### Description (declared)

# yade-mcp-bridge

[![PyPI](https://img.shields.io/pypi/v/yade-mcp-bridge)](https://pypi.org/project/yade-mcp-bridge/)

HTTP + SSE bridge that runs inside a YADE process and enables execution tools for [yade-mcp](https://pypi.org/project/yade-mcp/).

## Features

- **Async tasks with progress polling.** Submit a long simulation script
  (`execute_task`) and poll its status and paginated log while it runs
  (`check_task_status`).
- **Live code during a run.** Send `execute_code` at any time to inspect
  state or tune parameters mid-cycle — no need to bake probes into the
  script up front. It shares the simulation's `__main__` namespace.
- **Graceful interrupt.** Stop a long cycling task on request
  (`interrupt_task`) without killing the YADE process.
- **Unified output capture.** Python `print` and YADE console output are
  interleaved in execution order in the task log.
- **Zero third-party dependencies.** Pure stdlib HTTP + SSE.

## Architecture

YADE's Qt GUI objects are main-thread-only, so the bridge keeps
`execute_code` on the main thread while running each task on its own
thread — a long `O.run()` then never blocks the server or live code.

```

- **HTTP + SSE server (background thread).** A threaded HTTP server takes
  `POST /<command>` request/response calls and serves one long-lived
  `GET /events` SSE stream. It hands work off rather than touching YADE
  directly, so lightweight calls (status, interrupt) stay responsive even
  while a long task runs.
- **execute_code pump.** `execute_code` submissions are serialized through
  a queue …
