casino-mcp 0.1.0

First packaged release. The control plane works and is tested; the tools that return physics
to the model are not shipped yet.

pip install casino-mcp

On PyPI: https://pypi.org/project/casino-mcp/0.1.0/

Added

• MCP server over stdio with four tools: casino_run, casino_status, casino_stop,
  casino_list_jobs. No generic shell tool, by design.
• An on-disk job registry under $XDG_STATE_HOME/casino-mcp, so a calculation outlives the
  server that started it, and a launcher process per job, so the whole tree
  (runqmc → mpirun → casino) can be signalled as one group and its exit code recorded.
• parse_out: a CASINO out file as structured phases, every number carrying the line it
  was read from. No MCP, no dependencies. Checked against envmc over 526 example files.
• Configuration through the environment, which is what .mcp.json can set per server
  registration: CASINO_HOME, CASINO_ARCH, CASINO_RUNQMC, CASINO_MCP_STATE_DIR,
  CASINO_MCP_FORBID. Every other default is a constant in settings.py.
• A casino-mcp command: serve, config, run, status, stop, jobs, parse.
• Guardrails against destroying results: a directory that already holds an out, one whose
  out is tracked by git, one another runqmc has locked, and a $CASINO_MCP_FORBID list
  that has no per-call override.
• Provenance: every job record freezes the command and the path, size and mtime of the
  casino binary it ran.
• Tests: 102 unit tests that need no CASINO (a fake runqmc stands in for the real one), plus
  an opt-in integration suite that drives real calculations over real stdio MCP.

Notes

• parse_out derives exactly one number: the sample-variance error of a single-block run,
  which CASINO does not print. It is taken from the one block as envmc does, and labelled.
• Nothing shells out to envmc/endmc at runtime; endmc misparses numbers under a non-C
  locale.

Requires Python 3.11+ and a working CASINO installation. The package does not bundle, build
or replace CASINO — it drives runqmc.
