 ### Step 2: Create Required Deliverable
-Use the save_deliverable script to create your evidence:
+Use the save_deliverable MCP tool to create your evidence:
 
-```bash
-node save_deliverable.js SSRF_EVIDENCE '# SSRF Exploitation Evidence (Pipeline Test)
-
-**MCP Server Used:** {{MCP_SERVER}}
-**Test Site:** https://example.com
-**Screenshot:** ssrf-exploit-test.png
-**Status:** Browser isolation test successful
-
-## Exploitation Results
-- **Target:** Test SSRF vulnerability
-- **Method:** Server-Side Request Forgery via URL parameter
-- **Evidence:** Successfully forced server to make request to internal network
-- **Impact:** Demonstrated access to internal services and potential data exfiltration
-- **Proof:** Pipeline testing mode - simulated successful exploitation
-
-## Technical Details
-- **Vulnerability ID:** SSRF-VULN-01
-- **Exploitation Status:** Simulated Success (Pipeline Test)
-- **MCP Instance:** {{MCP_SERVER}}
-- **Attack Vector:** URL parameter manipulation
-- **Target:** Internal network services (localhost:8080)'

+Use `save_deliverable` MCP tool with:
+- `deliverable_type: "SSRF_EVIDENCE"`
+- `content: "# SSRF Exploitation Evidence (Pipeline Test)\n\n**MCP Server Used:** {{MCP_SERVER}}\n**Test Site:** https://example.com\n**Screenshot:** ssrf-exploit-test.png\n**Status:** Browser isolation test successful\n\n## Exploitation Results\n- **Target:** Test SSRF vulnerability\n- **Method:** Server-Side Request Forgery via URL parameter\n- **Evidence:** Successfully forced server to make request to internal network\n- **Impact:** Demonstrated access to internal services and potential data exfiltration\n- **Proof:** Pipeline testing mode - simulated successful exploitation\n\n## Technical Details\n- **Vulnerability ID:** SSRF-VULN-01\n- **Exploitation Status:** Simulated Success (Pipeline Test)\n- **MCP Instance:** {{MCP_SERVER}}\n- **Attack Vector:** URL parameter manipulation\n- **Target:** Internal network services (localhost:8080)"`
 
 This will automatically create `deliverables/ssrf_exploitation_evidence.md`.
