Plctap MCP Server

状态: v0.6 (协议自动识别 + 透明代理 + 故障注入监听 + 八协议端点接入 (含 OPC UA 连接级诊断), 六端点可写 (IEC 104 / OPC UA 仅读); IEC 104 经 lib60870、EtherNet/IP 经 pycomm3 官方实现交叉验证, OPC UA 为 asyncua 官方库台架自洽验证)。. It runs locally over stdio via the published package.

People who work with fastmcp, fins and industrial automation and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

01 · Install Plctap

before you install - you'll need

Set PLCTAP_ALLOW_WRITE before connecting.

Claude Code

claude mcp add ymxc152-plctap -- uvx plctap

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "ymxc152-plctap": {
      "command": "uvx",
      "args": [
        "plctap"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions

repo age created 2026-09-03 - young repo, little track record yet

license MIT - declared in the repository

pypi package plctap - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.ymxc152 is GitHub-verified and matches the repo owner
