Connect · Claude Desktop

Claude Desktop.

Add PLCs.ai as a custom connector. Claude Desktop runs the OAuth sign-in for you.

  1. Open Settings → Connectors and click Add custom connector.
  2. Name it PLCs.ai and paste the URL:
text
https://mcp.plcs.ai/mcp
  1. Save, then click Connect. A browser window opens — sign in with your PLCs.ai account and pick the organization to connect.
  2. The plcs_* tools now appear in the chat's tools menu.

Option B — Config file (API key or on-prem)

For a bearer key or an on-prem appliance, use the mcp-remote bridge (it connects a desktop client to a remote Streamable-HTTP server and handles OAuth too). Open Settings → Developer → Edit Config and add:

json
{
  "mcpServers": {
    "plcs-ai": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote", "https://mcp.plcs.ai/mcp",
        "--header", "Authorization: Bearer plck_live_…"
      ]
    }
  }
}

Drop the --header line to use OAuth instead of a key. For on-prem, swap the URL for your appliance's.

Restart Claude Desktop after editing the config. mcp-remote needs Node 18+ on your PATH. Never commit this file — it can hold your key.
