Two Transports (SSE's a Ghost)

Glitchy synthwave, 118 BPM, arpeggiated bass, vocoder chant hook, half-time rap break

V5.5

[Intro]
(cold synth hum, distant arpeggio)
(vocoder whisper) two real transports... one's a ghost...

[Verse 1]
Same exam question, looks so clean,
three little options on the screen.
stdio, Streamable HTTP, and one called "SSE" —
you reach for the name that you half-remember,
and you lose the mark, oh-oh, by December.

[Pre-Chorus]
(build)
Don't pick from taste, don't pick from vibe —
let the deployment decide.

[Chorus]
(drop)
Two transports — choose by where it runs!
stdio local, HTTP when it's shared by everyone. (let's go!)
Two transports — and "SSE" is a ghost,
it got deprecated, so don't pick the one you miss the most.

[Verse 2]
One dev, one machine, in the very same room?
The client spawns a child process, stdin/stdout zoom.
But a team that all connects, or it's live in production —
that's a service on the network, Streamable HTTP, no obstruction.

[Verse - Rap]
(half-time)
stdio: the client spawns it as a local child,
pipes JSON over standard in and out, single-user, no port, no URL filed —
lifecycle tied to the session, lowest friction, runs and dies in a while.
Streamable HTTP: remote service, many clients on one endpoint, network mile.
Now the decoy: HTTP+SSE, two endpoints — events stream down, a POST going up —
deprecated, folded into Streamable HTTP's single endpoint, drink from the current cup.
And remote means risk: validate that `Origin` header, bind to one-two-seven-oh-oh-one,
DNS-rebinding can't reach you, secrets through `${VAR}`, never in the file you've spun —
project-scoped `.mcp.json`? The user has to approve it before it's begun.

[Chorus]
(drop)
Two transports — choose by where it runs!
stdio local, HTTP when it's shared by everyone. (oh-oh-oh)
Two transports — and "SSE" is a ghost,
it got deprecated, so don't pick the one you miss the most.

[Bridge]
(half-time, sparse)
Don't grab "SSE" 'cause the word rings a bell —
once-true answers on the menu is exactly how they sell.
And those stdio children pile up across a long, long run —
that's one more reason production leans HTTP when the work is done.

[Final Chorus]
(full drop, vocoder stacks)
Two transports — choose by where it runs! (where it runs!)
stdio local, HTTP when it's shared by everyone.
Two transports — and "SSE" is a ghost,
recognise the name, then reject it — that's the post!

[Outro — call to action]
(spoken over the final fade)
