Connect io.github.Bluecraft-AI/cold-email and your agent gets 6 tools, among them export_list, generate_batch, generate_sequence. It answers at https://mcp.machfive.io/mcp/{api_key} over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 10 of 10 times since 5 September 2026; the last check, on 18 October 2026, succeeded.

Description as the publisher wrote it.
| Tool | What it does |
|---|---|
export_list | 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. Inputs: list_id, format |
generate_batch | 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 Inputs: campaign_id, leads_json, email_count, list_name, email_signature, campaign_angle |
generate_sequence | 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 Inputs: campaign_id, email, name, title, company, company_website |
get_list_status | 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. Inputs: list_id |
list_campaigns | 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 JS Inputs: query |
list_lists | 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. Inputs: campaign_id, status, limit, offset |

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://mcp.machfive.io/mcp/{api_key}. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.
