MCP server for PMD static code analyzer - run code analysis and detect duplicates
io.github.roeiba/pmd — MCP server for PMD
This MCP server integrates the PMD static code analyzer to run code analysis and detect duplicates. Its purpose is to expose PMD’s capabilities through an MCP server interface for downstream tooling that consumes context from MCP.
🛠️ Key Features
Runs PMD static code analysis
Detects duplicate code
🚀 Use Cases
Static analysis workflows using PMD
Automated duplicate-detection checks in codebases
⚡ Developer Benefits
Enables PMD analysis via MCP server integration
Supports developer tooling that consumes MCP server capabilities
⚠️ Limitations
Available metadata describes PMD analysis and duplicate detection, but does not specify additional tools, endpoints, or configuration options
PMD is an extensible multilanguage static code analyzer. It finds common programming flaws like unused variables,
empty catch blocks, unnecessary object creation, and so forth. It's mainly concerned with Java and
Apex, but supports 16 other languages. It comes with 400+ built-in rules. It can be
extended with custom rules. It uses JavaCC and Antlr to parse source files into abstract syntax trees
(AST) and runs rules against them to find violations. Rules can be written in Java or using a XPath query.
Currently, PMD supports Java, JavaScript, Salesforce.com Apex and Visualforce,
Kotlin, Swift, Modelica, PL/SQL, Apache Velocity, JSP, WSDL, Maven POM, HTML, XML and XSL.
Scala is supported, but there are currently no Scala rules available.
Additionally, it includes CPD, the copy-paste-detector. CPD finds duplicated code in
Coco, C/C++, C#, CSS, Dart, Fortran, Gherkin, Go, Groovy, HTML, Java, JavaScript, JSP, Julia, Kotlin,
Lua, Matlab, Modelica, Objective-C, Perl, PHP, PL/SQL, Python, Ruby, Salesforce.com Apex and
Visualforce, Scala, Swift, T-SQL, Typescript, Apache Velocity, WSDL, XML and XSL.
