ArcadeDB MCP Server

This is a built-in MCP server that ships with ArcadeDB, giving Claude direct access to a multi-model database that handles graphs, documents, vectors, time series, and key-value data. You can query with SQL, Cypher, Gremlin, GraphQL, or MongoDB query language, all through stdio transport. It's built for scenarios where you need Claude to work with complex data relationships without manually shuttling results back and forth. The database itself runs 70+ graph algorithms natively and supports parallel query execution, so you can ask Claude to traverse social networks, analyze time series patterns, or run vector similarity searches against your embedded data. Runs in Docker and speaks multiple protocol dialects, making it a solid choice when your agent needs to operate on richly structured data that doesn't fit neatly into tables.
