 ### Runtime
 - Propagate `--timeout` / `MCPORTER_CALL_TIMEOUT` into MCP tool calls (SDK `timeout`, `resetTimeoutOnProgress`, `maxTotalTimeout`) so long-running requests are no longer capped by the SDK’s 60s default.
 
+### CLI
+- `mcporter generate-cli` once again treats single-token `--command` values (e.g., `./scripts/server.ts`) as STDIO transports instead of trying to coerce them into HTTP URLs, restoring the pre-0.6.1 behavior for ad-hoc scripts.
+
+### Configuration
+- Reintroduced support for `OPENCODE_CONFIG_DIR` so OpenCode imports continue to honor the documented directory override alongside `OPENCODE_CONFIG`.

+title: Windows & WSL tips
+summary: What to do when pnpm/test flows fail on NTFS-backed worktrees.
+---
+
+## Installing dependencies
+
+* `pnpm install` fails on `/mnt/c` because NTFS/DrvFs blocks `futime`. Clone/sync the repo to `$HOME` (ext4 inside WSL) and run `./runner pnpm install` there instead. Example: `rsync -a --delete --exclude node_modules /mnt/c/Projects/mcporter/ ~/mcporter-wsl/`.
+* Keep `$HOME/.bun/bin` and `$HOME/.local/share/pnpm` on your PATH before invoking `./runner`. Without Bun and pnpm the runner prints the guardrail error and exits.
+* If you *must* work from `/mnt/c`, remount with `metadata` support (`sudo mount -t drvfs C: /mnt/c -o metadata,uid=$(id -u),gid=$(id -g),umask=22,fmask=111`). Otherwise installs, chmods, and copyfile calls will continue to fail.
+
+## Running tests
+
+* Use the ext4 copy (`~/mcporter-wsl`) for `pnpm lint`, `pnpm typecheck`, and the Vitest suites. All tests pass there (71 files / 280 tests, 1 file and 2 tests skipped).
+* Whole-repo `pnpm test` on `/mnt/c` repeatedly times out because Vitest cannot start workers when the node_modules tree belongs to root or sits on NTFS. Copy the repo to ext4 or fix ownership before retrying.
+* When working cross-filesystem, remember to sync the edited source files back to the canonical `/mnt/c/Projects/mcporter` tree (e.g., `rsync -a ~/mcporter-wsl/src/cli/generate/{template,artifacts,fs-helpers}.ts /mnt/c/Projects/mcporter/src/cli/generate/`).
+* The stdio integration suite now vendors two tiny fixtures under `tests/fixtures/stdio-*.mjs` that spin up filesystem/memory MCP servers via `node`. The tests shell out to `process.execPath`, so make sure your PATH resolves `node` correctly (fnm/nvs setups sometimes expose only `node.exe` on Windows). If you need to debug them manually, run `./runner pnpm exec vitest run tests/stdio-servers.integration.test.ts` so the guardrails apply.
+
+## Windows-specific fixes in the repo
+
+* CLI generation now uses `src/cli/generate/fs-helpers.ts`: `markExecutable` ignores `EPERM/EINVAL/ENOSYS/EACCES` so NTFS builds no longer fail when setting executable bits.
+* `safeCopyFile` falls back to a manual read/write when DrvFs blocks `copyFile`, keeping Bun bundling stable on Windows.
+* These helpers only affect Windows/WSL behavior—Linux/macOS paths still perform real `chmod`/`copyFile`.
+* Regenerated CLIs (for example `node dist/cli.js generate-cli context7 --config config/mcporter.json --bundle /mnt/c/Temp/context7-cli.js --runtime node`) now complete successfully even when the bundle lives on `/mnt/c`, and the resulting executable runs with `node /mnt/c/Temp/context7-cli.js --help`.
+* When running `mcporter generate-cli` with `--command ./relative-script.ts`, the CLI no longer tries to normalize the path into an HTTP URL—relative/bare commands are always treated as STDIO transports now, matching the PowerShell/WSL behavior you expect.
