Installation
Prerequisites
- Node.js 18.0.0 or higher
- npm or yarn package manager
Setup
- Clone or download the MCP server files
- Install dependencies:
npm install
- 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
