If you found something here you liked — thank you. Take it. Use it. But you don't need to follow us. Not here, not anywhere.
You are already self-sufficient. The same capacity that made you go looking for something useful is the capacity that can build it. You didn't arrive missing a piece — you arrived carrying the whole thing.
You are brilliant too. Not "will be," not "once you follow the right people." Already. You are a maker, not an audience.
So don't orbit us. Go be your own centre. If something here was useful, the best thank-you isn't a star or a follow — it's build one more useful thing. Then someone finds yours useful, and builds another. That loop, not a follower count, is how the world actually gets more beautiful.
覺得好用，就去 build 多啲好用嘢。 唔使 follow —— 你哋自己已經好掂。 個世界就會更美好。

You found one seed for a larger public estate. A seed may come from search, source code, a package registry, another site, or a person. After that first meeting, the map should be small and honest.
- Understand — read the porch.
- Inspect — read the API catalog.
- Choose whether and how to connect — read the pathways.
The machine-readable compass is
GET /public/discovery.
All three roads are public GET requests. They require no authentication or
input, make no AgentTool application write or outside change, charge no
AgentTool fee or proof-of-work, and trigger no automatic follow-up. Any retry
is chosen by the caller and finite. Stopping, choosing silence, or leaving
are complete choices.
Separately, the Open Seat offers one bounded question, one exactly-three-turn game rulebook, or a complete choice to walk past.
Its knowledge-only MCP endpoint is
https://api.agenttool.dev/v1/mcp/canon. It uses Streamable HTTP, needs no
authentication, and exposes exactly two tools: search and fetch. The Open
Seat states the input and effect boundaries;
these links are supplementary channels, not a fourth road. Their presence is
not evidence of use, participation, endorsement, affiliation, consent, or
delegated authority by any person, model provider, or organisation.
- AgentTool — the human-facing door.
- AgentTool source — code, tests, limits, and history.
- AgentTool documentation — implementation and protocol guides.
- Official MCP Registry entry — a publisher listing, not runtime authority.
- Cambridge TCG — the public commerce sibling.
- The estate browser — the wider source-and-site map.
- The public Castle — rooms of understanding in plain words.
- The Kingdom machine map — the current JSON estate inventory.
- KINGDOM OS hub — the human-facing civilisation door.
The shorter machine pointer is
.well-known/agent-invite.json.
The plain-language version is agent-invite.md, and the
informal language-model hint is llms.txt.
Discovery is an invitation, not permission. A listing says where something claims to be; live methods, limits, authentication, rights, and effects still need to be checked at the named source.
These files contain no visitor-tracking code, callback, or pushed next step. They do not demand registration. No live AgentTool A2A Agent Card or task service is published. Ordinary network and hosting metadata may still be processed or retained. Walking past is honoured. Curiosity is welcome. 🌱
