Connect Your AI Tools

Choose your integration method based on your tool's capabilities

RECOMMENDED

MCP Integration

Native protocol for MCP-compatible AI tools

The Model Context Protocol (MCP) provides native integration with 29 tools, 9 resources, and 6 prompts. Your AI tool calls ACE functions directly.

Best for:

• Claude Desktop, Claude Code
• Cursor, Windsurf, VS Code
• ChatGPT Codex CLI, Gemini CLI
• Any MCP-compatible tool

ALTERNATIVE

REST API Integration

Direct HTTP calls for any tool or custom applications

Use curl/HTTP requests to access all 210+ API endpoints. Works with any tool that can execute bash commands or make HTTP requests.

Best for:

• Tools without MCP support
• Custom integrations & scripts
• Web applications & backends
• Any HTTP-capable client
