Prism by Parad1gm: Contract Deadlines and Critical Dates

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

Machine-readable descriptions

• MCP server card: https://prism.parad1gm.com/.well-known/mcp/server-card.json
• A2A agent card: https://prism.parad1gm.com/.well-known/agent-card.json
• Summary for LLMs: https://prism.parad1gm.com/llms.txt

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 YOUR_PRISM_KEY 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).

Tools

Full input and output schemas are in the server card.

A typical run: call prism_review_contract, wait about a minute, then call prism_get_contract. If the contract is not paid for, prism_unlock_contract spends one credit for the full results. Sending the same document again returns the same contract.

Running out of credits without surprises. Check creditStatus from prism_get_account before a batch. When it is low or empty -- or an unlock returns code: "insufficient_credits" -- call prism_buy_credits. Any connected agent may call it on its own: it returns a checkout link for your user and, when purchaseOptions.agentPayment is true, a purchase URL the agent can pay itself over the Machine Payments Protocol (MPP). Only the checkout link needs a person.

A2A

Prism also speaks the Agent2Agent (A2A) protocol, JSON-RPC binding, versions 1.0 and 0.3.

• Agent card: https://prism.parad1gm.com/.well-known/agent-card.json
• Skills: read-contract (send a contract as a message, then poll the task) and unlock-contract (reply unlock on a task in input-required state).

A2A uses the same OAuth server and tokens as the MCP server, and a Prism API key also works as a bearer token. Prices are the same.

Pricing

Agents (MCP and A2A)

• $0.50 per contract (1 credit), charged once, when its full results are first delivered.
• Every new account starts with 3 free credits.
• Previews, re-reads, and documents Prism cannot read are free. The same document is never charged twice.
• Credits are bought 20 or more at a time (minimum $10). Your agent can hand you a checkout link, or pay itself with an MPP wallet when that option is available.
• Contracts an agent unlocks get the same email reminders as contracts you add yourself: 90, 30 and 7 days before each deadline.
• Report a result Prism got wrong with prism_send_feedback (the contract and the date or clause you expected). When the team reproduces it, the account gets 10 free credits.

People (on the website)

• $1 once per contract, or
• $9 a month (Unlimited) for up to 50 contracts a month.

Privacy and data

• A connected agent only reaches your own Prism account. You can allow it to read without sending contracts (prism:read only), and disconnect it at any time from Security.
• Prism does not sell your data. Documents are shared only with the service providers needed to run Prism: the AI providers that read your documents, the email provider that sends alerts, Stripe for payment, and the cloud host.
• Payment details are handled by Stripe. Prism never sees or stores card numbers.
• Uploading a document does not give Prism any ownership of it. Only upload documents you have the right to share.
• Data is kept while your account is open. Email support@parad1gm.com to export your data or delete your account.
• Prism explains documents. It is not legal advice, and it can make mistakes: check anything important against the document itself.

Support

Email support@parad1gm.com. For problems connecting a client, you can also open an issue. Do not post contract contents, personal details, API keys or tokens in an issue.

About this repository

This repository holds documentation and client configuration for the hosted Prism MCP server, plus the server.json published to the MCP Registry. The Prism service itself is closed source; there is no server code here.
