Prosei MCP

A Model Context Protocol server that exposes your Prosei AI cases, documents, motions, and deadlines to Claude Desktop, Cursor, and any other MCP-compatible client.

Use it to ask Claude things like:

• "Pull the petition from my custody case and summarize the relief requested."
• "What deadlines do I have in the next 14 days across all my cases?"
• "Search my employment case for anything about the December 15 incident."
• "Show me the motion to dismiss I drafted last week."

Status

Phase 0 — read-only tools. Write tools (create motions, upload documents, add deadlines) are deliberately scoped out for the initial release.

Install

npm install -g @prosei-ai/mcp

Get an API key

1. Sign in at prosei.ai
2. Go to Settings → API Keys
3. Click Generate key, give it a name (e.g. "Claude Desktop"), copy the psk_live_... value

Keys scope to your user account and respect your subscription's usage limits.

Configure Claude Desktop

Edit your Claude Desktop config (~/Library/Application Support/Claude/claude_desktop_config.json on macOS, %APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "prosei": {
      "command": "npx",
      "args": ["-y", "@prosei-ai/mcp"],
      "env": {
        "PROSEI_API_KEY": "psk_live_..."
      }
    }
  }
}

Restart Claude Desktop. The Prosei tools will appear in the tools menu.
