MCP Source Relation Server

MCP Source Relation Server

This is an MCP server that analyzes the relationships of source code under src directory of a specified directory. It analyzes import statements for each language and identifies dependencies between files. By incorporating it into Claude, Claude can quickly check the dependencies of a project and help identify related files.

function

• Supports multi-language import parsing
  • TypeScript/JavaScript: import statement, require statement
  • Python: import statement, from ... import statement
  • Ruby: require statement, require_relative statement
  • Rust: mod declaration, use statement
• Corresponds to path aliases in tsconfig.json (such as @/components/... )
• Supports special features for each language
  • Python: __init__.py , relative imports
  • Rust: mod.rs pattern
  • TypeScript: alias, index.ts
  • Ruby: require without extension

How to use

Use by Claude

/Users/xxx/GitHub/xxx/ のソースの依存関係を確認してand instruct it like this, it will work

If you specify a directory, the src directory under it will be analyzed. If you specify a file, the analysis will be based on that file. It also supports path input from the prompt. To use it with a prompt, select Attach from MCP -> Choose an integration -> source-relation .

Output Format

The analysis results are output in JSON format as follows:

All paths are relative to the src directory.
