  notes: >-
    The bearer token is a project API key with prefix lma_, created in Lemma
    project settings (platform.uselemma.ai) and shown only once at creation.
    SDK clients read it from LEMMA_API_KEY (with LEMMA_PROJECT_ID, prefix
    proj_, selecting the project). The same key authenticates the Platform
    API, trace ingest, and the remote MCP server at
    https://api.uselemma.ai/mcp (Authorization: Bearer header). Missing
    credentials return 401; the entire api.uselemma.ai host is authenticated.
