## What it does

Leadbase MCP server connects your development environment to a hosted research workspace over HTTP. You specify criteria such as geography or industry focus in plain text. The assistant queries target accounts and writes findings into persistent tables.

Entries arrive as separate rows with web links for verification. The sheet exports directly to CSV. You can also evaluate an entire column at once using custom qualification questions.

Connection requires an active Leadbase account authenticated via OAuth. Each new workspace receives 200 complimentary credits.
