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

set up

Prerequisites

  • Python 3.10 or later

  • uv

install

# uvのインストール
$ curl -LsSf https://astral.sh/uv/install.sh | sh

$ cd /path/to/mcp-source-relation
# ライブラリのインストール
$ uv sync

Claude for Desktop Settings

Add the following to claude_desktop_config.json :

{
    "mcpServers": {
        "source-relation": {
            "command": "uv",
            "args": [
                "--directory",
                "/path/to/mcp-source-relation",  # このプロジェクトディレクトリの絶対パスに書き換えてください
                "run",
                "source_relation.py"
            ]
        }
    }
}

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

`/Users/owa/GitHub/mcp-source-relation/` のソースコードの依存関係を確認してみましょう。

依存関係の分析結果から、以下のような構造が確認できます:

1. メインの解析モジュール: `src/source_analyzer.py`
   - 各言語固有の解析モジュールを利用しています(Ruby, Python, TypeScript, Rust)

2. 言語別の解析モジュール:
   - `src/analyzers/ruby.py`
   - `src/analyzers/python.py` 
   - `src/analyzers/typescript.py`
   - `src/analyzers/rust.py`
   - すべて `src/analyzers/base.py` を継承しています

3. 共通基盤:
   - `src/analyzers/base.py`: 基本的な解析機能を提供
   - `src/utils/path.py`: パス操作のユーティリティ
   - `src/configs/typescript.py`: TypeScript固有の設定

特徴的な点:
- 各言語の解析モジュールは共通の基底クラス(base.py)を継承しており、一貫性のある設計になっています
- TypeScriptのみ独自の設定ファイル(configs/typescript.py)を持っています
- パス操作は共通のユーティリティモジュール(utils/path.py)に集約されています

この構造から、新しい言語のサポートを追加する場合は、`src/analyzers/` に新しいモジュールを追加し、`base.py` を継承することで実現できる設計になっていることがわかります。

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:

{
  "dependencies": {
    "components/Button.tsx": [
      "types/index.ts",
      "utils/theme.ts"
    ],
    "pages/index.tsx": [
      "components/Button.tsx",
      "utils/api.ts"
    ]
  }
}

All paths are relative to the src directory.

Supported import formats

TypeScript/JavaScript

  • import { Component } from './Component'

  • import type { Type } from '@/types'

  • import './styles.css'

  • require('./module')

  • Alias paths ( @/components/... )

Python

  • import module

  • from module import name

  • from .module import name

  • from ..module import name

Ruby

  • require 'module'

  • require_relative './module'

  • Require without extension

Rust

  • mod module;

  • use crate::module;

  • use super::module;

  • use self::module;
