# MCP Server

> Add Orthogonal to Claude, Cursor, or any MCP-compatible tool

The Orthogonal MCP server lets AI assistants discover and use APIs directly. Your AI can search for APIs, understand their parameters, and make calls - all through natural conversation.

## What is MCP?

[Model Context Protocol (MCP)](https://modelcontextprotocol.io) is an open standard for connecting AI assistants to external tools and data sources. When you add Orthogonal as an MCP server, your AI gains access to paid APIs.

## Available Tools

The MCP server provides four tools:

| Tool          | Description                             |
| ------------- | --------------------------------------- |
| `search`      | Find APIs by describing what you need   |
| `get_details` | Get full parameter info for an endpoint |
| `integrate`   | Get ready-to-use code snippets          |
| `use`         | Execute an API call                     |

## Example Conversation

<Accordion title="See it in action - Multi-API workflow">
  **You:** I need to find contact info for the CEO of Stripe - get their email and phone number

  **Claude:** *uses search tool*

  I found several lead enrichment APIs. Let me chain them together:

  **Claude:** *uses the `use` tool with Sixtyfour /enrich-lead*

  Found the CEO: Patrick Collison. Now let me get contact details...

  **Claude:** *uses the `use` tool with Sixtyfour /find-email*

  Found email: [patrick@stripe.com](mailto:patrick@stripe.com)

  **Claude:** *uses the `use` tool with Sixtyfour /find-phone*

  Found phone number

  **3 API calls, one conversation**

  Here's what I found:

  * Name: Patrick Collison
  * Title: CEO at Stripe
  * Email: [patrick@stripe.com](mailto:patrick@stripe.com)
  * Phone: +1-xxx-xxx-xxxx
  * LinkedIn: linkedin.com/in/patrickcollison
