Propstack + ChatGPT
Propstack — the CRM German estate agents run on: properties, contacts, enquiries, activities, projects and saved searches. REST API v1, API-key auth.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
PROPSTACK_API_KEY
Step 1 — Get credentials
Getting a key
- Sign in to Propstack as an administrator and open Verwaltung → API-Schlüssel (crm.propstack.de/app/admin/api_keys).
- Create an API V1 key, give it the read permissions the agent needs, and put it in
PROPSTACK_API_KEY. The key carries the permissions set there — treat it as a password, because whoever holds it can read the whole customer base.
The key travels in an X-API-KEY header. No Bearer. (Propstack also accepts an api_key query parameter; this adapter does not use it, so the key stays out of URLs and logs.)
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in ChatGPT
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
ChatGPT adds MCP servers as plugins on its Plugins page, on the web and on paid plans. Developer mode is no longer needed. In a Business workspace only admins and owners can add one; in Enterprise and Edu an admin can grant the Create plugins with MCPs permission.
- Go to chatgpt.com/plugins, click Add, then Add custom MCP server.
- Enter a name, e.g. Name:
Propstack. - Under Connection, enter the Server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_IDand keep Authentication on OAuth. - Select I understand and want to continue, then Create as a plugin. When ChatGPT asks, sign in to AnythingMCP and allow access.
- Install the new plugin from your personal plugins, then type @ in a chat and pick it.
