Installation

Prerequisites

• Node.js 18.0.0 or higher
• npm or yarn package manager

Setup

1. Clone or download the MCP server files
2. Install dependencies:

npm install

1. Configure your MCP client (Claude Desktop, etc.) to use this server:

Claude Desktop Configuration: Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "directory-context": {
      "command": "node",
      "args": ["path/to/your/server.js"],
      "cwd": "your-default-working-directory"
    }
  }
}

Alternative Configuration: Use the provided mcp-json-config.json as a template and update the paths accordingly.

Usage

Setting Up Your Working Directory

Before using any features, set your working directory:

set_working_directory(directory="/path/to/your/project")

Directory Analysis Tools

Get Directory Structure

get_directory_structure(
  max_depth=10,           // Maximum traversal depth
  include_hidden=false,   // Include hidden files/directories
  file_types=[".js", ".py", ".md"]  // Filter by extensions
)

Analyze Project Context

analyze_project_context(
  include_code_analysis=true,    // Include complexity analysis
  focus_files=["specific_file.js"]  // Focus on specific files
)

Search Files

search_files(
  query="function myFunction",  // Search query
  file_types=[".js", ".ts"],   // File types to search
  is_regex=false,              // Use regex matching
  max_results=50               // Maximum results
)

Git Context

get_git_context(
  include_diff=true,     // Include working directory changes
  commit_count=10        // Number of recent commits
)

File Management Tools

Create Files

create_file(
  path="src/new-component.js",
  content="const MyComponent = () => { ... }",
  encoding="utf8",
  overwrite=false
)

Update Files

update_file(
  path="src/config.js",
  updates=[
    {
      search: "oldValue: 'old'",
      replace: "newValue: 'new'",
      regex: false,
      all: true
    }
  ],
  backup=true
)

Append to Files

append_to_file(
  path="README.md",
  content="## New Section\nContent here...",
  newline_before=true
)

Delete Files

delete_file(
  path="old-file.js",
  backup=true  // Creates .deleted backup
)

Rename/Move Files

rename_file(
  old_path="old-name.js",
  new_path="new-name.js",
  overwrite=false
)

Create Directories

create_directory(
  path="src/components/new-feature",
  recursive=true
)

Batch Operations

Execute multiple operations atomically:

batch_file_operations(
  operations=[
    {
      operation: "create",
      params: {
        path: "src/component.js",
        content: "export default () => {}"
      }
    },
    {
      operation: "update",
      params: {
        path: "src/index.js",
        updates: [...]
      }
    }
  ],
  rollback_on_error=true
)

Project Type Detection

The server automatically detects project types based on configuration files:

• Node.js/JavaScript: package.json
• Python: requirements.txt
• Rust: Cargo.toml
• Go: go.mod
• Java: pom.xml, build.gradle
• PHP: composer.json
• Ruby: Gemfile
• Docker: Dockerfile, docker-compose.yml
• And more...

File Priority Detection

The server identifies important files automatically:

• Configuration files (package.json, config.js, etc.)
• Entry points (index.js, main.py, app.js)
• Documentation (README.md, docs)
• Docker files
• Environment files (.env)

Resource Exposure

Important files are automatically exposed as MCP resources, making them easily accessible to AI assistants without explicit file reading requests.

Error Handling and Safety Features

• Backup Creation: Automatic backups for destructive operations
• Collision Detection: Prevents accidental overwrites
• Transaction Rollback: Batch operations can be fully rolled back on error
• Path Validation: Ensures operations stay within working directory bounds
• Detailed Error Messages: Comprehensive error reporting for debugging
