# 0CodeKit — how to use (mcp.ai)

Connect your 0CodeKit account and use 8 tools for developer tools straight from your AI agent. Connect with your own API key. 0CodeKit provides utility APIs for AI, document and image processing, data conversion, validation, generation, storage, and automation workflows.

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_0codekit?ms=1787295780000`
Add it as a custom/remote MCP connector in your client (Claude, Cursor, VS Code…), then authenticate when prompted. Once connected, ask the agent to use the server's tools (e.g. `0codekit_calculate_bmi`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/0codekit`
Auth: `Authorization: Bearer sk_live_…` — create a workspace API key at https://mcp.ai/settings/api-keys
Discover endpoints: `GET https://api.mcp.ai/api/0codekit/_endpoints`
