Windows: doubled drive letter in logs directory path causes ENOENT

[mtmattei]

Bug

On Windows, the MCP server crashes on startup with:

Error: ENOENT: no such file or directory, mkdir 'C:\C:\Users\<user>\AppData\Local\npm-cache\_npx\...\node_modules\@instawp\mcp-wp\logs'

Notice the doubled C:\C:\ — the logs directory path is being constructed by prepending the drive letter to an already-absolute path.

Environment

• OS: Windows 11
• Node.js: v22.20.0
• Package: @instawp/mcp-wp (latest via npx -y)

Steps to Reproduce

1. On Windows, run npx -y @instawp/mcp-wp (with valid env vars set)
2. Server crashes immediately with the ENOENT error above

Root Cause

Likely in build/wordpress.js:60 — the mkdir call constructs a path that doubles the drive letter prefix. This is a common issue when using path.join() or string concatenation with an already-absolute Windows path.

Workaround

Manually creating the directory at the (incorrect) doubled path allows the server to start, but this shouldn't be necessary.
