# Streamable HTTP

The MCP transport over a single HTTP endpoint that accepts JSON-RPC POSTs and may answer with JSON or a server-sent event stream. Example: curl -X POST https://example.com/mcp -H 'Accept: application/json, text/event-stream'. Related row: AR-ACT-03 (MCP over Streamable HTTP). The guide "Add OAuth metadata" covers a row that names Streamable HTTP.

## Where it appears on the checklist

-   [AR-ACT-03](https://agentreadychecklist.com/checklist/ar-act-03/)MCP over Streamable HTTP: Expose an MCP server over Streamable HTTP at /mcp; keep the docs MCP public and gate the product MCP with OAuth and PKCE; list it in the MCP Registry with a server.json.

## Asked about it

### Where should the MCP server live?

The spec says Streamable HTTP at /mcp, docs MCP public, product MCP behind OAuth with protected-resource metadata and PKCE. The Vercel guide calls /mcp a stable choice but not a protocol requirement.
