GSA Per Diem MCP Server

What the code does

We read the source, 22 h ago · rules 995398eba69f

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

  execFileSync(PYTHON, [join(ROOT, "deploy/gsa-perdiem/parity/build_corpus.py")], {cwd: PACKAGE, env: pythonEnv, stdio: ["ignore", "ignore", "inherit"]});
