MCP server for controlling Onkyo AV receivers over eISCP
Overview
From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.
[](https://github.com/SDNick484/mcp-server-onkyo/actions/workflows/ci.yml)
An MCP server for controlling Onkyo AV receivers over the network, so Claude Code, Claude Desktop, or any other MCP client can power them on, set the volume, mute them, and find them on your LAN.
It speaks eISCP (the Integra Serial Control Protocol over Ethernet, TCP/UDP port 60128) directly and needs nothing but the official MCP Python SDK.
Status: early / pre-alpha. This is also a learning project for MCP server development, so the code favors readability over cleverness. The current tools are tested against the bundled simulated receiver; validation on real hardware (TX-NR7100, TX-NR6050) is in progress.

Questions
What is the mcp-server-onkyo MCP server?
MCP server for controlling Onkyo AV receivers over eISCP
What tools does mcp-server-onkyo expose?
11 in total: 4 read-only, 7 that write, and 0 that can delete or overwrite. Every one is listed on this page with its risk.
Is mcp-server-onkyo safe to connect to an agent?
The audit found nothing in the source that contradicts what it says it does, and graded it B (89/100). Grade A is held back for packages that have also passed a sandboxed behavioural run, which is why a clean server reads B.
What credentials does mcp-server-onkyo need?
No credential environment variables were found in its source, so it appears to need none.
How current is this page?
The grade is for one exact copy of the source (5571650c91aa), read on 2026-10-11. The repository is watched and re-audited when it changes.
