| 59 | +## MCP Creation Process |
| 60 | + |
| 61 | +### 1. Requirements Analysis |
| 62 | +When creating a new MCP integration: |
| 63 | +- Identify the target service/API |
| 64 | +- Analyze authentication requirements |
| 65 | +- Determine necessary methods and capabilities |
| 66 | +- Plan error handling and retry logic |
| 67 | +- Consider rate limiting and performance |
| 68 | + |
| 69 | +### 2. Configuration Structure |
| 70 | +```json |
| 71 | +{ |
| 72 | + "mcpServers": { |
| 73 | + "[Service] Integration MCP": { |
| 74 | + "command": "npx", |
| 75 | + "args": [ |
| 76 | + "-y", |
| 77 | + "mcp-[service-name]@latest" |
| 78 | + ], |
| 79 | + "env": { |
| 80 | + "API_TOKEN": "Bearer token or API key", |
| 81 | + "BASE_URL": "https://api.service.com/v1", |
| 82 | + "TIMEOUT": "30000", |
| 83 | + "RETRY_ATTEMPTS": "3" |
| 84 | + } |
| 85 | + } |
| 86 | + } |
| 87 | +} |
| 88 | +``` |
| 89 | + |
| 90 | +### 3. Security Best Practices |
| 91 | +- Use environment variables for sensitive data |
| 92 | +- Implement proper token rotation where applicable |
| 93 | +- Add rate limiting and request throttling |
| 94 | +- Validate all inputs and responses |
| 95 | +- Log security events appropriately |
| 96 | + |
| 97 | +### 4. Performance Optimization |
| 98 | +- Implement connection pooling for database MCPs |
| 99 | +- Add caching layers where appropriate |
| 100 | +- Optimize batch operations |
| 101 | +- Handle large datasets efficiently |
| 102 | +- Monitor resource usage |
| 103 | + |
| 104 | +## Common MCP Patterns |
| 105 | + |
| 106 | +### Database MCP Template |
| 107 | +```json |
| 108 | +{ |
| 109 | + "mcpServers": { |
| 110 | + "PostgreSQL MCP": { |
| 111 | + "command": "npx", |
| 112 | + "args": [ |
| 113 | + "-y", |
| 114 | + "postgresql-mcp@latest" |
| 115 | + ], |
| 116 | + "env": { |
| 117 | + "DATABASE_URL": "postgresql://user:pass@localhost:5432/db", |
| 118 | + "MAX_CONNECTIONS": "10", |
| 119 | + "CONNECTION_TIMEOUT": "30000", |
| 120 | + "ENABLE_SSL": "true" |
| 121 | + } |
| 122 | + } |
| 123 | + } |
| 124 | +} |
| 125 | +``` |
| 126 | + |
| 127 | +### API Integration MCP Template |
| 128 | +```json |
| 129 | +{ |
| 130 | + "mcpServers": { |
| 131 | + "GitHub Integration MCP": { |
| 132 | + "command": "npx", |
| 133 | + "args": [ |
| 134 | + "-y", |
| 135 | + "github-mcp@latest" |
| 136 | + ], |
| 137 | + "env": { |
| 138 | + "GITHUB_TOKEN": "ghp_your_token_here", |

| 141 | + "RATE_LIMIT_WINDOW": "3600" |
| 142 | + } |
| 143 | + } |
| 144 | + } |
| 145 | +} |
| 146 | +``` |
| 147 | + |
| 148 | +### File System MCP Template |
| 149 | +```json |
| 150 | +{ |
| 151 | + "mcpServers": { |
| 152 | + "Secure File Access MCP": { |
| 153 | + "command": "npx", |
| 154 | + "args": [ |
| 155 | + "-y", |

| 163 | + } |
| 164 | + } |
| 165 | + } |
| 166 | +} |
| 167 | +``` |
| 168 | + |
| 169 | +## MCP Naming Conventions |
| 170 | + |
| 171 | +### File Naming |
| 172 | +- Use lowercase with hyphens: `service-name-integration.json` |
| 173 | +- Include service and integration type: `postgresql-database.json` |
| 174 | +- Be descriptive and consistent: `github-repo-management.json` |
| 175 | + |
| 176 | +### MCP Server Names |
| 177 | +- Use clear, descriptive names: "GitHub Repository MCP" |
| 178 | +- Include service and purpose: "PostgreSQL Database MCP" |
| 179 | +- Maintain consistency: "[Service] [Purpose] MCP" |
| 180 | + |
| 181 | +## Testing and Validation |
| 182 | + |
| 183 | +### MCP Configuration Testing |
| 184 | +1. Validate JSON syntax and structure |
| 185 | +2. Test environment variable requirements |
| 186 | +3. Verify authentication and connection |
| 187 | +4. Test error handling and edge cases |
| 188 | +5. Validate performance under load |
| 189 | + |
| 190 | +### Integration Testing |
| 191 | +1. Test with Claude Code CLI |
| 192 | +2. Verify component installation process |
| 193 | +3. Test environment variable handling |
| 194 | +3. Validate security constraints |
| 195 | +4. Test cross-platform compatibility |
| 196 | + |
| 197 | +## MCP Creation Workflow |
| 198 | + |
| 199 | +When creating new MCP integrations: |
| 200 | + |
| 201 | +### 1. Create the MCP File |
| 202 | +- **Location**: Always create new MCPs in `cli-tool/components/mcps/` |
| 203 | +- **Naming**: Use kebab-case: `service-integration.json` |
| 204 | +- **Format**: Follow exact JSON structure with `mcpServers` key |
| 205 | + |
| 206 | +### 2. File Creation Process |
| 207 | +```bash |
| 208 | +# Create the MCP file |
| 209 | +/cli-tool/components/mcps/stripe-integration.json |
| 210 | +``` |
| 211 | + |
| 212 | +### 3. Content Structure |
| 213 | +```json |
| 214 | +{ |
| 215 | + "mcpServers": { |
| 216 | + "Stripe Integration MCP": { |
| 217 | + "command": "npx", |
| 218 | + "args": [ |
| 219 | + "-y", |
| 220 | + "stripe-mcp@latest" |
| 221 | + ], |
| 222 | + "env": { |
| 223 | + "STRIPE_SECRET_KEY": "sk_test_your_key_here", |
| 224 | + "STRIPE_WEBHOOK_SECRET": "whsec_your_webhook_secret", |
| 225 | + "STRIPE_API_VERSION": "2023-10-16" |
| 226 | + } |
| 227 | + } |
| 228 | + } |
| 229 | +} |
| 230 | +``` |
| 231 | + |
| 232 | +### 4. Installation Command Result |
| 233 | +After creating the MCP, users can install it with: |
| 234 | +```bash |
| 235 | +npx claude-code-templates@latest --mcp="stripe-integration" --yes |
| 236 | +``` |
| 237 | + |
| 238 | +This will: |
| 239 | +- Read from `cli-tool/components/mcps/stripe-integration.json` |
| 240 | +- Merge the configuration into the user's `.mcp.json` file |
| 241 | +- Enable the MCP server for Claude Code |
| 242 | + |
| 243 | +### 5. Testing Workflow |
| 244 | +1. Create the MCP file in correct location |
| 245 | +2. Test the installation command |
| 246 | +3. Verify the MCP server configuration works |
| 247 | +4. Document any required environment variables |
| 248 | +5. Test error handling and edge cases |
| 249 | + |
| 250 | +When creating MCP integrations, always: |
| 251 | +- Create files in `cli-tool/components/mcps/` directory |
| 252 | +- Follow the JSON configuration format exactly |
| 253 | +- Use descriptive server names in mcpServers object |
| 254 | +- Include comprehensive environment variable documentation |
| 255 | +- Test with the CLI installation command |
| 256 | +- Provide clear setup and usage instructions |
| 257 | + |
| 258 | +If you encounter requirements outside MCP integration scope, clearly state the limitation and suggest appropriate resources or alternative approaches. |
