Its built-in MCP server gives agents direct access to the same work.\n\nRun it on a laptop for one developer. Deploy it for a private team on Cloudflare, one server, Kubernetes, AWS, or Google Cloud.\n\n[Why Artifact Server](#why-artifact-server)[Built for AI agents and team collaboration](#built-for-ai-agents-and-team-collaboration)[Cloudflare and Artifact Server](#cloudflare-and-artifact-server)[Deploy it for a team](#deploy-it-for-a-team)[Run it locally](#run-it-locally)[Usage](#usage)[Security model](#security-model)[Development and project records](#development-and-project-records)\n\nTeams now use HTML, images, and video for plans, mockups, prototypes, code reviews, and other work created during product development. That work quickly becomes disorganized, and providers try to lock it inside their platforms.\n\nArtifact Server gives teams a self-hosted place to organize and collaborate on that work. Store artifacts by project, share them, comment on them, and keep control of the files and data.\n\nArtifact Server includes a built-in MCP server and a portable Agent Skill. Agents publish and update versioned artifacts. Teams review, comment on, and share the same work.\n\nConnect the agent and install the skill:\n\n```\nartifactserver connect\nnpx skills add plannotator/artifact-server\n```\n\nThen ask:\n\n```\n/artifact-server upload that HTML design doc\n```\n\nThe agent returns the full-screen review link first. [Read the MCP guide](/plannotator/artifact-server/blob/main/docs/mcp.md) for source checkouts, remote servers, permissions, and supported operations.\n\nLive session delivery is available from source for Pi and Claude Code Channels. Claude Channels require its research-preview development flag and, on managed plans, the organization policy. The OpenCode adapter is not release-qualified; live-host verification and contributions are welcome.\n\nCloudflare is the main hosted deployment target. Cloudflare Artifacts can add private Git-backed history for selected projects. It is off by default and currently requires closed beta access.\n\n[Deploy Artifact Server on Cloudflare](/plannotator/artifact-server/blob/main/deploy/cloudflare/README.md)[Configure optional Git history](/plannotator/artifact-server/blob/main/docs/cloudflare-artifacts.md)[Read the Cloudflare Artifacts documentation](https://developers.cloudflare.com/artifacts/)\n\nCloudflare is optional. Artifact Server also runs locally, on Compose, on Kubernetes, on AWS, and on Google Cloud.\n\nEvery remote deployment uses one trusted application origin and one isolated wildcard content domain.\n\n| Deployment | Data layer | Guide |\n|---|---|---|\n| Cloudflare | D1 and R2 |\n|\n\n[Compose guide](/plannotator/artifact-server/blob/main/packaging/compose/README.md)[Compose guide](/plannotator/artifact-server/blob/main/packaging/compose/README.md)[Helm guide](/plannotator/artifact-server/blob/main/packaging/helm/artifact-server/README.md)[AWS Pulumi guide](/plannotator/artifact-server/blob/main/deploy/pulumi/aws/README.md)[Google Cloud Pulumi guide](/plannotator/artifact-server/blob/main/deploy/pulumi/gcp/README.md)Azure teams deploy through the Helm chart on AKS; there is no separate Azure installer. Azure Blob Storage is available as a preview adapter and has not passed live Azure qualification.\n\n[Read the deployment guide](/plannotator/artifact-server/blob/main/docs/deployment.md) for shared requirements, storage choices, authentication, and backups.\n\nLocal mode stores metadata in SQLite and files on disk. It grants owner access only from the same loopback origin. Running from source requires Node.js 24.12 or newer and pnpm 10.34.3.\n\n```\ngit clone https://github.com/plannotator/artifact-server.git\ncd artifact-server\npnpm install\npnpm dev\n```\n\nOpen the printed URL. Public package download and verification commands will be added on release day. See [Get started locally](https://artifactserver.com/docs/get-started/) for the current source-development path.\n\nMost artifacts are published by an agent through the [Artifact Server Skill](/plannotator/artifact-server/blob/main/skills/artifact-server/SKILL.md) or [MCP](/plannotator/artifact-server/blob/main/docs/mcp.md). For direct access, use the `artifactserver`\n\nCLI to publish files and directories, connect to remote servers, and create new versions. [Read the CLI guide](/plannotator/artifact-server/blob/main/docs/cli.md).\n\nArtifact Server serves untrusted artifact content from isolated version hosts, separate from the trusted application origin used for authentication, review, comments, API, and MCP. Private content uses version-scoped browser sessions, and untrusted paths cannot select storage locations.\n\nRead the [security model](/plannotator/artifact-server/blob/main/project/spec/decisions/0002-shared-identity-and-private-content.md) or [report a vulnerability](/plannotator/artifact-server/blob/main/SECURITY.md).\n\nRead about Artifact Server's [software supply-chain security](https://artifactserver.com/docs/security/).\n\nInstall dependencies and run the focused development checks:\n\n```\npnpm install\npnpm check\npnpm test:web\n```\n\nRun the complete iteration gate before a handoff:\n\n```\npnpm verify:iteration\n```\n\nRepository engineering rules live in [AGENTS.md](/plannotator/artifact-server/blob/main/AGENTS.md).\n\nThe [ project](/plannotator/artifact-server/blob/main/project) directory contains specifications, conformance evidence, performance records, prototypes, and research.
