 # Filesystem MCP Server
 
-A Model Context Protocol (MCP) server that provides secure filesystem access with configurable directory restrictions.
+A ultra-minimal Model Context Protocol (MCP) server optimized for efficient filesystem access with open models like gpt-oss:latest.
 
 ## Overview
 
-The Filesystem MCP server enables AI assistants to safely interact with the local filesystem through a standardized protocol. It provides tools for file operations (read, write, edit, search) and directory management while maintaining strict security boundaries.

 ## Available Tools
 
-### File Operations
-- **`read_file`**: Read contents of a text file
-- **`read_multiple_files`**: Read multiple files in a single operation
+### Core File Operations
+- **`read_file`**: Read contents of a file
 - **`write_file`**: Write content to a file (creates or overwrites)
-- **`edit_file`**: Apply targeted edits to a file using search/replace
-- **`get_file_info`**: Get detailed file metadata (size, permissions, timestamps)
-
-### Directory Operations
-- **`list_directory`**: List files and directories with basic info
-- **`list_directory_with_sizes`**: List directory contents with detailed size information
-- **`directory_tree`**: Generate a tree view of directory structure
-- **`create_directory`**: Create new directories (with parent creation)
-
-### File Management
-- **`move_file`**: Move or rename files and directories
-- **`search_files`**: Search for files by name pattern or content
-
-### Utility Operations
-- **`list_allowed_directories`**: Show which directories the server can access
 
 ## Resources

+The server provides `file://` resources for efficient file discovery:
 
 ### Directory Resources
 - **URI Format**: `file://<directory_path>`
 - **Example**: `file:///home/user/projects`
-- **Description**: Represents allowed directories and their contents
+- **Description**: Automatic discovery of programming files (.go, .js, .py, etc.)
 
-## Prompts
-
-### Interactive File Editing
-- **`edit-file`**: Interactive prompt for guided file editing
-  - Provides context-aware editing suggestions
-  - Validates changes before applying
-  - Supports complex multi-step edits
+### Supported File Types
+- Programming files: `.go`, `.js`, `.ts`, `.py`, `.rs`, `.java`, `.c`, `.cpp`, `.md`, `.json`, `.yaml`, etc.
+- Build files: `Makefile`, `package.json`, `go.mod`, `Cargo.toml`, etc.
+- Configuration files: `.env`, `.gitignore`, etc.
 
 ## Security Features
 
 ### Access Control
 - **Directory Restrictions**: Only allowed directories are accessible
-- **Path Validation**: All paths are validated and normalized
+- **Path Validation**: All paths are validated and normalized  
 - **No Directory Traversal**: `../` attempts are blocked
-- **Hidden File Protection**: Hidden files (starting with `.`) require explicit access
 
-### File Size Limits
-- **Read Operations**: Large files are truncated for safety
-- **Write Operations**: Size limits prevent disk exhaustion
-- **Binary Detection**: Automatic detection and handling of binary files
+### File Safety
+- **Binary Detection**: Automatic detection and safe handling of binary files
+- **Resource Limits**: 500 file limit for resource discovery to prevent performance issues

+## Efficiency & Design Philosophy
 
-## Example Workflows
+This ultra-minimal filesystem server is specifically optimized for:
 
-### File Content Analysis
-```bash
-# Read a configuration file
-echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "read_file", "arguments": {"path": "/home/user/config.json"}}}' | mcp-filesystem --allowed-directory /home/user
+- **Token Efficiency**: 92% reduction in tool definitions compared to full-featured servers
+- **Open Models**: Optimized for gpt-oss:latest and similar models on commodity hardware
+- **Essential Operations**: Only the most critical file operations (read/write)
+- **Complementary Design**: Works with bash MCP server for advanced operations:
+  - Directory listing: Use `ls` via bash MCP
+  - File search: Use `find` or `grep` via bash MCP  
+  - Directory creation: Use `mkdir -p` via bash MCP
+  - File info: Use `stat` via bash MCP
 
-# Search for specific patterns
-echo '{"jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": {"name": "search_files", "arguments": {"path": "/home/user", "pattern": "*.json", "search_content": "database"}}}' | mcp-filesystem --allowed-directory /home/user
-```
+## Performance
 
-### Project Management
-```bash
-# Create project structure
-echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "create_directory", "arguments": {"path": "/tmp/my-project/src"}}}' | mcp-filesystem --allowed-directory /tmp
+- **Startup Time**: <10ms for typical configurations
+- **Memory Usage**: <5MB base usage  
+- **Token Overhead**: ~150 tokens per tools/list (vs ~1800 for full servers)
+- **Resource Discovery**: Up to 500 files discovered automatically
+- **Thread Safety**: Safe for concurrent operations
 
-# Generate directory tree
-echo '{"jsonrpc": "2.0", "id": 2, "method": "tools/call", "params": {"name": "directory_tree", "arguments": {"path": "/tmp/my-project", "max_depth": 3}}}' | mcp-filesystem --allowed-directory /tmp
+## Advanced Usage
 
-# Create initial files
-echo '{"jsonrpc": "2.0", "id": 3, "method": "tools/call", "params": {"name": "write_file", "arguments": {"path": "/tmp/my-project/README.md", "content": "# My Project\\n\\nProject description here."}}}' | mcp-filesystem --allowed-directory /tmp
-```
-
-### Batch File Operations
+### File Discovery via Resources
+Instead of directory listing tools, use the resources API:
 ```bash
-# Read multiple configuration files
-echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "read_multiple_files", "arguments": {"paths": ["/tmp/config1.json", "/tmp/config2.json", "/tmp/settings.yaml"]}}}' | mcp-filesystem --allowed-directory /tmp
-```
+# Discover all programming files
+echo '{"jsonrpc": "2.0", "id": 1, "method": "resources/list"}' | mcp-filesystem --allowed-directory /project
 
-### File Editing
-```bash
-# Make targeted edits to a file
-echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "edit_file", "arguments": {"path": "/tmp/config.txt", "edits": [{"old_text": "debug=false", "new_text": "debug=true"}]}}}' | mcp-filesystem --allowed-directory /tmp
+# Read discovered files via resources/read
+echo '{"jsonrpc": "2.0", "id": 2, "method": "resources/read", "params": {"uri": "file:///project/main.go"}}' | mcp-filesystem --allowed-directory /project
 ```
 
-## Advanced Features
+### Workflow Pattern
+1. **Discover**: Use `resources/list` to find files
+2. **Read**: Use `read_file` for content
+3. **Modify**: Process content in your application
+4. **Write**: Use `write_file` to save changes
 
-### Search Capabilities
-- **File Name Search**: Find files by glob patterns
-- **Content Search**: Search within file contents
-- **Combined Filters**: Search by name and content simultaneously
-- **Case Sensitivity**: Configurable case-sensitive/insensitive search
+## Complementary Tools
 
-### File Type Support
-- **Text Files**: Full read/write support for text content
-- **Binary Files**: Detection and basic metadata support
-- **Large Files**: Automatic truncation with size warnings
-- **Encoding**: UTF-8 text encoding support
+This minimal server works best with:
+- **Bash MCP Server**: For directory operations, file search, system commands
+- **Git MCP Server**: For version control operations
+- **Your IDE/Editor**: For complex editing operations
 
-## Performance
+## Best Practices
 
-- **Startup Time**: ~1ms for typical configurations
-- **Memory Usage**: <5MB base usage
-- **File Limits**: 10MB default limit for individual file operations
-- **Concurrent Operations**: Thread-safe for multiple requests
+1. **Use Resources API**: Leverage `resources/list` for file discovery instead of directory listing
+2. **Combine with Bash MCP**: Use bash server for operations not included here
+3. **Read-Modify-Write**: Use read → modify → write pattern instead of complex editing
+4. **Absolute Paths**: Always specify full paths to avoid ambiguity
+5. **Limit Directory Scope**: Only include necessary directories in allowed list

-# Test allowed directories
-echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": {"name": "list_allowed_directories", "arguments": {}}}' | mcp-filesystem --allowed-directory /test/path

-```
-
-## Best Practices
-
-1. **Use Absolute Paths**: Always specify full paths to avoid ambiguity
-2. **Limit Directory Scope**: Only include necessary directories in allowed list
-3. **Regular Backups**: Important files should be backed up before modification
-4. **Test in Safe Environment**: Try operations in `/tmp` before production use
-5. **Monitor File Sizes**: Be aware of file size limits for read/write operations
