| 1 | +# Testing Output Schema with curl |
| 2 | + |
| 3 | +Quick reference for testing the output_schema implementation using curl. |
| 4 | + |
| 5 | +## Setup |
| 6 | + |
| 7 | +First, generate a JWT token and export it: |
| 8 | + |
| 9 | +```bash |
| 10 | +export TOKEN= $(python3 -m mcpgateway.utils.create_jwt_token --username [email protected] --exp 0 --secret changeme123) |
| 11 | +``` |
| 12 | + |
| 13 | +Or use an existing token: |
| 14 | +```bash |
| 15 | +export TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZSI6ImFkbWluQGV4YW1wbGUuY29tIiwiaWF0IjoxNzYwNjQzNTU1LCJpc3MiOiJtY3BnYXRld2F5IiwiYXVkIjoibWNwZ2F0ZXdheS1hcGkiLCJzdWIiOiJhZG1pbkBleGFtcGxlLmNvbSJ9.4qSaXA5D3jEEJNh9VTDvPbQP7CflF9wU_x9EAoXVB8I" |
| 16 | +``` |
| 17 | + |
| 18 | +## Quick Test Commands |
| 19 | + |
| 20 | +### 1. List All Tools (Check for outputSchema field) |
| 21 | + |
| 22 | +```bash |
| 23 | +curl -s -H "Authorization: Bearer $TOKEN" \ |
| 24 | + http://localhost:4444/tools | jq '.' |
| 25 | +``` |
| 26 | + |
| 27 | +### 2. Find a Specific Tool (e.g., add_numbers) |
| 28 | + |
| 29 | +```bash |
| 30 | +curl -s -H "Authorization: Bearer $TOKEN" \ |
| 31 | + http://localhost:4444/tools | jq '.[] | select(.name == "add_numbers")' |
| 32 | +``` |
| 33 | + |
| 34 | +### 3. Check outputSchema Field Specifically |
| 35 | + |
| 36 | +```bash |
| 37 | +curl -s -H "Authorization: Bearer $TOKEN" \ |
| 38 | + http://localhost:4444/tools | \ |
| 39 | + jq '.[] | select(.name == "add_numbers") | {name, inputSchema, outputSchema}' |
| 40 | +``` |
| 41 | + |
| 42 | +**Expected Output**: |
| 43 | +```json |
| 44 | +{ |
| 45 | + "name": "add_numbers", |
| 46 | + "inputSchema": { |
| 47 | + "properties": { |

| 99 | +```bash |
| 100 | +curl -s -H "Authorization: Bearer $TOKEN" \ |
| 101 | + http://localhost:4444/tools | \ |
| 102 | + jq '.[] | select(.name | contains("_numbers") or contains("create_user") or contains("validate_email") or . == "echo") | {name, has_output_schema: (.outputSchema != null)}' |
| 103 | +``` |
| 104 | + |
| 105 | +**Expected Output**: |

| 232 | + |
| 233 | +```bash |
| 234 | +sqlite3 mcp.db "SELECT name, output_schema FROM tools WHERE name='add_numbers';" |
| 235 | +``` |
| 236 | + |
| 237 | +## Complete Test Script |
| 238 | + |
| 239 | +Save this as `test-output-schema.sh`: |

| 292 | + |
| 293 | +### Token expired or invalid |
| 294 | +```bash |

| 296 | +export TOKEN= $(python3 -m mcpgateway.utils.create_jwt_token --username [email protected] --exp 0 --secret changeme123 2>/dev/null | head -1) |
| 297 | +``` |
| 298 | + |
| 299 | +### Gateway not running |
| 300 | +```bash |
| 301 | +# Check if gateway is running |
| 302 | +curl -s http://localhost:4444/health |
| 303 | + |
| 304 | +# Start gateway |
| 305 | +make dev |
| 306 | +``` |
| 307 | + |
| 308 | +### Tools not showing up |
| 309 | +```bash |
| 310 | +# Check gateway registration |
| 311 | +curl -s -H "Authorization: Bearer $TOKEN" \ |
| 312 | + http://localhost:4444/gateways | jq '.' |
| 313 | + |
| 314 | +# Check if test server is running |
| 315 | +ps aux | grep output_schema_test_server |
| 316 | +``` |
| 317 | + |
| 318 | +### outputSchema is null when it shouldn't be |
| 319 | +```bash |
| 320 | +# Check database migration |
| 321 | +sqlite3 mcp.db "SELECT sql FROM sqlite_master WHERE name='tools';" | grep output_schema |
| 322 | + |
| 323 | +# Re-discover tools from gateway |
| 324 | +curl -X POST -H "Authorization: Bearer $TOKEN" \ |
| 325 | + http://localhost:4444/gateways/{gateway-id}/refresh |
| 326 | +``` |
