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 5

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.

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.

Htag Docs — questions

Answers built from our own checks of this server.

What can Htag Docs do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_api_endpoint, list_api_endpoints, list_mcp_servers, list_mcp_tools, list_micro_agents. 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 api and mcp. 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 92 of 92 checks got a reply (100.0%), average response time 1040 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 with the file path 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 5 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 1040 ms on average, which is faster than 8% 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?

Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
