Self-check for the crg-mcp plugin.
|
|
|
|
Drives crg.cmd exactly the way the PI-Desktop MCP host does — `cmd /c crg.cmd`
|
|
with piped stdio and cwd = this folder — then reports the MCP handshake, the
|
|
tool list, and one real tool call. Run it from PowerShell:
|
|
|
|
powershell -NoProfile -ExecutionPolicy Bypass -File .\selfcheck.ps1
|
|
