The package successfully generated a working MCP server with 32 tools, 2 resources, and 2 prompts. + +## What Was Accomplished + +### ✅ Successfully Created +- **YAML Configuration**: Created a comprehensive configuration file (`shell_operations_server.yml`) with: + - 32 shell operation tools (file management, system info, text processing, etc.) + - 2 resources (system status and file information) + - 2 prompts (file analysis and system diagnosis) + - 4 reusable argument definitions +- **Generated MCP Server**: Successfully generated a working FastMCP server (`shell_operations_server.py`) +- **Requirements File**: Generated `requirements.txt` with necessary dependencies +- **Documentation**: Generated `README.md` with usage instructions + +### ✅ Successfully Tested +- All 32 tools are functional and execute shell commands correctly +- Template rendering works properly with Jinja2 +- Argument validation and type checking works +- Resources generate dynamic content from shell commands +- Prompts render templates with variable substitution +- The server starts and runs without errors + +## Difficulties Encountered + +### 1. **CLI Installation and Execution Issues** + +**Problem**: The package CLI was difficult to run due to module import issues. + +**Details**: +- `python3 -m shellmcp validate` failed with "No module named shellmcp.__main__" +- `shellmcp` command was not available after installation +- Had to use `PYTHONPATH=/workspace python3 -m shellmcp.cli` to run commands + +**Impact**: Made initial validation and generation more cumbersome than expected. + +**Workaround**: Used direct Python imports and created custom scripts to bypass CLI issues. + +### 2. **Pydantic Model Validation Issue** + +**Problem**: Referenced arguments required empty `help` fields, which was counterintuitive. + +**Details**: +- When using `ref: path_arg` in tool arguments, the `help` field was still required +- This caused 25 validation errors during configuration parsing +- The error message was: `Field required [type=missing, input_value={'name': 'path', 'ref': 'path_arg'}]` + +**Impact**: Required manual fixing of all referenced arguments in the YAML file. + +**Workaround**: Created a script to automatically add empty `help: ""` fields to all referenced arguments. + +**Root Cause**: The Pydantic model requires `help` field even when using references, but the resolution logic should handle this automatically. + +### 3. **Missing Dependencies** + +**Problem**: The package didn't install all required dependencies automatically. + +**Details**: +- Had to manually install `fire`, `questionary`, `pydantic`, `pyyaml`, `jinja2` +- The `pyproject.toml` lists these as dependencies but they weren't installed with the package + +**Impact**: Required additional manual installation steps. + +### 4. **CLI Output Issues** + +**Problem**: CLI commands ran but didn't show expected output. + +**Details**: +- `shellmcp validate --verbose` ran without showing validation results +- `shellmcp generate --verbose` ran without showing generation progress + +**Impact**: Made it difficult to understand what the CLI was doing. + +### 5. **Testing MCP Tools** + +**Problem**: Generated MCP tools were not directly callable. + +**Details**: +- Tools are decorated with `@mcp.tool()` making them `FunctionTool` objects +- Direct calling failed with "FunctionTool object is not callable" +- Had to access underlying functions via `.fn` attribute + +**Impact**: Required understanding of FastMCP internals to test the generated tools. + +**Workaround**: Used `tool.fn()` to access and test the underlying functions. + +## Positive Aspects + +### 1. **Comprehensive Template System** +- Jinja2 templates work excellently for command generation +- Template validation catches syntax errors +- Variable substitution works perfectly + +### 2. **Flexible Configuration** +- Reusable argument definitions reduce duplication +- Support for different argument types (string, number, boolean, array) +- Validation patterns and choices work well + +### 3. **Rich Feature Set** +- Supports tools, resources, and prompts +- Environment variable configuration +- Help command integration +- Multiple content sources (cmd, file, text, template) + +### 4. **Generated Code Quality** +- Clean, well-structured generated Python code +- Proper error handling and timeouts +- Good documentation in generated functions + +### 5. **Validation System** +- Comprehensive validation of YAML configuration +- Template syntax validation +- Argument consistency checking + +## Recommendations for Improvement + +### 1. **Fix CLI Issues** +- Add proper `__main__.py` to enable `python -m shellmcp` execution +- Ensure CLI commands show appropriate output +- Fix dependency installation issues + +### 2. **Improve Pydantic Models** +- Make `help` field optional when using `ref` +- Add better error messages for validation failures +- Consider using model validators to handle reference resolution + +### 3. **Enhance Documentation** +- Add more examples in the README +- Document the CLI usage more clearly +- Provide troubleshooting guide + +### 4. **Add Testing Utilities** +- Provide built-in testing functions for generated servers +- Add validation for generated code +- Include example test scripts + +### 5. **Improve Error Messages** +- More descriptive error messages for common issues +- Better guidance on fixing validation errors +- Clearer indication of what went wrong + +## Overall Assessment + +**Rating: 7/10** + +The ShellMCP package successfully accomplishes its core goal of generating MCP servers from YAML configurations. The generated server works perfectly and includes all expected functionality. However, the development experience could be significantly improved by addressing the CLI issues, dependency management, and validation problems. + +### Strengths: +- ✅ Core functionality works excellently +- ✅ Generated code is high quality +- ✅ Comprehensive feature set +- ✅ Good template system +- ✅ Effective validation + +### Areas for Improvement: +- ❌ CLI usability issues +- ❌ Dependency management problems +- ❌ Pydantic model validation quirks +- ❌ Limited error messaging +- ❌ Testing complexity + +## Conclusion + +Despite the difficulties encountered, the ShellMCP package successfully generated a fully functional MCP server for common shell operations. The package shows great potential but needs refinement in its development experience and tooling. With the identified issues addressed, this would be an excellent tool for creating MCP servers from shell commands. + +The generated server includes 32 useful shell operations covering file management, system monitoring, text processing, and more, making it a valuable addition to any MCP ecosystem. \ No newline at end of file diff --git a/requirements.txt b/requirements.txt new file mode 100644 index 0000000..4b34ceb --- /dev/null +++ b/requirements.txt @@ -0,0 +1,3 @@ +fastmcp>=0.1.0 +jinja2>=3.0.0 +pyyaml>=6.0 \ No newline at end of file diff --git a/shell_operations_server.py b/shell_operations_server.py new file mode 100644 index 0000000..7324fdb --- /dev/null +++ b/shell_operations_server.py @@ -0,0 +1,1287 @@ +"""Generated FastMCP server from YAML configuration.""" + +import os +import subprocess +import tempfile +import shlex +from datetime import datetime +from typing import Any, Dict, List, Optional +from fastmcp import FastMCP +from jinja2 import Template, Environment + +def execute_command(cmd: str, env_vars: Optional[Dict[str, str]] = None) -> Dict[str, Any]: + """Execute a shell command and return the result.""" + try: + # Prepare environment + env = os.environ.copy() + if env_vars: + env.update(env_vars) + + # Execute command + result = subprocess.run( + cmd, + shell=True, + capture_output=True, + text=True, + env=env, + timeout=300 # 5 minute timeout + ) + + return { + "success": result.returncode == 0, + "stdout": result.stdout, + "stderr": result.stderr, + "returncode": result.returncode + } + except subprocess.TimeoutExpired: + return { + "success": False, + "stdout": "", + "stderr": "Command timed out after 5 minutes", + "returncode": -1 + } + except Exception as e: + return { + "success": False, + "stdout": "", + "stderr": str(e), + "returncode": -1 + } + +def render_template(template_str: str, **kwargs) -> str: + """Render Jinja2 template with provided variables.""" + try: + # Add built-in functions + context = { + 'now': datetime.now, + **kwargs + } + + template = Template(template_str) + return template.render(**context) + except Exception as e: + raise ValueError(f"Template rendering error: {e}") + +# Initialize FastMCP server +mcp = FastMCP(name="shell-operations") + +# Server configuration +SERVER_NAME = "shell-operations" +SERVER_DESC = "Common shell operations for file management, system info, and text processing" +SERVER_VERSION = "1.0.0" + + +@mcp.tool() +def list_files(path: str = ".") -> Dict[str, Any]: + """ + List files and directories with detailed information + + Parameters: + -
