How to Use the NCREIF Custom Query MCP in Claude Code

Q: What is the command to install NCREIF Custom Query MCP Server in Claude Code?

Run claude mcp add --transport http ncreif-custom-query-mcp -- . Make sure you put all flags before the server name. Verify the connection with claude mcp list.

Q: Privacy - How does the CLI handle authentication for institutional real estate data?

You only need one endpoint token configured in your /.claude.json file. The ephemeral V8 Isolate Sandbox handles the actual authentication with the NCREIF API, keeping your credentials isolated from the raw index data stream.

Claude Code executes headless NCREIF MCP Server data pulls straight from your terminal to update your property models.

Terminal-native index retrieval with Claude Code

SREs and backend developers do not want to open a browser to check real estate benchmarks. You can run a simple CLI command and the agent triggers `get_historical_npi` right in your terminal. The raw data streams back into your shell environment where you can pipe it into jq or redirect it to a local log file. It turns manual data gathering into a fast command-line operation.

Automated KPI syncing in CI/CD

You can embed this MCP Server into your GitHub Actions or cron jobs. When your nightly pipeline runs, the agent hits `get_predefined_kpi` to fetch the latest institutional metrics. The script then commits the updated figures to your repository or pushes them to your production database. Your valuation models always wake up to fresh benchmarks without human intervention.

Headless custom queries

Sometimes a standard index pull fails your specific audit requirements. You can pass a shell script to the agent that triggers `execute_query` with exact SQL-like parameters for your target property sector using this MCP Server. The database processes the custom request and returns the granular data back to your headless environment. You get exact market slices delivered directly to your backend infrastructure.
