Install (will use default SQLite database) pipx install memorygraphMCP # 1b. Optionally, you can specify a backend pipx install "memorygraphMCP[falkordblite]" # 2. Add to Claude Code (see docs/quickstart/ for other coding agents) claude mcp add --scope user memorygraph -- memorygraph # 3. Restart Claude Code (exit and run 'claude' again) ``` **Verify it works:** ```bash claude mcp list # Should show memorygraph with "Connected" ``` Then in your coding agent you can ask it to remember important items: *"Remember this for later: Use pytest for Python testing"*  > **Other MCP clients?** See [Supported Clients](#supported-mcp-clients) below. > > **Need pipx?** `pip install --user pipx && pipx ensurepath` > > **Command not found?** Run `pipx ensurepath` and restart your terminal. **Important:** MemoryGraph provides memory tools, but your coding agent won't use them automatically. You need to prompt or configure it to store memories. See [Memory Best Practices](#memory-best-practices) below. **Quick setup:** Add this to your `~/.claude/CLAUDE.md` or `AGENTS.md` to enable automatic memory storage: ```markdown ## Memory Protocol ### REQUIRED: Before Starting Work You MUST use `recall_memories` before any task. Query by project, tech, or task type. ### REQUIRED: Automatic Storage Triggers Store memories on ANY of: - **Git commit** → what was fixed/added - **Bug fix** → problem + solution - **Version release** → summarize changes - **Architecture decision** → choice + rationale - **Pattern discovered** → reusable approach ### Timing Mode (default: on-commit) `memory_mode: immediate | on-commit | session-end` ### Memory Fields - **Type**: solution | problem | code_pattern | fix | error | workflow - **Title**: Specific, searchable (not generic) - **Content**: Accomplishment, decisions, patterns - **Tags**: project, tech, category (REQUIRED) - **Importance**: 0.8+ critical, 0.5-0.7 standard, 0.3-0.4 minor - **Relationships**: Link related memories when they exist Do NOT wait to be asked. Memory storage is automatic. ``` See [CLAUDE.md Examples](docs/examples/CLAUDE_MD_EXAMPLES.md) for more configuration templates. ## Supported MCP Clients MemoryGraph works with any MCP-compliant AI coding tool: | Client | Type | Quick Start | |--------|------|-------------| | **Claude Code** | CLI/IDE | [Setup Guide](docs/CLAUDE_CODE_SETUP.md) | | **Claude Desktop** | Desktop App | [Setup Guide](docs/quickstart/CLAUDE_DESKTOP.md) | | **ChatGPT Desktop** | Desktop App | [Setup Guide](docs/quickstart/CHATGPT_DESKTOP.md) | | **Cursor AI** | IDE | [Setup Guide](docs/quickstart/CURSOR_SETUP.md) | | **Windsurf** | IDE | [Setup Guide](docs/quickstart/WINDSURF_SETUP.md) | | **VS Code + Copilot** | IDE (1.102+) | [Setup Guide](docs/quickstart/VSCODE_COPILOT_SETUP.md) | | **Continue.dev** | VS Code/JetBrains | [Setup Guide](docs/quickstart/CONTINUE_SETUP.md) | | **Cline** | VS Code | [Setup Guide](docs/quickstart/CLINE_SETUP.md) | | **Gemini CLI** | CLI | [Setup Guide](docs/quickstart/GEMINI_CLI_SETUP.md) | See [CONFIGURATION.md](docs/CONFIGURATION.md) for detailed compatibility info. --- ## Why MemoryGraph? ### Graph Relationships Make the Difference Research shows that naive vector search degrades on long-horizon and temporal tasks. Benchmarks such as Deep Memory Retrieval (DMR) and LongMemEval were introduced precisely because graph-based systems excel at temporal queries ("what did the user decide last week"), cross-session reasoning, and multi-hop questions requiring explicit relational paths. Graph memory captures entities, relationships, and temporal markers that traditional vector stores miss. For example: `Alice COMPLETED authentication_service`, `Bob BLOCKED_BY schema_conflicts` with timeline information about when events occurred. **Flat storage** (CLAUDE.md, vector stores): ``` Memory 1: "Fixed timeout by adding retry logic" Memory 2: "Retry logic caused memory leak" Memory 3: "Fixed memory leak with connection pooling" ``` No connection between these - search finds them separately. Best for static rules and prime directives. **Graph storage** (MemoryGraph): ``` [timeout_fix] --CAUSES--> [memory_leak] --SOLVED_BY--> [connection_pooling] | | +------------------SUPERSEDED_BY------------------------+ ``` Query: "What happened with retry logic?" → Returns the full causal chain. ### When to Use What | Use CLAUDE.md For | Use MemoryGraph For | |-------------------|---------------------| | "Always use 2-space indentation" | "Last time we used 4-space, it broke the linter" | | "Run tests before committing" | "The auth tests failed because of X, fixed by Y" | | Static rules, prime directives | Dynamic learnings with relationships | ### Relationship Types MemoryGraph tracks 7 categories of relationships: - **Causal**: CAUSES, TRIGGERS, LEADS_TO, PREVENTS - **Solution**: SOLVES, ADDRESSES, ALTERNATIVE_TO, IMPROVES - **Context**: OCCURS_IN, APPLIES_TO, WORKS_WITH, REQUIRES - **Learning**: BUILDS_ON, CONTRADICTS, CONFIRMS - **Similarity**: SIMILAR_TO, VARIANT_OF, RELATED_TO - **Workflow**: FOLLOWS, DEPENDS_ON, ENABLES, BLOCKS - **Quality**: EFFECTIVE_FOR, PREFERRED_OVER, DEPRECATED_BY --- ## Choose Your Mode | Feature | Core (Default) | Extended | |---------|----------------|----------| | Memory Storage | 9 tools | 12 tools | | Relationships | Yes | Yes | | Session Briefings | Yes | Yes | | Database Stats | - | Yes | | Complex Queries | - | Yes | | Contextual Search | - | Yes | | Backend | SQLite | SQLite | | Setup Time | 30 sec | 30 sec | ```bash memorygraph # Core (default, 9 tools) memorygraph --profile extended # Extended (12 tools) ``` ### Core Mode (Default) Provides all essential tools for daily use. Store memories, create relationships, search with fuzzy matching, and get session briefings. **This is all most users need.** ### When to Use Extended Mode Switch to extended mode when you need: - **Database statistics** (`get_memory_statistics`) - See total memories, breakdown by type, average importance scores, and graph metrics. Useful for understanding how your knowledge base is growing. - **Complex relationship queries** (`search_relationships_by_context`) - Search relationships by structured context fields like scope, conditions, and evidence. Example: "Find all partial implementations" or "Show relationships with experimental evidence." **Common extended mode scenarios:** - Auditing your memory graph before a major refactor - Analyzing patterns across hundreds of memories - Finding all conditionally-applied solutions - Generating reports on project knowledge coverage ```bash # Enable extended mode in Claude Code claude mcp add --scope user memorygraph -- memorygraph --profile extended ``` See [TOOL_PROFILES.md](docs/TOOL_PROFILES.md) for complete tool list and details. --- ## Installation Options ### pipx (Recommended) ```bash pipx install memorygraphMCP # Core mode (default, SQLite) pipx install "memorygraphMCP[neo4j]" # With Neo4j backend support pipx install "memorygraphMCP[falkordblite]" # With FalkorDBLite backend (embedded) pipx install "memorygraphMCP[ladybugdb]" # With LadybugDB backend (embedded) pipx install "memorygraphMCP[falkordb]" # With FalkorDB backend (client-server) ``` ### pip ```bash pip install --user memorygraphMCP ``` ### Docker ```bash docker compose up -d # SQLite docker compose -f docker-compose.neo4j.yml up -d # Neo4j ``` ### uvx (Quick Test) ```bash uvx memorygraph --version # No install needed ``` | Method | Best For | Persistence | |--------|----------|-------------| | pipx | Most users | Yes | | pip | PATH already configured | Yes | | Docker | Teams, production | Yes | | uvx | Quick testing | No | See [CONFIGURATION.md](docs/CONFIGURATION.md) for detailed options. --- ## Claude Code Web Support MemoryGraph works in Claude Code Web (remote) environments via project hooks. ### Quick Setup Copy the hook files to your project: ```bash # From memorygraph repo cp -r examples/claude-code-hooks/.claude /path/to/your/project/ # Commit to your repo cd /path/to/your/project git add .claude/ git commit -m "Add MemoryGraph auto-install hooks" ``` When you open this project in Claude Code Web, MemoryGraph installs automatically. ### Persistent Storage (Optional) Remote environments are ephemeral. For persistent memories, configure cloud storage in your Claude Code Web environment variables: | Variable | Description | |----------|-------------| | `MEMORYGRAPH_API_KEY` | API key from memorygraph.dev (coming soon) | | `MEMORYGRAPH_TURSO_URL` | Your Turso database URL | | `MEMORYGRAPH_TURSO_TOKEN` | Your Turso auth token | See [Claude Code Web Setup](docs/claude-code-web.md) for detailed instructions. --- ## Configuration ### Claude Code CLI ```bash # Core mode (default) claude mcp add --scope user memorygraph -- memorygraph # Extended mode claude mcp add --scope user memorygraph -- memorygraph --profile extended # Extended mode with Neo4j backend claude mcp add --scope user memorygraph \ --env MEMORY_NEO4J_URI=bolt://localhost:7687 \ --env MEMORY_NEO4J_USER=neo4j \ --env MEMORY_NEO4J_PASSWORD=password \ -- memorygraph --profile extended --backend neo4j # Cloud backend (multi-device sync, zero setup) claude mcp add --scope user memorygraph \ --env MEMORYGRAPH_API_KEY=mg_your_key_here \ -- memorygraph --backend cloud ``` > **Get your API key**: Sign up at [memorygraph.dev](https://memorygraph.dev) to get your free API key. ### Other MCP Clients ```json { "mcpServers": { "memorygraph": { "command": "memorygraph", "args": ["--profile", "extended"] } } } ``` See [CONFIGURATION.md](docs/CONFIGURATION.md) for all options. ### Recommended: Add to CLAUDE.md For best results, add this to your `CLAUDE.md` or project instructions: ```markdown ## Memory Tools When recalling past work or learnings, always start with `recall_memories` before using `search_memories`. The recall tool has optimized defaults for natural language queries (fuzzy matching, relationship context included). ``` This helps Claude use the optimal tool for memory recall. --- ## Usage ### Store Memories ```json { "tool": "store_memory", "content": "Use bcrypt for password hashing", "memory_type": "CodePattern", "tags": ["security", "authentication"] } ``` ### Recall Memories (Recommended) ```json { "tool": "recall_memories", "query": "authentication security" } ``` Returns fuzzy-matched results with relationship context and match quality hints. ### Search Memories (Advanced) ```json { "tool": "search_memories", "query": "authentication", "search_tolerance": "strict", "limit": 5 } ``` Use when you need exact matching or advanced filtering. ### Create Relationships ```json { "tool": "create_relationship", "from_memory_id": "mem_123", "to_memory_id": "mem_456", "relationship_type": "SOLVES" } ```  See [docs/examples/](docs/examples/) for more use cases. --- ## Memory Best Practices ### Why Memories Aren't Automatic MemoryGraph is an MCP tool provider, not an autonomous agent. This means: - **Claude needs to be prompted** to use the memory tools - **You control what gets stored** - nothing is saved without explicit instruction - **Configuration is key** - Add memory protocols to your CLAUDE.md for consistent behavior This design gives you full control over your memory graph, but requires setup to work effectively. ### How to Encourage Memory Creation #### 1. Configure CLAUDE.md (Recommended) Add a memory protocol to `~/.claude/CLAUDE.md` for persistent behavior across all sessions: ```markdown ## Memory Protocol ### REQUIRED: Before Starting Work You MUST use `recall_memories` before any task. Query by project, tech, or task type. ### REQUIRED: Automatic Storage Triggers Store memories on ANY of: - **Git commit** → what was fixed/added - **Bug fix** → problem + solution - **Version release** → summarize changes - **Architecture decision** → choice + rationale - **Pattern discovered** → reusable approach ### Timing Mode (default: on-commit) `memory_mode: immediate | on-commit | session-end` ### Memory Fields - **Type**: solution | problem | code_pattern | fix | error | workflow - **Title**: Specific, searchable (not generic) - **Content**: Accomplishment, decisions, patterns - **Tags**: project, tech, category (REQUIRED) - **Importance**: 0.8+ critical, 0.5-0.7 standard, 0.3-0.4 minor - **Relationships**: Link related memories when they exist Do NOT wait to be asked. Memory storage is automatic. ``` #### 2. Use Trigger Phrases Claude responds well to explicit memory-related requests: **For storing**: - "Store this for later..." - "Remember that..." - "Save this pattern..." - "Record this decision..." - "Create a memory about..." **For recalling**: - "What do you remember about...?" - "Have we solved this before?" - "Recall any patterns for..." - "What did we decide about...?" **For session management**: - "Summarize and store what we accomplished today" - "Store a summary of this session" - "Catch me up on this project" (uses stored memories) #### 3. Establish Workflow Habits **Start of session**: ``` You: "What do you remember about the authentication system?" Claude: [Uses recall_memories to find relevant context] ``` **During work**: ``` You: "We fixed the Redis timeout by increasing the connection pool to 50. Store this solution." Claude: [Uses store_memory, then create_relationship to link to the problem] ``` **End of session**: ``` You: "Store a summary of what we accomplished today" Claude: [Creates a task-type memory with summary and links] ``` #### 4. Project-Specific Configuration For team projects or specific repositories, add `.claude/CLAUDE.md` to the project: ```markdown ## Project Memory Protocol This project uses MemoryGraph for team knowledge sharing. ### When to Store - Solutions to project-specific problems - Architecture decisions and rationale - Deployment procedures and gotchas - Performance optimizations - Bug fixes and root causes ### Tagging Convention Always include these tags: - Project name: "my-app" - Component: "auth", "api", "database", etc. - Type: "fix", "feature", "optimization", etc. ### Example When fixing a bug: 1. Store the problem (type: problem) 2. Store the solution (type: solution) 3. Link them: solution SOLVES problem 4. Tag both with component and "bug-fix" ``` ### Memory Types Guide Choose the right type for better organization: | Type | Use For | Example | |------|---------|---------| | **solution** | Working fixes and implementations | "Fixed N+1 query with eager loading" | | **problem** | Issues encountered | "Database deadlock under high concurrency" | | **code_pattern** | Reusable patterns | "Repository pattern for database access" | | **decision** | Architecture choices | "Chose PostgreSQL over MongoDB for transactions" | | **task** | Work completed | "Implemented user authentication" | | **technology** | Tool/framework knowledge | "FastAPI dependency injection best practices" | | **error** | Specific errors | "ImportError: module not found" | | **fix** | Error resolutions | "Added missing import statement" | ### Relationship Types Guide Common relationship patterns: ```markdown # Causal relationships problem --CAUSES--> error change --TRIGGERS--> bug # Solution relationships solution --SOLVES--> problem fix --ADDRESSES--> error pattern --IMPROVES--> code # Context relationships pattern --APPLIES_TO--> project solution --REQUIRES--> dependency pattern --WORKS_WITH--> technology # Learning relationships new_approach --BUILDS_ON--> old_approach finding --CONTRADICTS--> assumption result --CONFIRMS--> hypothesis ``` ### Example Workflows **Debugging workflow**: ``` 1. Encounter error → Store as type: error 2. Find root cause → Store as type: problem, link: error TRIGGERS problem 3. Implement fix → Store as type: solution, link: solution SOLVES problem 4. Result: Complete chain for future reference ``` **Feature development workflow**: ``` 1. Start: "Recall any patterns for user authentication" 2. Implement: [Work on feature] 3. Store: "Store this authentication pattern" → type: code_pattern 4. Link: pattern APPLIES_TO project 5. End: "Store summary of authentication implementation" ``` **Optimization workflow**: ``` 1. Identify issue → Store as type: problem 2. Test solutions → Store each as type: solution 3. Compare → Link: best_solution IMPROVES other_solutions 4. Document → Store decision with rationale ``` ### More Examples and Templates For comprehensive CLAUDE.md configuration examples including: - Domain-specific setups (web dev, ML, DevOps) - Team collaboration protocols - Migration strategies from other systems See: [CLAUDE.md Configuration Examples](docs/examples/CLAUDE_MD_EXAMPLES.md) --- ## Backends MemoryGraph supports 8 backend options to fit your deployment needs: | Backend | Type | Config | Native Graph | Zero-Config | Best For | |---------|------|--------|--------------|-------------|----------| | **sqlite** | Embedded | File path | No (simulated) | ✅ | Default, simple use | | **falkordblite** | Embedded | File path | ✅ Cypher | ✅ | Graph queries without server | | **ladybugdb** | Embedded | File path | ✅ Cypher | ✅ | Graph queries without server | | **falkordb** | Client-server | Host:port | ✅ Cypher | ❌ | High-performance production | | **neo4j** | Client-server | URI | ✅ Cypher | ❌ | Enterprise features | | **memgraph** | Client-server | Host:port | ✅ Cypher | ❌ | Real-time analytics | | **turso** | Cloud | URL + Token | No (simulated) | ❌ | Distributed SQLite, edge deployments | | **cloud** | Cloud | API Key | ✅ Cypher | ❌ | MemoryGraph Cloud (production ready) | **New: FalkorDB Options** - **FalkorDBLite**: Zero-config embedded database with native Cypher support, perfect upgrade from SQLite - **LadybugDB**: Leading columnar embedded graph database with Cypher support - **FalkorDB**: Redis-based graph DB with 500x faster p99 than Neo4j ([docs](https://docs.falkordb.com/)) **New: Cloud Backend** - **Multi-device sync**: Access your memories from anywhere - **Team collaboration**: Share memories with your team - **Automatic backups**: Never lose your knowledge graph - **Zero maintenance**: No database setup required See [CONFIGURATION.md](docs/CONFIGURATION.md) for setup details and [Cloud Backend Guide](docs/CLOUD_BACKEND.md) for cloud-specific configuration. --- ## Multi-Tenancy (v0.10.0+) MemoryGraph now supports optional multi-tenancy for team memory sharing and organizational deployments.
