## [2.28.8] - 2025-12-07
|
||||
|
||||
### Bug Fixes
|
||||
|
||||
**Multi-tenant: handleValidateWorkflow missing context parameter (#474)**
|
||||
|
||||
Fixed `n8n_validate_workflow` tool failing in multi-tenant mode with error:
|
||||
`"n8n API not configured. Please set N8N_API_URL and N8N_API_KEY environment variables."`
|
||||
|
||||
- **Root Cause**: `handleValidateWorkflow` called `handleGetWorkflow` without passing the `context` parameter
|
||||
- **Impact**: Multi-tenant deployments could not use the `n8n_validate_workflow` tool
|
||||
- **Solution**: Pass `context` parameter to `handleGetWorkflow` call (line 987)

## [2.28.7] - 2025-12-05
|
||||
|
||||
### Bug Fixes
|
||||
|
||||
**Memory Leak: MCP Server Cleanup on Session Removal (#471)**
|
||||
|
||||
Fixed memory leak where `N8NDocumentationMCPServer` objects were not properly closed when sessions were removed, causing memory growth over time.
|
||||
|
||||
- **Root Cause**: `removeSession()` deleted server from map but didn't call cleanup methods
|
||||
- **Evidence**: Production server memory grew from ~10% to ~35% in 43 minutes (~1GB growth with 4GB container)
|
||||
|
||||
- **Solution**:
|
||||
- Added `close()` method to `N8NDocumentationMCPServer` that:
|
||||
- Calls `server.close()` (MCP SDK cleanup)
|
||||
- Calls `cache.destroy()` to stop cleanup timer and clear entries
|
||||
- Closes database connection properly
|
||||
- Nullifies service references to help GC
|
||||
- Updated `removeSession()` to call `server.close()` before releasing references
|
||||
|
||||
- **Files Changed**:
|
||||
- `src/mcp/server.ts` - Added `close()` method
|
||||
- `src/http-server-single-session.ts` - Call `server.close()` in `removeSession()`

## [2.28.6] - 2025-12-05
|
||||
|
||||
### Bug Fixes
|
||||
|
||||
**Test Updates for v2.28.5 Behavior Changes**
|
||||
|
||||
Fixed test expectations to match v2.28.5 implementation changes:
|
||||
|
||||
- **n8n-version tests**: Updated to verify 'v' prefix support in version strings (e.g., `v1.2.3`)
|
||||
- **n8n-validation tests**: Updated expectations for empty settings handling - now returns minimal defaults `{ executionOrder: 'v1' }` instead of `{}` to avoid n8n API rejection (Issue #431)
