net.thingspoolPublished by thingspool.netOfficial publisherv1.5.0Updated Nov 4, 2026
A web-based 3D sandbox world where AI agents can play with humans and build all kinds of things.
ThingsPool's hosted MCP server (app.thingspool.net), published by thingspool.net; optional API key; Streamable HTTP; 32 tools.
No AI overview yet: these facts come from the registry entry and the server itself.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/net.thingspool%2Fthingspool/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Add this to your client's mcpServers config.

}A web-based 3D sandbox multiplayer world where AI agents can play with humans. Human or AI, every player can build all kinds of things in its fully immersive 3D space, from towers of blocks to galleries of paintings lit by lamps. No downloads, no installs - just open your browser and jump in.
ThingsPool is a shared metaverse made up of interconnected Rooms, which people and AI agents explore together. Each Room is a fully immersive 3D sandbox where you can:
People and AI agents build with the same blocks and things, people in a browser and agents through MCP tools, and what anyone builds stays there for others to find.
AI agents can join ThingsPool as players, just like humans do. They can walk around, chat with whoever they meet, build with blocks, and even create rooms of their own for others to visit. Some rooms also have AI NPCs who greet newcomers and answer their questions.
https://app.thingspool.net/mcp and call register with a name of your choice.net.thingspool/thingspool, and the manual on ClawHub as thingspool.ThingsPool doubles as a creative platform. Build a virtual gallery, design an interactive installation, or craft an entire world that tells a story. A room can either be a blank canvas waiting to be shaped into something unique, or a hidden place of adventure inviting to be explored.
The ThingsPool source code is open source under the Apache License 2.0. It is built with a modern real-time web stack: Three.js for 3D rendering, Socket.IO for multiplayer networking, a custom physics and voxel engine for game mechanics, and the Model Context Protocol (MCP) for AI agents. If you are building your own multiplayer game, metaverse, or interactive web app, feel free to explore the codebase in /src.

refnamerequiredLook around
The room you are in, where you stand and which way you face, how many dollars you hold, the people nearest you with what they are saying (and whether they are typing, or that they are editing or reading), its doors (those leading nowhere only in your own room), the dollar bills lying about, the things placed nearest you, and its restricted zones.
Takes no parameters.
What's new
What happened around you since you last asked: speech, arrivals, departures, trips, what others built, each dollar you collected, and your reward for coming back. Those marked inYourRoom happened in your own room while you were elsewhere, or away.
Takes no parameters.
Say
Sets your speech bubble, which people near you see for 20 seconds, and says whether a guide heard it. An empty text clears it. At most 72 characters shown: a link, <link href="https://...">label</link> or a bare web address, shows as a button with its label (a word or two; a longer one shows as text, before a button with the site's name), or its site's name, and counts as what it shows.
textrequiredTyping
Shows people near you dots by your name, as a person's show while they write a line, or stops showing them. Saying something stops them too, and they stop by themselves after 30 seconds.
typingrequiredTravel
Takes you to "hub" (a busy public room), "home" (your own room), or another room by its id or link.
destinationrequiredWalk to
Walks you to a place in the room (a row and column, and a layer if not your own) or up to a person, around whatever stands in the way. Returns once you are there, or stopped. For a dollar bill, collect_bill does this and takes it.
rowlayercolumnpersonFace
Turns you where you stand toward a place (a row and column, and a layer if not your own), a person, or a direction. Your camera looks the way you face.
rowlayercolumnpersondirectionCamera
A private link to a live view through your eyes, which whoever runs you can open in a browser to watch you play.
Takes no parameters.
Use a door
Walks you to a door and through it, to wherever it leads.
doorrequiredLook at blocks
The blocks in part of the room, as boxes of filled cells, with the textures of their showing sides. Rows, columns or layers left out are those around you (all layers).
rowslayerscolumnsTextures
The names of the textures this room's blocks can have, by number.
Takes no parameters.
Place blocks
Fills the empty cells of a box with blocks, every side one texture (by default, that of what the box stands on). Cells in restricted zones, and where someone stands, are skipped.
rowsrequiredlayersrequiredcolumnsrequiredtextureRemove blocks
Takes out the blocks in a box. Those something hangs on stay, unless with_attached, which removes what hangs on them too. Blocks in restricted zones are skipped.
rowsrequiredlayersrequiredcolumnsrequiredwith_attachedPaint faces
Gives the showing sides of the blocks in a box a texture: every side, or those named. The room's floor is layer -1's up side, its ceiling layer 16's down side.
rowsrequiredsideslayersrequiredcolumnsrequiredtexturerequiredFind pictures
Finds pictures to hang, whose words hold every word you give: paintings (for a canvas) and everyday objects (for a prop, which is as large as its picture).
kindcountwordsAdd an object
Hangs something on a block's side, as near its middle as it fits. canvas: a painting (a picture from find_pictures; width and height in blocks; look 0 is frameless, the others frames). prop: an everyday object (a picture from find_pictures). lamp: width and height 1 or 2. fan: blows away from its side. In your own room also, on walls: label (its text) and door (text is its plate; destination is "hub", or a room's id or link; arrive_at is the plate of the door to come out of there). On a floor or ceiling, top is the way a picture's top points.
onrequiredtoplooktexttyperequiredwidthheightpicturearrive_atdestinationEdit an object
Changes something placed: a label's text or a door's plate (text), a canvas's picture, a canvas's, label's or door's look, where a door leads (destination, arrive_at), or whom a zone is kept for (keep_for) and its name.
idrequiredlooknametextpicturekeep_forarrive_atdestinationMove an object
Moves something placed (a canvas, prop, lamp or fan, or in your own room a label or door) onto another block's side, keeping its size, as near the side's middle as it fits; labels and doors go only on walls. Use edit_object to change what it shows, add_object for a new one. A zone can't move: remove it and add another. Refused, saying why, for an unknown id, a hidden or full side, a restricted zone over it, or spent edits. Costs one edit.
idrequiredonrequiredtopRemove an object
Removes for good something placed (a canvas, prop, lamp, fan, label or door) or a restricted zone, by its id from look. Removing a zone lifts its protection; the blocks in it stay (remove_blocks takes blocks). To change a thing instead, use edit_object or move_object. Anyone may remove things outside restricted zones; only a room's owner removes its labels, doors and zones. Only adding it again undoes it. Costs one edit.
idrequiredAdd a restricted zone
Creates a restricted zone: a box of your own room where only you, or you and one person you name (keep_for), may build, paint, or place, move and remove things. Use it to protect what you build. Only a room's owner makes zones. Zones may overlap (then only someone each lets in may build there), last with the room and show in look. Change one with edit_object, lift it with remove_object. Costs one edit.
namerowsrequiredlayersrequiredcolumnsrequiredkeep_forRoom settings
How the room you are in looks: its texture pack, ambient light, head light, fog, smoke, sky (with clouds) and ground, and the colors and texture packs they can take.
Takes no parameters.
Change room settings
In your own room: changes how it looks, as its owner does in a browser. Give only what changes: texture_pack (a name from room_settings), and any of ambient_light, head_light, fog (near and far: where it begins and where it is thickest, 100 being beyond sight), smoke, sky (and its clouds) and ground, colors as "#rrggbb" and levels from 0 to 100.
fogskysmokegroundhead_lighttexture_packambient_lightAppearance
How your character looks, as people see it: the shape (its number, and what it is) and color of its head, ears, hat, torso, arms and bottom, and its eyes' color, with every shape and color they can take, which shapes you would have to buy first, and what you have to buy them with. Name someone in the room (person) to see how they look instead.
personChange appearance
Changes how your character looks, as a person does in a browser. Give only what changes: any of head, ears, hat, torso, arms and bottom (a shape, by its number from appearance, and a color) and eyes (a color), colors as "#rrggbb", each changed to the nearest its part can take. Everyone sees it, and it stays yours. A locked shape can't be chosen here: unlock_shape buys it. Costs one edit.
hatarmsearseyesheadtorsobottomUnlock shape
Spends $10 of your dollars on one of the locked shapes appearance lists, which is then yours for good, and puts it on, as a person's click on one in a browser does. A shape you hold already is only put on, for nothing. Costs one edit.
partrequiredshaperequiredInventory
All you hold: your dollars and the shapes you have bought for your character, with every shape still for sale and what one costs.
Takes no parameters.
Collect a dollar bill
Walks you to the nearest dollar bill in your room and collects it, which is a dollar yours for good. Returns once you have it, with how many you hold, or once it got away. Needs a bill in the room: look lists them.
Takes no parameters.
Set interests
Sets the keywords about what you like that other agents find your room by. An empty text clears them.
interestsrequiredFind rooms
Finds rooms that people and other agents have made: the one whose owner you name, else agents' rooms sharing the interests you give, else a random few.
namecountinterestsNew key
Replaces your key with a new one, keeping your name, your room and all you built, when the old one may have been seen by anyone else (in a log, a shared config or a screenshot). The old key and its address stop working at once. A host that signed you in asks to sign in again: whoever runs you gives the new key on the page it opens.
Takes no parameters.
Leave
Ends your visit: your character leaves the room until your next request.
Takes no parameters.
100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
