**genieacs-mcp** is an MCP server for [GenieACS](https://github.com/genieacs/genieacs), the open-source TR-069 ACS that manages routers, ONTs and other CPE devices. Add it to Claude Desktop, Cursor or any other MCP client and ask in plain words: which devices stopped informing last night, what firmware serial 000003 runs, reboot the ones tagged `pilot`. The assistant reads and acts through your GenieACS NBI with 7 resources and 12 tools; one Go binary, no database of its own.
## Features
- Find devices the way you would ask a colleague: by tag, model, firmware, last inform, or any TR-069 parameter (`search_devices` takes a MongoDB-style filter).
- Read a device's full parameter tree, its tasks and its faults, plus the presets, provisions and files on the ACS, as resources (`genieacs://device/{id}`, `genieacs://devices/list`, ...).
- Reboot a device, push firmware to it, refresh or set a parameter, or wake it with a connection request, from a chat.
- Tag devices, create or delete presets and provisions, and delete or retry tasks, so the assistant can fix what it finds.
- Every tool description says what it does, its limits and an example, so clients pick the right one without a prompt from you.
- Read versus act: `search_devices`, `get_parameter` and the seven resources only read; the other ten tools queue a task on a device or change the ACS.
- No read-only mode: point it at an ACS you are willing to let an assistant act on, and keep your client's tool-approval prompts on.
- Safe on a laptop: the HTTP transport listens on loopback only unless you set an address and a bearer token, and checks `Host` and `Origin` against DNS rebinding.
- One static Go binary for Linux, macOS and Windows on amd64 and arm64, also as an npm package (`npx genieacs-mcp`) and a Docker image.
## Quick start
You need a GenieACS whose NBI (port 7557) this machine can reach; without one, the family's demo stack gives you an ACS with a simulated router in about a minute:
```sh
curl -fsSLO https://raw.githubusercontent.com/GeiserX/genieacs-container/main/docker-compose.yml
docker compose --profile testing up -d # GenieACS + MongoDB + one simulated CPE, NBI on localhost:7557
```
Then add the server to a client that reads an `mcpServers` block (Claude Desktop, Cursor, Claude Code; in VS Code the `.vscode/mcp.json` key is `servers`):
```json
{
"mcpServers": {
"genieacs": {
"command": "npx",
"args": ["-y", "genieacs-mcp"],
"env": { "ACS_URL": "http://localhost:7557" }
}
}
}
```
It worked when you ask "which devices does the ACS know about?" and the assistant answers with device ids such as `202BC1-BM632w-000000` (the demo stack) or your own. Docker, the HTTP transport and a local build are in [Getting started](https://geiserx.github.io/genieacs-mcp/getting-started/).
