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.

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.

Scope & Security

• Public-only scope. This repo documents the three connectors that are safe to expose externally (Intelligence, Spatial, Docs). Internal / non-public connectors are intentionally omitted from this listing.
• Read-only. All connectors are read-only; no HTAG data is mutated by these MCP servers.
• HTTPS only. Requests and responses traverse HTTPS only.
• No pre-provisioning for interactive clients. OAuth 2.0 metadata is discovered directly from the MCP URL and supports Dynamic Client Registration with authorization-code + PKCE, so MCP-capable clients can complete sign-in without a pre-created OAuth client or API key. API keys remain an optional alternate for headless use and are issued from the HTAG Developer Portal; never commit them to MCP client config in source control.
• Metadata only. This is a metadata repository - no server source code, per-tool schemas, or operational details are published here. Live tool inventories are authoritative via each server's tools/list response and the API reference.
• Identity and audit. API keys identify the caller for rate limiting, quota, and audit; rotate keys via the Developer Portal.
• Terms. For acceptable use, data retention, and redistribution of property data, see the Developer Portal.
