cto-nexus-mcp-server

Read-only MCP server for searching Nexus Repository Manager 3.

Tools

Tool

Description

list_repositories

List all visible repositories

search_components

Search components (Docker, Maven, npm, PyPI…) by name/group/version/format

search_docker_tags

List Docker image tags for a given image, newest first

find_docker_image

Auto-discover a Docker image by base name, probing known namespace prefixes (oas/, orbis-u/, hdc/, local/, none)

get_latest_version

Get the single latest version of a component

Every tool takes host as first parameter (Nexus hostname, defaults to registry-nexus.orbis.dedalus.com). Only override if targeting a different Nexus instance — do not set it to a repository name. Credentials (NEXUS_USER / NEXUS_PASSWORD) are injected via ExternalSecret from AWS Secrets Manager (nexus/dev/credentials).
