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 →
export_list Export List ~90
Download the generated email sequences for a COMPLETED list. Only call this AFTER get_list_status shows processing_status = 'completed'. If the list is not yet completed, you'll get a 409 error — poll first.
| Name | Type | Req | Description |
|---|---|---|---|
| format | string | – | Output format: 'json' (structured data) or 'csv' (raw CSV for sending tools). |
| list_id | string | yes | List UUID to export. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
generate_batch Generate Batch ~236
Submit multiple leads for batch email sequence generation (ASYNC). Returns IMMEDIATELY with a list_id. Processing runs in the background. After calling this, poll get_list_status every 15-30 seconds until processing_status is 'completed' or 'failed', then call export_list. You must have a campaign_id first. Call list_campaigns if you don't have one.
| Name | Type | Req | Description |
|---|---|---|---|
| approved_ctas | string | – | Comma-separated CTAs. Omit to use campaign defaults. |
| campaign_angle | string | – | Additional context/angle for personalization. |
| campaign_id | string | yes | Campaign UUID from list_campaigns. |
| email_count | integer | – | Number of emails per lead, 1-5. |

generate_sequence Generate Email Sequence ~302
Generate a personalized cold email sequence for ONE lead. This is SYNCHRONOUS — the request takes 3-10 minutes because MachFive researches the prospect and crafts unique emails. Do NOT retry if it seems slow; wait for the response. You must have a campaign_id first. Call list_campaigns if you don't have one. If the request times out, use the returned list_id with get_list_status and export_list to recover results.
| Name | Type | Req | Description |
|---|---|---|---|
| approved_ctas | string | – | Comma-separated CTAs, e.g. 'Direct Meeting CTA, Lead Magnet CTA'. Omit to use campaign defaults. |
| campaign_angle | string | – | Additional context/angle for personalization. |
| campaign_id | string | yes | Campaign UUID from list_campaigns. |
| company | string | – | Lead's company name (improves personalization). |

get_list_status Get List Status ~79
Check the processing status of a lead list. Use this to POLL after calling generate_batch. Call every 15-30 seconds until processing_status is 'completed' or 'failed'. When completed, call export_list. When failed, submit a new batch.
| Name | Type | Req | Description |
|---|---|---|---|
| list_id | string | yes | List UUID from generate_batch or generate_sequence response. |
| Name | Type | Req | Description |
|---|---|---|---|
| result | string | yes | – |
No examples provided.
list_campaigns List Campaigns ~108
List campaigns in the user's MachFive workspace. CALL THIS FIRST before generate_sequence or generate_batch — you need a campaign ID to generate emails. If the user hasn't specified a campaign, call this and ask them to pick one. Returns JSON array of campaigns with id, name, and created_at. Use the 'id' field as campaign_id in generate calls.
| Name | Type | Req | Description |
|---|---|---|---|
| query | string | – | Search string to filter campaigns by name (case-insensitive substring match). Leave empty to list all. |
