Level ALocal

An Amazon Neptune MCP server that allows for fetching status, schema, and querying using openCypher, Gremlin, and SPARQL for Neptune Database and openCypher for Neptune Analytics.

Overview

An MCP server for Amazon Neptune Database and Neptune Analytics. It fetches graph status (available or unavailable), returns the graph schema as text, and runs openCypher and Gremlin queries against the configured graph (openCypher for Neptune Analytics). The server executes any query it receives, including mutating and read-only actions, so IAM permissions should control data plane operations.
