Central Memory MCP Server (.NET)

Index page for the Central Memory MCP Server documentation.

Overview

A .NET 10 Azure Functions (isolated) implementation of a Model Context Protocol (MCP) memory & knowledge graph service. Provides durable, queryable project memory for AI assistants through HTTP-exposed MCP tool endpoints.

Capabilities

• Entities (typed nodes with observations & metadata)
• Relations (directed, typed edges)
• Observations (append-only time-stamped facts)
• Graph stats & temporal events
• Duplicate detection & merge operations
• Workspace isolation via workspaceName
• Health & readiness endpoints

Quick Start

dotnet restore
dotnet build
func start --port 7071
curl http://localhost:7071/api/health
curl http://localhost:7071/api/ready

Local storage:

AzureWebJobsStorage=UseDevelopmentStorage=true

MCP Tool Workflow (Recommended)

1. read_graph
2. upsert_entity
3. get_entity_relations
4. upsert_relation

Edge cases: Missing entities auto-created during relation/observation operations.

Directory Highlights

• Functions: HTTP endpoints (GraphFunctions.cs, HealthFunctions.cs)
• Services: Domain logic (KnowledgeGraphService.cs)
• Storage: Azure Table abstraction (TableStorageService.cs)
• Models: DTO contracts (GraphModels.cs)

Configuration

Edit appsettings.json (local). Set production values via environment variables:

AzureWebJobsStorage=DefaultEndpointsProtocol=https;AccountName=<name>;AccountKey=<key>;EndpointSuffix=core.windows.net
