MCP Integration Guide

Connect Rembrandt to AI assistants using the Model Context Protocol (MCP) to access your market intelligence data directly in conversations.

Overview

The Model Context Protocol (MCP) allows AI assistants like Claude and ChatGPT to access your Rembrandt data through a standardized protocol. Once connected, you can ask questions about your prospects, companies, buying signals, and opportunities in natural language.

Authentication

MCP connections use OAuth-style authorization:

  1. Open the MCP setup flow for your AI assistant (see the specific guide for Claude or ChatGPT)

  2. You'll be redirected to Rembrandt to sign in and authorize the connection

  3. After authorization, you'll receive a code or token to configure in your AI assistant

The authorization is tied to your Rembrandt account and organization. Your AI assistant will only be able to access data from the organization you had selected when you authorized.
