The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
get_todayGet today's overview: Jalali/Gregorian/Hijri date, occasions & holidays of Iran, My-Day tasks, tasks due today, overdue tasks and today's events. Call this first to know the current Persian date.
get_agendaAgenda for a date range: per-day tasks due, events, Iranian occasions/holidays, plus overdue tasks. Great for "برنامه این هفته چیه؟".
list_tasksList tasks. view: myday | important | today | overdue. Or filter by list_name / search query.
create_taskCreate a task. If list_name does not exist it is created. Use my_day=true to add to «روز من».
update_taskUpdate fields of a task by id. Only provided fields change. Set a field to empty string/null to clear it.
complete_taskMark a task as done. If it repeats, the next occurrence is created automatically and returned.
delete_taskDelete a task permanently.
list_listsGet all task lists (with open task counts) and groups.
create_listCreate a new task list.
list_eventsList calendar events in a date range (recurring events are expanded).
create_eventCreate a calendar event (قرار، جلسه، تولد…). Use repeat {freq:"yearly"} for birthdays.
update_eventUpdate fields of an event by id.
delete_eventDelete a calendar event permanently.
searchSearch across tasks (title/note/steps) and events.
convert_dateConvert a date between Jalali / Gregorian / Hijri and get its weekday.
plan_my_dayGet everything needed to plan the user's day: My-Day tasks, due/overdue/important tasks, today's events with times, and occasions. After reasoning, use update_task (my_day=true, reminder_at=…) to schedule tasks into the day.
send_notificationSend a notification to the user's Windows and phone (ntfy) right now. Use for important alerts the user asked to be pinged about.
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.
@modelcontextprotocol/sdk has cross-client data leak via shared server/transport instance reuse
Anthropic's MCP TypeScript SDK has a ReDoS vulnerability
Model Context Protocol (MCP) TypeScript SDK does not enable DNS rebinding protection by default
CALSO_PORTTool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
17/17 tools missing one or more hints — get_today (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_agenda (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_tasks (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +14 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
14/17 tool handlers declare input schemas (82%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
Only 0/17 tool handlers wrap calls in try/catch (0%)
Wrap each tool handler body in try/catch and return a structured error response.
License file
No license file
Add a LICENSE file (MIT, Apache-2.0, etc.).
Tests exist
No test files found
Add tests that exercise each declared tool.
Shell command execution
1 child_process call — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
Production dependencies are patched
0 critical, 3 high severity in production deps — @modelcontextprotocol/sdk@1.12.0 (high), @modelcontextprotocol/sdk@1.12.0 (high)
Run npm audit fix, or upgrade the affected packages to a non-vulnerable version.
