This MCP server has 7 tools split across two contexts (fast-echo and mcp-simple). While basic schemas and descriptions exist, they are generic and lack depth required for production LLM use. Tool names are action-oriented (echo_*, start-notification-stream) which is positive, but descriptions are minimal (1-2 sentences). Parameters lack constraints (enums, ranges, formats). No error handling guidance is visible. The echo tools are trivial demonstration utilities. The notification streaming tool has slightly better structure but still lacks comprehensive documentation. Schemas are present but sparse, no output documentation, no pagination details, no field-level guidance for chaining subsequent calls. Overall, this reads as an early-stage demo rather than production-ready tooling.

• Expand tool descriptions to 50 - 150 characters. For echo_tool, replace 'Echo the input text back to the user' with 'Returns the input text unchanged. Use this to verify the connection is working and text processing is not interfering. Idempotent; safe to retry.'
• Add constraints to numeric parameters: echo_repeat 'times' should declare min=1, max=1000; start-notification-stream 'count' and 'interval' should declare valid ranges (e.g. count 1 - 1000, interval 0.1 - 3600).
• Document output schemas. Echo tools return {result: string}; start-notification-stream returns {notifications: [{timestamp, count, caller}]}. Make this explicit so LLMs know what fields to expect.
• Add error handling guidance. E.g. 'Returns error if text exceeds 100000 characters (retryable; reduce input size)' or 'Stream may timeout after 5 minutes (non-retryable; use smaller count).'
• Rename 'start-notification-stream' to 'start_notification_stream' (snake_case) for consistency.
• For echo_repeat, clarify whether 'times=2' means the result contains 2 copies or 3 total (original + 2 repeats). Current description is ambiguous.
• Add parameter descriptions that match LLM-friendly language: 'text (string, max 100000 chars): The message to echo. Longer strings are rejected.' rather than bare param names.
• Consider adding an 'idempotentHint: true' annotation to all read-only echo tools to signal to agents that repeated calls are safe.
