Octopus MCP Server is an MCP server that provides a high-performance, persistent knowledge base interface built with Rust for AI assistants and development workflows. It connects Model Context Protocol clients directly to hybrid datastores, supporting technologies such as Qdrant for vector embeddings, Neo4j for graph structures, and Redis for fast in-memory caching and retrieval. Software engineers, data architects, and AI developers use this server to equip their local language model setups with long-term memory, retrieval-augmented generation pipelines, and structured relational context. By combining vector similarity search and graph-based relationship tracking in a unified Rust implementation, the server enables AI agents to query multidimensional data environments efficiently without losing contextual history across sessions. The architecture is designed for local deployment, giving developers full control over data privacy and storage configurations while minimizing response latency. Through standard protocol interactions, users can write, update, and search knowledge records spanning across relational graph nodes, embedded vectors, and operational cache layers directly from supported AI interfaces.

Part of MCP Servers
Octopus MCP Server is an open-source, Rust-based server implementing the Model Context Protocol. It bridges AI assistants with persistent, hybrid storage solutions. By connecting to Qdrant, Neo4j, and Redis, it allows language models to store, manage, and retrieve complex structured graphs, vector embeddings, and cached data during ongoing interactions.
Octopus MCP Server is designed to support hybrid datastore deployments. It integrates with Qdrant for semantic vector search, Neo4j for graph-based knowledge representations, and Redis for fast in-memory key-value operations. This enables multi-modal retrieval strategies that combine graph traversal and vector indexing in a single deployment.
Yes, Octopus MCP Server is open source. You can access its source code, build instructions, and issue tracker on GitHub at https://github.com/ar-hox/octopus-mcp-server. The community can inspect, modify, and deploy the server in local environments without proprietary software restrictions.
Octopus MCP Server works with any standard client that supports the Model Context Protocol, including Claude Desktop, Cursor, and custom agentic frameworks. Once configured in the client configuration file, the AI assistant can issue standard MCP tool and resource commands directly to the server.
Because the repository provides the primary build and configuration instructions, you should clone the source code from https://github.com/ar-hox/octopus-mcp-server and follow the documented Rust compilation steps. Afterward, register the resulting executable in your client configuration file alongside the connection details for your datastores.
