The Honeycomb MCP server has a solid foundation with 14 well-named tools following verb_noun conventions (list_*, get_*, run_query, analyze_columns). All tools have descriptions and basic input schemas with typed parameters. However, there are significant gaps: parameter descriptions are minimal or absent in several tools, output schemas are not documented, error handling lacks recovery guidance, and the server does not implement modern MCP patterns like tool annotations or structured error categories. The codebase shows thoughtful error handling infrastructure (handleToolError, HoneycombError class) but this is not reflected in tool-level descriptions or recovery hints. Descriptions are generally adequate (50-200 chars baseline) but many parameters lack context about expected formats, ranges, or constraints. No tool documents what it returns, making it difficult for LLMs to plan downstream calls.

• Document output schemas for all tools. Create a schema definition showing what fields run_query returns (e.g., {results: [{timestamp, value, dimensions}], metadata: {total_rows, query_time_ms}}) so LLMs can extract values correctly.
• Expand the run_query 'query' parameter description with an example structure and allowed operators. State: 'The query object must include: filters (array of {field, operator, value}), aggregations (array of {function, field}), time_range (from, to in ISO 8601). Valid operators: eq, ne, gt, gte, lt, lte, in, not_in.'
• Enhance all parameter descriptions to include constraints and formats. Example: 'environment (string, 1-255 chars, alphanumeric + hyphens): The Honeycomb environment name. If you only have a user token, query list_environments() first to find the correct environment.'
• Add pagination support to all list_* tools. Advertise limit (default 20, max 100), offset, and response field total_count. Update descriptions: 'Returns up to 20 datasets per call. Use offset for pagination.'
• Implement tool annotations in the tool definition. Mark all tools with readOnlyHint=true and idempotentHint=true. This enables proper MCP capability negotiation.
• Add error recovery hints to descriptions. Example for list_datasets: 'If the environment is not recognized, verify HONEYCOMB_API_KEY is set and call with a valid environment name from your Honeycomb account.'
• Document what columns are returned by list_columns and analyze_columns. State whether they return human-friendly names or internal IDs, and how to use them in downstream run_query calls.
