodeMixin (node CRUD + agtype parsing) - edges.py: EdgeMixin (edge CRUD) - traversal.py: TraversalMixin (neighbors, subgraph, paths) - search.py: SearchMixin (keyword, fulltext, embedding search) - filters.py: FilterMixin (SQL/Cypher WHERE clause builders) - queries.py: QueryMixin (metadata queries, counts) - maintenance.py: MaintenanceMixin (import/export, clear, cleanup) - helpers.py: module-level utilities (escape_sql_string, generate_vector) Import path unchanged: from memos.graph_dbs.polardb import PolarDBGraphDB Also fixes pre-existing bug: self.execute_query() in count_nodes() did not exist — replaced with standard cursor pattern.
