# `Mead.MCP.Transport.Http`
[🔗](https://github.com/albertosca/mead/blob/main/lib/mead/mcp/transport/http.ex#L1)

The Streamable HTTP transport of MCP: every message is a POST, and the answer is either one
JSON body or an event stream that ends with the answer.

## Options

  * `:url` - `http://` or `https://` endpoint (required).
  * `:headers` - a list of `{name, value}` binaries sent on every request, for credentials.
  * `:receive_timeout` - milliseconds to wait for an answer; defaults to 30 000.
  * `:req_options` - extra options merged into every `Req` request, used by tests to stub the
    network.

Each POST runs in its own task, so a slow answer never blocks another request. The whole
response is read before it is decoded, which is why no incremental delivery is needed from
`Req`. The server may assign a session id in the `mcp-session-id` header; it is echoed on every
later request, and a 404 after a session was assigned means the session expired, which closes
the transport so the connection starts over.

Not verified against a real remote server: only against a `Plug` double. Reasons never contain
the configured headers.
