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:

1. 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

2. 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.

3. 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)

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.

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+) and the workflow's "Available in MCP" setting.
• pinData is keyed by node name, and every value is an array of items wrapped as {"json": {...}} — {"Webhook": [{"json": {"id": "123"}}]}, never a flat object. It must be non-empty.
• triggerNodeName picks the trigger node to start from (defaults to the detected one; n8n requires it whenever inputs are given).
• Both run methods execute the workflow's nodes for real. direct runs every node; pinned pins only trigger nodes, nodes with credentials and HTTP Request nodes, so Code, Set, If and credential-free I/O (Execute Command, file read/write) still run. Confirm with the user before running a workflow that writes anywhere.
• executionMode applies to direct: manual (default) or production. It changes the execution context, not whether the run has side effects — a production run goes through the production execution path and is recorded as one. Only pass it when the user asked for one.
• timeoutMs is the client deadline for the official call (5000-600000; default 30000 for prepare, 300000 for pinned/direct).
• direct returns as soon as the run starts, so it reports success with an executionId regardless of how the run ends — poll n8n_executions({action: "get", id: executionId}) for the outcome. A dispatch n8n refuses outright comes back as OFFICIAL_MCP_ERROR, not EXECUTION_FAILED.
• A workflow whose "Available in MCP" setting is off answers WORKFLOW_NOT_EXPOSED; exposeToMcp: true turns the setting on and retries once. That is a visible, persistent change — ask the user first, and note that enabling it is itself a workflow update, so it can overwrite a concurrent UI edit.

Successful and routed responses state method and backend (public-api or official-mcp); an envelope rejected on argument validation may carry neither.

See WORKFLOW_GUIDE.md for runnable examples of each method.

---

Version History

n8n_workflow_versions reads two independent histories, selected with source:

• source: "local" (default) — the snapshots n8n-mcp takes before it changes a workflow. Any n8n version, no token, ids are numbers. Blind to edits made in the n8n UI. The only source that supports delete and prune.
• source: "native" — n8n's own workflow history, the same list the UI shows, including edits made by people. Needs N8N_MCP_ACCESS_TOKEN (n8n 2.34+; the native diff needs 2.36, where get_workflow_versions_diff shipped) and the workflow's "Available in MCP" setting; ids are opaque strings; list is capped at 50 with an offset; delete and prune are refused with MODE_NOT_SUPPORTED_FOR_SOURCE (n8n owns that retention). Native rollback is not pre-validated — validateBefore is accepted and ignored.

mode: "diff" compares two versions (versionId + toVersionId, both from the same source and workflow). A local diff (data.format: "n8n-mcp") reports added/removed/modified nodes as node IDs; a native diff (data.format: "n8n") is n8n's own payload with field-level before/after values. Branch on data.format rather than assuming field names.

Native modes hit the same consent gate as the routed run methods: a workflow whose "Available in MCP" setting is off answers WORKFLOW_NOT_EXPOSED, and re-running with exposeToMcp: true turns that setting on and retries once (the response then carries exposedToMcp: true). It is a visible, persistent change to the workflow — ask the user before passing it. timeoutMs (5000-600000) is the client deadline for the native call.

See WORKFLOW_GUIDE.md for every mode with runnable examples of both sources.

---

Data Table Management

n8n_manage_datatable is the MCP tool for managing data tables and rows from outside a workflow (table actions createTable/listTables/getTable/updateTable/deleteTable; row actions getRows/insertRows/updateRows/upsertRows/deleteRows, with filtering, pagination, and dryRun). Don't confuse it with the in-workflow nodes-base.dataTable node, which reads/writes rows during execution (see n8n-node-configuration → OPERATION_PATTERNS.md). Rule of thumb: MCP tool to set up a table once, workflow node to read/write on every execution. deleteRows requires a filter; use dryRun: true before bulk changes.

Column actions — addColumn, deleteColumn, renameColumn — change an existing table's columns, which the Public API cannot do; they run through n8n's MCP server and need N8N_MCP_ACCESS_TOKEN (n8n 2.34+). addColumn takes column: {name, type} (name starts with a letter, letters/digits/underscores only, at most 63 chars; type is string, number, boolean or date); deleteColumn/renameColumn take the columnId from getTable, and renameColumn puts the new column name in name. They address the table by project: projectId is resolved automatically when exactly one project is accessible, otherwise the call returns PROJECT_REQUIRED and lists the candidates — pass projectId (from n8n_list_catalog({kind: "projects"})) to skip resolution. Renaming the table is not a column action: use updateTable on the Public API.

deleteColumn drops the column's values along with the column, and there is no undo. That bites hardest where you'd least expect it: a column's type cannot be changed after creation, so "make this column a number" really means drop-and-re-add, which throws away everything in it. Read the values out with getRows first if they matter, and confirm with the user before dropping a populated column.

See OPERATIONS_GUIDE.md for all actions, filter conditions, and examples.

---

Workflow Folders

n8n_manage_folders organizes workflows into folders (actions create/list/get/rename/move/delete; n8n 2.19+, registered free Community tier and up). projectId defaults to 'personal'. Placing workflows happens in the workflow tools: parentFolderId on n8n_create_workflow, or the moveToFolder operation of n8n_update_partial_workflow (both n8n 2.32+; null = project root). Two things to internalize: a workflow's folder is write-only in n8n's API (verify placement via a folder's get counts, never by reading the workflow), and delete without transferToFolderId archives the folder's workflows (transferToFolderId: "0" moves them to the project root instead, keeping them active).

See WORKFLOW_GUIDE.md for all actions, list filters/counts, and the delete semantics.

---

Credential Management

n8n_manage_credentials is the unified credential tool: actions list, get, create, update, delete, getSchema. It never returns secrets — get/create/update strip the data field. Use getSchema before create to discover required fields. The optional includeUsage: true flag (on list/get) reverse-scans workflows and attaches usedIn: [{id, name, active}] + usageCount — use it before deleting or rotating a credential to see what breaks (it triggers a full client-side scan, caps at 5000 workflows, excludes archived, and degrades to a usageScanError field on failure).

See WORKFLOW_GUIDE.md for all actions, the includeUsage shape, security notes, and the safe delete/rotate workflow.

---

Agents

The three tools in this section exist only for n8n's instance-level MCP server (a separate endpoint from the Public API). n8n_manage_agents and n8n_explore_node_resources need N8N_MCP_ACCESS_TOKEN; n8n_list_catalog works without it and uses the token only for its team-project fallback. Other tools route individual operations through the same server — n8n_test_workflow prepare/pinned/direct, n8n_workflow_versions source: "native", the n8n_manage_datatable column actions — as described in their own sections; see "Tool Availability" below.

• n8n_manage_agents — create, configure, validate, run and publish persisted n8n Agents (a standalone assistant artifact: model, instructions, tools, skills, tasks, memory, channels — not the AI Agent workflow node). Actions: reference, search, get, create, mutate, validate, call, publish, unpublish, revert, versions, delete, discover_assets, verify_mcp_server, update_integration. Start with action: "reference", then discover_assets → create → mutate (one resource at a time, always the latest hash — n8n returns it as configHash and expects it back as args.baseConfigHash; a stale one comes back as STALE_CONFIG) → validate. publish only on explicit request; call runs the agent with real credentials and tools and may return approvals[] for the human to decide. timeoutMs is a top-level parameter (default 30000, 180000 for call), not part of args. Needs n8n 2.34+ with the agents module; on 2.36.x the agents runtime rejects azureOpenAiApi/aws credentials. Envelope error codes: NOT_CONFIGURED, INVALID_ARGS, STALE_CONFIG, AGENT_NOT_RUNNABLE, AGENT_TOOL_ERROR (a custom tool that failed to compile, or an unknown agentId), plus the shared OFFICIAL_MCP_* family (AUTH_FAILED, NOT_ENABLED, RATE_LIMITED, TOOL_UNAVAILABLE, URL_REJECTED, TIMEOUT, TRANSPORT_ERROR, ERROR). See n8n-agents skill's "Persisted n8n Agents" section for the full workflow.
• n8n_explore_node_resources — resolve the real values behind a node's loadOptions dropdown or resource-locator listSearch (Slack channels, Google Sheets tabs, model lists) using a live credential, instead of guessing an ID. Use it when get_node (standard detail) shows dynamicOptions: {methodName, methodType, dependsOn} on a property. Six parameters are required and none of them are inferred: nodeType (LONG form), version (the node typeVersion the method belongs to), methodName and methodType copied verbatim from dynamicOptions, and credentialType plus a credentialId of that type from n8n_manage_credentials({action: "list"}). Whatever the method dependsOn goes in currentNodeParameters, resource-locator values keeping their {__rl: true, mode: "id", value: "…"} shape. Each result's value is what belongs in the workflow parameter; name is display text only.
• n8n_list_catalog — list instance-level projects (personal project marked, gives projectId for n8n_manage_agents/n8n_manage_datatable) or tags. Works without the token via the Public API; with it configured, falls back to the official MCP server for team projects when the Public API's licence gate refuses (teamProjectsEnabled reports which).

---

Security & Audit

n8n_audit_instance combines n8n's built-in audit (categories credentials/database/nodes/instance/filesystem) with a custom deep scan (hardcoded_secrets, unauthenticated_webhooks, error_handling, data_retention). All parameters optional: categories, includeCustomScan (default true), customChecks, daysAbandonedWorkflow. Detected secrets are masked (first 6 + last 4 chars). Output is an actionable markdown report — summary table, findings by workflow, and a Remediation Playbook split into auto-fixable / requires-review / requires-user-action.

See WORKFLOW_GUIDE.md for the two scanning approaches, examples, and remediation types in full.

---

Self-Help Tools

• tools_documentation() — overview of all tools; tools_documentation({topic, depth: "full"}) for a specific tool. Code node guides via topics javascript_code_node_guide / python_code_node_guide.
• AI agent guide — tools_documentation({topic: "ai_agents_guide", depth: "full"}) (no standalone tool); returns architecture, connections, tools, validation, best practices.
• n8n_health_check() — quick check; n8n_health_check({mode: "diagnostic"}) returns status, env vars, tool status, API connectivity. Both modes also return an officialMcp block — {configured, endpoint, reachable, toolCount, agentTools} — the preflight for everything gated on N8N_MCP_ACCESS_TOKEN: the agent tools, n8n_test_workflow's routed methods, native version history, the data-table column actions. Read it once before reaching for any of them, rather than discovering the gap through a NOT_CONFIGURED envelope mid-task.

See OPERATIONS_GUIDE.md for examples.

---

Tool Availability

Always Available (no n8n API needed):

• search_nodes, get_node
• validate_node, validate_workflow
• search_templates, get_template
• tools_documentation (includes the ai_agents_guide topic)

Requires n8n API (N8N_API_URL + N8N_API_KEY):

• n8n_create_workflow
• n8n_update_partial_workflow, n8n_update_full_workflow
• n8n_validate_workflow (by ID)
• n8n_list_workflows, n8n_get_workflow, n8n_delete_workflow
• n8n_test_workflow
• n8n_executions
• n8n_evaluations (reads: n8n 2.30+ with an API key created on 2.30+; run/cancel: n8n 2.32+ with a key created on 2.32+ — older keys lack the testRun scopes)
• n8n_deploy_template
• n8n_workflow_versions
• n8n_autofix_workflow
• n8n_manage_datatable
• n8n_manage_folders (folder CRUD: n8n 2.19+, registered Community tier and up; workflow placement via parentFolderId/moveToFolder: n8n 2.32+)
• n8n_manage_credentials
• n8n_audit_instance
• n8n_list_catalog (works without the token; needs it only for the team-project fallback)

Requires N8N_MCP_ACCESS_TOKEN (a separate token from n8n Settings → Instance-level MCP, in addition to the Public API credentials above):

• n8n_manage_agents
• n8n_explore_node_resources
• n8n_test_workflow with method: "prepare"/"pinned"/"direct" (also needs the workflow's "Available in MCP" setting)
• n8n_workflow_versions with source: "native" (also needs the workflow's "Available in MCP" setting)
• n8n_manage_datatable with addColumn/deleteColumn/renameColumn

If API tools unavailable, use templates and validation-only workflows.

Unified Tool Reference

• get_node — detail levels (minimal ~200 tok / standard ~1-2K, RECOMMENDED / full ~3-8K, sparingly) and modes (info default, docs, search_properties + propertyQuery, versions, compare, breaking, migrations). Deep dive in SEARCH_GUIDE.md.
• validate_node — modes full (default, errors/warnings/suggestions) and minimal (required-fields check); profiles minimal/runtime (default, recommended)/ai-friendly/strict. Deep dive in VALIDATION_GUIDE.md.

Best Practices

Do

• For simple workflows (<=5 nodes), use MCP tools directly — don't over-engineer the investigation
• Use patchNodeField for surgical edits to Code node content instead of replacing the entire node
• Use get_node({detail: "standard"}) for most use cases
• Specify validation profile explicitly (profile: "runtime")
• Use smart parameters (branch, case) for clarity
• Include intent parameter in workflow updates
• Follow search → get_node → validate workflow
• Iterate workflows (avg 56s between edits)
• Validate after every significant change
• Use includeExamples: true for real configs
• Use n8n_deploy_template for quick starts

Don't

• Use detail: "full" unless necessary (wastes tokens)
• Forget nodeType prefix (nodes-base.*)
• Skip validation profiles
• Try to build workflows in one shot (iterate!)
• Ignore auto-sanitization behavior
• Use full prefix (n8n-nodes-base.*) with search/validate tools
• Forget to activate workflows after building

---

Summary

Most Important:

1. Use get_node with detail: "standard" (default) - covers 95% of use cases
2. nodeType formats differ: nodes-base.* (search/validate) vs n8n-nodes-base.* (workflows)
3. Specify validation profiles (runtime recommended)
4. Use smart parameters (branch="true", case=0)
5. Include intent parameter in workflow updates
6. Auto-sanitization runs on ALL nodes during updates
7. Workflows can be activated via API (activateWorkflow operation)
8. Workflows are built iteratively (56s avg between edits)
9. Data tables managed with n8n_manage_datatable (CRUD + filtering)
10. Folders managed with n8n_manage_folders; workflow placement is write-only (verify via folder counts, not the workflow)
11. Credentials managed with n8n_manage_credentials (CRUD + schema discovery)
12. Security audits via n8n_audit_instance (built-in + custom deep scan)
13. AI agent guide available via tools_documentation({topic: "ai_agents_guide", depth: "full"})

Common Workflow:

1. search_nodes → find node
2. get_node → understand config
3. validate_node → check config
4. n8n_create_workflow → build
5. n8n_validate_workflow → verify
6. n8n_update_partial_workflow → iterate
7. activateWorkflow → go live!
