What is n8n-mcp-server GEMINI.md?

Project instructions for Gemini CLI in an n8n MCP server codebase. n8n is a workflow-automation platform, and MCP is a way for AI assistants to call tools provided by another program.

Use them when working on the Python server that lets AI assistants manage n8n workflows, including creating, searching, updating, deleting, and activating workflows.

They give an AI assistant the project's overview, technologies, file layout, prerequisites, and operating instructions in one place.

Token cost

What it costs to keep this loaded

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	$0.00831	$0.00831
Opus 5	$0.00415	$0.00415
Sonnet 5	$0.00166	$0.00166
Haiku 4.5	$0.00083	$0.00083

Security

Grade A, and why

n8n-mcp-server GEMINI.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 9d 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

This project is a Python-based server that implements the Model Context Protocol (MCP) to manage n8n workflows. It allows AI assistants to interact with n8n programmatically, enabling them to create, list, search, update, delete, activate, and deactivate workflows.

The server is built using the following main technologies:

Python 3.8+: The core programming language.
MCP (Model Context Protocol): The server implements the mcp library to communicate with AI assistants.
httpx: An asynchronous HTTP client used to interact with the n8n API.
Pydantic: Used for data validation and settings management.
structlog: For structured logging.

The project is structured as follows:

src/n8n_mcp/: Contains the main source code.
- server.py: The main MCP server implementation, which defines the available tools and handles tool calls.
- client.py: The n8n API client, which handles all communication with the n8n instance.
- config.py: The configuration management module, which uses Pydantic to load and validate settings from a file or environment variables.
- logging_config.py: The logging configuration module.
tests/: Contains the tests for the project.
config/: Contains the configuration files.
requirements.txt: The list of Python dependencies.

Building and Running

Prerequisites

Python 3.8+
An n8n instance (cloud or self-hosted) with an API key.

Installation

Clone the repository:

git clone https://github.com/yourusername/n8n-mcp-server.git
cd n8n-mcp-server

Create and activate a virtual environment:

python -m venv venv
source venv/bin/activate

Install the dependencies:
```
pip install -r requirements.txt
```

Configuration

Copy the example configuration file:

cp config/config.example.json config/config.json

Edit config/config.json with your n8n instance details (base URL and API key).

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.
