Connect weclapp to ChatGPT
weclapp is a leading German Cloud ERP for SMBs. Using AnythingMCP you can expose weclapp data to ChatGPT through MCP and query customers, orders, invoices, and inventory in natural language.
The adapter targets the weclapp REST API v2 — /customer was removed in v2 and unified into /party, which is why many third-party weclapp integrations break silently. This adapter handles the migration for you.
Quick Setup
git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
- In weclapp, generate an API token under My Settings → API
- Open
http://localhost:3000/connectors/storeand import weclapp Cloud ERP - Provide
WECLAPP_TENANT(your subdomain, e.g.acmefromacme.weclapp.com) andWECLAPP_API_TOKEN - Assign the connector to an MCP server
Connect to ChatGPT
ChatGPT MCP support is rolling out via the Custom GPT → Actions surface (and via the upcoming MCP-native client). Configure the MCP endpoint:
{
"mcpServers": {
"weclapp": { "url": "https://your-anythingmcp-instance.com/mcp" }
}
}
For local development the URL is http://localhost:4000/mcp. Production use requires HTTPS so ChatGPT can reach the endpoint over the public internet.
Use Cases
- "Show all open sales orders" — order pipeline overview
- "Which invoices are overdue?" — payment-tracking dashboard
- "Look up customer Müller GmbH" — quick CRM lookup
- "What's the current stock of article A-1234?" — inventory check
- "List parties where
customerNumber-notnull=trueand createdDate this month" — new customer report
Pro Tip: ChatGPT and properties Filtering
ChatGPT's tool-call responses are billed by token. Always pass properties to limit the returned fields — for example properties=id,invoiceNumber,grossAmount,paid on weclapp_list_invoices keeps the per-row payload to a few hundred bytes instead of multi-KB JSON.
