| MEM0_PORT | No | Port for SSE/HTTP transports. | 8081 |
| MEM0_LLM_URL | No | Ollama base URL for the main LLM. Cascades: MEM0_LLM_URL → MEM0_OLLAMA_URL → http://localhost:11434. Only used when MEM0_LLM_PROVIDER=ollama. | |
| MEM0_USER_ID | No | Default user ID for memory scoping. | user |
| MEM0_PROVIDER | No | Top-level provider (`anthropic` or `ollama`). Cascades to MEM0_LLM_PROVIDER and MEM0_GRAPH_LLM_PROVIDER when those are not set. Does not affect MEM0_EMBED_PROVIDER. | anthropic |
| GOOGLE_API_KEY | No | Google API key (required for `gemini`/`gemini_split` graph providers). | |
| MEM0_EMBED_URL | No | Ollama URL for embeddings. Cascades: MEM0_EMBED_URL → MEM0_OLLAMA_URL → http://localhost:11434. | |
| MEM0_LLM_MODEL | No | Model for the selected LLM provider. Defaults to `claude-opus-4-6` for Anthropic, `qwen3:14b` for Ollama. | |
| MEM0_LOG_LEVEL | No | Logging level (`DEBUG`, `INFO`, `WARNING`, `ERROR`). | INFO |
| MEM0_NEO4J_URL | No | Neo4j Bolt endpoint. | bolt://127.0.0.1:7687 |

| MEM0_COLLECTION | No | Qdrant collection name. | mem0_mcp_selfhosted |
| MEM0_EMBED_DIMS | No | Embedding vector dimensions. | 1024 |
| MEM0_NEO4J_USER | No | Neo4j username. | neo4j |
| MEM0_OLLAMA_URL | No | Shared Ollama base URL. Cascades to MEM0_LLM_URL, MEM0_EMBED_URL, and MEM0_GRAPH_LLM_URL when those are not set. | http://localhost:11434 |

| MEM0_EMBED_MODEL | No | Embedding model name. | bge-m3 |
| MEM0_OAT_HEADERS | No | OAT identity headers: `auto` or `none`. | auto |
| ANTHROPIC_API_KEY | No | Standard Anthropic API key (priority 3 in the token fallback chain). Only useful for non-Claude-Code deployments (Docker, CI, standalone). | |
| MEM0_ENABLE_GRAPH | No | Enable graph memory (entity extraction to Neo4j). | false |
| MEM0_LLM_PROVIDER | No | Main LLM provider: `anthropic` or `ollama`. Inherits from MEM0_PROVIDER when not set. | |
| MEM0_OLLAMA_THINK | No | Set to `true` to re-enable qwen3 thinking mode (disabled by default to prevent ` thinking` + `format:"json"` collision). | false |
| MEM0_GRAPH_LLM_URL | No | Ollama base URL for graph LLM. Cascades: MEM0_GRAPH_LLM_URL → MEM0_LLM_URL → MEM0_OLLAMA_URL → http://localhost:11434. | |
| MEM0_EMBED_PROVIDER | No | Embedding provider (`ollama` or `openai`). | ollama |
| MEM0_LLM_MAX_TOKENS | No | Max tokens for LLM responses (Anthropic only). | 16384 |
| MEM0_NEO4J_DATABASE | No | Neo4j database name (multi-database setups). | |

| MEM0_QDRANT_API_KEY | No | Qdrant API key (for Qdrant Cloud). | |
| MEM0_QDRANT_ON_DISK | No | Store vectors on disk (reduces RAM, slower search). | false |
| MEM0_QDRANT_TIMEOUT | No | Qdrant REST API timeout in seconds (e.g., `30`). Only set if you hit ReadTimeout during collection operations. | |
| MEM0_ANTHROPIC_TOKEN | No | Anthropic OAT or API token (priority 1 in the token fallback chain). Use to override the automatically-read Claude Code OAT token. | |
| MEM0_GRAPH_LLM_MODEL | No | Graph model. Inherits MEM0_LLM_MODEL for anthropic/ollama; defaults to `gemini-2.5-flash-lite` for gemini/gemini_split. | |
| MEM0_GRAPH_THRESHOLD | No | Embedding similarity threshold for node matching. | 0.7 |
| MEM0_HISTORY_DB_PATH | No | SQLite path for memory change history. | |
| MEM0_NEO4J_BASE_LABEL | No | Custom Neo4j base label for node type grouping. | |
| MEM0_OLLAMA_KEEP_ALIVE | No | How long Ollama keeps the model in VRAM between calls (e.g., `1h`, `5m`). Prevents model unload during multi-call graph pipelines. | 30m |
| MEM0_GRAPH_LLM_PROVIDER | No | Graph LLM provider (`anthropic`, `anthropic_oat`, `ollama`, `gemini`, `gemini_split`). Inherits from MEM0_PROVIDER when not set. | |
