n8n-MCP is a Model Context Protocol server that gives AI assistants structured knowledge of n8n's workflow-automation nodes, including their properties, operations, documentation, and examples. It helps developers use AI assistants to create and work with n8n workflows. The catalogue contains skills, agents, and instructions for using it.

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 | $0.01570 | $0.01570 |
| Opus 5.5 | $0.00628 | $0.00628 |
| Sonnet 5.5 | $0.00314 | $0.00314 |
| Haiku 4.5 | $0.00157 | $0.00157 |
Grade A, and why
n8n-mcp AGENTS.md 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 1mo 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.

Project Overview
n8n-mcp is a Model Context Protocol server that gives AI assistants access to n8n node documentation, workflow validation, and workflow management. Documentation and validation tools work offline against the bundled SQLite node database. Management tools prefixed with n8n_ operate on a live n8n instance and require API configuration.
Project Structure & Module Organization
Core TypeScript lives in src/. Important subsystems include:
src/mcp/— MCP server, request handlers, tool definitions and documentation, and bundled skillssrc/database/— SQLite adapters, repositories, FTS5 search, and migrationssrc/loaders/,src/parsers/,src/mappers/— node loading, metadata parsing, and documentation mappingsrc/services/— validation, workflow diffing and autofix, node/version lookup, the n8n API client, and security scannerssrc/templates/andsrc/community/— workflow-template and community-node ingestion and documentationsrc/telemetry/,src/triggers/, andsrc/n8n/— telemetry, trigger detection, and the n8n community-node wrappersrc/scripts/— maintenance scripts compiled todist/scripts/src/types/,src/constants/, andsrc/utils/— shared types, constants, and helperssrc/http-server*.ts— HTTP transports and session persistencesrc/mcp-engine.tsandsrc/mcp-tools-engine.ts— APIs for embedding the server
Tests mirror the source areas in tests/unit/ and tests/integration/, with fixtures, factories, helpers, and mocks under tests/. React/Vite apps live in ui-apps/src/, repository utilities in scripts/, documentation in docs/, and generated skills and databases in data/. Treat dist/, coverage output, and ui-apps/dist/ as generated; do not edit them directly.
Architecture & MCP Conventions
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 AGENTS.md is an instructions file published in the GitHub repository czlonkowski/n8n-mcp (23,116 stars, last pushed today), licensed MIT. It adds 1,570 tokens to every session, about $0.0063 per session on Opus 5.5. 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 2026-08-30.
