# MCP-This

> MCP Server that exposes CLI commands as tools using YAML files.

`mcp-this` is an MCP server that makes command-line tools available to Claude via the Model-Control-Protocol. The server reads YAML configuration files to define which commands should be exposed as MCP tools, along with their parameters and execution details. This allows Claude to execute CLI commands without requiring you to write any code.

## 📋 Features

- 🔧 **Dynamic Tool Creation**: Define CLI tools in YAML without writing code
- 🔄 **Command Execution**: Execute shell commands with parameter substitution
- 📁 **Working Directory Support**: Run commands in specific directories
- 🧩 **Toolset Organization**: Group related tools into logical toolsets
- 🤖 **Claude Integration**: Seamless integration with Claude Desktop

## 🚀 Installation

### Using pip

```bash
pip install mcp-this
```

### Using uv (recommended)

```bash
uv pip install mcp-this
```

## 🏁 Quick Start

1. Create a YAML configuration file:

### Using top-level tools

```yaml
tools:
  curl:
    description: "Make HTTP requests"
    execution:
      command: "curl <<arguments>>"
    parameters:
      arguments:
        description: "Complete curl arguments including options and URL"
        required: true
```

### Using toolsets

A toolset is a way to organize groups of tools. In the future, toolsets could, for example, share settings like allow/deny lists. Toolsets could also be used, for example, to enable/disable/search for sets of tools.

```yaml
toolsets:
  curl:
    description: "Transfer data from or to a server"
    tools:
      curl:
        description: "Make HTTP requests"
        execution:
          command: "curl <<arguments>>"
        parameters:
          arguments:
            description: "Complete curl arguments including options and URL"
            required: true
```

2. Run the MCP server:

```bash
# Using tools path
mcp-this --tools-path /path/to/your/config.yaml

# Using JSON string directly
mcp-this --tools '{"tools": {"echo": {"description": "Echo command", "execution": {"command": "echo <<message>>"}, "parameters": {"message": {"description": "Message to echo", "required": true}}}}}'

# Using environment variable
export MCP_THIS_CONFIG_PATH=/path/to/your/config.yaml
mcp-this
```

## 🛠️ Configuration Structure

The configuration YAML files can follow one of two structures:

### Toolsets Format (Original)

This format organizes tools into logical groups called toolsets:

```yaml
toolsets:
  toolset_name:
    description: "Toolset description"
    tools:
      tool_name:
        description: "Tool description"
        execution:
          command: "command template with <<parameter>> placeholders"
        parameters:
          parameter_name:
            description: "Parameter description"
            required: true/false
```

### Top-level Tools Format (New)

This simpler format defines tools directly at the top level:

```yaml
tools:
  tool_name:
    description: "Tool description"
    execution:
      command: "command template with <<parameter>> placeholders"
    parameters:
      parameter_name:
        description: "Parameter description"
        required: true/false
```

### Combined Format

You can also use both formats in the same file:

```yaml
tools:
  echo:
    description: "Simple echo command"
    execution:
      command: "echo <<message>>"
    parameters:
      message:
        description: "Message to echo"
        required: true

toolsets:
  file:
    description: "File operations"
    tools:
      cat:
        description: "Display file contents"
        execution:
          command: "cat <<file_path>>"
        parameters:
          file_path:
            description: "Path to file"
            required: true
```

### Parameter Substitution

Parameters in command templates use the `<<parameter>>` syntax:

```yaml
command: "find . -name \"<<pattern>>\" -type f | xargs wc -l"
```

When the tool is invoked, these placeholders are replaced with the actual parameter values.

## 🔌 Claude Desktop Integration

### Using uvx (Recommended)

The simplest way to configure Claude Desktop is to use `npx` and `uvx` to install and run `mcp-this` on demand:

```json
{
  "mcpServers": {
    "mcp-this": {
      "command": "uvx",
      "args": [
        "mcp-this",
        // "--tools", "{\"tools\": <json string defining tools>}"
        "--tools-path", "/path/to/your/config.yaml"
      ],
    }
  }
}
```

This approach:
- Automatically installs the latest version from PyPI when needed
- Doesn't require manual installation or updates
- Cleanly isolates dependencies

### Using a locally installed package

If you've installed `mcp-this` globally or in your environment:

```json
{
  "mcpServers": {
    "mcp-this": {
      "command": "mcp-this",
      "args": ["--tools-path", "/path/to/your/config.yaml"],
    }
  }
}
```

## 🧪 Development

### Setup Development Environment

```bash
# Clone the repository
git clone https://github.com/your-username/mcp-this.git
cd mcp-this

# Install dependencies
uv sync
```

### Development Commands

```bash
# Run linting
make linting

# Run tests
make tests

# Run the MCP server in development mode
make mcp_dev

# Build package

# Publish package to PyPI
make package-publish
```

### Testing with MCP Inspector

```bash
# Test with MCP Inspector using environment variable
MCP_THIS_CONFIG_PATH=./path/to/config.yaml uv run mcp dev ./src/mcp_this/mcp_server.py

# Test with MCP Inspector using command-line flags
uv run mcp dev -m mcp_this --tools-path ./path/to/config.yaml

# Test with MCP Inspector using JSON string
uv run mcp dev -m mcp_this --tools '{"tools": {"example": {"description": "Example tool", "execution": {"command": "echo Test"}}}}'
```

Essential Command-Line Tools for Coding Agents
Here are the key tools I'd recommend for a coding agent like Claude Desktop or Cursor, without implementing the actual commands:
1. File and Directory Navigation Tools

directory-tree: View project structure with customizable exclusions
find-files: Locate files by name, type, or pattern (e.g., all Python files)
count-files: Count files by type or pattern with statistics
recent-files: Find recently modified files in a project

2. Code Search and Analysis Tools

search-code: Find text patterns in files with context lines
count-occurrences: Count occurrences of patterns across codebase
search-functions: Find function definitions by name pattern
search-imports: Find import statements across project
find-dependencies: Identify project dependencies from files

3. Code Editing and Manipulation Tools

extract-section: Extract specific lines from a file
replace-text: Replace patterns in files with backup options
create-file: Create new files with specified content
modify-file: Modify existing files at specific locations
organize-imports: Sort and organize import statements

4. Version Control Tools

git-status: Show status of changes in repository
git-log: View commit history with filters
git-diff: Show changes between commits, branches, etc.
git-blame: Show who last modified each line of a file

5. Project Information Tools

find-todos: Locate TODOs and FIXMEs in codebase
list-definitions: Show class/function definitions in a file
show-docstrings: Extract documentation strings from code
analyze-complexity: Show complexity metrics for functions
check-style: Identify style issues in code

6. Language-Specific Tools

python-lint: Run linting tools on Python code
javascript-analyze: Analyze JavaScript code quality
typescript-check: Type-check TypeScript code
run-tests: Execute tests in specified files or directories

7. Content Extraction Tools

extract-html: Extract text content from HTML
fetch-webpage: Fetch and process web content
parse-json: Format and extract from JSON files
parse-yaml: Parse and extract from YAML files

8. Project Management Tools

project-stats: Display statistics about project size/structure
find-duplicates: Locate duplicate code or files
extract-api-docs: Generate API documentation from comments
analyze-imports: Show dependency graph for modules

These tools would give a coding agent comprehensive capabilities to navigate, understand, analyze, and modify code, enabling it to provide more intelligent assistance. The focus is on tools that help with code comprehension, search, and targeted modifications rather than running arbitrary commands.
