Node.js
The fastest way to run it: one npx command, no clone required.
b2bleads-mcp is published to npm, so any MCP client that can launch a local command — Claude Desktop, Claude Code, Cursor, Windsurf, and most desktop agents — can start it with a single npx invocation and an API key. There's nothing to build or install ahead of time.
The package is the reference stdio implementation of the server: the same five tools, the same B2BLeads account behind them, just run as a plain child process instead of over HTTP.
By default npx always resolves the latest published version, so tool updates (like the recent addition of find_email) reach every client automatically the next time it restarts — pin a version in the config if you'd rather control that yourself.
- npx -y b2bleads-mcp — nothing to install ahead of time
- Config is a 6-line JSON block (see below)
- Reads B2BLEADS_API_KEY / B2BLEADS_API_URL from env
- Works with any client that supports the stdio MCP transport
