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 | $0.07234 | $0.07234 |
| Opus 5 | $0.03617 | $0.03617 |
| Sonnet 5 | $0.01447 | $0.01447 |
| Haiku 4.5 | $0.00723 | $0.00723 |
Grade A, and why
n8n-mcp CLAUDE.md scanned grade A with 1 finding 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 8d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
n8n-mcp is a comprehensive documentation and knowledge server that provides AI assistants with complete access to n8n node information through the Model Context Protocol (MCP). It serves as a bridge between n8n's workflow automation platform and AI models, enabling them to understand and work with n8n nodes effectively.
✅ Latest Updates (v2.7.4)
Update (v2.7.4) - Self-Documenting MCP Tools:
- ✅ RENAMED: start_here_workflow_guide → tools_documentation - More descriptive name
- ✅ NEW: Depth parameter - Control documentation detail level with "essentials" or "full"
- ✅ NEW: Per-tool documentation - Get help for any specific tool by name
- ✅ Concise by default - Essential info only, unless full depth requested
- ✅ LLM-friendly format - Plain text, not JSON for better readability
- ✅ Two-tier documentation:
- Essentials: Brief description, key parameters, example, performance, 2-3 tips
- Full: Complete documentation with all parameters, examples, use cases, best practices, pitfalls
- ✅ Quick reference - Call without parameters for immediate help
- ✅ 8 documented tools - Comprehensive docs for most commonly used tools
- ✅ Performance guidance - Clear indication of which tools are fast vs slow
- ✅ Error prevention - Common pitfalls documented upfront
Update (v2.7.0) - Diff-Based Workflow Editing with Transactional Updates:
- ✅ NEW: n8n_update_partial_workflow tool - Update workflows using diff operations for precise, incremental changes
- ✅ RENAMED: n8n_update_workflow → n8n_update_full_workflow - Clarifies that it replaces the entire workflow
- ✅ NEW: WorkflowDiffEngine - Applies targeted edits without sending full workflow JSON
- ✅ 80-90% token savings - Only send the changes, not the entire workflow
- ✅ 13 diff operations - addNode, removeNode, updateNode, moveNode, enableNode, disableNode, addConnection, removeConnection, updateConnection, updateSettings, updateName, addTag, removeTag
- ✅ Smart node references - Use either node ID or name for operations
- ✅ Transaction safety - Validates all operations before applying any changes
- ✅ Validation-only mode - Test your diff operations without applying them
- ✅ Comprehensive test coverage - All operations and edge cases tested
- ✅ Example guide - See workflow-diff-examples.md for usage patterns
- ✅ FIXED: MCP validation error - Simplified schema to fix "additional properties" error in Claude Desktop
- ✅ FIXED: n8n API validation - Updated cleanWorkflowForUpdate to remove all read-only fields
- ✅ FIXED: Claude Desktop compatibility - Added additionalProperties: true to handle extra metadata from Claude Desktop
- ✅ NEW: Transactional Updates - Two-pass processing allows adding nodes and connections in any order
- ✅ Operation Limit - Maximum 5 operations per request ensures reliability
- ✅ Order Independence - Add connections before nodes - engine handles dependencies automatically
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.
