note: Lang.ai publishes no official hosted or remote MCP server — no server is listed in the docs, the
  lang-ai GitHub organization, or the public MCP registries, and the company is now part of Capacity.
  The tools below are a candidate surface derived one-to-one from the documented REST operations, offered
  as a starting point for anyone wrapping the Lang.ai API for agents. Do not present this as a Lang.ai-published
  server.
server:
  name: langai
  transport: stdio
  url: null
  auth:
    type: bearer
    env: LANGAI_API_TOKEN
    note: Also requires the tenant subdomain, e.g. LANGAI_INSTANCE=company for https://company.lang.ai/api/v1.
