bring your own AI assistant

Drive your lead lists from your AI assistant.

Sourcerer ships an MCP (Model Context Protocol) server. Connect an MCP-compatible client and work your lists from inside the assistant you already use.

01 / mcp

Your assistant, on your lists.

Connect over MCP and your assistant can browse lists, read leads and their profiles, see the evidence behind a score, and curate — all in plain language, without leaving the assistant.

  • Browse your lead lists
  • Read the leads in a list
  • Open a lead's full profile
  • See why a lead scored
  • Keep or drop a lead
  • Comment on a lead
  • Refine the list's criteria
  • Disconnect anytime
02 / safe

Read and safe curation only.

The connection reads and curates — keep/drop, comments, criteria. It can't spend your credits or kick off a paid run. Sourcing, enrichment, and email stay in your hands, inside the app.

read curate credit-safe
03 / clients

Works with your MCP client.

Any MCP-compatible client connects — like Claude. If your assistant speaks MCP, it works with Sourcerer.
