zont-mcp: Instructions file for Codex

AGENTS.md

zont-mcp AGENTS.md is an instructions file for Codex, OpenCode from MAB2908/zont-mcp. It costs 2,249 tokens per session, scanned A, original, MIT.

A working guide for zont-mcp, a local server that exposes tools for monitoring and controlling ZONT heating equipment through its official cloud service. ZONT controllers manage real home heating systems, so control actions can change physical equipment.

In plain words
What is it for?
Use it when installing zont-mcp or working with its device state, heating controls, inputs, history, analytics, configuration, commands, and archives.
Why use it?
It explains installation, configuration, and runtime safety before an agent uses the server. It makes clear that write operations are real-world actions, not just changes to test data.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is MAB2908/zont-mcp's own configuration. It tells Codex and OpenCode how to work on zont-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything zont-mcp configures →

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.

Security

Grade A, and why

zont-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 4d 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.

AGENTS.md — Working Guide for AI Agents

Русская версия

This document is written for AI models and autonomous agents that operate the zont-mcp MCP server — either by installing and configuring it, or by using its tools at runtime. Human-oriented documentation: README.md.


1. What you are operating

zont-mcp is a local MCP (Model Context Protocol) server exposing 38 tools for the ZONT heating ecosystem (BAXI Connect+ and compatible controllers) through the official ZONT cloud API. It controls real heating equipment in a real home. Treat every write tool as a physical-world action: switching modes changes the boiler's behaviour.

Tool groups: devices & state (5), heating control (6), I/O & guard (6), history & events (6), analytics (3), configuration (6), commands & archives (6).

2. Installation (if you are setting it up)

git clone https://github.com/MAB2908/zont-mcp.git
cd zont-mcp
python -m venv .venv
source .venv/bin/activate          # Windows: .venv\Scripts\activate
pip install -e .

Requires Python 3.11+. After installation the zont-mcp console command exists; python src/server.py is equivalent.

3. Configuration (if you are setting it up)

Credentials come only from environment variables or a .env file in the project root (template: .env.example). Required values:

Variable Meaning
ZONT_CLIENT_EMAIL ZONT account email — required
ZONT_TOKEN permanent API token — preferred
ZONT_LOGIN / ZONT_PASSWORD only for one-time token retrieval
ZONT_DEVICES_CACHE_TTL optional, device-list cache seconds (default 30)

Token retrieval flow: set login+password, leave token empty, start the server once — the token is printed to stderr; persist it as ZONT_TOKEN, then remove the password. The server exits immediately with a stderr explanation if credentials are missing or invalid. Client connection snippets (Claude Desktop, Claude Code, Cursor, VS Code): see README.md.

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.
