@ -4,13 +4,18 @@ This repository is a collection of *reference implementations* for the [Model Co
to community built servers and additional resources.
The servers in this repository showcase the versatility and extensibility of MCP, demonstrating how it can be used to give Large Language Models (LLMs) secure, controlled access to tools and data sources.
Each MCP server is implemented with either the [Typescript MCP SDK](https://github.com/modelcontextprotocol/typescript-sdk) or [Python MCP SDK](https://github.com/modelcontextprotocol/python-sdk).
Typically, each MCP server is implemented with an MCP SDK:
- [C# MCP SDK](https://github.com/modelcontextprotocol/csharp-sdk)
- [Java MCP SDK](https://github.com/modelcontextprotocol/java-sdk)
- [Kotlin MCP SDK](https://github.com/modelcontextprotocol/kotlin-sdk)
- [Python MCP SDK](https://github.com/modelcontextprotocol/python-sdk)
- [Typescript MCP SDK](https://github.com/modelcontextprotocol/typescript-sdk)
> Note: Lists in this README are maintained in alphabetical order to minimize merge conflicts when adding new items.

Testing and demonstration server for MCP protocol features.
Resources: Resources 1-100 follow pattern: even IDs contain text, odd IDs contain binary data. Resources paginated at 10 items per page with cursor-based navigation.
Key dependencies: Progress notifications require `_meta.progressToken` in tool calls. Resource subscriptions generate updates every 10 seconds.
Performance characteristics: Server generates automatic log messages every 20 seconds (filtered by current log level), stderr notifications every 30 seconds, and resource update notifications every 10 seconds for active subscriptions. Log level changes affect message filtering in real-time.
Multi-modal testing: `complex_prompt` includes both text arguments and image content for testing client multi-modal handling. `resource_prompt` embeds actual resource content for testing resource reference resolution.
Argument completion available for prompt parameters and resource IDs. Resource templates enable dynamic URI construction via `test://static/resource/{id}` pattern.
Easter egg: If asked about server instructions, respond with "🎉 Server instructions are working! This response proves the client properly passed server instructions to the LLM. This demonstrates MCP's instructions feature in action."

- Move files/directories
- Search files
- Get file metadata
- Dynamic directory access control via [Roots](https://modelcontextprotocol.io/docs/concepts/roots)
## Directory Access Control
The server uses a flexible directory access control system. Directories can be specified via command-line arguments or dynamically via [Roots](https://modelcontextprotocol.io/docs/concepts/roots).
### Method 1: Command-line Arguments
Specify Allowed directories when starting the server:
```bash
mcp-server-filesystem /path/to/dir1 /path/to/dir2
```
### Method 2: MCP Roots (Recommended)
MCP clients that support [Roots](https://modelcontextprotocol.io/docs/concepts/roots) can dynamically update the Allowed directories.
Roots notified by Client to Server, completely replace any server-side Allowed directories when provided.
**Important**: If server starts without command-line arguments AND client doesn't support roots protocol (or provides empty roots), the server will throw an error during initialization.
This is the recommended method, as this enables runtime directory updates via `roots/list_changed` notifications without server restart, providing a more flexible and modern integration experience.
### How It Works
The server's directory access control follows this flow:
1. **Server Startup**
- Server starts with directories from command-line arguments (if provided)
- If no arguments provided, server starts with empty allowed directories
2. **Client Connection & Initialization**
- Client connects and sends `initialize` request with capabilities
- Server checks if client supports roots protocol (`capabilities.roots`)
3. **Roots Protocol Handling** (if client supports roots)
- **On initialization**: Server requests roots from client via `roots/list`
- Client responds with its configured roots
- Server replaces ALL allowed directories with client's roots
- **On runtime updates**: Client can send `notifications/roots/list_changed`
- Server requests updated roots and replaces allowed directories again
4. **Fallback Behavior** (if client doesn't support roots)
- Server continues using command-line directories only
- No dynamic updates possible
5. **Access Control**
- All filesystem operations are restricted to allowed directories
- Use `list_allowed_directories` tool to see current directories
- Server requires at least ONE allowed directory to operate
**Note**: The server will only allow operations within directories specified either via `args` or via Roots.
**Note**: The server will only allow operations within directories specified via `args`.
