Common issues

Free

The top issues and their fixes.

"Unauthorized" when connecting

  • Confirm the key is copied with no trailing whitespace
  • Confirm the site uses HTTPS (StoreMCP refuses HTTP in production)
  • Confirm the key hasn't been revoked (check StoreMCP → API Keys)

"Tools missing" — client sees no tools

  • Confirm the module is enabled at StoreMCP → Modules
  • Confirm the acting user has the right capabilities (see permissions)
  • Some AI clients cache tool lists — restart the client

Slow responses

  • Check your site's PHP memory limit (recommend 256M+)
  • Enable StoreMCP's query cache (StoreMCP → Settings → Cache)
  • Reports over large date ranges are slower — narrow the window

validation_error on create/update

  • Check the parameter types (numbers vs strings)
  • Required fields are listed in each tool's reference page
  • For products with variations, create the parent as type: variable first

Changes don't show on the frontend

  • Flush the site's page cache (e.g. wp cache flush or your CDN)
  • If using a static host (e.g. WPCloud, Rocket), trigger a rebuild

"Pro required"

The tool you're calling is Pro-only. Activate a license at StoreMCP → License or work around it with Free tools.
