Tool Selection Guide

Finding the Right Node

Workflow:

1. search_nodes({query: "keyword"})
2. get_node({nodeType: "nodes-base.name"})
3. [Optional] get_node({nodeType: "nodes-base.name", mode: "docs"})

Example:

// Step 1: Search
search_nodes({query: "slack"})
// Returns: nodes-base.slack

// Step 2: Get details
get_node({nodeType: "nodes-base.slack"})
// Returns: operations, properties, examples (standard detail)

// Step 3: Get readable documentation
get_node({nodeType: "nodes-base.slack", mode: "docs"})
// Returns: markdown documentation

Common pattern: search → get_node (18s average)

Validating Configuration

Workflow:

1. validate_node({nodeType, config: {}, mode: "minimal"}) - Check required fields
2. validate_node({nodeType, config, profile: "runtime"}) - Full validation
3. [Repeat] Fix errors, validate again

Common pattern: validate → fix → validate (23s thinking, 58s fixing per cycle)

Managing Workflows

Workflow:

1. n8n_create_workflow({name, nodes, connections})
2. n8n_validate_workflow({id})
3. n8n_update_partial_workflow({id, operations: [...]})
4. n8n_validate_workflow({id}) again
5. n8n_update_partial_workflow({id, operations: [{type: "activateWorkflow"}]})

Common pattern: iterative updates (56s average between edits)

Critical: Node JSON Hygiene When Creating Workflows

Three structural mistakes in generated node JSON break the n8n UI even when the workflow validates:

Never emit a credentials block with a placeholder ID. A fake ID like "id": "REPLACE_ME" renders the credential selector permanently disabled and non-clickable in the n8n UI ("No credentials yet") — the user has to recreate the node from scratch. If you don't know the real credential ID, omit the credentials block entirely; an absent block shows a normal empty dropdown the user can click. Use n8n_manage_credentials({action: "list"}) to discover real credential IDs first.

// ❌ Breaks the credential selector
"credentials": {"httpHeaderAuth": {"id": "REPLACE_ME", "name": "My API Key"}}

// ✅ Unknown ID → omit credentials block; user picks in UI
// ✅ Known ID (from n8n_manage_credentials list) → use the real ID

Generate UUID v4 values for node id — not human-readable strings like "http-list-node". n8n's frontend uses node IDs for form binding and credential component initialization; non-UUID IDs cause subtle UI breakage.
Use the current typeVersion for each node — check get_node rather than hardcoding remembered versions (e.g. httpRequest is at 4.4+, not 4.2).

Critical: nodeType Formats

Two different formats for different tools!

Format 1: Search/Validate Tools

// Use SHORT prefix
"nodes-base.slack"
"nodes-base.httpRequest"
"nodes-base.webhook"
"nodes-langchain.agent"

Tools that use this:

search_nodes (returns this format)
get_node
validate_node
validate_workflow

Format 2: Workflow Tools

// Use FULL prefix
"n8n-nodes-base.slack"
"n8n-nodes-base.httpRequest"
"n8n-nodes-base.webhook"
"@n8n/n8n-nodes-langchain.agent"

Tools that use this:

n8n_create_workflow
n8n_update_partial_workflow

Conversion

// search_nodes returns BOTH formats
{
  "nodeType": "nodes-base.slack",          // For search/validate tools
  "workflowNodeType": "n8n-nodes-base.slack"  // For workflow tools
}

Common Mistakes

Eight recurring mistakes. Two are worth showing in full because they silently corrupt structure:

// nodeType prefix (search/validate tools want the SHORT form)
get_node({nodeType: "slack"})              // ❌ missing prefix → "Node not found"
get_node({nodeType: "n8n-nodes-base.slack"}) // ❌ FULL prefix is for workflow tools
get_node({nodeType: "nodes-base.slack"})     // ✅

// credentials must be nested by type with {id, name} — not a flat string
updates: {credentials: "myApiKey"}                              // ❌
updates: {credentials: {httpHeaderAuth: {id: "abc123", name: "My API Key"}}}  // ✅

#	Mistake	Fix
1	Wrong nodeType format	SHORT `nodes-base.` for search/validate; FULL `n8n-nodes-base.` for workflow tools (see above)
2	`detail: "full"` by default	Default `standard` covers 95%; reach for `docs`/`search_properties` instead of `full`
3	No validation profile	Pass `profile: "runtime"` explicitly (`minimal`/`ai-friendly`/`strict` for other stages)
4	Ignoring auto-sanitization	ALL nodes sanitized on ANY update (operator structures, IF/Switch metadata); it can't fix broken connections or branch-count mismatches
5	Not using smart parameters	Use `branch: "true"` / `case: 0` instead of fragile `sourceIndex` math
6	Omitting `intent`	Always include `intent` on `n8n_update_partial_workflow` for better responses
7	`parameters` instead of `updates`	`updateNode` takes `updates: {...}`, not `parameters: {...}`
8	Wrong credential format	Nest by type with `{id, name}` (see above)

Full WRONG/CORRECT examples for each: see VALIDATION_GUIDE.md → Common Mistakes.

Tool Usage Patterns

Three patterns dominate real usage. Worked, step-by-step examples for each live in the reference guides.

Pattern 1 — Node Discovery (18s avg between steps): search_nodes({query}) → get_node({nodeType, includeExamples: true}). See SEARCH_GUIDE.md.
Pattern 2 — Validation Loop (23s thinking, 58s fixing): validate_node({profile: "runtime"}) → read errors → fix config → validate again until clean. See VALIDATION_GUIDE.md.
Pattern 3 — Workflow Editing (99.0% success, 56s avg between edits): iterate n8n_update_partial_workflow (with intent) → n8n_validate_workflow → finally activateWorkflow. Build iteratively, NOT one-shot. See WORKFLOW_GUIDE.md.

Detailed Guides

Node Discovery Tools

See SEARCH_GUIDE.md for:

search_nodes
get_node with detail levels (minimal, standard, full)
get_node modes (info, docs, search_properties, versions)

Validation Tools

See VALIDATION_GUIDE.md for:

Validation profiles explained
validate_node with modes (minimal, full)
validate_workflow complete structure
Auto-sanitization system
Handling validation errors

Workflow Management

See WORKFLOW_GUIDE.md for:

n8n_create_workflow
n8n_update_partial_workflow (21 operation types including patchNodeField, setNodeGroups, and moveToFolder!)
Smart parameters (branch, case)
AI connection types (8 types)
Workflow activation (activateWorkflow/deactivateWorkflow)
n8n_deploy_template
n8n_workflow_versions
n8n_manage_folders (folder CRUD + workflow placement)
n8n_manage_credentials (credential CRUD + schema discovery)
n8n_audit_instance (security auditing)

Templates, Data Tables & Self-Help

See OPERATIONS_GUIDE.md for:

search_templates / get_template / n8n_deploy_template examples
n8n_manage_datatable (full actions, filter conditions, examples)
tools_documentation, ai_agents_guide, n8n_health_check

Template Usage

The 2,700+ template library has three tools: search_templates (modes query/by_nodes/by_task/by_metadata), get_template (modes structure/full), and n8n_deploy_template (deploys to your instance with autoFix/autoUpgradeVersions, returns workflow ID + required credentials + fixes applied).

See OPERATIONS_GUIDE.md for full search/get/deploy examples.

Running Workflows

n8n_test_workflow has one required parameter (workflowId) and a method that picks the path:

`method`	Backend	What it does
`auto` (default)	Public API	Detects a webhook/form/chat trigger and fires it over HTTP — the workflow must be active. No such trigger → it reports that the workflow cannot be triggered and names the methods below. `auto` never runs anything through n8n's MCP server.
`trigger`	Public API	Same HTTP path, requested explicitly.
`prepare`	n8n's MCP server	Read-only: lists the nodes that need pinned data.
`pinned`	n8n's MCP server	Runs the workflow with `pinData` standing in for trigger, credentialed and HTTP Request nodes, and waits. Every other node still runs. A run that finishes in `error`/`crashed`/`canceled` comes back as `EXECUTION_FAILED` with the `executionId`.
`direct`	n8n's MCP server	Starts a run and returns once it has started; nothing is pinned, so every node runs. `message` or `data`/`headers` are forwarded to the trigger as input.

The last three need N8N_MCP_ACCESS_TOKEN (n8n 2.34+) a

Permission surface may require sandboxing
SKILL.md does not explicitly document security handling for sensitive n8n credentials or advise confirming user authorization before invoking destructive credential/workflow operations.
The skill depends on n8n-mcp tools with broad capabilities, but it does not itself limit or scope those permissions; security ultimately depends on MCP server configuration.
Quality score needs review
Permission surface needs review: secrets or environment access, network or browser access
Permission surface: secrets or environment access, network or browser access
