+# Neo4j GraphRAG Context Provider
+
+The Neo4j GraphRAG Context Provider adds Retrieval Augmented Generation (RAG) capabilities to Agent Framework agents using a Neo4j knowledge graph. It supports vector, fulltext, and hybrid search modes, with optional graph traversal to enrich results with related entities via custom Cypher queries.
+
+For knowledge graph scenarios where relationships between entities matter, this provider retrieves relevant subgraphs rather than isolated text chunks, giving agents richer context for generating responses.
+
+## Why use Neo4j for GraphRAG?
+
+- **Graph enhanced retrieval**: Standard vector search returns isolated chunks; graph traversal follows connections to surface related entities, giving agents richer context.
+- **Flexible search modes**: Combine vector similarity, keyword/BM25, and graph traversal in a single query.
+- **Custom retrieval queries**: Cypher queries let you control exactly which relationships to traverse and what context to return.
+
+> [!NOTE]
+> Neo4j offers two separate integrations for Agent Framework. This provider (`agent-framework-neo4j`) is for **GraphRAG** — searching an existing knowledge graph to ground agent responses. For **persistent memory** that learns from conversations and builds a knowledge graph over time, see the [Neo4j Memory Provider](./neo4j-memory.md).

+- Environment variables set: `NEO4J_URI`, `NEO4J_USERNAME`, `NEO4J_PASSWORD`, `AZURE_AI_PROJECT_ENDPOINT`
+- Azure CLI credentials configured (`az login`)
+- Python 3.10 or later
+
+## Installation
+
+```bash
+pip install agent-framework-neo4j
+```
+
+## Usage
+
+```python
+from agent_framework import Agent
+from agent_framework.azure import AzureAIClient
+from agent_framework_neo4j import Neo4jContextProvider, Neo4jSettings, AzureAISettings, AzureAIEmbedder
+from azure.identity.aio import AzureCliCredential

+    endpoint=azure_settings.inference_endpoint,
+    credential=credential,
+    model=azure_settings.embedding_model,
+)
+
+neo4j_provider = Neo4jContextProvider(
+    uri=neo4j_settings.uri,

+    top_k=5,
+    retrieval_query="""
+        MATCH (node)-[:FROM_DOCUMENT]->(doc:Document)
+        OPTIONAL MATCH (doc)<-[:FILED]-(company:Company)
+        RETURN node.text AS text, score, doc.title AS title, company.name AS company
+        ORDER BY score DESC
+    """,
+)
+
+async with (
+    neo4j_provider,
+    AzureAIClient(credential=credential, project_endpoint=azure_settings.project_endpoint) as client,
+    Agent(
+        client=client,
+        instructions="You are a financial analyst assistant.",
+        context_providers=[neo4j_provider],
+    ) as agent,
+):
+    session = agent.create_session()
+    response = await agent.run("What risks does Acme Corp face?", session=session)
+```
+
+## Key features
+
+- **Index-driven**: Works with any Neo4j vector or fulltext index
+- **Graph traversal**: Custom Cypher queries enrich search results with related entities
+- **Search modes**: Vector (semantic similarity), fulltext (keyword/BM25), or hybrid (both combined)

+# Neo4j Memory Provider
+
+The Neo4j Memory Provider gives Agent Framework agents persistent memory backed by a knowledge graph. Unlike RAG providers that retrieve from static knowledge bases, the memory provider stores and recalls agent interactions, automatically extracting entities and building a knowledge graph over time.
+
+The provider manages three types of memory:
+
+- **Short-term memory**: Conversation history and recent context
+- **Long-term memory**: Entities, preferences, and facts extracted from interactions
+- **Reasoning memory**: Past reasoning traces and tool usage patterns
+
+## Why use Neo4j for agent memory?
+
+- **Knowledge graph persistence**: Memories are stored as connected entities, not flat records, so the agent can reason about relationships between things it remembers.
+- **Automatic entity extraction**: Conversations are parsed into structured entities and relationships without manual schema design.
+- **Cross-session recall**: Preferences, facts, and reasoning traces persist across sessions and surface automatically via context providers.
+
+> [!NOTE]
+> Neo4j offers two separate integrations for Agent Framework. This provider (`neo4j-agent-memory`) is for **persistent memory** — storing and recalling agent interactions, extracting entities, and building a knowledge graph over time. For **GraphRAG** from an existing knowledge graph using vector, fulltext, or hybrid search, see the [Neo4j GraphRAG Context Provider](./neo4j-graphrag.md).

+    },
+)
+
+memory_client = MemoryClient(settings)
+
+async with memory_client:
+    memory = Neo4jMicrosoftMemory.from_memory_client(
+        memory_client=memory_client,
+        session_id="user-123",
+    )
+    tools = create_memory_tools(memory)
+
+    async with (
+        AzureAIClient(
+            credential=AzureCliCredential(),
+            project_endpoint=os.environ["AZURE_AI_PROJECT_ENDPOINT"],
+        ) as client,
+        Agent(
+            client=client,
+            instructions="You are a helpful assistant with persistent memory.",
+            tools=tools,
+            context_providers=[memory.context_provider],

+        session = agent.create_session()
+        response = await agent.run("Remember that I prefer window seats on flights.", session=session)

+## Key features
+
+- **Bidirectional**: Automatically retrieves relevant context before invocation and saves new memories after responses
+- **Entity extraction**: Builds a knowledge graph from conversations using a multi-stage extraction pipeline
+- **Preference learning**: Infers and stores user preferences across sessions
+- **Memory tools**: Agents can explicitly search memory, remember preferences, and find entity connections
