### ✨ Features
|
||||
|
||||
**Tool Consolidation - Reduced Tool Count by 38%**
|
||||
|
||||
Major consolidation of MCP tools from 31 tools to 19 tools, using mode-based parameters for better AI agent ergonomics. This reduces cognitive load for AI agents while maintaining full functionality.
|
||||
|
||||
#### Consolidated Tools
|
||||
|
||||
**1. Node Tools - `get_node` Enhanced**
|
||||
|
||||
The `get_node` tool now supports additional modes:
|
||||
- `mode='docs'`: Replaces `get_node_documentation` - returns readable docs with examples
|
||||
- `mode='search_properties'`: Replaces `search_node_properties` - search within node properties
|
||||
|
||||
```javascript
|
||||
// Old: get_node_documentation
|
||||
get_node_documentation({nodeType: "nodes-base.slack"})
|
||||
// New: mode='docs'
|
||||
get_node({nodeType: "nodes-base.slack", mode: "docs"})
|
||||
|
||||
// Old: search_node_properties
|
||||
search_node_properties({nodeType: "nodes-base.httpRequest", query: "auth"})
|
||||
// New: mode='search_properties'
|
||||
get_node({nodeType: "nodes-base.httpRequest", mode: "search_properties", propertyQuery: "auth"})
|
||||
```
|
||||
|
||||
**2. Validation Tools - `validate_node` Unified**
|
||||
|
||||
Consolidated `validate_node_operation` and `validate_node_minimal` into single `validate_node`:
|
||||
- `mode='full'`: Full validation (replaces `validate_node_operation`)
|
||||
- `mode='minimal'`: Quick required fields check (replaces `validate_node_minimal`)
|
||||
|
||||
```javascript
|
||||
// Old: validate_node_operation
|
||||
validate_node_operation({nodeType: "nodes-base.slack", config: {...}})
|
||||
// New: mode='full' (default)
|
||||
validate_node({nodeType: "nodes-base.slack", config: {...}, mode: "full"})
|
||||
|
||||
// Old: validate_node_minimal
|
||||
validate_node_minimal({nodeType: "nodes-base.slack", config: {}})
|
||||
// New: mode='minimal'
|
||||
validate_node({nodeType: "nodes-base.slack", config: {}, mode: "minimal"})
|
||||
```
|
||||
|
||||
**3. Template Tools - `search_templates` Enhanced**
|
||||
|
||||
Consolidated `list_node_templates`, `search_templates_by_metadata`, and `get_templates_for_task`:
|
||||
- `searchMode='keyword'`: Search by keywords (default, was `search_templates`)
|
||||
- `searchMode='by_nodes'`: Search by node types (was `list_node_templates`)
|
||||
- `searchMode='by_metadata'`: Search by AI metadata (was `search_templates_by_metadata`)
|
||||
- `searchMode='by_task'`: Search by task type (was `get_templates_for_task`)
|
||||
|
||||
```javascript
|
||||
// Old: list_node_templates
|
||||
list_node_templates({nodeTypes: ["n8n-nodes-base.httpRequest"]})
|
||||
// New: searchMode='by_nodes'
|
||||
search_templates({searchMode: "by_nodes", nodeTypes: ["n8n-nodes-base.httpRequest"]})
|
||||
|
||||
// Old: get_templates_for_task
|
||||
get_templates_for_task({task: "webhook_processing"})
|
||||
// New: searchMode='by_task'
|
||||
search_templates({searchMode: "by_task", task: "webhook_processing"})
|
||||
```
|
||||
|
||||
**4. Workflow Getters - `n8n_get_workflow` Enhanced**
|
||||
|
||||
Consolidated `n8n_get_workflow_details`, `n8n_get_workflow_structure`, `n8n_get_workflow_minimal`:
|
||||
- `mode='full'`: Complete workflow data (default)
|
||||
- `mode='details'`: Workflow with metadata (was `n8n_get_workflow_details`)
|
||||
- `mode='structure'`: Nodes and connections only (was `n8n_get_workflow_structure`)
|
||||
- `mode='minimal'`: ID, name, active status (was `n8n_get_workflow_minimal`)
|
||||
|
||||
```javascript
|
||||
// Old: n8n_get_workflow_details
|
||||
n8n_get_workflow_details({id: "123"})
|
||||
// New: mode='details'
|
||||
n8n_get_workflow({id: "123", mode: "details"})
|
||||
|
||||
// Old: n8n_get_workflow_minimal
|
||||
n8n_get_workflow_minimal({id: "123"})
|
||||
// New: mode='minimal'
|
||||
n8n_get_workflow({id: "123", mode: "minimal"})
|
||||
```
|
||||
|
||||
**5. Execution Tools - `n8n_executions` Unified**
|
||||
|
||||
Consolidated `n8n_list_executions`, `n8n_get_execution`, `n8n_delete_execution`:
|
||||
- `action='list'`: List executions with filters
|
||||
- `action='get'`: Get single execution details
|
||||
- `action='delete'`: Delete an execution
|
||||
|
||||
```javascript
|
||||
// Old: n8n_list_executions
|
||||
n8n_list_executions({workflowId: "123", status: "success"})
|
||||
// New: action='list'
|
||||
n8n_executions({action: "list", workflowId: "123", status: "success"})
|
||||
|
||||
// Old: n8n_get_execution
|
||||
n8n_get_execution({id: "456"})
|
||||
// New: action='get'
|
||||
n8n_executions({action: "get", id: "456"})
|
||||
|
||||
// Old: n8n_delete_execution
|
||||
n8n_delete_execution({id: "456"})
|
||||
// New: action='delete'
|
||||
n8n_executions({action: "delete", id: "456"})
|
||||
```
|
||||
|
||||
### 🗑️ Removed Tools
|
||||
|
||||
The following tools have been removed (use consolidated equivalents):
|
||||
- `get_node_documentation` → `get_node` with `mode='docs'`
|
||||
- `search_node_properties` → `get_node` with `mode='search_properties'`
|
||||
- `get_property_dependencies` → Removed (use `validate_node` for dependency info)
|
||||
- `validate_node_operation` → `validate_node` with `mode='full'`
|
||||
- `validate_node_minimal` → `validate_node` with `mode='minimal'`
|
||||
- `list_node_templates` → `search_templates` with `searchMode='by_nodes'`
|
||||
- `search_templates_by_metadata` → `search_templates` with `searchMode='by_metadata'`
|
||||
- `get_templates_for_task` → `search_templates` with `searchMode='by_task'`
|
||||
- `n8n_get_workflow_details` → `n8n_get_workflow` with `mode='details'`
|
||||
- `n8n_get_workflow_structure` → `n8n_get_workflow` with `mode='structure'`
|
||||
- `n8n_get_workflow_minimal` → `n8n_get_workflow` with `mode='minimal'`
|
||||
- `n8n_list_executions` → `n8n_executions` with `action='list'`
|
||||
- `n8n_get_execution` → `n8n_executions` with `action='get'`
|
||||
- `n8n_delete_execution` → `n8n_executions` with `action='delete'`
|
||||
|
||||
### 📊 Impact
|
||||
|
||||
**Tool Count**: 31 → 19 tools (38% reduction)
|
||||
|
||||
**For AI Agents:**
|
||||
- Fewer tools to choose from reduces decision complexity
|
||||
- Mode-based parameters provide clear action disambiguation
|
||||
- Consistent patterns across tool categories
|
||||
- Backward-compatible parameter handling
|
||||
|
||||
**For Users:**
|
||||
- Simpler tool discovery and documentation
|
||||
- Consistent API design patterns
|
||||
- Reduced token usage in tool descriptions
|
||||
|
||||

### Memory Leak Fix (v2.20.2)
|
||||
|
||||
**Issue #330** identified a critical memory leak in long-running Docker/Kubernetes deployments:
|
||||
- **Before:** 100 MB → 2.2 GB over 72 hours (OOM kills)
|
||||
- **After:** Stable at 100-200 MB indefinitely
|
||||
|
||||
**Fixes Applied:**
|
||||
- ✅ Docker images now use better-sqlite3 by default (eliminates leak entirely)
|
||||
- ✅ sql.js fallback optimized (98% reduction in save frequency)
|
||||
- ✅ Removed unnecessary memory allocations (50% reduction per save)
|
||||
- ✅ Configurable save interval via `SQLJS_SAVE_INTERVAL_MS`
|
||||
|
||||

## ⚠️ Known Issues
|
||||
|
||||
### Claude Desktop Container Management
|
||||
|
||||
#### Container Accumulation (Fixed in v2.7.20+)
|
||||
Previous versions had an issue where containers would not properly clean up when Claude Desktop sessions ended. This has been fixed in v2.7.20+ with proper signal handling.
|
||||
|
||||
**For best container lifecycle management:**
|
||||
1. **Use the --init flag** (recommended) - Docker's init system ensures proper signal handling:
|
||||
```json
|
||||
{
|
||||
"mcpServers": {
|
||||
"n8n-mcp": {
|
||||
"command": "docker",
|
||||
"args": [
|
||||
"run", "-i", "--rm", "--init",
|
||||
"ghcr.io/czlonkowski/n8n-mcp:latest"
|
||||
]
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
2. **Ensure you're using v2.7.20 or later** - Check your version:
|
||||
```bash
|
||||
docker run --rm ghcr.io/czlonkowski/n8n-mcp:latest --version
|
||||
```
|
||||
|
||||

* - Start: search_nodes → get_node_essentials → get_node_for_task → validate_node_operation

* - Discovery: list_nodes({category:"trigger"}) for browsing categories
|

* - Quick Config: get_node_essentials("nodes-base.httpRequest") - only essential properties

* - Full Details: get_node_info only when essentials aren't enough
|

* - Validation: Use validate_node_operation for complex nodes (Slack, Google Sheets, etc.)
|

* - Start: search_nodes → get_node → validate_node
|
||||
* - Discovery: search_nodes({query:"trigger"}) for finding nodes
|

* - Quick Config: get_node("nodes-base.httpRequest", {detail:"standard"}) - only essential properties

* - Documentation: get_node("nodes-base.httpRequest", {mode:"docs"}) - readable markdown docs
|
||||
* - Find Properties: get_node("nodes-base.httpRequest", {mode:"search_properties", propertyQuery:"auth"})
