Javadoc MCP

A Node.js-based MCP server that provides intelligent search capabilities for Java documentation.

- Fuzzy Search: Powered by Fuse.js for intelligent matching
- Multiple Search Types: Classes, methods, constructors, and fields
- Data Deduplication: Automatic merging of duplicate entries
- Statistics: Get overview of documentation coverage
- Claude Integration: Seamless integration with Claude Desktop

npx @io.emop/mcp-javadoc-server --javadoc-path /path/to/javadoc-json

Contains example JSON documentation files generated from various Java projects for testing and reference purposes.

<plugin> <groupId>io.github.beamliu</groupId> <artifactId>java-docs-json-doclet</artifactId> <version>0.1.1</version> </plugin>

# Using npx (recommended, no installation needed) npx @io.emop/mcp-javadoc-server --javadoc-path /path/to/javadoc-json

npx @modelcontextprotocol/inspector npx -y @io.emop/mcp-javadoc-server -- --javadoc-path /path/to/javadoc-json

Once configured, you can use these commands in Claude Desktop:

- Search all items:search_all("ArrayList")
- Search classes:search_classes("HashMap")
- Search methods:search_methods("toString")
- Get class details:get_class_details("java.util.List")
- Get statistics:get_stats()

For projects using Lombok, configure the delombok process:
