Htag Intelligence MCP server

HTAG Property Intelligence MCP

HTAG Property Intelligence MCP gives AI agents read-only access to Australian property intelligence: address standardisation, property summaries and estimates, sold/rented listing search, suburb/LGA market metrics, demographics, economics, geographic concordance, and H3 spatial layers.

This repository publishes the metadata for HTAG's public Model Context Protocol (MCP) servers - 70+ read-only public tools across three connectors - so they can be discovered, evaluated, and configured by AI clients, MCP directories, and integration partners.

What agents can do with this

• Standardise and enrich an address. Resolve free-text Australian addresses to canonical form, then pull property summary, demographics, and environment for that location.
• Estimate value and rent. Get current price and rent estimates for a property, plus market context (growth, scores, trends) for its suburb or LGA.
• Search comparable sales and rentals. Query sold and rented listings filtered by location, attributes, and time window to support comps and rental benchmarking.
• Profile a suburb, LGA, or postcode. Combine market metrics, demographics, census medians, and economic indicators (CPI, cash rate) for a single locality view.
• Reason over spatial layers. Pull H3 hex-indexed price/rent/yield surfaces, socio-environmental indicators, and risk layers; convert between H3 cells and administrative boundaries.
• Discover capabilities at runtime. List available MCP servers, tools, REST endpoints, and micro-agents via the public Docs connector - no credentials required.

Connectors

All connectors use Streamable HTTP transport.

HTAG Intelligence

Read-only property intelligence tools covering address standardisation, property summaries and estimates, sold/rented listing search, suburb and LGA market metrics, market trends, demographics, economics, and geographic concordance across HTAG's property dataset.

HTAG Spatial

Read-only H3 spatial tools for hex-indexed price, rent and yield surfaces, socio-environmental indicators, risk layers, H3 geometry and resolution utilities, and H3-to-administrative concordance.

HTAG Docs

Public capability-discovery connector for listing HTAG MCP servers and their tools, REST API endpoints and OpenAPI operations, and micro-agents. No authentication required.

Endpoints

All endpoints accept MCP requests over HTTPS using Streamable HTTP:

https://api.htagai.com/mcp/v1/servers/htag/mcp
https://api.htagai.com/mcp/v1/servers/htag-spatial/mcp
https://api.htagai.com/mcp/v1/servers/htag-docs/mcp

Authentication

• OAuth 2.0 - recommended for end-user / interactive agents. Authorization server metadata is discovered directly from each MCP URL; clients that support Dynamic Client Registration with authorization-code + PKCE can sign the user in without any pre-created OAuth client or API key.
• x-api-key header - optional alternate for server-to-server / headless agents. Issue keys from the Developer Portal and pass as a request header.
• Public - HTAG Docs requires no credentials.

Never commit API keys to client config files in source control. Store them in your client's secrets store or environment variables.
