# MCP Integration Architecture

This document describes how the MCP Standards Server integrates with the Model Context Protocol to provide standards as accessible tools for LLMs.

## Overview

The MCP integration layer exposes standards functionality through standardized tool interfaces, enabling seamless integration with LLM applications.

## Core MCP Tools

### 1. get_applicable_standards
Retrieves relevant standards based on project context.

```json
{
  "name": "get_applicable_standards",
  "parameters": {
    "project_type": "string",
    "frameworks": ["array", "of", "strings"],
    "requirements": ["array", "of", "requirements"]
  }
}
```

### 2. validate_against_standard
Validates code against specific standards.

```json
{
  "name": "validate_against_standard",
  "parameters": {
    "code_path": "string",
    "standard_id": "string",
    "options": {}
  }
}
```

### 3. suggest_improvements
Provides improvement recommendations based on standards.

## Protocol Implementation

                                    ┌──────────────┐
                                    │   Handlers   │
                                    └──────────────┘
```

## Security Considerations

- Authentication via API keys
- Rate limiting per client
- Input validation and sanitization

## Error Handling

- Graceful degradation
- Detailed error messages
- Retry mechanisms

## Implementation

See [src/core/mcp/](../../../src/core/mcp/) for the MCP server implementation.
