## MCP tools (1)

### `map_company_event_presence` (~455 tokens)

Map Company Event Presence

Give it a company domain. It returns the third party conferences and trade shows that company publicly says it attends, with a year for each where one can be resolved, as one flat row. The search runs against the company's own domain, which is what stops a brand collision returning another company's events. The company's own conference is reported separately and is never mixed into the attendance list. It finds events for roughly 2 companies in 10, and an empty row is an honest empty row rather than a guess: read coverage, fetch_status and queries_failed to tell a company with no published events apart from a search that could not see. Events dated outside the years you ask for are still returned and flagged, so filter on event year rather than assuming the input filtered for you. This is not an events database and not an exhibitor list: it takes a company and reports what that company publishes. Requires an APIFY_TOKEN and consumes Apify credits. Read only.

Input parameters:

- `company_name` (string): Improves matching when the brand differs from the domain stem, for example Gong for gong.io. Derived from the domain when left empty.
- `domain` (string, required): A single company domain, for example 6sense.com. Protocol and path are stripped.
- `include_own_events` (boolean): Reports whether the company runs its own conference as a separate field. It is never mixed into the attendance list. Default: true.
- `max_queries` (string): Between 1 and 5. Each query costs roughly 0.8 seconds plus a 1.3 second pause. 2 is the measured sweet spot: search engines refuse a third query from the same container almost every time, and the thi…
- `skipCache` (string): false uses the 21 day result cache. true forces a fresh look. Default: "false".
- `years` (string): Comma separated, for example 2025,2026. Events dated outside this set are still returned and flagged. Sent as a string so it works from Clay. Default: "2025,2026".
