MCP server for Prismism — shareable links for any file.

Upload files and get tracked, shareable links directly from Claude Desktop, Cursor, Copilot, Windsurf, or any MCP-compatible agent.

Quick Start

1. Get an API key

Create a free account at prismism.dev or use the prismism_register tool after setup.

2. Add to your MCP config

Claude Desktop

Edit ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "prismism": {
      "command": "npx",
      "args": ["@prismism/mcp-server"],
      "env": {
        "PRISMISM_API_KEY": "pal_your_key_here"
      }
    }
  }
}

Cursor

Edit .cursor/mcp.json in your project root:

{
  "mcpServers": {
    "prismism": {
      "command": "npx",
      "args": ["@prismism/mcp-server"],
      "env": {
        "PRISMISM_API_KEY": "pal_your_key_here"
      }
    }
  }
}

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "prismism": {
      "command": "npx",
      "args": ["@prismism/mcp-server"],
      "env": {
        "PRISMISM_API_KEY": "pal_your_key_here"
      }
    }
  }
}

3. Verify it works

Ask your agent: "Use the prismism_health tool to check the connection"

Tools

Publishing files

"Publish this report as a shareable link"

The prismism_publish tool accepts:

• Plain text (default): HTML, Markdown, CSV, JSON, etc.
• Base64: Set encoding: "base64" for binary files like PDFs, images, and video

Supported formats: PDF, HTML, Markdown, Images (PNG/JPG/GIF/SVG/WebP), Video (MP4).

Registering without a key

If you don't have an API key yet, the prismism_register tool can create an account:

"Register me on Prismism with my email"

It returns the API key once — the agent will help you save it to your config.

Environment Variables

Variable	Required	Default	Description
PRISMISM_API_KEY	For most tools	—	Your Prismism API key
PRISMISM_BASE_URL	No	https://prismism.dev	API base URL

All tools return a consistent JSON envelope:

{
  "ok": true,
  "data": { ... },
  "_hints": ["Actionable guidance for the agent"]
}

On error:

{
  "ok": false,
  "error": { "code": "STORAGE_LIMIT", "message": "..." },
  "_hints": ["Upgrade at https://prismism.dev/settings/billing"]
}
