Changes things 2Claude Code: ask
  • generate_batchSubmit multiple leads for batch email sequence generation (ASYNC).No findings

    Why it is in this group

    • The name "generate_batch" says "generate": a word for a change.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "generate_sequence" says "generate": a word for a change.
    Description, as the server wrote it
    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.

  • export_listDownload the generated email sequences for a COMPLETED list.No findings

    Why it is in this group

    • The name "export_list" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "get_list_status" says "get": a word for reading.
    Description, as the server wrote it
    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.

  • list_campaignsList campaigns in the user's MachFive workspace.No findings

    Why it is in this group

    • The name "list_campaigns" says "list": a word for reading.
    Description, as the server wrote it
    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.

    Why it is in this group

    • The name "list_lists" says "list": a word for reading.
    Description, as the server wrote it
    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.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
