A modular MCP (Model Context Protocol) server implementation with authentication, tools, resources, and prompts support
Server has 4 tools with reasonable coverage. All tools have descriptions (10-60 chars range) and input schemas with typed parameters. However, descriptions are generic and fall short of LLM-optimization standards (most are <50 chars). Parameter descriptions are present but minimal. Output schemas are not explicitly documented. Error handling exists but lacks recovery guidance. Tool naming is clear and action-oriented (add, log_, get_). The MongoDB-backed logging tools have appropriate WRITE/READ_ONLY risk markers, though risk is not formally declared in schema. One tool (add) is trivial; three are domain-focused on agent logging. Overall decent baseline but several patterns from the 54 Agentic Tool Patterns are not fully implemented.
Add two numbers together.
Retrieve AI agent logs from MongoDB with optional filtering.
Get statistics for a specific AI agent from MongoDB.
Log an AI agent interaction to MongoDB.
Descriptions are under 100 characters for all tools; LLM-optimized descriptions should be 50-200 chars explaining WHAT, WHEN, and WHY. Current descriptions are too terse.
Output schemas are not explicitly documented in parameter definitions. Tools return complex objects (List[Dict], Dict[str, Any]) but the structure of returned fields is not declared, forcing LLMs to infer shape.
Error handling returns generic responses (empty list, empty dict, False) without recovery guidance. Exceptions are logged but not returned to LLM with actionable next steps.

get_agents_logs returns unbounded list results (limited only by optional 'limit' param defaulting to 100). No pagination metadata (total_count, next_cursor) documented, violating paginated-result pattern.
Date parameter format validation happens at runtime with silent failures (returns [] or {}). Should validate early and return clear error: 'Invalid start_date: got "2024-1-1", use ISO format YYYY-MM-DD'.
No explicit permission scoping declared (e.g., 'read:logs', 'write:logs'). Tools that write to MongoDB should declare required permissions for least-privilege configuration.
Tool 'add' is trivial (simple integer addition) and does not belong in a production logging/monitoring server. It appears to be a placeholder and dilutes the tool set.
