Use Propstack with AI via MCP
Propstack is built API-first – which is exactly what makes the AI connection straightforward. A community MCP server covers the interface with around 47 tools and runs as a lightweight container inside your CompanyGPT environment.
What is Propstack?
Propstack is a cloud CRM from Propstack GmbH in Hamburg, built for real estate professionals – brokerages, developers and family offices. It manages contacts, properties, projects and deals along the entire marketing process, backed by a documented REST API with webhooks.
For AI agents the API-first approach is the decisive point: because practically the whole data set is reachable through the interface, questions about pipeline, property status or matching prospects can be answered directly. Combining information across several properties and contacts becomes a conversation rather than an export exercise.

How to Connect Propstack to CompanyGPT
Propstack GmbH does not publish an MCP server. What is used is the community server ashev87/propstack-mcp, published as the npm package propstack-mcp-server, which exposes around 47 tools across the full Propstack API – from contacts and properties to deals and buyer matching.
The server is a lightweight Node process that we run as a container inside your CompanyGPT environment. Authentication uses a Propstack API key (PROPSTACK_API_KEY), which stays in your own cloud tenant. Since Propstack is a publicly reachable cloud service, regular internet access is sufficient – no additional network configuration is required.
As with every integration, your administrators in CompanyGPT decide via roles and groups who may use the Propstack access. The set of enabled tools can be narrowed as well, for instance if you want to allow read-only research. Alternatively, we can build the connection directly on the documented REST API.
Typical Use Cases
How AI agents in CompanyGPT work with Propstack
Review the pipeline in conversation
Management asks which deals are in the closing phase this quarter and where no activity has been documented for some time.
Prepare buyer matching
For a given property, sales has the stored contacts checked against the profile and receives a reasoned shortlist for outreach.
The property file at a glance
Ahead of the notary appointment, an agent summarizes the state of a property – parties involved, documented steps and open tasks.
Frequently Asked Questions
Propstack and AI – the most important answers
Is there an official Propstack MCP server?
No. What is available is the community server propstack-mcp-server, which works through the documented Propstack API and provides around 47 tools for contacts, properties, deals and buyer matching.
Where does the MCP server run?
As a lightweight Node container inside your CompanyGPT environment. The API key therefore stays in your own cloud tenant rather than with a third-party service.
Do we need any special network setup?
No. Propstack is a cloud service and the container addresses the API directly over the internet. All you need is a valid API key from your Propstack account.
How is access restricted?
Through the permissions of the API key used and the tools enabled in CompanyGPT. Your administrators additionally decide by role and group which teams see the integration at all.
Can the assistant create records in Propstack?
The server covers the API broadly, so write tools are possible in principle. Whether and which of them are enabled is your decision – we recommend starting with research and analysis without write access.
