## MCP Inspector Compatibility
The server is fully compatible with [MCP Inspector](https://github.com/modelcontextprotocol/inspector) for debugging and testing MCP tools:
### Schema Format
- **Wrapped Parameters**: Tool schemas use the MCP Inspector expected format with named input wrappers (e.g., `GetRfcInput`, `SearchRfcsInput`)
- **Backward Compatibility**: Still supports direct parameter format for existing clients
- **Auto-Detection**: Automatically detects and handles both parameter formats
- **Comprehensive Schemas**: All 9 tools have detailed JSON Schema definitions with proper validation
- **Parameter Descriptions**: Rich parameter descriptions and constraints for better UX
### Protocol Compliance
- **JSON-RPC 2.0**: Full compliance with JSON-RPC 2.0 specification
- **MCP Notifications**: Proper handling of `notifications/initialized` and other standard notifications
- **ID Consistency**: Maintains ID type consistency between requests and responses
- **Error Handling**: Proper error response format with appropriate error codes
### Testing with MCP Inspector
```bash
# Start the server in HTTP mode
python3 standard_finder.py --http --port 3000
# Connect MCP Inspector to http://localhost:3000/mcp
# All tools will appear with proper parameter schemas and validation
# Test both direct and wrapped parameter formats
```
### Debugging Features
- **Enhanced Logging**: Detailed logging for initialize phase and all MCP operations
- **Request/Response Tracking**: Complete visibility into MCP protocol exchanges
- **Validation Logging**: Detailed validation of requests and responses
- **Error Diagnostics**: Comprehensive error reporting with stack traces
## Transport Modes
### Stdio Mode (Default)
- ✅ **MCP Standard** - The official MCP transport protocol
- ✅ **Process-based** - Client spawns server as subprocess
- ✅ **Reliable** - Direct process communication
- ✅ **Secure** - No network exposure
- ✅ **Q CLI Compatible** - Works perfectly with MCP clients
### HTTP Mode
- 🌐 **Network-based** - Server runs as HTTP service
- 🔧 **Development/Testing** - Useful for debugging
- 🌍 **Web Integration** - CORS enabled for browser access
- 🔒 **Network Security** - Requires additional security considerations
## Quick Start Examples
### Using with MCP Client
Once configured, you can use the tools in any MCP-compatible client:
```python
# Get RFC 2616 (HTTP/1.1)
await mcp.call_tool('get_rfc', {'number': '2616', 'format': 'metadata'})
# Search for HTTP-related RFCs
await mcp.call_tool('search_rfcs', {'query': 'HTTP', 'limit': 5})
# Get latest HTTP/2 Internet Draft
await mcp.call_tool('get_internet_draft', {'name': 'draft-ietf-httpbis-http2'})
```
# Search for WebSocket 草案
await mcp.call_tool('search_internet_drafts', {'query': 'websocket'})
# 获取 OAuth 工作组的所有文档
await mcp.call_tool('get_working_group_documents', {
'working_group': 'oauth',
'include_rfcs': True,
'include_drafts': True,
'limit': 20
})
# 仅从 TLS 工作组获取 RFC
await mcp.call_tool('get_working_group_documents', {
'working_group': 'tls',
'include_rfcs': True,
'include_drafts': False,
'limit': 10
})
# 获取 OpenID Connect Core 规范
await mcp.call_tool('get_openid_spec', {
'name': 'openid-connect-core',
'format': 'metadata'
})
# 搜索 OAuth 规范
await mcp.call_tool('search_openid_specs', {
'query': 'oauth',
'limit': 5
})
```
### Using Resources
```python
# Access via resource URIs
await mcp.read_resource('rfc://2616')
await mcp.read_resource('draft://draft-ietf-httpbis-http2')
await mcp.read_resource('rfc://search/HTTP')
# Working group resources
await mcp.read_resource('wg://httpbis') # All documents
await mcp.read_resource('wg://oauth/rfcs') # Only RFCs
await mcp.read_resource('wg://tls/drafts') # Only drafts
```

## Troubleshooting
### Common Issues
#### MCP Inspector Connection Issues
```bash
# Ensure server is running in HTTP mode
python3 standard_finder.py --http --port 3000
# Check server is responding
curl http://localhost:3000/health
# Verify MCP endpoint
curl -X POST http://localhost:3000/mcp \
-H "Content-Type: application/json" \
-d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2024-11-05","capabilities":{},"clientInfo":{"name":"test","version":"1.0"}}}'
```
#### STDIO Mode Issues
- **Large Response Truncation**: Responses over 200KB are automatically truncated in STDIO mode
- **Character Encoding**: Special characters are sanitized for STDIO compatibility
- **Connection Drops**: Check logs for transport closure issues
#### Logging and Debugging
```bash
# Enable debug logging
python3 standard_finder.py --log-level DEBUG
# Check log files
ls -la /tmp/rfc_server/
# Monitor real-time logs
tail -f /tmp/rfc_server/rfc_server_*.log
```
#### Tool Parameter Issues
- **MCP Inspector Format**: Use wrapped parameters like `{"GetRfcInput": {"number": "2616"}}`
- **Direct Format**: Use direct parameters like `{"number": "2616", "format": "metadata"}`
- **Auto-Detection**: Server automatically detects and handles both formats
### Performance Optimization
- **Caching**: Responses are cached in memory for repeated requests
- **Format Selection**: Use `"metadata"` format for faster responses when full content isn't needed
- **Limit Parameters**: Use appropriate limits for search operations to avoid timeouts
## Implementation Details
The server implements three main components:
1. **RFC Service**: Handles fetching, parsing, and extracting data from RFCs with enhanced title parsing
2. **Internet Draft Service**: Handles fetching, parsing, and extracting data from Internet Drafts with working group support
3. **MCP Server**: Implements the MCP protocol and exposes tools and resources with both stdio and HTTP transport
Standards Finder uses only the Python standard library, with TXT format parsing for maximum compatibility. The Internet Draft service integrates with the IETF Datatracker API for enhanced search capabilities and working group document retrieval.
### Key Features
#### Smart Version Handling
The Internet Draft service automatically detects whether you're requesting a specific version or the latest:
- `draft-ietf-httpbis-http2-17` → Fetches version 17 specifically
- `draft-ietf-httpbis-http2` → Automatically fetches the latest available version
#### Working Group Integration
- **Complete Document Retrieval** - Get all RFCs and Internet Drafts for any IETF working group
- **Real-time Data** - Uses live IETF Datatracker API for up-to-date information
- **Smart Filtering** - Automatically excludes expired, withdrawn, or replaced documents
- **Flexible Options** - Choose document types and set limits per your needs
#### Robust Error Handling
- Network timeouts and failures are handled gracefully
- Invalid RFC/draft numbers return informative error messages
- Fallback mechanisms ensure maximum compatibility
- Comprehensive logging for debugging and monitoring
#### Performance Optimized
- In-memory caching reduces repeated network requests
- Concurrent request handling for better throughput
- Efficient parsing of both HTML and plain text formats
- HTTP mode supports multiple simultaneous connections
- Enhanced RFC title extraction for better metadata
### Data Sources
- **RFCs**: Official IETF RFC repository (rfc-editor.org)
- **Internet Drafts**: IETF Datatracker (datatracker.ietf.org)
- **Working Groups**: IETF Datatracker API (datatracker.ietf.org/api)
- **Search**: IETF Datatracker API with web scraping fallback
### Popular Working Groups Supported
- **httpbis** - HTTP protocol specifications
- **oauth** - OAuth authentication and authorization
- **tls** - Transport Layer Security
- **quic** - QUIC transport protocol
- **dnsop** - DNS operations
- **jose** - JSON Object Signing and Encryption
- **ietf** - General IETF documents
- And many more...
