Your Agent Can Use Any Tool, and Be One

Model Context Protocol is not the flashiest thing in AI, and that is exactly why it matters. It is plumbing. A shared way for an agent to call a tool, and for a tool to describe itself to any agent. Once the plumbing is standard, the interesting things connect without custom glue.

Direction one: your agent uses tools

Wire an MCP server or a custom function into your agent and it can reach your CRM, your inventory, your internal systems, mid-conversation. The agent stops being a closed box that only knows its training and becomes a coworker who can look things up and act on them in real time.

Direction two: your agent is a tool

This is the part people miss. Every agent you build can itself be exposed as an MCP tool that Claude, or any other agent, can call. Your support agent becomes a capability other software can invoke. Your product knowledge becomes an endpoint.

When your agent can both use tools and be one, it stops being an app you own and starts being a node in a network.

The commercial half

If your agent is a tool other agents call, the obvious next question is: can it get paid for that? Yes. Attach a price to the capability and collect automatically each time another agent uses it, per call or per resolved outcome. That is the "agents pay you" modality inside the payments layer, and it turns a support cost center into something that can earn.

Why standards win

Betting on one vendor's integration format is how you end up rebuilding everything when the vendor changes. Betting on an open protocol means every new MCP-native tool works with your agent the day it ships. MCP support runs in both directions on the platform today, and it is the connection we would build on first.
