## π Top 3 MCP Server Issues - Resolution Status
|
| 12 |
+
|
| 13 |
+
### β
1. Protocol Version Format
|
| 14 |
+
**Issue:** MCP requires string-based version identifiers in YYYY-MM-DD format
|
| 15 |
+
**Status:** **RESOLVED**
|
| 16 |
+
**Implementation:**
|
| 17 |
+
- Protocol version: `2024-11-05` (current as of Dec 2025)
|
| 18 |
+
- Version format validated in `mcp_validation.py`
|
| 19 |
+
- Version declaration added to server initialization
|
| 20 |
+
|
| 21 |
+
**Validation:**
|
| 22 |
+
```bash
|
| 23 |
+
python mcp_validation.py
|
| 24 |
+
# β
Protocol version format valid: 2024-11-05
|
| 25 |
+
# β
Using current protocol version (2024-11-05)
|
| 26 |
+
```
|
| 27 |
+

|
| 36 |
+
- β
`@server.list_resources()` - Lists 3 resources
|
| 37 |
+
- β
`@server.read_resource()` - Reads resource content
|
| 38 |
+
|
| 39 |
+
**Available Tools:**
|
| 40 |
+
1. `analyze_project` - Detect over-engineering patterns
|
| 41 |
+
2. `get_pattern_advice` - Get detailed pattern advice
|
| 42 |
+
3. `estimate_costs` - Estimate technology costs
|
| 43 |
+

3. `archflow://knowledge/deep-dives` - Knowledge base
|
| 48 |
+
|
| 49 |
+
**Validation:**
|
| 50 |
+
```bash
|
| 51 |
+
python test_mcp_server.py

|
| 88 |
+
|
| 89 |
+
### Deployment Steps
|
| 90 |
+
|
| 91 |
+
#### 1. Local Testing
|
| 92 |
+
```bash
|
| 93 |
+
# Run validation suite
|
| 94 |
+
python mcp_validation.py
|
| 95 |
+
|
| 96 |
+
# Run manual tests
|
| 97 |
+
python test_mcp_server.py
|
| 98 |
+
|
| 99 |
+
# Test server startup
|
| 100 |
+
python mcp_server.py
|
| 101 |
+
```
|
| 102 |
+
|
| 103 |
+
#### 2. Configuration File
|
| 104 |
+
Create `mcp_config.json` for clients:
|
| 105 |
+
```json
|
| 106 |
+
{
|
| 107 |
+
"mcpServers": {
|
| 108 |
+
"archflow": {
|
| 109 |
+
"type": "stdio",
|
| 110 |
+
"command": "python",
|
| 111 |
+
"args": ["mcp_server.py"],
|
| 112 |
+
"cwd": ".",
|
| 113 |
+
"env": {}
|
| 114 |
+
}
|
| 115 |
+
}
|
| 116 |
+
}
|
| 117 |
+
```
|
| 118 |
+
|
| 119 |
+
#### 3. GitHub/Hugging Face Deployment
|
| 120 |
+
```bash
|
| 121 |
+
# Stage changes
|
| 122 |
+
git add mcp_server.py mcp_validation.py test_mcp_server.py MCP_DEPLOYMENT_GUIDE.md
|
| 123 |
+
|
| 124 |
+
# Commit
|
| 125 |
+
git commit -m "Add MCP server validation and deployment guide"
|
| 126 |
+
|
| 127 |
+
# Push to Hugging Face Space
|
| 128 |
+
git push
|
| 129 |
+
```
|
| 130 |
+
|
| 131 |
+
#### 4. Client Integration Testing
|
| 132 |
+
Test with MCP-compatible clients:
|
| 133 |
+
- **Claude Desktop** - Configure in `claude_desktop_config.json`
|
| 134 |
+
- **MCP Inspector** - Use for interactive testing
|
| 135 |
+

## π§ Troubleshooting
|
| 183 |
+
|
| 184 |
+
### Issue: "MCP SDK not found"
|
| 185 |
+
**Solution:**
|
| 186 |
+
```bash
|
| 187 |
+
pip install mcp
|
| 188 |
+
```
|
| 189 |
+
|
| 190 |
+
### Issue: "Cannot import from app.py"
|
| 191 |
+
**Solution:**
|
| 192 |
+
```bash
|
| 193 |
+
# Ensure you're in the correct directory
|
| 194 |
+
cd C:\Users\tuncl\Documents\ArchFlow-MCP-Hackathon\archflow-mcp-space
|
| 195 |
+
python test_mcp_server.py
|
| 196 |
+
```
|
| 197 |
+
|
| 198 |
+
### Issue: "Server not responding"
|
| 199 |
+
**Diagnosis:**
|
| 200 |
+
1. Check server logs (stderr)
|
| 201 |
+
2. Verify protocol version compatibility
|
| 202 |
+
3. Test with MCP Inspector
|
| 203 |
+
4. Check client configuration
|
| 204 |
+
|
| 205 |
+
**Common fixes:**
|
| 206 |
+
- Use absolute paths in client config
|
| 207 |
+
- Ensure Python is in PATH
|
| 208 |
+
- Verify MCP SDK version compatibility
|
