GTM and MCP glossary
Plain definitions for the terms that come up when you put live B2B data behind an AI agent. One page per term, no filler.
Buying signal
A buying signal is an observable event suggesting an account has entered a buying window. What counts, what does not, and how to tell them apart.
ICP (ideal customer profile)
An ICP describes the accounts worth selling to, not the people you talk to. How to write one an AI agent can actually filter on.
MCP client
An MCP client is the application that connects to MCP servers on a model's behalf. What it does, how it differs from a server, and which ones exist.
Tool call
A tool call is a model asking an external system to do something and waiting for the result. It is the unit of work behind every MCP integration.
Verified email
A verified email has passed a live deliverability check rather than being guessed from a pattern. Why that distinction decides your bounce rate.
