How do I connect from a development container not on `mcp-network`?

Use the host IP or special DNS name. On Docker Desktop (Mac/Windows) use `host.docker.internal: /sse`. On Linux, use the host’s IP or the Docker bridge gateway (e.g., `172.17.0.1`). The port must match the one published in `compose.yml`.

Does Cline support this server?

As of 2025/03/27, Cline does not support SSE, so it cannot be used with this server.

What credentials does it need?

It reads `PLAYWRIGHT_MCP_HOME` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.
