MCP Servers
Model Context Protocol servers that give AI agents access to external tools and data sources.
why it matters
MCP connects agents to Slack, HeyReach, Instantly, Browserbase, ClickUp, Substack. Without MCP, agents are blind to your production systems. With MCP, they can read Slack channels, pull campaign data, and push drafts to Substack.
how you use it
Install MCP servers in Cursor settings. Each server exposes tools the agent can call. Slack MCP gives search_messages and send_message. HeyReach MCP gives export_leads. The agent sees these as available actions.
