MCP tools · 6 exposed · ~924 tokens

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 →

Tool Tokens
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.

NameTypeReqDescription
formatstring–Output format: 'json' (structured data) or 'csv' (raw CSV for sending tools).
list_idstringyesList UUID to export.
NameTypeReqDescription
resultstringyes–

No examples provided.

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.

NameTypeReqDescription
approved_ctasstring–Comma-separated CTAs. Omit to use campaign defaults.
campaign_anglestring–Additional context/angle for personalization.
campaign_idstringyesCampaign UUID from list_campaigns.
email_countinteger–Number of emails per lead, 1-5.
email_signaturestring–Signature appended to each email.
leads_jsonstringyesJSON array of lead objects. Each MUST have "email". Optional: name, title, company, company_website, linkedin_url. Example: '[{"email":"jane@acme.com","name":"Jane Doe"}]'
list_namestring–Display name for this batch in MachFive UI.
NameTypeReqDescription
resultstringyes–

No examples provided.

generate_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.

NameTypeReqDescription
approved_ctasstring–Comma-separated CTAs, e.g. 'Direct Meeting CTA, Lead Magnet CTA'. Omit to use campaign defaults.
campaign_anglestring–Additional context/angle for personalization.
campaign_idstringyesCampaign UUID from list_campaigns.
companystring–Lead's company name (improves personalization).
company_websitestring–Company URL for AI research.
emailstringyesLead's email address (REQUIRED).
email_countinteger–Number of emails in sequence, 1-5.
email_signaturestring–Signature appended to each email.
linkedin_urlstring–LinkedIn profile URL for deeper personalization.
list_namestring–Display name for this list in MachFive UI.
namestring–Lead's full name (improves personalization).
titlestring–Lead's job title (improves personalization).
NameTypeReqDescription
resultstringyes–

No examples provided.

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.

NameTypeReqDescription
list_idstringyesList UUID from generate_batch or generate_sequence response.
NameTypeReqDescription
resultstringyes–

No examples provided.

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.

NameTypeReqDescription
querystring–Search string to filter campaigns by name (case-insensitive substring match). Leave empty to list all.
NameTypeReqDescription
resultstringyes–

No examples provided.

list_lists ~109

List lead lists (batch jobs) in the user's MachFive workspace. Useful for browsing past batches, checking what's in progress, or finding a list_id to export. Results are ordered newest first.

NameTypeReqDescription
campaign_idstring–Filter by campaign UUID.
limitinteger–Max results to return, 1-100.
offsetinteger–Pagination offset.
statusstring–Filter by processing status: 'pending', 'processing', 'completed', or 'failed'.
