Summary

AI summary

Added Streamable HTTP transport with Starlette/uVICorn and made OUTPUT_CHANNEL a context‑aware variable.

Full changelog

Added

Added Streamable HTTP transport: PRTS_TRANSPORT=http starts a Starlette
- uvicorn server with /mcp endpoint, /health probe, and HOST/PORT
  env control (defaults 0.0.0.0:3000). stdio remains the default.
  Breaks the 2.0 transport split — the Python implementation now supports
  both stdio and Streamable HTTP.
Added test_e2e_http.py covering HTTP health, initialize + tools/list,
and env-only output_channel behavior.
Declared starlette>=0.27 and uvicorn>=0.31 as explicit dependencies
(previously transitive via mcp[cli]).

Changed

Refactored OUTPUT_CHANNEL from a module-level constant to a
contextvars.ContextVar, paving the way for transport-level overrides.
Tool code is unchanged; render_result resolves the channel via
get_output_channel() at call time. Note: Python HTTP
output_channel is currently process-level (env-only) — FastMCP's session
model makes per-request contextvars invisible to tool code. The
TypeScript HTTP transport supports per-request resolution.
