Connect weclapp to Claude
weclapp is a leading German Cloud ERP for SMBs covering CRM, sales, invoicing, purchasing, and warehousing. With AnythingMCP you connect weclapp to Claude AI via MCP and manage your ERP data in natural language — without writing custom REST glue.
The adapter is built on the weclapp REST API v2, which removed /customer and replaced it with the unified /party resource. If you've previously hit "weclapp connector doesn't work" with v1-pinned tooling (n8n templates, custom scripts), this is why — and this adapter sidesteps it.
What You Can Ask Claude

- "What articles are running low on stock?"
- "Find the party record for Müller GmbH and show their last 5 invoices"
- "Filter parties where
customerNumber-notnull=trueand country is DE"

Tip: Reduce Payload with properties
Claude works best when the tool returns small, focused payloads. Pass properties=id,customerNumber,company,email on weclapp_list_customers and a 100-row response shrinks from ~500 KB to ~10 KB — faster, cheaper, and easier for Claude to reason about.
