+=== FINAL QA SUMMARY ===
+Date: 2026-03-10
+Server: sage-x3-mcp v1.0.0
+
+TEST 1: stdio initialization + tools/list
+  - Initialize: PASS (serverInfo.name=sage-x3-mcp, version=1.0.0, protocolVersion=2024-11-05)
+  - tools/list count: 9/9 PASS
+  - Tool names match: PASS (sage_health, sage_query, sage_read, sage_search, sage_list_entities, sage_get_context, sage_soap_read, sage_soap_query, sage_describe_entity)
+  - readOnlyHint: 9/9 PASS (all tools have readOnlyHint: true)
+
+TEST 2: Tool invocation (sage_list_entities)
+  - JSON-RPC response received: PASS (id:3)
+  - Response structure valid: PASS (result.content[0].type=text, result.isError=true)
+  - Error expected with fake URL: "fetch failed" — correct behavior
+
+TEST 3: HTTP transport
+  - Server starts on configured port: PASS (port 13579)
+  - Initialize via HTTP POST /mcp: PASS (SSE response with serverInfo)
+  - tools/list via HTTP: PASS (9 tools returned)
+  - 404 for wrong path: PASS (HTTP 404)
+  - Requires Accept header: PASS (application/json, text/event-stream)
+
+TEST 4: Missing env vars
+  - Error message: "FATAL: Missing required environment variable: SAGE_X3_URL"
+  - Exit code: 1 (non-zero)
+  - Result: PASS
+
+NOTE: MCP SDK uses NDJSON framing (newline-delimited JSON), NOT LSP-style Content-Length headers.
+      HTTP transport uses SSE (Server-Sent Events) response format.
+
+Scenarios [4/4 pass] | Tools [9/9 registered] | Transports [2/2] | VERDICT: APPROVE
