**DesktopCommanderMCP exposes file-system, process-control, and data-analysis capabilities via a JSON-RPC-like HTTP API, allowing any HTTP-capable tool to authenticate via Bearer tokens and invoke methods such as `fs.readFile`, `process.exec`, or custom plugin methods.**

DesktopCommanderMCP, available at `wonderwhy-er/DesktopCommanderMCP`, operates as a standalone Model-Context-Protocol (MCP) server. Because it communicates over standard HTTP rather than requiring language-specific bindings, you can integrate it with automation scripts, CI/CD pipelines, or any programming environment that supports HTTP clients.

## Understanding the MCP Endpoint and Protocol Structure

The server listens for commands at `http://localhost:<port>/mcp` (default port `8080`). According to the [`README.md`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/README.md) in the repository, all interactions follow a JSON-RPC-like format where requests contain `method`, `params`, and an optional `id` for request-response correlation.

The endpoint accepts POST requests with this payload structure:

```json
{
  "jsonrpc": "2.0",
  "id": 123,
  "method": "fs.readFile",
  "params": {
    "path": "/home/user/file.txt"
  }
}

```

### Supported MCP Methods

The server exposes a comprehensive set of capabilities through standardized method names. Available methods include `fs.readFile` for file access, `process.exec` for command execution, `excel.read` for spreadsheet processing, `pdf.create` for document generation, and `config.get` for configuration retrieval.

## Authentication and Security Implementation

DesktopCommanderMCP implements the standard MCP security model using Bearer token authentication. Before invoking protected methods, you must generate a token using the `auth.generateToken` method or configure one in [`server.json`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/server.json) or [`server.yaml`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/server.yaml).

Include the token in your request headers:

```

Authorization: Bearer <token>

```

This security layer ensures that only authorized tools can execute potentially dangerous operations like shell command execution or file system modifications.

## Calling DesktopCommanderMCP Methods from Your Tools

You can invoke MCP methods from any HTTP client. The repository demonstrates integration patterns for JavaScript, Python, and shell environments.

### JavaScript and Node.js Integration

Using **Axios**, create a reusable helper to call MCP methods:

```javascript
const axios = require('axios');

async function callMcp(method, params = {}) {
  const resp = await axios.post(
    'http://localhost:8080/mcp',
    { jsonrpc: '2.0', id: Date.now(), method, params },
    { headers: { Authorization: 'Bearer YOUR_TOKEN' } }
  );
  return resp.data.result;
}

// Example: Read file with pagination
(async () => {
  const content = await callMcp('fs.readFile', {
    path: '/home/user/project/README.md',
    offset: -200,
    length: 200
  });
  console.log('Tail of README:', content);
})();

```

### Python Integration

Using the **requests** library:

```python
import requests, time

MCP_URL = "http://localhost:8080/mcp"
HEADERS = {"Authorization": "Bearer YOUR_TOKEN"}

def call_mcp(method, params=None):
    payload = {
        "jsonrpc": "2.0",
        "id": int(time.time()*1000),
        "method": method,
        "params": params or {}
    }
    r = requests.post(MCP_URL, headers=HEADERS, json=payload)
    r.raise_for_status()
    return r.json()["result"]

# Example: Execute shell command with streaming

result = call_mcp("process.exec", {"command": "ls -R .", "stream": True})
print(result["output"])

```

### Shell and cURL Integration

For command-line tools and bash scripts:

```bash
TOKEN=$(cat ~/.desktop-commander/token)
curl -X POST http://localhost:8080/mcp \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"excel.read","params":{"path":"data.xlsx","sheet":"Sheet1"}}' | jq .

```

## Handling Streaming and Paginated Responses

For long-running commands or large file reads, DesktopCommanderMCP supports output pagination through `offset` and `length` parameters, and streaming via the `process.stream` method. This prevents overloading the model context when processing large datasets.

Use **negative offsets** to read from the end of files (tail behavior), and set `stream: true` in `process.exec` calls to receive incremental output rather than buffering everything in memory.

## Extending Capabilities with Custom Plugins

The repository supports custom MCP plugins defined in [`plugin.yaml`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/plugin.yaml). You can extend DesktopCommanderMCP by implementing new methods that external tools invoke just like built-in methods.

To add a custom plugin:

1. Create a JavaScript module (e.g., [`my-plugin.js`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/my-plugin.js)) exporting a handler function
2. Register it in [`plugin.yaml`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/plugin.yaml):

```yaml
plugins:
  - name: myTool
    module: ./my-plugin.js
    methods:
      - myTool.doSomething

```

3. Restart the server to load the plugin

External tools can now call `myTool.doSomething` through the standard HTTP MCP endpoint. The repository includes [`scripts/ripgrep-wrapper.js`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/scripts/ripgrep-wrapper.js) as a reference implementation demonstrating how utility scripts integrate with the MCP server architecture.

## Key Configuration Files Reference

## Frequently Asked Questions

### How do I authenticate requests to DesktopCommanderMCP?

Generate a Bearer token using the `auth.generateToken` method or through the server configuration files ([`server.json`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/server.json) or [`server.yaml`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/server.yaml)). Include this token in the `Authorization: Bearer <token>` header for every HTTP request to the `/mcp` endpoint. This security model ensures only authorized clients can execute file system or process operations.

### What programming languages can I use to integrate with DesktopCommanderMCP?

Any language capable of making HTTP POST requests can integrate with DesktopCommanderMCP. The repository provides examples for **JavaScript/Node.js** using Axios, **Python** using the requests library, and **shell scripts** using cURL. The JSON-RPC protocol is language-agnostic, so you can implement clients in Go, Rust, Ruby, or any other language with HTTP support.

### How do I handle large file reads or long-running commands?

Use the pagination parameters (`offset` and `length`) available in methods like `fs.readFile` to read specific portions of files. For long-running shell commands, set `stream: true` when calling `process.exec` or use the dedicated `process.stream` method. This returns data incrementally and prevents memory issues when processing large outputs.

### Can I add custom functionality that my other tools can call?

Yes, DesktopCommanderMCP supports custom plugins defined in [`plugin.yaml`](https://github.com/wonderwhy-er/DesktopCommanderMCP/blob/main/plugin.yaml). Create a JavaScript module implementing your custom logic, register it with a unique method name (e.g., `myTool.doSomething`), and restart the server. External tools can then invoke your custom method through the standard HTTP MCP endpoint exactly like built-in methods.
