Single-tool server with clear naming ('count') and a well-structured input schema. Tool description is adequate (89 chars, within baseline 34 - 392 range). Input parameters have types and descriptions. However, output schema is not formally documented, the tool returns a JSON object but the response structure is not declared in the tool definition, forcing LLMs to infer field names. Error handling is basic (generic error messages without recovery guidance). No parameter validation constraints (e.g., wpm must be positive is checked at runtime but not declared in schema). Missing tool annotations (readOnlyHint, idempotentHint) that would clarify intent.

• Add explicit output schema to tool definition: document that 'count' returns an object with fields: characters (integer), characters_no_spaces (integer), words (integer), sentences (integer), paragraphs (integer), reading_time_minutes (number), reading_time_display (string).
• Add JSON Schema constraints to 'wpm' parameter: set minimum: 1, maximum: 1000 (reasonable bounds for reading speed). Update description to: 'Words per minute for reading-time estimate (1 - 1000, default 200).'
• Enhance error messages with recovery guidance. E.g., 'Invalid wpm: got <value>, must be a positive integer (1 - 1000).' For unknown tools, return 'Unknown tool: <name>. Available tools: count.'
• Add tool annotations: set readOnlyHint: true and idempotentHint: true in the tool definition to signal that 'count' is safe to retry and does not modify state.
• Consider migrating to HTTP+SSE or Streamable HTTP transport to enable remote deployment and integration with hosted MCP clients.
