B2B lead search in ChatGPT via MCP
Connect as a remote MCP connector — no API key to paste anywhere.
B2BLeads runs its own remote Streamable-HTTP MCP endpoint at api.b2bleadsapi.com/mcp, built specifically for ChatGPT's Connectors/Plugin flow — you sign in with OAuth 2.1 (PKCE) instead of copying an API key into a text box.
Once connected, ChatGPT can call search_leads, search_leads_advanced, list_industries, and find_email directly inside a conversation — ask it to find contacts in a city and industry, or look up a contact email for a specific website, and it calls the tool live rather than guessing.
The connector is read-mostly by design (no delete/write access to your account), and it enforces the same plan limits as the REST API and dashboard, so usage from ChatGPT counts against the same quota either way.
- OAuth 2.1 + PKCE sign-in — no API key to copy-paste
- Streamable-HTTP transport, no local install
- search_leads, search_leads_advanced, list_industries, find_email available remotely
- Same plan quota and rate limits as the API/dashboard
