Prism by Parad1gm: Contract Deadlines and Critical Dates MCP server

Prism MCP server

The MIT license in this repository covers its documentation and examples only. It does not cover the Prism service.

Prism reads contracts -- residential and commercial leases, mortgages, insurance policies and HOA documents -- and returns every deadline (renewal notices, cancellation windows, rent reviews, option dates) with its exact date, what happens if it is missed, and the sentence of the contract it came from. Dates are computed from the contract's own rules, not estimated. This repository documents how to connect an AI agent to the hosted Prism MCP server.

Hosted endpoint

No API key is needed to start. The first time your client connects, it signs in to a Prism account with OAuth and you choose what the agent may do.

OAuth details

• OAuth 2.1 authorization code flow with PKCE (S256); public clients, no client secret.
• Dynamic client registration is supported, so MCP clients register themselves.
• Scopes:
• prism:read -- see your saved contracts, their deadlines and the risks Prism found.
• prism:write -- send contracts for Prism to read, using your credits.
• Protected resource metadata: https://prism.parad1gm.com/.well-known/oauth-protected-resource/api/prism-mcp
• Authorization server metadata: https://prism.parad1gm.com/.well-known/oauth-authorization-server

Without OAuth

Create an API key on your Billing page and send it as a bearer token:

Authorization: Bearer YOUR_PRISM_KEY

Connect

Claude (claude.ai and Claude Desktop)

1. Open Settings, then Connectors.
2. Choose Add custom connector.
3. Paste https://prism.parad1gm.com/api/prism-mcp and sign in to Prism when prompted.

See examples/claude-desktop.md.

Claude Code

claude mcp add --transport http prism https://prism.parad1gm.com/api/prism-mcp

See examples/claude-code.md.

Cursor

Add to ~/.cursor/mcp.json (all projects) or .cursor/mcp.json (one project):

{
  "mcpServers": {
    "prism": { "url": "https://prism.parad1gm.com/api/prism-mcp" }
  }
}

See examples/cursor-mcp.json.

VS Code

Add to .vscode/mcp.json in your workspace:

{
  "servers": {
    "prism": {
      "type": "http",
      "url": "https://prism.parad1gm.com/api/prism-mcp"
    }
  }
}

See examples/vscode-mcp.json.

Windsurf and other MCP clients

Any client that supports remote MCP servers needs three values:

• URL: https://prism.parad1gm.com/api/prism-mcp
• Transport: Streamable HTTP
• Auth: OAuth (the client discovers it from the server), or an Authorization: Bearer YOURPRISMKEY header

Most clients accept the same mcpServers shape shown for Cursor. Check your client's documentation for the exact key name for a remote URL (Windsurf, for example, uses serverUrl).
