pycycle-mcp
pycycle-mcp is a lightweight Model Context Protocol server for pyCycle/OpenMDAO
engine-cycle workflows. The repository includes deterministic examples/tests so
local development and CI can validate tooling contracts without requiring a full
runtime installation of pyCycle/OpenMDAO assets.
Overview
The project currently provides:
- A FastMCP-powered server with stdio and HTTP-compatible transports.
- Tooling for cycle lifecycle, variable inspection/updates, execution, sweeps, and total-derivative evaluation.
- Pydantic-backed validation with structured MCP-style error payloads.
- Deterministic examples for repository scaffolding checks and smoke tests.
Quickstart
Requires Python 3.12+.
python3 -m venv .venv
source .venv/bin/activate
make dev
make test
make ci
Start the server over stdio:
pycycle-mcp --transport stdio
Inspect the non-blocking HTTP transport configuration example:
PYTHONPATH=src python3 examples/server/http_launch_config.py
Examples
The examples are deterministic and aligned with the current repository contracts.
