OutSend

OutSend is a B2B prospecting platform exposed as a remote MCP server. Ask your assistant for "1,000 plumbers in Lyon with verified emails" and it runs the whole job on OutSend: - Extract local businesses by search query and geographic area, with a cost and volume estimate before launching. - Enrich any finished job: emails, social profiles, reviews, tech stack, and email deliverability checks. - Chain steps into pipelines (extract, enrich, filter, verify) and schedule recurring monitors that rerun them. - Follow progress with job status and an account event feed, preview up to 50 rows per call, and download the full CSV. Jobs are asynchronous and large results are never dumped into the chat: the assistant gets a preview plus a download link. The server runs on your own AI subscription, so there is no extra LLM cost on the OutSend side. Authentication: create an API key (osk_...) in OutSend under Settings -> API keys, then send it as Authorization: Bearer osk_.... Clients that cannot set headers can use the secret URL https://outsend.xyz/mcp/k/<your key>. Accounts are invitation-based during the alpha: https://outsend.xyz/join/mcp applies the invitation code for you.
