概要

What is Javadoc Mcp?

Javadoc Mcp is a Model Context Protocol (MCP) server that allows AI assistants to browse JavaDoc documentation using Maven coordinates. It is designed for developers who need programmatic access to Java library documentation via an AI or CLI tool.

How to use Javadoc Mcp?

Install via npx -y javadoc-mcp or npm install -g javadoc-mcp, then configure your MCP client (e.g., Claude Code or Claude Desktop) with the appropriate command and arguments in settings.json or claude_desktop_config.json. After setup, tools are automatically available to the AI assistant.

Key features of Javadoc Mcp

  • Five MCP tools for browsing JavaDoc: list_packages, list_classes, get_class, get_member, and search.
  • Reads from the local Maven repository (~/.m2/repository) or auto-fetches missing -javadoc.jar files.
  • Uses cheerio for HTML parsing and adm-zip to read directly from JARs without extracting to disk.
  • Implemented in TypeScript with the @modelcontextprotocol/sdk.

Use cases of Javadoc Mcp

  • An AI assistant looks up a class’s method signatures and documentation while writing Java code.
  • A developer searches for a specific type or member across multiple Java libraries.
  • Automated tooling browses the package structure of a Maven artifact to generate API summaries.

よくある質問

1

What are the system requirements?

Node.js 18+ is required, and the `mvn` command must be available in `PATH`.

2

Where are JavaDoc JARs stored locally?

Javadoc Mcp uses the local Maven repository, typically located at `~/.m2/repository`, or the path specified in `~/.m2/settings.xml` under `<localRepository>`.

3

How do I refresh the documentation for a library?

Delete the corresponding `*-javadoc.jar` from your local Maven repository for that artifact; the server will fetch it again on the next invocation.

4

How is Javadoc Mcp configured with MCP clients?

Add a server entry to your MCP client configuration (e.g., `~/.claude/settings.json` or `claude_desktop_config.json`) with `"command": "npx"` and `"args": ["-y", "javadoc-mcp"]`, or `"command": "javadoc-mcp"` if globally installed.

5

Does Javadoc Mcp support authentication for private Maven repositories?

The README does not mention any authentication mechanisms; it assumes public Maven Central or repositories accessible via standard Maven settings.
