# Feat: Enhance Knowledge Base MCP Server Startup with Health Checks

This ticket documents the enhancement of the `main()` function in `ai/mcp/server/knowledge-base/mcp-stdio.mjs` to include robust startup logic, health checks, and status reporting, aligning it with the capabilities of the Memory Core MCP server.

**Motivation:**
The previous startup sequence for the Knowledge Base MCP server was basic, lacking detailed health checks and status reporting. By integrating a comprehensive startup sequence, we achieve:
*   **Improved Diagnostics:** Clearer reporting of server health, ChromaDB connectivity, and collection status at startup.
*   **Enhanced User Guidance:** Actionable tips for resolving issues (e.g., starting ChromaDB) are provided when the server is unhealthy.
*   **Consistency:** Standardized startup behavior across different MCP servers, making it easier to manage and debug.

**Changes Implemented:**

1.  **Imports:** Added `ChromaManager` and `HealthService` imports to `mcp-stdio.mjs`.
2.  **`main()` Function Refactoring:**
    *   Integrated `await ChromaManager.ready()` to ensure async services are initialized.
    *   Incorporated `const health = await HealthService.healthcheck()` to perform an initial health check.
    *   Implemented an `if/else if/else` block to report server status (`unhealthy`, `degraded`, `healthy`) with detailed messages and guidance.
    *   Adapted all messages and collection checks to the "Knowledge Base" context and its single collection.
    *   The "fully healthy" block has been left empty for now, as per the user's instruction, with a note that specific actions for a healthy state will be addressed in a follow-up ticket.
    *   Updated final `logger.info` messages to reflect "neo-knowledge-base MCP".

This enhancement significantly improves the startup experience and diagnostic capabilities of the Knowledge Base MCP server.
