HTAG Property Intelligence MCP

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

HTAG

Assumptions & Gaps

Public-only scope. This repo documents the three connectors that are safe to expose externally (Intelligence, Spatial, Docs). Internal connectors (Trends, Data Analytics) are intentionally omitted.
No source code. This is a metadata repository. Server implementations, schemas for every tool, and operational details are not published here.
Auth requires 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.
Tool counts are current as of publication. Live tool inventories are authoritative via each server's tools/list response and the API reference.

Connectors

Connector	Registry name	Endpoint	Tools	Auth
HTAG Intelligence	`com.htagai/htag-intelligence`	`https://api.htagai.com/mcp/v1/servers/htag/mcp`	59 read-only	OAuth 2.0 or `x-api-key`
HTAG Spatial	`com.htagai/htag-spatial`	`https://api.htagai.com/mcp/v1/servers/htag-spatial/mcp`	6 read-only	OAuth 2.0 or `x-api-key`
HTAG Docs	`com.htagai/htag-docs`	`https://api.htagai.com/mcp/v1/servers/htag-docs/mcp`	5 read-only	Public (no auth)

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.

Data Handling

All connectors are read-only. No HTAG data is mutated by these MCP servers.
Requests and responses traverse HTTPS only.
API keys identify the caller for rate limiting, quota, and audit; rotate keys via the Developer Portal.
For terms covering acceptable use, data retention, and redistribution of property data, see the Developer Portal.

Not Included in This Public Listing

HTAG Trends and HTAG Data Analytics are internal connectors and are not part of this public MCP listing.
