VelesDB is a local-first database for AI agent memory that combines vector search, graph queries, and typed columnar storage in one offline Rust binary. It also includes a built-in memory SDK and an MCP server for storing memories, linking them, and explaining recalls with a `why()` evidence trail.
From the registry: Offline agentic memory: remember/recall/relate/forget/why over a fused vector+graph+columnar engine

This server lives in a monorepo. The README covers the whole collection, so we can't extract a single canonical install. This README is for the VelesDB monorepo and mentions a local MCP server in crates/velesdb-memory, but it does not provide usable MCP launch/config details (command/args/env) for that server in this README.
