Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00059 | $0.03366 |
| Opus 5 | $0.00030 | $0.01683 |
| Sonnet 5 | $0.00012 | $0.00673 |
| Haiku 4.5 | $0.00006 | $0.00337 |
Grade A, and why
n8n-mcp-tools-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts

Quick Reference
Most Used Tools (by success rate)
| Tool | Use When | Success Rate | Speed |
|---|---|---|---|
search_nodes |
Finding nodes by keyword | 99.9% | <20ms |
get_node_essentials |
Understanding node operations | 91.7% | <10ms |
validate_node_operation |
Checking configurations | Varies | <100ms |
n8n_create_workflow |
Creating workflows | 96.8% | 100-500ms |
n8n_update_partial_workflow |
Editing workflows (MOST USED!) | 99.0% | 50-200ms |
validate_workflow |
Checking complete workflow | 95.5% | 100-500ms |
Tool Selection Guide
Finding the Right Node
Workflow:
1. search_nodes({query: "keyword"})
2. get_node_essentials({nodeType: "nodes-base.name"})
3. [Optional] get_node_documentation({nodeType: "nodes-base.name"})
Example:
// Step 1: Search
search_nodes({query: "slack"})
// Returns: nodes-base.slack
// Step 2: Get details (18s avg between steps)
get_node_essentials({nodeType: "nodes-base.slack"})
// Returns: operations, properties, examples
Common pattern: search → essentials (18s average)
Validating Configuration
Workflow:
1. validate_node_minimal({nodeType, config: {}}) - Check required fields
2. validate_node_operation({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
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

n8n-mcp-tools-expert is a skill published in the GitHub repository echoleesong/claude-skills-plugin (4 stars, last pushed 3mo ago), licensed MIT. It adds 59 tokens to every session and 3,366 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
