Emailwarmup MCP Server

BobWork Email Warm-up MCP server

Remote MCP server for BobWork Email Warm-up: warm up any mailbox (Gmail, Google Workspace, Microsoft 365, Zoho, or any IMAP/SMTP), read inbox placement and spam rate, check SPF/DKIM/DMARC, and run cold email campaigns from your own mailboxes. Built so an AI agent can do the whole job for its human: sign up, connect mailboxes, start sending, and get a checkout link when payment is needed.

This repository holds the docs and the registry file. The server itself is hosted, so there is nothing to install or run.

• Endpoint: https://app-emailwarmup.bobwork.ai/mcp (Streamable HTTP)
• Auth: Authorization: Bearer bwk_...
• REST API: https://app-emailwarmup.bobwork.ai/api/v1 (OpenAPI)
• Agent guide: llms-full.txt

Get an API key with no browser

An agent can create the account for its human. The human only has to read one code from their inbox.

curl -X POST https://app-emailwarmup.bobwork.ai/api/v1/signup/code \
  -H "Content-Type: application/json" -d '{"email": "you@company.com"}'
# -> {"nonce": "..."}; a 6-digit code is emailed to you@company.com

curl -X POST https://app-emailwarmup.bobwork.ai/api/v1/signup/verify \
  -H "Content-Type: application/json" -d '{"nonce": "...", "code": "123456"}'
# -> {"api_key": "bwk_..."}  (shown once)

Or sign in at https://app-emailwarmup.bobwork.ai/login and create a key under API.
