MCP server for real estate, land and infrastructure data

Korzy is an MCP server for real estate and land data: it gives an AI assistant tools that look up real parcel and infrastructure records, so its answers about a place come from data rather than memory.

AI agents: the job to be done

Language models answer questions about specific properties from whatever they saw in training, which is rarely the current record. Agents that research land, energy or real estate need tools that return the record itself: the parcel at an address, the utilities at a point, the projects nearby.

The Korzy MCP server exposes those lookups as tools any MCP client can call. The plugin for Claude Code and Codex adds a research skill that chains them: address search, parcel record, then site context.

Questions Korzy answers for AI agents

Who owns this property and when did it last sell? (owner fields where published)
Does this address have public water and sewer?
What data-center projects are planned near this site?
What generation and grid capacity are in this region?

API routes and MCP tools for AI agents

Each lookup is a REST route and, where named, a tool on the Korzy MCP server. Routes link to their section of the API reference; credits and rate limits covers what each request costs.

MCP tool	REST route	What it returns
`search_parcels`	`/api/search`	Parcels at an address.
`get_parcel`	`/api/parcel-record`	One parcel’s attributes and a map link.
`get_site_context`	`/api/query/point`	Parcels, water and sewer service, treatment plants and data-center projects at a point.
`get_environment_context`	`/api/environment/context`	Environmental layers at a point and nearby cleanup sites.
`get_logistics_context`	`/api/logistics/context`	Nearby transport and logistics features.
`list_datasets`	`/api/query/catalog`	Coverage, source dates and query limits, so the agent knows what exists before it spends credits.

Example requests and production responses

Real responses from the production API, captured November 5, 2026 and trimmed to the main fields. Every request needs an API key; see API authentication.

1. search_parcels with owner fields

The tool call an agent makes for “Who owns 1600 Glenarm Pl, Denver?”, and the first record returned. Owner values are placeholders. 2 credits.
