Nexus
Connects to Sonatype Nexus Repository Manager 3 (OSS or Pro) through the standard REST API v1, exposing six read-only tools for querying Maven, Python, and Docker repositories. You get artifact search, version listing with pagination via continuation tokens, and Docker image/tag enumeration. Built on FastMCP with SSE transport by default, though it supports streamable-http as well. Authentication happens per-request through HTTP headers, so no hardcoded credentials in your config. Useful when you need an AI assistant to search for specific artifact versions, check what's published in your private registries, or answer questions about package availability without opening a browser.
