How do I install the maven indexer mcp server?

Use a recorded configuration for your client, replace example credential values and paths, and verify the documented runtime. Restart or reconnect the client, then inspect the available tools.

What credentials does it need?

It reads `MAVEN_REPO`, `GRADLE_REPO_PATH`, `INCLUDED_PACKAGES`, `MAVEN_INDEXER_CFR_PATH`, `VERSION_RESOLUTION_STRATEGY` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Maven Indexer MCP Server?

MCP server for indexing local Maven repository

What it actually does

A Model Context Protocol (MCP) server that indexes your local Maven repository (~/.m2/repository) and Gradle cache ( ~/.gradle/caches/modules-2/files-2.1) to provide AI agents with tools to search for Java classes, method signatures, and source code.

Semantic Class Search — Search for classes by name or purpose
Inheritance Search — Find all implementations of an interface or subclasses of a class
On-Demand Analysis — Extracts method signatures and Javadocs directly from JARs
Source Code Retrieval — Provides full source code if available
Real-time Monitoring — Automatically updates the index when repositories change
