check_maven_version_exists
Check if a specific version of a Maven dependency exists
LABSCO SUMMARY
The three questions a dependency bump actually raises.
Excluding pre-releases by default on both the latest-release and the list tools is the right default, and it removes the usual confusion where a release candidate looks like the newest version. check_maven_version_exists is the one that heads off a whole class of build failure: the version somebody pasted into a pom either exists or it does not, and finding out costs one call rather than one failed build and a stack trace.
What it is
A three-tool Maven dependency lookup covering the latest release, a version existence check, and the version list in deploy order.
What you get
- get_latest_release for a dependency, excluding pre-releases by default
- check_maven_version_exists, answering whether a named version of a dependency is actually published
- list_maven_versions in deploy order with the most recent first, with a depth limit and the same pre-release exclusion
Requirements
Nothing — no account, no key.
Setup effort
One command — npx mcp-maven-deps
USE CASES
01
Bumping a dependency nobody has touched in a year
Ask for the current release of the coordinate, then read the version list in deploy order to see how far the jump is and whether a patch was published after the minor you are sitting on.
02
Confirming a version someone quoted in an issue
Check that the exact version string exists before pinning to it, and put it next to the current release so you know whether the pin moves you forward or back.
3 tools

get_latest_release
Get the latest release version of a Maven dependency (excludes pre-releases by default)
