n8n-mcp-tools-expert

Expert guide for using n8n-mcp MCP tools effectively. Use when searching for nodes, validating configurations, accessing templates, managing workflows, managing credentials, auditing instance security, or using any n8n-mcp tool. Provides tool selection guidance, parameter formats, and common patterns. IMPORTANT — Always consult this skill before calling any n8n-mcp tool — it prevents common mistakes like wrong nodeType formats, incorrect parameter structures, and inefficient tool usage. If the user mentions n8n, workflows, nodes, or automation and you have n8n MCP tools available, use this skill first.

Quality

Content

77%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with concrete, executable tool calls and clearly sequenced validation-gated workflows. Its main weaknesses are verbosity from repeated content across sections and four missing reference files that the overview points to but which are absent from the bundle.

Suggestions

Add the four referenced bundle files (SEARCH_GUIDE.md, VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md, OPERATIONS_GUIDE.md) to the skill, or remove the dead links and inline the essential content.

De-duplicate the body: the Summary, Best Practices, and Common Mistakes sections repeat material already covered in Quick Reference, Tool Selection Guide, and Performance Characteristics — collapse overlaps to reduce tokens.

Consolidate the overlapping tool tables (Quick Reference 'Most Used Tools' and Performance Characteristics) into a single table to tighten the document.

DimensionReasoningScore

Conciseness

The body assumes Claude's competence (no preamble on what n8n/MCP is) but is ~390 lines with notable redundancy — the Summary restates Best Practices, the Performance table overlaps the Quick Reference table, and Common Mistakes appears both inline and as a table. It is mostly efficient but could be tightened, matching the 2 anchor rather than the lean 3.

2 / 3

Actionability

Provides fully executable, copy-paste-ready tool calls with exact parameters (e.g. `search_nodes({query: "slack"})`, `get_node({nodeType: "nodes-base.slack"})`) plus WRONG/CORRECT code contrasts, matching the executable-and-specific anchor of 3.

3 / 3

Workflow Clarity

Multi-step workflows are clearly sequenced with explicit validation checkpoints and feedback loops ("validate → fix → validate again", "Validate after every significant change", iterative workflow building with re-validation), matching the clear-sequence-with-validation anchor of 3.

3 / 3

Progressive Disclosure

The body is structured as an overview pointing to four well-signaled one-level-deep references (SEARCH_GUIDE.md, VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md, OPERATIONS_GUIDE.md), but none of these referenced files actually exist in the bundle, so the cross-file structure does not resolve. The signaling intent is strong, but the broken/dead references are a real defect that fits the 2 anchor (references present but not actually delivered) rather than the clean 3.

Description

100%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong across all dimensions: it states concrete capabilities, provides explicit trigger guidance for both what and when, and is tightly scoped to n8n-mcp MCP tools. It avoids vague fluff and uses third-person voice throughout.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "searching for nodes, validating configurations, accessing templates, managing workflows, managing credentials, auditing instance security" — matching the multiple-specific-actions anchor; it is not the single-domain anchor of 2.

3 / 3

Completeness

Explicitly answers what (tool selection guidance, parameter formats, common patterns) and when (explicit "Use when..." clause plus a second trigger), matching the both-what-and-when anchor.

3 / 3

Trigger Term Quality

"If the user mentions n8n, workflows, nodes, or automation" covers natural terms users would actually say; better than the missing-common-variations anchor of 2.

3 / 3

Distinctiveness Conflict Risk

Scoped to "n8n-mcp MCP tools" with a guard ("when you have n8n MCP tools available"), giving a clear niche unlikely to conflict; not the overlapping anchor of 2.
