aivy-mcp

An MCP server that lets your own AI assistant (Claude Code, Claude Desktop, ChatGPT, Codex, Cursor, ...) read and control your own solar + battery system through the Aivy Developer API by Ivy Energy.

Works with every brand Aivy runs: Sungrow, Sigenergy, FoxESS, AlphaESS, SolaX and more. The same tools, whatever the inverter.

1. Get a key

Open bridge.ivyenergy.com.au/developer, sign up or sign in, and create a key. Pick Read only to let an assistant look, or Read and control to let it change the energy mode, Ai+ settings and connect systems. The key sees exactly what your account sees, nothing more.

No hardware yet? Every key also lists demo sites (sandbox:..., replayed real data, read-only), so you can try everything first. Accounts and keys can also be created from the API itself; see the Quickstart.

2. Add the server

Claude Code:

claude mcp add aivy -e AIVY_API_KEY=aivy_sk_... -- uvx aivy-mcp

Claude Desktop / Cursor / any MCP client (mcpServers block):

{
  "mcpServers": {
    "aivy": {
      "command": "uvx",
      "args": ["aivy-mcp"],
      "env": { "AIVY_API_KEY": "aivy_sk_..." }
    }
  }
}

No uv? pipx run aivy-mcp or pip install aivy-mcp && aivy-mcp work too.

Assistants that cannot run local tools (ChatGPT in the browser) can use the HTTP API directly. Paste this into the chat:

Use the Aivy Developer API at https://bridge.ivyenergy.com.au/v1 with the header Authorization: Bearer aivy_sk_.... Read https://bridge.ivyenergy.com.au/v1/llms.txt first, then GET /sites.

3. Ask

• "How's my battery doing?"
• "Why did it charge at 3am?"
• "What are prices doing tonight? Should I sell?"
• "Plan the best time to sell tonight, keep 20%, then apply it."
• "Charge at 5 kW to 90% for the next two hours." (control key)
• "Make Ai+ a bit more aggressive on exports." (control key)
• "Connect my Sungrow inverter, serial A2340000001, NMI 2001234567." (control key)

For agents: the playbook

Tool descriptions say what each call does. The playbook says how to get a job done with them: which tools answer which questions, when to stop and confirm, how forced mode and its hand-back work, what each error means, and the step-by-step workflows (status, diagnosis, prices, earnings, selling tonight, keeping a reserve, charging now, connecting a system, Ai+ tuning). It is one text, delivered four ways:

Checking an agent against it

evals/cases.json holds conversation cases (the user's words, the tools a good agent calls in order, the ones it must not call, and whether the turn has to end in a question). evals/check.py judges a transcript:

# Claude Code, headless, with the server configured as "aivy":
claude -p "Sell at the best prices tonight, keep 20%." --output-format stream-json > t.json
python evals/check.py sell-tonight-propose t.json

A transcript can also be a plain list: [{"name": "get_status", "args": {}}], or {"calls": [...], "text": "final reply"}. Run the cases after changing the playbook, the tool descriptions or the model.

Tools

What the server enforces, whatever the assistant does

• A key sees only its owner's sites; writes need the control scope.
• A forced (manual) mode set through the API always reverts to the previous mode after duration_minutes (default 4 h, max 24 h).
• The SOC floor and grid export limits cannot be overridden.
• Every call is recorded with the key id and client; keys can be revoked in the app at any time and stop working immediately.
• Per-key rate limit (default 120/min). Readings refresh about once a minute.

Development

git clone https://github.com/IVYEnergy/aivy-mcp && cd aivy-mcp
uv run --with pytest pytest
uv run aivy-mcp            # needs AIVY_API_KEY

The package also lives in Ivy Energy's main repository under sdk/aivy-mcp; this public repository is where it is released from.
