Claude is smart on its own.
But Claude connected to your sales stack?
That is a different animal.
MCP stands for Model Context Protocol. Sounds technical. It is not. Think of it as a universal adapter that lets Claude plug into your existing tools. Your CRM. Your enrichment platform. Your email. Your calendar.
Once connected, Claude does not just give you advice about your pipeline. It can actually look at your pipeline. It does not just suggest prospects. It can pull real prospect data from Clay. It does not guess at social signals. It reads them from Trigify.
This is where Co-Work goes from "useful AI assistant" to "autonomous sales machine."
MCP is an open standard created by Anthropic that lets AI tools talk to external data sources. It works like a bridge: on one side is Claude, on the other side is whatever tool you want to connect.
Each connection is called an MCP server. The server runs locally on your machine (your data stays private) and exposes specific tools that Claude can use.
For example, a Clay MCP server lets Claude search your Clay database, find contacts, enrich prospects, and pull company data. All from within a Co-Work conversation.
Claude Desktop now has a built-in extensions directory. This is the simplest way to add tools.
