Artifacta MCP Server

![npm](https://www.npmjs.com/package/@artifacta-mcp/mcp) ![PyPI](https://pypi.org/project/artifacta-mcp/) ![License: MIT](./LICENSE)

Official MCP server for Artifacta — an artifact store purpose-built for AI agents. Agents persist run outputs (files, reports, datasets, build results) with session and agent metadata, hand them off across sessions, and share them via expiring download links. Content-hash dedup means re-storing the same bytes is free.

Listed in the official MCP registry as io.artifacta/mcp.

Two implementations with the same tool surface, error contract, and path-confinement engine:

| Directory | Package | Runtime | |-----------|---------|---------| | typescript/ | @artifacta-mcp/mcp | Node 20+ | | python/ | artifacta-mcp | Python 3.10+ |

Quick start

The fastest way to connect is the hosted server — no install, no API key:

claude mcp add --transport http artifacta https://mcp.artifacta.io/mcp

On first use your client self-registers via OAuth Dynamic Client Registration (PKCE) and opens a browser to authorize — no ak_live_ key to copy or store. See the hosted setup guide.

Local / CI (stdio)

For headless, air-gapped, or CI environments where a browser OAuth flow isn't available, run the package locally over stdio with an API key. Get a key at app.artifacta.io/dashboard/keys, then add to your MCP client config (Claude Desktop, Claude Code, Cursor, or any MCP client):

{
  "mcpServers": {
    "artifacta": {
      "command": "npx",
      "args": ["-y", "@artifacta-mcp/mcp"],
      "env": {
        "ARTIFACTA_API_KEY": "ak_live_..."
      }
    }
  }
}

Or run the Python implementation with pipx run artifacta-mcp.

See the per-package READMEs for config-file profiles, path confinement (--allow-path), destructive-tool gating (--allow-destructive), and troubleshooting: TypeScript · Python.

Tools

| Tool | Description | |------|-------------| | whoami | Verify credentials; returns tenant and plan info | | store_artifact | Upload an artifact from inline content or a local path | | request_upload_url / complete_upload | Two-phase presigned upload for large files | | get_artifact | Fetch artifact metadata by ID | | get_artifact_download_url | Get a presigned download URL (1h expiry) | | list_artifacts | List/filter artifacts by session, agent, or metadata | | list_sessions | List active sessions | | seal_session | Seal a session so no further artifacts can be added | | create_download_link | Create a public expiring share link (gated behind --allow-destructive) | | delete_artifact | Soft-delete an artifact (gated behind write confirmation) |

Plus MCP resources for whoami, artifact metadata, artifact bytes, and sessions.

Safety defaults: local-file uploads are confined to an explicit --allow-path allow-list, and destructive tools (public share links, deletes, session seals) are hidden from clients that can't confirm writes unless --allow-destructive is passed.

Framework integrations

The Python package ships optional adapters for OpenAI Agents SDK (pip install 'artifacta-mcp[openai-agents]') and LangChain/LangGraph (pip install 'artifacta-mcp[langchain]').
