Revalidata MCP server

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

Revalidata reads contracts and lists the deadlines in them: the date, what happens if it is missed, and the passage of the contract it was read from where one was captured. It reads residential and commercial leases, mortgages, insurance policies, HOA documents, purchase and sale agreements, construction contracts, loan modifications and vendor agreements. Dates are computed from the contract's own rules, not estimated. It can miss dates; how often is measured and published at revalidata.com/accuracy.

This repository documents how to connect an AI agent to the hosted Revalidata MCP server. Revalidata is a product of Built AI, Inc.

Hosted endpoint

No API key is needed to start. The first time your client connects, it signs in to a Revalidata 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 Revalidata found.

  • prism:write: send contracts for Revalidata to read, using your credits.

• Protected resource metadata: https://revalidata.com/.well-known/oauth-protected-resource/mcp

• Authorization server metadata: https://revalidata.com/.well-known/oauth-authorization-server

Without OAuth

Create an API key on your Billing page after you sign in, and send it as a bearer token:

Authorization: Bearer YOUR_REVALIDATA_KEY

Machine-readable descriptions

• MCP server card: https://revalidata.com/.well-known/mcp/server-card.json

• A2A agent card: https://revalidata.com/.well-known/agent-card.json

• Summary for LLMs: https://revalidata.com/llms.txt

Connect

Claude (claude.ai and Claude Desktop)

Find Revalidata Contracts in Claude's connector directory and connect it, or add it yourself:

1. Open Settings, then Connectors.

2. Choose Add custom connector.

3. Paste https://revalidata.com/mcp and sign in to Revalidata when prompted.

See examples/claude-desktop.md.

Claude Code

claude mcp add --transport http revalidata https://revalidata.com/mcp

See examples/claude-code.md.

Cursor

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

{
  "mcpServers": {
    "revalidata": { "url": "https://revalidata.com/mcp" }
  }
}

See examples/cursor-mcp.json.

VS Code

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

{
  "servers": {
    "revalidata": {
      "type": "http",
      "url": "https://revalidata.com/mcp"
    }
  }
}

See examples/vscode-mcp.json.

Windsurf and other MCP clients

Any client that supports remote MCP servers needs three values:

• URL: https://revalidata.com/mcp

• Transport: Streamable HTTP

• Auth: OAuth (the client discovers it from the server), or an Authorization: Bearer YOUR_REVALIDATA_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).

Connected before? The former addresses, https://revalidata.com/api/prism-mcp and https://prism.parad1gm.com/api/prism-mcp, still work, so nothing you set up earlier breaks. New setups should use https://revalidata.com/mcp.

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, with your user's agreement.

Running out of credits. Check creditStatus from prism_get_account before a batch. When it is low or empty, or an unlock returns code: "insufficient_credits", ask your user, then call prism_buy_credits for a checkout link they pay on themselves.

A2A

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

• Agent card: https://revalidata.com/.well-known/agent-card.json

• Skills: read-contract (send a contract as a message, then poll the task), unlock-contract (reply unlock on a task in input-required state) and send-feedback.

A2A uses the same OAuth server and tokens as the MCP server, and a Revalidata 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 Revalidata cannot read are free. The same document is never charged twice.

• Credits are bought 20 or more at a time (minimum $10) through a checkout link your user pays on.

• Contracts an agent unlocks get the same email reminders as contracts you add yourself: 90, 30 and 7 days before each deadline.

People (on the website)

• $1 once per contract,

• $9 a month (Unlimited) for up to 50 contracts a month, or

• $49 a month on the property-manager plan, for 5 people and up to 1,000 contracts a month.

Privacy and data

• A connected agent only reaches your own Revalidata account. You can allow it to read without sending contracts (prism:read only), and disconnect it at any time from Security in your Revalidata account.

• Revalidata does not sell your data. Documents are shared only with the service providers needed to run it: 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. Revalidata never sees or stores card numbers.

• Uploading a document does not give Revalidata any ownership of it. Only upload documents you have the right to share.

• Data is kept while your account is open. Email support@revalidata.com to export your data or delete your account.

• Revalidata explains documents. It is not legal advice, and it can make mistakes: check anything important against the document itself.

Read the full Privacy policy and Terms. Revalidata is operated by Built AI, Inc.

Support

Email support@revalidata.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 Revalidata MCP server, plus the server.json published to the MCP Registry as com.revalidata/contracts. The tool names keep their original prism_ prefix so existing integrations keep working. The Revalidata service itself is closed source; there is no server code here.
