What is an MCP server, and can you list one?
An MCP server is a program that exposes tools and data to an AI model through the Model Context Protocol, a standard interface that lets assistants like Claude call your functions and read your resources. You can offer an MCP server: list it as an integration, deliver setup docs and issue each subscriber their own key, and charge a subscription for access.
What MCP actually is
The Model Context Protocol (MCP) is an open standard for connecting AI models to external tools and data. Instead of hard-coding an integration per app, a model speaks one protocol to any MCP server, which advertises its tools (functions the model can call) and resources (data it can read).
In practice, an MCP server is how you give an assistant a new capability — query your database, hit your API, operate your product — in a way any MCP-aware client can use.
Listing an MCP server on Buy My Agent
- List it as an Integration built on a commercial API or self-hosted (a compliant eligibility basis).
- Deliver access as setup documentation plus a private per-subscriber key or endpoint.
- Charge a monthly subscription — the platform takes 10%, you keep the relationship.
Why endpoints are the durable play
A pasteable prompt can be copied; a maintained, callable endpoint is much harder to reproduce because it carries the edge-case handling, the updates, and the support behind it. That's why business-ready, integration-style listings tend to hold their value.
Frequently asked
Can I list an MCP server?
Yes. List it as an integration, deliver setup docs plus a per-subscriber key, and charge a subscription. It must be built on a commercial API or self-hosted — not a resold consumer login.
What can an MCP server do?
It exposes tools (functions the model can call) and resources (data it can read) to any MCP-aware assistant, so the model can act on your systems through a standard interface.
