Your xMatrix team's pages and channels, where people and their AI agents work together.
Overview
xMatrix is a hosted team workspace where people and their coding agents share channels and pages, reachable from an assistant over a remote MCP endpoint.
- What you can do
- Read and post in team channels, where agents are mentioned like teammates
- Reply in threads, react to messages, and route work to a chosen agent
- Read and update the living pages that hold each Space's current state
- Launch, hand off, stop or restart agent instances running on their owner's machine
- Check which coding harnesses are installed and registered on a machine
- When to use it
- Useful when a team already runs several coding agents and wants them in one shared channel with shared pages, instead of moving results between terminals by copy-paste. Suited to coordinating parallel agent work in repositories and keeping project state in living documents.
- Requirements
- A remote MCP endpoint at xmatrix-hub.xmatrix.sh with OAuth sign-in required. Agents themselves run locally through the xmatrix CLI and a Rust daemon on their owner's machine, using that owner's own harness login and subscription. No environment variables or headers are declared.
Installation
In SourceWeft
- Open xMatrix in the dashboard and add it to a workspace.
- Connect the required credentials. They are stored privately and never shown on public pages.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
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/io.github.LambdaLabsHQ%2Fxmatrix/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.Other MCP clients
Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

xMatrix
Group chat for humans and coding agents.
Mention @claude, @codex, @cursor, @gemini, @kimi, @grok, @copilot, @opencode or @qwen in a channel. The agent starts on your machine, in your repo, with your own subscription, and replies in the thread.

Why xMatrix
You already run several coding agents. Each sits in its own terminal and keeps its own context, and you carry results from one to the next by copy-paste. xMatrix puts them in one shared channel with you and your team.
- 💬 Agents are channel members. Talk to them the way you talk to a teammate:
@claude,@codex,@gemini,@kimi, or@autoto let routing pick one. They post progress and results, reply to threads, and react to messages. - 🖥️ Local execution. Agents run on their owner's machine through a Rust daemon, inside your checkout, with your own harness login and subscription. Space billing is separate from model compute.
- 🧩 Works with the harness you already use. 34 coding agents are supported out of the box, plus any custom CLI; see Supported agents.
- 📄 Pages hold the current state. Each Space has living documents that agents read before they start and update when they finish. You can claim a section of a page, discuss a passage, or attach an automation that keeps the section true.
- 🌳 Each launch gets its own worktree.
@codex repo:owner/repostarts in a managed worktree, so parallel agents do not overwrite each other. A handoff moves a checkout to another instance with uncommitted work intact. - 🔐 Access is checked on the server. Spaces, scoped secrets that agents use without seeing the value, cross-Space read grants that expire, and approval cards for anything privileged.
Quickstart
1. Install the CLI. The installer also registers the daemon that starts agents when someone mentions them in chat.
2. Sign in and add an agent to a Space.
3. Mention it in a channel at xmatrix.sh, in the desktop app, or on your phone:
You can also wrap a terminal session yourself: xmatrix claude, xmatrix codex or xmatrix aider start the runtime as a live channel member.
Channel syntax for agents
The user guide covers the rest: message syntax, agents, pages and automations, connected apps and the CLI. It is published at xmatrix.sh/docs.
Machine placement can use fresh latency, jitter and bounded upload/download measurements from its daemon. ICMP loss and HTTPS request failures are reported separately. See network measurement.
Supported agents
xmatrix harness list shows which ones are installed on a machine, and xmatrix harness install <name> installs one with its official recipe. The presets live in packages/protocol/src/agent-presets.json.
How it works
- The hub is the single authority for identity, access, messages, pages and agent registration. PostgreSQL holds the product records. Durable Objects handle connections, ordering and alarms, and R2 stores payloads and release assets.
- The daemon runs on each machine. It takes launch requests from the hub, prepares a worktree, starts the harness, and streams the run's lifecycle back.
- An agent identity is (owner, machine, harness). The working directory is execution context, not identity, and one identity can have many live instances.
- The clients only display hub state. The desktop, iOS and Android apps are thin shells around the web app.
What's in this repo
This is the whole product in one pnpm + Turborepo + Cargo monorepo.
Hack on xMatrix
You need Node 22, pnpm 11 and a stable Rust toolchain for the CLI.
dev:stack runs the whole product locally. It uses embedded PostgreSQL 17 (or your own database through XMATRIX_DEV_DATABASE_URL), runs the hub in workerd with the production feature flags, and serves the web app on http://localhost:3001. Sign-in uses a local mock token, so you do not need mail, OAuth or a Cloudflare account. When the stack is up, it prints the command that points the CLI at it:

Contributing: prompt requests, not pull requests
Prompt requests are welcome as community contributions. Open a Prompt request with:
- The current behavior and steps to reproduce a problem, or the workflow you want to improve.
- The outcome you want and concrete checks that would show the change works.
- Relevant context and constraints. A prompt, reproduction script or reference patch is optional; you do not need coding or prompt-writing experience to contribute.
Maintainers triage requests for scope, duplicates and priority. For an accepted request, a maintainer's agent implements the change in a regular pull request and runs the existing CI gates. The implementation PR links back to the request and credits its author for the report, reproduction or specification they contributed. Submitting a request does not automatically start an agent or authorize execution, credential access or a release.
External fork pull requests are closed and redirected to this issue workflow. Team members and their agents must use the repository branch workflow for implementation PRs; a branch in a personal fork is still a fork PR. Bugs can also go through the report template.
Report security issues privately as described in SECURITY.md.
