How do I install the zero vector 3 mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `ZERO_VECTOR_BASE_URL`, `ZERO_VECTOR_API_KEY`, `ZERO_VECTOR_V3_BASE_URL`, `ZERO_VECTOR_V3_API_KEY`, `POSTGRES_URL`, `REDIS_URL`, `OPENAI_API_KEY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Zero Vector 3 MCP Server?

A complete AI persona memory management system combining a high-performance hybrid vector-graph database server with advanced LangGraph workflow orchestration and a Model Context Protocol (MCP) interface for sophisticated AI memory, relationship understanding, and multi-agent coordination.

Requirements

Node.js 18.0.0 or higher - 4GB+ available RAM (recommended for v3.0) - PostgreSQL (for LangGraph checkpointing) - Redis (for performance caching) - Git
