Strong foundation with clear verb-based naming and comprehensive parameter schemas. All 7 tools have descriptions and typed input schemas. However, output schemas are undocumented (no return type specifications visible), and descriptions lack LLM-optimized guidance on when to use each tool vs. alternatives. Parameter descriptions are adequate but could be more prescriptive about formats and constraints. Error handling and recovery guidance are absent from tool definitions.

• Document return types for all tools. Specify that list_datasources returns array of {uid, name, type, url, isDefault, readOnly}, query_prometheus returns {status, data: {resultType, result}}, etc. This enables LLM planning.
• Add error recovery guidance to tool descriptions. E.g., 'If query times out, try reducing the time range or increasing timeout parameter. If datasource not found, call list_datasources to verify UID.'
• Enhance parameter descriptions with explicit format constraints. Change 'Unix timestamp or RFC3339 string' to 'Unix timestamp (seconds since epoch, e.g. 1704067200) or RFC3339 string (e.g. 2024-01-01T00:00:00Z)'.
• Implement pagination with offset/limit and total_count for list_* tools. Add 'offset' parameter and return {items: [...], total: N, offset: M} to support large result sets.
• Clarify tool selection in descriptions. Add 'Use this for instant queries at a single point in time' to query_prometheus and 'Use this for time-series data over a range' to query_prometheus_range.
