The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
poll_sequencer_events Poll sequencer events ~530
Read replies, bounces, unsubscribes, meetings booked, interest changes, and LinkedIn replies from your own Instantly, Smartlead, HeyReach, and lemlist accounts for a time window. Returns one flat row per event (vendor, event type, time, lead email and name, company, campaign, reply text where the vendor returns it) plus one free run summary row with counts and the status of each vendor. Vendor keys are read from this server's environment (INSTANTLY_API_KEY, SMARTLEAD_API_KEY, HEYREACH_API_KEY, LEMLIST_API_KEY); vendors with no key are skipped. Read-only: it never creates, edits, pauses, or sends anything in a sequencer. A run that does not succeed is returned as an error with its run ID. Requires an APIFY_TOKEN and is billed per event row.
| Name | Type | Req | Description |
|---|---|---|---|
| event_types | array | – | Which events to return. Default: reply, linkedin_reply, bounce, unsubscribe, meeting_booked, interested, connection_accepted. |
| heyreach_campaign_ids | array | – | Read only these HeyReach campaigns (numeric ids). Empty: all campaigns. |
| instantly_campaign_ids | array | – | Read only these Instantly campaigns (UUIDs). Empty: all campaigns. |

| max_charge_usd | string | – | Optional. The run stops before a charge that would pass this amount. |
| max_events | string | – | Event rows per run, oldest first, up to 50000. Each event row is billed. Default 5000. |
| max_pages_per_query | string | – | Pages of 100 records per vendor query, 1 to 100. Default 20. |
| only_new | string | – | Skip events an earlier run already returned (free). Default true. |
