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 accounts, signal domains, and buying 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.

Available Tools

The MCP server exposes the following tools that AI assistants can use. The tool set mirrors the public REST API, so new endpoints are added here over time.

getCompanies

List and filter accounts (companies) tracked in Rembrandt. Wraps GET /v1/accounts.

Use it for: "Show me the accounts we track", "Find accounts named Acme", "How many opportunities does account X have?"

Filters: accountId, companyName (contains match), limit, offset

The tool is named getCompanies for backwards compatibility; the underlying resource is an account (see the API Changelog).

getDomains

Get all signal domains configured for your organization. Wraps GET /v1/domains.

Use it for: "What domains do we track?", "List available signal domains"

Filters: limit, offset

Example Prompts

Once connected, you can ask your AI assistant:

  • "Show me the accounts we're tracking"

  • "Find accounts named Acme"

  • "Which accounts have the most open opportunities?"

  • "What signal domains do we track?"

For opportunity-level or signal-level questions, use the REST API directly through ChatGPT Actions or Microsoft Copilot Studio, which expose the full surface (accounts, opportunities, solutions, domains).

Security and Permissions

  • Your data is only accessible through authorized MCP connections

  • MCP provides read-only access to your organization's data

  • The connection is scoped to the organization you selected during authorization

  • You can revoke access at any time by re-authorizing with a new token
