Perplexity

Run custom queries via this MCP Server.

Your agent uses `execute_query` to run SQL-like commands against the NCREIF database directly from your chat window. You ask for regional office sector returns, and it pulls the exact rows you need. You don't log into a separate web portal. You don't download CSVs to your desktop. The tool handles the syntax and pagination automatically. You get raw data formatted exactly how you asked for it. This cuts out the usual manual filtering steps completely.

Pull decades of property performance.

The numbers don't lie when you pull real market data. The `get_historical_npi` tool fetches National Property Index returns across any timeframe. You tell Claude the start and end years. It returns the quarterly yields, appreciation, and income returns for that exact period. Analysts usually spend hours compiling these historical tables. Now your client grabs the numbers in seconds. You can ask it to calculate standard deviations or compare specific quarters right after the data loads.

Fetch standard metrics instantly.

When you need standard benchmarks fast, `get_predefined_kpi` pulls the exact figures. It targets specific preset indicators like rolling four-quarter returns or current capitalization rates. You skip the custom query building entirely. These MCP tools drop straight into your conversation context. Claude can then drop them into an investment memo or a comparative analysis. The data is always current with the latest NCREIF release.

Common questions about NCREIF Custom Query MCP in Claude Desktop

Open your developer settings and edit the configuration JSON file. Add the server command under the mcpServers key. Save the file and completely restart the application.

Yes. The agent routes requests to the correct endpoint based on your prompt. It will mix index data with your local files if you ask it to.

You can write standard SQL-like filters targeting specific property types, regions, and date ranges. The system translates these into API requests for the NCREIF backend.

You probably have a typo in your config file. Check the path to your executable. Verify that your authentication token is valid and active.

Your client processes historical NPI returns and regional property yields purely in memory. The connection uses an ephemeral V8 Isolate Sandbox. Vinkius destroys the environment the moment your session ends.
