note: >-
  Fragment markets MCP-style AI-agent access to the ledger, but no official
  hosted/remote MCP server endpoint or MCP package was published on the docs,
  npm (@modelcontextprotocol), or the fragment-dev GitHub org at capture time.
  The tool list below is a CANDIDATE mapping of Fragment GraphQL operations to
  MCP tools — a governance starting point, not a provider claim.
