Nothing serious here today

Today is the operative word: we check Htag Docs every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

api

get_api_endpoint

Return the full OpenAPI operation for one HTAG REST endpoint — parameters, requestBody, responses, examples. Use this BEFORE recommending an endpoint so your parameter hints match the live spec. Returns null if the endpoint is not in the catalogue.

list_api_endpoints

List HTAG public REST endpoints. Optional `tag` (e.g. 'Markets', 'Property', 'Spatial') and `query` (substring against path / summary) filters. Returns path, method, operationId, tags, and summary for each match.

mcp

list_mcp_servers

List every MCP server HTAG currently exposes. Each entry includes the server name, a short description, its mount path, and whether it is public (no auth required).

list_mcp_tools

List every tool registered on a named MCP server. Use `list_mcp_servers` first to discover server names. Each entry includes the tool name, its description, and the JSON-Schema input.

guide

get_guide

Return the full markdown of one HtAG agent guide: 'calling-htag' (call order, cost rules, paging, address keys, property types; read it first), 'costs' (billing units, rates, billing headers) or 'core-concepts' (place lookup, address keys and key spaces, levels, dates, null handling). The same content is served as the guide://<name> resources.

guides

list_guides

List the HtAG agent guides: name, uri, title, summary, updated date and source URL. Read 'calling-htag' with `get_guide` before planning HtAG data calls.

micro

list_micro_agents

List every callable HTAG micro-agent — turnkey agents that compose endpoint chains and apply HTAG methodology. Examples: 'suburb-analysis', 'suburb-comparison', 'comprehensive-dd'. Useful when a use case is best served by an existing agent rather than raw endpoint composition.

pricing

get_pricing

The HtAG data API rate card: list AUD per unit for each tier (Reference, Standard, Enhanced, Premium, Restricted) and each monthly volume band, linked-plan multipliers, the free allowance and an as-of date, plus how to read the `billing` receipt on htag tool results. Use it to estimate a call before making it: units x rate x plan multiplier. Also served as pricing://rate-card.

Htag Docs — questions

Answers built from our own checks of this server.

What can Htag Docs do?

It exposes 8 tools, read directly from the server on our last check. Among them: get_api_endpoint, get_guide, get_pricing, list_api_endpoints, list_guides, list_mcp_servers and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is Htag Docs mostly used for?

Its tools cluster around mcp and api. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is Htag Docs working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 1007 ms. The bar chart above shows every period we have measured.

How do I connect Htag Docs?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Htag Docs need an API key?

No. Htag Docs completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Htag Docs?

It answers our handshake in 1007 ms on average, which is faster than 6% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Htag Docs open source?

The code is open source: it is published under the MIT licence and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at api.htagai.com, which runs on its operator's own terms.
