n8n-mcp-tools-expert

Expert guide for using n8n-mcp MCP tools effectively. Use when searching for nodes, validating configurations, accessing templates, managing workflows, organizing workflows into folders, 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

70%Weight 40%Scale 1-5

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 strong, well-sequenced validation workflows and explicit safeguards for destructive and batch operations. Its main weaknesses are noticeable redundancy across repeated tables and summary sections, and progressive disclosure that points to guide files not actually bundled with the skill.

Suggestions

Ship the four referenced guide files (SEARCH_GUIDE.md, VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md, OPERATIONS_GUIDE.md) in the bundle, or remove the dead links and inline only what is needed.

Remove redundancy: drop the Performance Characteristics table (its speeds duplicate the Quick Reference table) and trim the Summary section that restates Best Practices and Tool Categories.

Collapse the Common Mistakes table where it restates the Critical nodeType Formats and Node JSON Hygiene sections, keeping one canonical location.

DimensionReasoningScore

Conciseness

Core content is dense and largely n8n-mcp-specific knowledge Claude would not already know, but the 480-line body has real redundancy: tool speeds appear in both the Quick Reference table and the Performance Characteristics table, the Common Mistakes table restates the nodeType/credential sections, and the Summary restates Best Practices.

3 / 5

Actionability

Provides concrete executable guidance with exact tool signatures and parameter formats (e.g. `search_nodes({query: "slack"})`, credential nesting `{httpHeaderAuth: {id, name}}`, nodeType prefix rules); a few examples are illustrative ❌/✅ comments rather than full runnable scripts, and full worked examples are deferred to the guides.

4 / 5

Workflow Clarity

Multi-step processes are clearly sequenced with explicit validation feedback loops ("validate → fix → validate again until clean") and destructive/batch safeguards ("use dryRun: true before bulk changes", "confirm with the user before dropping a populated column", "Confirm with the user before running a workflow that writes anywhere").

5 / 5

Progressive Disclosure

Structure is sectioned and references are clearly signaled and one-level-deep, but the four referenced guide files (SEARCH_GUIDE.md, VALIDATION_GUIDE.md, WORKFLOW_GUIDE.md, OPERATIONS_GUIDE.md) are not present in the bundle, so the navigation links are broken, and substantial detail that the guides are meant to offload remains inlined in the long body.

Description

87%Weight 40%Scale 1-5

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 a strong, third-person trigger description that explicitly covers both what the skill does and when to use it, with a well-scoped niche and good natural trigger terms. It is slightly held back from full marks on specificity and trigger breadth because actions and synonyms are at the domain level rather than fully granular.

DimensionReasoningScore

Specificity

Lists several concrete actions ("searching for nodes, validating configurations, accessing templates, managing workflows, organizing workflows into folders, managing credentials, auditing instance security") plus tool selection guidance and parameter formats; actions are domain-level rather than granular, leaving minor coverage gaps.

4 / 5

Completeness

Explicitly answers both what ("Expert guide for using n8n-mcp MCP tools... Provides tool selection guidance, parameter formats, and common patterns") and when ("Use when searching for nodes..."; "If the user mentions n8n, workflows, nodes, or automation... use this skill first") with concrete trigger phrases.

5 / 5

Trigger Term Quality

Strong natural trigger coverage ("n8n, workflows, nodes, or automation") plus "n8n-mcp" and per-action phrases; a few natural synonyms/variations are missing, short of comprehensive.

4 / 5

Distinctiveness Conflict Risk

Clear niche scoped to n8n-mcp MCP tools, with the qualifier "you have n8n MCP tools available" keeping the broad term "automation" from overlapping unrelated skills; minimal conflict risk.
