What is MCP?

The Model Context Protocol (MCP) is an open standard that lets AI-powered IDEs and tools connect to external data sources. Sixtyfour provides two MCP servers:
ServerURLPurpose
Documentationhttps://docs.sixtyfour.ai/mcpSearch Sixtyfour docs from your IDE
Sixtyfour Intelligencehttps://mcp.sixtyfour.ai/mcp?api_key=YOUR_API_KEYRun company and people intelligence through one async MCP endpoint

​
Setup

Add both servers to your IDE’s MCP configuration file: 
{
  "mcpServers": {
    "sixtyfour-docs": {
      "url": "https://docs.sixtyfour.ai/mcp"
    },
    "sixtyfour-intelligence": {
      "url": "https://mcp.sixtyfour.ai/mcp?api_key=YOUR_API_KEY"
    }
  }
}
Replace YOUR_API_KEY with your Sixtyfour API key. The exact location of the MCP configuration file varies by IDE.

​
Common IDE config paths

IDEConfig location
Cursor.cursor/mcp.json in your project root or ~/.cursor/mcp.json globally
VS Code (Copilot).vscode/mcp.json in your project root
Claude CodeSee CLI commands in each server section below
Windsurf~/.codeium/windsurf/mcp_config.json

​
Documentation MCP

Gives your IDE’s AI assistant direct access to Sixtyfour docs, API references, code examples, and guides — without leaving your editor.
This command is scoped to the directory you run it from. To make the server available across all projects, add --scope user to each command.

​
Claude Code

claude mcp add --transport http sixtyfour-docs "https://docs.sixtyfour.ai/mcp"

​
Example usage

  • “How do I use the company-intelligence endpoint?”
  • “What parameters does find-email accept?”
  • “Show me an example of using webhooks with Sixtyfour”

​
Sixtyfour Intelligence MCP

Runs company and people intelligence from Claude Code or another MCP client. The server exposes one async intelligence endpoint, so the client does not need to call /company-intelligence-async, /people-intelligence-async, or /job-status/{task_id} directly.
This MCP server supports both company and people intelligence. Use the same server for both, and describe the target plus requested fields in plain English.

This command is scoped to the directory you run it from. To make the server available across all projects, add --scope user to each command.
claude mcp add --transport http sixtyfour-intelligence "https://mcp.sixtyfour.ai/mcp?api_key=YOUR_API_KEY"

​
Example usage

  • “Use Sixtyfour company intelligence to find US companies with 100 to 5000 employees.”
  • “Use Sixtyfour company intelligence to research Anthropic and return headquarters, employee count, funding stage, and key executives.”
  • “Use Sixtyfour people intelligence to enrich this person: Saarth Shah, CEO & Co-Founder at Sixtyfour AI.”
  • “Use Sixtyfour company intelligence to find the CTO and VP of Engineering at Sixtyfour AI.”
Ask Claude Code to return the generated request payload if you want to reuse it against the HTTP API.
