note: 'No official hosted/remote MCP server was found for Halliday (they publish a Claude Code plugin
  + skill, not an MCP server). This is a CANDIDATE tool list derived one-per-operation from the Halliday
  API V2 OpenAPI, to seed a future MCP surface. Read operations are agent-safe; write operations (confirm/withdraw)
  carry onchain consequence — gate per the agentic-access profile.
