"An overview of knowledge graphs" matching MCP servers:
- Alicense-qualityBmaintenanceAn embedded knowledge graph in one SQLite file, exposing a MCP server for agents to read and write entities and relationships with full audit trail and time travel.1MIT
- Flicense-qualityDmaintenanceA TypeScript MCP server for managing persistent knowledge graphs with entities, directional relations, and time-based observations. It enables users to create, search, and track structured information with built-in concurrency control and JSON file storage.
- AlicenseAqualityDmaintenanceConnects AI assistants to Tacit building digital twins to query buildings, equipment, sensors, and zones using natural language. It provides tools for exploring Brick-compliant knowledge graphs, fetching historical sensor data, and accessing site documents.4MIT
- FlicenseAqualityCmaintenanceEnables AI agents to build, populate, and search knowledge graphs by providing tools for entity extraction, relationship mapping, and graph traversal. It manages the underlying database infrastructure so users can create searchable knowledge bases from text through natural language commands.131
- FlicenseAqualityBmaintenanceEnables AI coding agents to query, create, and manage Mnemosyne knowledge graphs through SPARQL queries, RDF file uploads, and graph operations with OAuth authentication.233
- AlicenseAqualityAmaintenanceAI-native ontology engineering MCP server for OWL/RDF/SPARQL. Validate, query, diff, lint, version, and govern knowledge graphs via Oxigraph triple store.42398MIT
- AlicenseBqualityDmaintenanceProvides a scalable knowledge graph implementation for Model Context Protocol using Elasticsearch, enabling AI models to store and query information with advanced search capabilities, memory-like behavior, and multi-zone architecture.201620MIT
- AlicenseBqualityCmaintenanceA memory server for Claude that stores and retrieves knowledge graph data in DuckDB, enhancing performance and query capabilities for conversations with persistent user information.8659MIT
- AlicenseBqualityAmaintenanceA basic implementation of persistent memory using a local knowledge graph. This lets Claude remember information about the user across chats.978,10289,405Inno Setup
- FlicenseBqualityDmaintenanceEnables indexing and retrieving notes with full-text search using SQLite, plus building knowledge graphs to find relationships between concepts. Supports natural language note management, tagging, and semantic connections.16
- AlicenseCqualityDmaintenanceEnables AI assistants to use Neo4j knowledge graphs and Qdrant vector databases for hybrid reasoning, combining structured facts with semantic search for advanced knowledge management, research analysis, and standardized coding workflows.3020MIT
- Alicense-qualityDmaintenanceThis read-only MCP Server allows you to connect to Act-On data from Claude Desktop through CData JDBC Drivers. Free (beta) read/write servers available at https://www.cdata.com/solutions/mcpMIT
- Alicense-qualityDmaintenanceMaps Salesforce metadata into a Neo4j graph database, enabling AI agents to reason about schema and generate accurate SOQL queries.MIT
dooor-os-mcpofficial
Flicense-qualityBmaintenanceExposes Dooor OS workspace capabilities to MCP-compatible AI clients, enabling natural language querying of data sources, app and deployment inspection, agent and database management, and governance trace reading.- Alicense-qualityBmaintenanceAgentic RAG Knowledge Assistant is a secure, tenant-isolated MCP server built with FastAPI, PostgreSQL, and pgvector that enables document ingestion, semantic retrieval, and vector search over PDF, DOCX, and text files through authenticated MCP tools.MIT
- Alicense-qualityCmaintenanceAn MCP server that enables LLMs to query and reason over Active Directory attack graphs collected by BloodHound, providing attack paths, blast radius analysis, choke points, and defender remediation advice.1MIT
- Alicense-qualityCmaintenanceDynamic SQLite memory bank with semantic search, table management, and knowledge graphs for LLM agents.2MIT
- Alicense-qualityDmaintenanceEnhances the MCP memory server by implementing PouchDB for robust document storage and enabling the creation and management of a knowledge graph that captures interactions via language models.4MIT
- Alicense-qualityCmaintenanceEnables LLMs to manage file-based knowledge bases with dual storage (Markdown + SQLite). Supports creating, searching, and organizing articles across multiple knowledge bases with full-text search capabilities.143MIT
