At a Glance & Executive Verdict
Genieacs MCP
Industrial & IoT · Local stdio
Quality: 52/100 (Good) | Auth: No auth required
Gx3 Cli MCP
Industrial & IoT · Local stdio
Quality: 52/100 (Good) | Auth: No auth required
Verdict Summary: Choose Genieacs MCP if you need specialized Industrial & IoT tools running via a local process. Choose Gx3 Cli MCP if your workspace requires Industrial & IoT integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Genieacs MCP when:
You need dedicated capabilities in the Industrial & IoT domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Primary tools included: Expose GenieACS resources as MCP JSON-RPC endpoints, Invoke CPE tools: reboot, refresh, firmware download, parameter set/get, Supports HTTP and stdio transports with authentication options.
Go-based MCP server that bridges any GenieACS (TR-069 ACS) instance, exposing device data, firmware management, and CPE actions (reboot, parameter refresh, firmware download) over JSON-RPC. Docker image available.
Read-only analysis of Mitsubishi Electric MELSEC PLC projects saved by GX Works3 (.gx3): trace why a coil never turns on through the ladder logic, find where a device is written and read, search by device comment, and separate conditions that arrive from physical inputs, HMI or network communication. Runs entirely locally and never modifies the project; no project-mutating command is exposed. Unofficial, not affiliated with Mitsubishi Electric.
