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:| Server | URL | Purpose |
|---|---|---|
| Documentation | https://docs.sixtyfour.ai/mcp | Search Sixtyfour docs from your IDE |
| Company Filter Search | https://mcp.sixtyfour.ai/mcp?api_key=YOUR_API_KEY | Run company filter searches via MCP tools |
Setup
Add both servers to your IDE’s MCP configuration file:Replace
YOUR_API_KEY with your Sixtyfour API key. The exact location of the MCP configuration file varies by IDE.Common IDE config paths
| IDE | Config 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 Code | See 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
Example usage
- “How do I use the enrich-company endpoint?”
- “What parameters does find-email accept?”
- “Show me an example of using webhooks with Sixtyfour”
Company Filter Search MCP
Lets Claude Code or another MCP client drive the full company filter search flow, discover fields, inspect top values, and run paginated searches — without calling the HTTP endpoints directly.Claude Code
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.Example usage
- “Use Sixtyfour company filter search to find US companies with 100 to 5000 employees.”
- “Use Sixtyfour company filter search to show the top values for
industryfor private Canadian companies.” - “Use Sixtyfour company filter search to build a
simple_filtersquery for AI infrastructure companies and return the first page of results.”
Ask Claude Code to return the generated
simple_filters or filters payload if you want the underlying query as JSON.
