# Stack Exchange — how to use (mcp.ai)

Stack Exchange is a network of Q&A communities where users ask questions, share knowledge, and collaborate on topics like coding, math, and more

## Option A — via MCP (recommended)
Remote MCP endpoint (HTTP, streamable): `https://api.mcp.ai/p_stack_exchange?ms=1781541780000`
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. `stack_exchange_get_collective_questions`).

## Option B — via direct REST API
Base URL: `https://api.mcp.ai/api/stack_exchange`
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/stack_exchange/_endpoints`
