GenieACS

genieacs-mcp is an MCP server for 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, and each tool's hints say which, so your client can ask before the ones that act.
• Read-only mode: GENIEACS_READ_ONLY=true serves only the two reading tools and the resources; GENIEACS_TOOLS=search_devices,reboot_device serves only the tools you name.
• Speaks MCP 2026-07-28 and every earlier version back to 2024-11-05, so new and old clients both connect, over stdio or stateless HTTP.
• 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:

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):

{

"mcpServers": { "genieacs": { "command": "npx", "args": ["-y", "genieacs-mcp"], "env": { "ACS_URL": "http://localhost:7557" } } } }

The same server in other clients:

# Claude Code

claude mcp add --transport stdio --env ACS_URL=http://localhost:7557 genieacs -- npx -y genieacs-mcp

Docker, over stdio (any client that starts a command)

docker run -i --rm -e ACS_URL=http://host.docker.internal:7557 drumsergio/genieacs-mcp:v0.4.0

// VS Code, .vscode/mcp.json

{ "servers": { "genieacs": { "type": "stdio", "command": "npx", "args": ["-y", "genieacs-mcp"], "env": { "ACS_URL": "http://localhost:7557" } } } }

# Codex, ~/.codex/config.toml

[mcp_servers.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.
