| 1 | """MuseHub MCP tool executor — server-side logic for all musehub_* MCP tools. |
| 2 | |
| 3 | This module is the execution backend for MuseHub browsing tools exposed via |
| 4 | MCP. Each public function opens its own DB session via ``AsyncSessionLocal``, |
| 5 | delegates to ``musehub_repository`` for persistence access, and returns a |
| 6 | typed ``MusehubToolResult``. |
| 7 | |
| 8 | Design contract |
| 9 | --------------- |
| 10 | - All functions are async and return ``MusehubToolResult`` on both success |
| 11 | and failure (no exceptions propagate to the MCP server). |
| 12 | - ``MusehubToolResult.ok`` distinguishes success from failure. |
| 13 | - ``MusehubToolResult.error_code`` is one of the ``MusehubErrorCode`` literals |
| 14 | (resource-specific not-found codes, input validation, state, auth, infra). |
| 15 | - Callers (``MuseMCPServer._execute_musehub_tool``) pattern-match on |
| 16 | these codes to build appropriate ``MCPContentBlock`` responses. |
| 17 | - This module must NOT import MCP protocol types — it is pure service layer. |
| 18 | |
| 19 | ``AsyncSessionLocal`` is imported at module level so tests can patch it as |
| 20 | ``musehub.services.musehub_mcp_executor.AsyncSessionLocal``. |
