+
+## search_nodes (START HERE!)
+
+**Speed**: <20ms
+
+**Use when**: You know what you're looking for (keyword, service, use case)
+
+**Syntax**:
+```javascript
+search_nodes({
+  query: "slack",      // Required: search keywords
+  mode: "OR",          // Optional: OR (default), AND, FUZZY
+  limit: 20,           // Optional: max results (default 20)
+  source: "all",       // Optional: all, core, community, verified
+  includeExamples: false  // Optional: include template configs
+})
+```
+
+**Returns**:
+```javascript
+{
+  "query": "slack",
+  "results": [
+    {
+      "nodeType": "nodes-base.slack",                    // For search/validate tools
+      "workflowNodeType": "n8n-nodes-base.slack",       // For workflow tools
+      "displayName": "Slack",
+      "description": "Consume Slack API",
+      "category": "output",
+      "relevance": "high"
+    }
+  ]
+}
+```
+
+**Tips**:
+- Common searches: webhook, http, database, email, slack, google, ai
+- `OR` mode (default): matches any word
+- `AND` mode: requires all words
+- `FUZZY` mode: typo-tolerant (finds "slak" → Slack)
+- Use `source: "core"` for only built-in nodes
+- Use `includeExamples: true` for real-world configs
+
+---
+
+## get_node (UNIFIED NODE INFORMATION)
+
+The `get_node` tool provides all node information with different detail levels and modes.
+
+### Detail Levels (mode="info")
+
+| Detail | Tokens | Use When |
+|--------|--------|----------|
+| `minimal` | ~200 | Quick metadata check |
+| `standard` | ~1-2K | **Most use cases (DEFAULT)** |
+| `full` | ~3-8K | Complex debugging only |
+
+### Standard Detail (RECOMMENDED)
+
+**Speed**: <10ms | **Size**: ~1-2K tokens
+
+**Use when**: You've found the node and need configuration details
+
+```javascript
+get_node({
+  nodeType: "nodes-base.slack",      // Required: SHORT prefix format
+  includeExamples: true              // Optional: get real template configs
+})
+// detail="standard" is the default
+```
+
+**Returns**:
+- Available operations and resources
+- Essential properties (10-20 most common)
+- Metadata (isAITool, isTrigger, hasCredentials)
+- Real examples from templates (if includeExamples: true)
+
+### Minimal Detail
+
+**Speed**: <5ms | **Size**: ~200 tokens
+
+**Use when**: Just need basic metadata
+
+```javascript
+get_node({
+  nodeType: "nodes-base.slack",
+  detail: "minimal"
+})
+```
+
+**Returns**: nodeType, displayName, description, category
+
+### Full Detail (USE SPARINGLY)
+
+**Speed**: <100ms | **Size**: ~3-8K tokens
+
+**Use when**: Debugging complex configuration, need complete schema
+
+```javascript
+get_node({
+  nodeType: "nodes-base.httpRequest",
+  detail: "full"
+})
+```
+
+**Warning**: Large payload! Use `standard` for most cases.
+
+---
+
+## get_node Modes
+
+### mode="docs" (READABLE DOCUMENTATION)
+
+**Use when**: Need human-readable documentation with examples
+
+```javascript
+get_node({
+  nodeType: "nodes-base.slack",
+  mode: "docs"
+})
+```
+
+**Returns**: Formatted markdown with:
+- Usage examples
+- Authentication guide
+- Common patterns
+- Best practices
+
+**Better than raw schema for learning!**
+
+### mode="search_properties" (FIND SPECIFIC FIELDS)
+
+**Use when**: Looking for specific property in a node
+
+```javascript
+get_node({
+  nodeType: "nodes-base.httpRequest",
+  mode: "search_properties",
+  propertyQuery: "auth",           // Required for this mode
+  maxPropertyResults: 20           // Optional: default 20
+})
+```
+
+**Returns**: Property paths and descriptions matching query
+
+**Common searches**: auth, header, body, json, url, method, credential
+
+### mode="versions" (VERSION HISTORY)
+
+**Use when**: Need to check node version history
+
+```javascript
+get_node({
+  nodeType: "nodes-base.executeWorkflow",
+  mode: "versions"
+})
+```
+
+**Returns**: Version history with breaking changes flags
+
+### mode="compare" (COMPARE VERSIONS)
+
+**Use when**: Need to see differences between versions
+
+```javascript
+get_node({
+  nodeType: "nodes-base.httpRequest",
+  mode: "compare",
+  fromVersion: "3.0",
+  toVersion: "4.1"       // Optional: defaults to latest
+})
+```
+
+**Returns**: Property-level changes between versions
+
+### mode="breaking" (BREAKING CHANGES ONLY)
+
+**Use when**: Checking for breaking changes before upgrades
+
+```javascript
+get_node({
+  nodeType: "nodes-base.httpRequest",
+  mode: "breaking",
+  fromVersion: "3.0"
+})
+```
+
+**Returns**: Only breaking changes (not all changes)
+
+### mode="migrations" (AUTO-MIGRATABLE)
+
+**Use when**: Checking what can be auto-migrated
+
+```javascript
+get_node({
+  nodeType: "nodes-base.httpRequest",
+  mode: "migrations",
+  fromVersion: "3.0"
+})
+```
+
+**Returns**: Changes that can be automatically migrated
+
+---
+
+## Additional Parameters
+
+### includeTypeInfo
+
+Add type structure metadata (validation rules, JS types)
+
+```javascript
+get_node({
+  nodeType: "nodes-base.if",
+  includeTypeInfo: true   // Adds ~80-120 tokens per property
+})
+```
+
+Use for complex nodes like filter, resourceMapper
+
+### includeExamples
+
+Include real-world configuration examples from templates
+
+```javascript
+get_node({
+  nodeType: "nodes-base.slack",
+  includeExamples: true   // Adds ~200-400 tokens per example
+})
+```
+
+Only works with `mode: "info"` and `detail: "standard"`
+
+---
+
+## Common Workflow: Finding & Configuring
+
+```
+Step 1: Search
+search_nodes({query: "slack"})
+→ Returns: nodes-base.slack
+
+Step 2: Get Operations (18s avg thinking time)
+get_node({
+  nodeType: "nodes-base.slack",
+  includeExamples: true
+})
+→ Returns: operations list + example configs
+
+Step 3: Validate Config
+validate_node({
+  nodeType: "nodes-base.slack",
+  config: {resource: "channel", operation: "create"},
+  profile: "runtime"
+})
+→ Returns: validation result
+
+Step 4: Use in Workflow
+(Configuration ready!)
+```
+
+**Most common pattern**: search → get_node (18s average)
+
+---
+
+## Quick Comparison
+
+| Tool/Mode | When to Use | Speed | Size |
+|-----------|-------------|-------|------|
+| `search_nodes` | Find by keyword | <20ms | Small |
+| `get_node (standard)` | **Get config (DEFAULT)** | <10ms | 1-2K |
+| `get_node (minimal)` | Quick metadata | <5ms | 200 |
+| `get_node (full)` | Complex debugging | <100ms | 3-8K |
+| `get_node (docs)` | Learn usage | Fast | Medium |
+| `get_node (search_properties)` | Find specific field | Fast | Small |
+| `get_node (versions)` | Check versions | Fast | Small |
+
+**Best Practice**: search → get_node(standard) → validate
+
+---
+
+## nodeType Format (CRITICAL!)
+
+**Search/Validate Tools** (SHORT prefix):
+```javascript
+"nodes-base.slack"
+"nodes-base.httpRequest"
+"nodes-langchain.agent"
+```
+
+**Workflow Tools** (FULL prefix):
+```javascript
+"n8n-nodes-base.slack"
+"n8n-nodes-base.httpRequest"
+"@n8n/n8n-nodes-langchain.agent"
+```
+
+**Conversion**: search_nodes returns BOTH formats:
+```javascript
+{
+  "nodeType": "nodes-base.slack",          // Use with get_node, validate_node
+  "workflowNodeType": "n8n-nodes-base.slack"  // Use with n8n_create_workflow
+}
+```
+
+---
+
+## Examples
+
+### Find and Configure HTTP Request
+
+```javascript
+// Step 1: Search
+search_nodes({query: "http request"})
+
+// Step 2: Get standard info
+get_node({nodeType: "nodes-base.httpRequest"})
+
+// Step 3: Find auth options
+get_node({
+  nodeType: "nodes-base.httpRequest",
+  mode: "search_properties",
+  propertyQuery: "authentication"
+})
+
+// Step 4: Validate config
+validate_node({
+  nodeType: "nodes-base.httpRequest",
+  config: {method: "POST", url: "https://api.example.com"},
+  profile: "runtime"
+})
+```
+
+### Explore AI Nodes
+
+```javascript
+// Find all AI-related nodes
+search_nodes({query: "ai agent", source: "all"})
+
+// Get AI Agent documentation
+get_node({nodeType: "nodes-langchain.agent", mode: "docs"})
+
+// Get configuration details with examples
+get_node({
+  nodeType: "nodes-langchain.agent",
+  includeExamples: true
+})
+```
+
+### Check Version Compatibility
+
+```javascript
+// See all versions
+get_node({nodeType: "nodes-base.executeWorkflow", mode: "versions"})
+
+// Check breaking changes from v1 to v2
+get_node({
+  nodeType: "nodes-base.executeWorkflow",
+  mode: "breaking",
+  fromVersion: "1.0"
+})
+```
