Tools 4

create_event
annotations: none low

Create a calendar event. start/end in ISO 8601 format (YYYY-MM-DDTHH:MM:SS). Behavior: This tool generates structured output without modifying external systems. Output is deterministic for identical inputs. No side effects. Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage. When to use: Use this tool when you need structured analysis or classification of inputs against established frameworks or standards. When NOT to use: Not suitable for real-time production decision-making without human review of results. Args: title (str): The title to analyze or process. start (str): The start to analyze or process. end (str): The end to analyze or process. timezone (str): The timezone to analyze or process. description (str): The description to analyze or process. attendees (str): The attendees to analyze or process. api_key (str): The api key to analyze or process. Behavioral Transparency: - Side Effects: This tool is read-only and produces no side effects. It does not modify any external state, databases, or files. All output is computed in-memory and returned directly to the caller. - Authentication: No authentication required for basic usage. Pro/Enterprise tiers require a valid MEOK API key passed via the MEOK_API_KEY environment variable. - Rate Limits: Free tier: 10 calls/day. Pro tier: unlimited. Rate limit headers are included in responses (X-RateLimit-Remaining, X-RateLimit-Reset). - Error Handling: Returns structured error objects with 'error' key on failure. Never raises unhandled exceptions. Invalid inputs return descriptive validation errors. - Idempotency: Fully idempotent — calling with the same inputs always produces the same output. Safe to retry on timeout or transient failure. - Data Privacy: No input data is stored, logged, or transmitted to external services. All processing happens locally within the MCP server process.

find_free_slot
annotations: none low

Find free time slots. busy_slots: JSON array of {start, end} objects. date: YYYY-MM-DD. Behavior: This tool is read-only and stateless — it produces analysis output without modifying any external systems, databases, or files. Safe to call repeatedly with identical inputs (idempotent). Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage. When to use: Use this tool when you need structured analysis or classification of inputs against established frameworks or standards. When NOT to use: Not suitable for real-time production decision-making without human review of results. Args: busy_slots (str): The busy slots to analyze or process. date (str): The date to analyze or process. duration_minutes (int): The duration minutes to analyze or process. work_start (str): The work start to analyze or process. work_end (str): The work end to analyze or process. api_key (str): The api key to analyze or process. Behavioral Transparency: - Side Effects: This tool is read-only and produces no side effects. It does not modify any external state, databases, or files. All output is computed in-memory and returned directly to the caller. - Authentication: No authentication required for basic usage. Pro/Enterprise tiers require a valid MEOK API key passed via the MEOK_API_KEY environment variable. - Rate Limits: Free tier: 10 calls/day. Pro tier: unlimited.

Safe to retry on timeout or transient failure. - Data Privacy: No input data is stored, logged, or transmitted to external services. All processing happens locally within the MCP server process.

calculate_duration
annotations: none low

Calculate duration between two ISO 8601 datetime strings. Behavior: This tool is read-only and stateless — it produces analysis output without modifying any external systems, databases, or files.

timezone_convert
annotations: none low

Convert time between UTC offsets. Offsets in hours (e.g., -5 for EST, +1 for CET). Behavior: This tool is read-only and stateless — it produces analysis output without modifying any external systems, databases, or files. Safe to call repeatedly with identical inputs (idempotent). Free tier: 10/day rate limit. Pro tier: unlimited. No authentication required for basic usage. When to use: Use this tool when you need structured analysis or classification of inputs against established frameworks or standards. When NOT to use: Not suitable for real-time production decision-making without human review of results. Args: datetime_str (str): The datetime str to analyze or process. from_offset (float): The from offset to analyze or process. to_offset (float): The to offset to analyze or process. api_key (str): The api key to analyze or process. Behavioral Transparency: - Side Effects: This tool is read-only and produces no side effects. It does not modify any external state, databases, or files. All output is computed in-memory and returned directly to the caller. - Authentication: No authentication required for basic usage.
