The Google Calendar Semantic Search Tool
Search your vectorized Google Calendar by meaning across calendars and date ranges, filtered by attendees and event type — the retrieval layer for any agent that reasons over your schedule.
The meeting happened — but which one was it?
Calendar search matches event titles, not what a meeting was about. When you need "the sync where we decided the launch date," a keyword search over terse, inconsistent titles rarely finds it.
Titles are terse
Half your events are called "Sync" or "1:1" — the title tells you nothing about the topic.
Context spans calendars
The relevant event might be on a shared or project calendar you forgot to check.
No relevance ranking
Native search returns matches by date, not by how well they fit your intent.
Schedules are sensitive
Who met whom and when is data that can’t be sent to a hosted assistant.
Meaning-aware search over your calendar
Semantics
Describe it, don’t title it
Find the meeting by what it was about.
The tool embeds your query and matches it against vectorized calendar events, surfacing the right meeting even when its title is generic or shares no keywords with your question.
- Embedding-based matching
- Across multiple calendars
- Similarity score per hit
- Tunable top_k up to 50
Beyond titles
Precision
Narrow by calendar, date, and type
Only the events worth surfacing.
Combine the semantic query with filters for calendar, date range, presence of attendees, and all-day vs. timed events so an agent retrieves exactly the events that matter.
Calendar, date, attendees
Governance
Private and on-premise
Your schedule stays private.
Indexing and search run inside your perimeter, scoped per user with audit logging, so sensitive meeting data is safe to make searchable by an agent.
Per-tenant, logged
Parameters
The google_calendar_vector_search tool accepts these inputs when an agent calls it. Required inputs are flagged.
default: 10 Optional Maximum number of results to return (1–50).
Where calendar search pays back

Questions about the Google Calendar Semantic Search tool
What is the Google Calendar semantic search tool?
It searches your vectorized Google Calendar events by meaning and returns ranked matches with similarity scores. Assigned to an agent, it finds the right meeting even when event titles are terse or generic.
Can I limit it to one calendar?
Yes. Provide calendar_id to scope the search to a specific calendar, or omit it to search everything indexed for the user.
What filters are supported?
You can narrow by calendar_id, date range (date_from/date_to), whether the event has attendees, and whether it is an all-day event — combined with the semantic query.
Is our schedule exposed?
No. Indexing and search run on-premise or in your sovereign cloud, scoped per user and audit-logged, so calendar data never leaves your perimeter.
How does it pair with other tools?
It is often assigned alongside Gmail and Google Drive semantic search so an agent can reason across meetings, mail, and files together.
