よくある質問

1

What are the prerequisites?

Python 3.10 or later, uv package manager, and a Pharo image with PharoSmalltalkInteropServer installed.

2

How do I configure the server port?

Set the `PHARO_SIS_PORT` environment variable (default 8086).

3

Does the server work without a live Pharo instance?

No, a running Pharo image with PharoSmalltalkInteropServer is required. Tests use mocking to avoid this dependency.

4

What transports or authentication are supported?

The README only describes local execution via stdio (MCP default). No authentication or alternative transports are mentioned.

5

Can I add custom settings beyond the documented ones?

Yes, the `apply_settings` tool accepts arbitrary key‑value pairs; the documented setting is `stackSize` (default 100).
