Best Neptune MCP Servers
Neptune is a metadata store for MLOps, built for teams that run a lot of experiments. It gives you a central place to log, store, display, organize, compare, and query all your model-building metadata.
Why this server?
Provides a stub driver for Neptune, a graph database, enabling integration and extensibility.
Why this server?
Enables AI agents to interact with Amazon Neptune and other Gremlin-compatible graph databases through natural language, providing tools for schema discovery, graph queries, relationship analysis, data import/export, and automatic enum discovery for property values.
AlicenseNot gradedqualityCmaintenanceEnables AI assistants to interact with Gremlin-compatible graph databases through natural language, supporting schema discovery, complex graph queries, relationship analysis, and data import/export operations.6 npm9MITWhy this server?
Provides cost optimization checks for Amazon Neptune databases, identifying idle or over-provisioned instances.
AlicenseNot gradedqualityDmaintenanceEnables scanning AWS accounts for cost optimization opportunities by reading resource configurations and pricing data, without making any modifications.23MITWhy this server?
Allows querying and managing AWS Neptune graph databases with support for read-only mode, safety rails, and structured results.
AlicenseNot gradedqualityAmaintenanceQuarry provides an MCP server for database querying with safety rails, allowing AI agents to execute SQL queries, list connections, and manage schemas through a structured interface.231 PyPI4MITWhy this server?
Talks directly to a Neptune Apex aquarium controller's local REST API (e.g. Apex, AC6L, AOS 5.15L firmware) over stdio, without MQTT, Home Assistant or Neptune Fusion cloud. Read-only by default, it exposes tools to query system identity/firmware/modules/feed state, current probe readings, water parameters (temp, pH, ORP, salinity, Trident chemistry), power summary (watts/amps, voltage, top consumers), digital float switch states, outlet states (AUTO/ON/OFF, energized, pump mode), config sections, probe history and drift statistics, outlet on/off event logs, duty-cycle analytics, and outlet program text. When writes are explicitly enabled it can set outlets to AUTO/ON/OFF, start and safely cancel feed cycles, and diff/backup/apply/re-verify outlet program edits including MXM tdata time tables, with protected outlets, credential redaction and rate-limit-aware caching.
AlicenseNot gradedqualityBmaintenanceEnables interaction with Neptune Apex aquarium controllers through their local REST API, providing read-only monitoring of probes, outlets, power, inputs, and history by default, with opt-in write tools for outlet control, feed cycles, and guarded program edits.AGPL 3.0
