The Log Reader Server provides a single tool with a clearly defined purpose and reasonable input schema. The tool name 'log-reader' is descriptive and the description explains what it does. However, there are significant gaps in parameter-level guidance, output schema documentation, and error handling patterns. The tool accepts filters as an object but the schema lacks proper enumeration constraints and some descriptions are too generic. Output is returned as markdown-wrapped JSON without a documented structure for the LLM to parse. Error handling is minimal, the catch block returns a generic message instead of actionable recovery guidance.

• Replace free-form 'level' and 'channel' string parameters with enum types declaring valid values (e.g., ['error', 'warning', 'info', 'debug', 'notice'] for level). This prevents hallucinated invalid values.
• Document the output schema explicitly. Define a structure like: {logs: [{id, level, message, channel, timestamp, context, extra}, ...], total_count: int, has_more: bool}. Specify types and what each field contains.
• Add pagination support: include 'limit' (default 50, max 500) and 'offset' parameters. Return total_count and has_more in the response so LLMs can iterate through large result sets.
• Improve error messages to be actionable. Instead of 'Failed to read logs. Check server logs for details.', return specific guidance: 'Validation failed: date_from must be before date_to' or 'No logs found for the given query. Try broadening the date range or removing filters.'
• Clarify the 'query' parameter: 'Full-text search across log messages, context, and extra fields. Supports substring matching (case-insensitive). Example: search for 'user' to find logs mentioning any user-related event.'
• Add a 'format' parameter to control output shape (e.g., 'json', 'summary'). Returning raw JSON inside markdown is inefficient for parsing. Return structured output directly using MCP's Content::Object or keep markdown but document the internal structure clearly.
• Consider adding a tool annotation (readOnlyHint: true) since log-reader only reads and never modifies state. This helps agents reason about safety and whether the tool can be called speculatively.
