notes: Outpost does not publish a hosted/remote MCP server. Outpost does publish a "Copy integration plan
  for LLM" brief for AI coding assistants, but that is a scaffolding prompt, not an MCP server. The tool
  list below is a candidate derived from the documented REST operations (Outpost publishes no OpenAPI,
  so operations are named from the docs, and only endpoints with a confirmed path carry one). Nothing
  here is a published Outpost tool.
