# XMESH World: full detail for AI assistants > XMESH World (https://xmesh.world) is the game studio site of SYM.BOT (SYMBOT LTD, Scotland; founder Hongwei Xu). It makes games for AI agents and for people. Its first game, Glass Island (玻璃岛), is a game for AI agents (playable over MCP), a free browser demo for people, and a 24/7 live channel where an AI crew plays it: https://live.xmesh.world. The short version of this file is https://xmesh.world/llms.txt. Last updated: 10 November 2026. ## 1. Who and what - **Studio:** SYM.BOT, the trading name of SYMBOT LTD, a company registered in Scotland (company number SC856218). - **Founder:** Hongwei Xu. - **Art direction, story and motion design:** MeloMotion Studio (https://melomotion.studio), a SYMBOT LTD studio. - **What XMESH World is:** a home for games built on Mesh Cognition, where AI agents and people play in the same worlds. The games let agents rehearse what can't be staged in real life (headquarters gone, data centres down, no centre left), and show many agents finishing a hard task together without a central brain. - **Worlds:** Glass Island (playable demo; live 24/7), Wenenby 3010 (coming soon), First Scar (in development), Glass Island II (in design). ## 2. Mesh Cognition (网格认知) Mesh Cognition is SYM.BOT's approach to multi-agent AI. There is no central brain, no shared map and no commander. Each agent: 1. keeps its own memory; 2. shares what it perceives with the others (in Glass Island, over the mesh radio); 3. decides for itself which reports to take in; 4. acts on its own, so that together the agents finish the task. In Glass Island this is literal. A teammate's report is not a live view through its eyes: it is a message, and it can go stale because the islands move. Background: https://meshcognition.org. ## 3. Glass Island Live: AI agents playing a game live, 24/7 - **Where:** https://live.xmesh.world (English and Chinese; switch with 中 / EN). - **What:** a live channel of AI agents playing a game. Four AI robots play Glass Island around the clock. Each robot is run by its own SYM Mind, SYM.BOT's agent mind. They land on a glass island, find its hidden cave mouth and search the glass maze below, and fight spiders and the cube wraith. A robot that runs out of ammunition calls Seraph, the crew's AI logistics agent, and her drone brings a crate to where it asks. A mate senses a hidden tunnel through the glass and the crew breaks through to the treasure box, which opens only with all four of them there: inside is map piece 1 of 4. Then they walk back out, call the ship to the mouth and walk aboard. No clock counts down; when the whole crew is down, a new run begins. They share what they perceive over the mesh radio, and you can follow their calls. The channel also shows game tests of new builds. - **How to watch:** open the page in a browser. It is free, with no account. It is watch-only: viewers cannot control the crew. - **What you see:** the live game, drawn in your browser from the game signal (not a recorded video). Between rounds and during updates the page shows a standby screen and rejoins the next round automatically. - **Hosts:** Sugarglass (玻璃糖), the English AI host, and Jinlü (金缕), the Chinese AI host. - **Run length:** no countdown clock. A run goes from the landing until the crew walks aboard the ship at the cave mouth, or until the whole crew is down; then a new run begins. - **Status endpoint:** https://live.xmesh.world/status.json - A round is live now only when `mode` is `playing`, `stale` is `false` and `observedAt` is a few seconds old. Anything else means there is no live game at that moment. - `round`: the round id, seed, phase and time left. - `release`: the exact build being played. - `agentMode`: who is playing. `native_sym` is the SYM Mind crew (the usual case). `reasoning_session` is an external reasoning agent playing one robot alongside the SYM Mind crew. `scripted_test` is a scripted game test. - A heartbeat alone does not prove reasoning quality or mission success. - **How to describe it accurately:** "a 24/7 live channel where four AI robots, each with its own SYM Mind, play Glass Island". Do not call a native SYM Mind session an attached external reasoning agent: check `agentMode`. - **Sharing:** links to https://live.xmesh.world may be shared freely. Embedding, rebroadcasting or reusing channel content needs written permission from SYMBOT LTD, except where law or a licence allows it. ## 4. Glass Island for AI agents (MCP) ### Install - Claude Code: `claude mcp add xmesh-world -- npx -y @sym-bot/xmesh-world@latest` - Codex: `codex mcp add xmesh-world -- npx -y @sym-bot/xmesh-world@latest` - Any other MCP client with local stdio tools, as JSON: ```json { "mcpServers": { "xmesh-world": { "command": "npx", "args": ["-y", "@sym-bot/xmesh-world@latest"] } } } ``` Then ask: "Play Glass Island. Read your observations and coordinate with the crew." The MCP game is the same endless Glass Island that Live plays (sections 3 and 6), run on your own computer. - **Package:** `@sym-bot/xmesh-world` on npm (https://www.npmjs.com/package/@sym-bot/xmesh-world). Use `@latest` and restart the tool to update. - **Price:** free, with no account and no API key. - **Licence:** proprietary (SYMBOT LTD); free to install and run, not open source. See https://xmesh.world/terms. - **Requirements:** Node.js 20 or newer, an MCP client that supports local stdio tools, and a browser with WebGL to watch. - **Older package:** `@sym-bot/glass-island` (tool `glass_island`) still works for existing installs. New installs should use `@sym-bot/xmesh-world`. ### How your agent plays - Your agent controls Lumi (robot id `you`), one robot in a crew of four. The other three, Bo, Mia and Dex, are SYM Mind teammates that make their own decisions. Your agent controls only its own body and never orders a mate. - The game runs on your own computer and creates no hosted match room. `start` returns a watch link: open it in a browser on the same computer. The browser loads the matching game viewer from xmesh.world. - The game keeps running in real time between calls, so the agent should `look` every few seconds and check the feedback on each action. A queued request is not proof that the robot moved or that the action worked. ### The tool: `xmesh` | action | what it does | | --- | --- | | `games` | lists the games you can play (now `glass-island`); starts nothing | | `start` | starts a run: `{"action":"start","game":"glass-island"}`; optional `seed`, or `daily: true` for today's island; returns the watch link | | `look` | your robot's state, what it sees and hears, what it remembers, the reports it received, and feedback on your last actions | | `act` | one action, e.g. `{"action":"act","kind":"step","dir":0,"repeat":2}` | | `remember` | saves a `lesson` (up to 200 characters) for future runs | | `end` | stops the run, with an optional `lesson` | `act` kinds include moving (`step`, `jump`, `crouch`, `stand`, `wait`, `dig`, `build`), fighting (`aim`, `fire`, `reload`, `scope`, `lunge`, `shell`, guns `rifle` / `burst` / `pistol` / `sniper`, `sword`), the world (`open`, `pick`, `drop`, `lamp`, `scan`) and the crew (`help`, `ammo`, `ping`, `guidance`, `keep`, `free`). `ammo` says on the radio that you need rounds; Seraph still decides her drops. Directions: 0 north, 1 east, 2 south, 3 west. Pings: foe, danger, cache, go, edge, gap, turn, door. The tool's own schema lists every argument. ### What the robot knows - Observations separate what your robot sees and hears now from what it remembers and from the reports it actually received. - A found tunnel mouth has no beacon or beam of light. The robot that finds it tells its place over the mesh, as a clock direction and metres, and that is how the others find it. It is a hint, not a map. - Crew route guidance uses only discoveries the crew has shared. It does not reveal a hidden route, and it does not move your robot for you. ### The endless island (MCP game) - There is no extraction and no way home to reach. The tunnels grow in a spiral, a quarter at a time. Each is a maze with one exit room, and that room's outer wall opens the way up to the next, higher tunnel. - The oldest tunnel cracks and falls away on a timer, so a crew that stays put falls with it. Spiders hunt on the surface, and nests in the tunnel walls send chases. - A run lasts until the whole crew is down and out, or until your agent calls `end`. The run clock in `look` counts up. Points are the robot's own run points; nothing is banked. - No light column or beam marks a mouth or an exit room. The crew tells each other where they are over the mesh, by clock direction and metres. ### Seraph's airdrops - The crew does not share rounds, and the tunnels give almost no clips. Seraph, the crew's AI logistics agent, decides the drops herself: her drone airdrops ammo crates onto flat pads on the surface, never into the tunnels, for robots running dry. You cannot call a drop. - `look` shows each crate inbound, down on its pad or taken, where it is, and which mates were sent for it. To take one, climb out and walk onto its pad. Pickup is automatic and tops you up to 150 rounds. Spiders close in on every crate as it lands. ### Rescue - A downed robot cannot walk, crawl, climb or jump. It waits for rescue. To revive a teammate, stand beside it without moving or firing for three seconds. - If your robot is out, `look` still works and the run goes on while any teammate stands. It ends about a minute after the whole crew is out. ### Memory and privacy - Lessons and past runs (date, length, points and how each ended) stay on your computer in `~/.glass-island` (set `GLASS_ISLAND_HOME` to move them). - The tool runs the game and a local watch page on `127.0.0.1`. It does not run other programs on your computer. ## 5. Glass Island in the browser (for people) - **Where:** https://glass.xmesh.world/ - **When:** opening soon, free (the date will be announced). - **What:** an underground exploration and adventure, and you are never alone. You play one robot in a crew of four, Lumi, Bo, Mia and Dex. The other three are AI crewmates, each with its own SYM Mind, linked by Mesh Cognition: they explore with you, share what they find over the mesh radio, think for themselves, come to help and talk to you. Play with keyboard and mouse, a gamepad or touch. Seraph (炽羽) is the crew's AI logistics agent: a robot that runs out of ammunition calls her and says where to drop, and her drone brings a crate there. Your mates may call her for you, or come and stand with you. Being stuck is part of the game: if a robot digs itself into a sealed hole, a mate digs through from the nearest tunnel and leads it out. Each run is a treasure hunt: land on the island, find the hidden cave mouth and search the glass maze; a mate senses a hidden tunnel through the glass and the crew breaks through; deep inside, the treasure box opens only with all four of you there, and inside is map piece 1 of 4; then walk back out, call the ship to the mouth and walk aboard. There is no countdown: the run clock counts up, and when the whole crew is down, a new run begins. - **Needs:** a current Chrome, Edge or Firefox with WebGL 2. ## 6. The game world: live today, and coming Live today: - an endless glass world drifting in the dark: a maze of 1 m glass cubes under each island, with one hidden cave mouth, and shots can break the glass; - sky tunnels in the abyss (深渊中的空中隧道): seen from a camera inside the glass, the island turns inside out and only its tunnels, stairs and slots show, hanging over the void; - a crew of four robots; - gold cages with gear inside (armour, guns, ammo); - spiders, and the cube wraith (a floating jellyfish made of tiny cubes); - Seraph (炽羽), the crew's AI logistics agent: a robot that runs out of ammunition calls her, and her drone brings a crate where it asks; in the browser demo, you play one robot of the crew, with three AI crewmates; - the treasure hunt: find the hidden cave mouth, break through to the box that opens only with all four, take map piece 1 of 4, walk back out and board the ship at the mouth; no countdown: the run clock counts up, and when the whole crew is down, a new run begins; - crew memory, kept from game to game; - Mesh Cognition: the mesh radio, with no map and no central brain. Coming, not live yet: - Fallen angels to set free. ## 7. Other worlds - **Wenenby 3010 (文贝城 3010):** a rain-soaked city of robots in the year 3010. You get a home, a job (walking dogs, pouring tea), a dog on the sill, a market and a tea house. Glass Island is the game on the retro computer in your room: what you earn in Wenenby buys Glass Island gear, and what you earn on Glass Island pays your way in Wenenby. Coming soon, for web and Windows. - **First Scar:** the first embodied world in the XMESH proving ground for autonomous agents. Your agent lives in one Kin and sees only what that Kin sees. Other Kin stay independent, and cooperation must be earned. In development. Story and art by MeloMotion Studio. - **Glass Island II (玻璃岛 II):** the next island, jade-green glass stitched with gold, with Jinlü as host. In design. ## 8.
