MCPSpend MCP server

See what your AI tool calls actually cost, broken down by tool, project, and customer.

Analytics For it and development Monitoring

MCPSpend keeps an eye on how much your AI tool calls are costing you. It sits quietly between your AI app and the tools it uses, and adds up the spend as you go. It is handy for anyone who uses AI agents for work and wants to know where the money goes.

What is an MCP server? The 30-second version

On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to another service. This one connects your AI to MCPSpend, so it can look up your usage and cost numbers for you. You just ask in plain words, and the helper fetches the answer from MCPSpend.

What this MCP server does

You ask your AI something like how much you spent today. Your AI passes that question to this helper. The helper talks to MCPSpend, which has been quietly recording the cost of every tool call your AI made. MCPSpend sends back the numbers, and your AI shows them to you right in the chat. It also works the other way: a small proxy watches your tool calls and streams the costs to your dashboard.

Flow diagram: you ask your AI “How much did my AI tools cost me today?”, the MCPSpend MCP server connects it to MCPSpend, and you get back today's total cost.

“How much did my AI tools cost me today?”
“Which tool has been the most expensive this week?”
“Show me the spend for the Acme project this month.”
“List my top five tools by cost.”

What it gives back to you

You get back plain numbers and short lists in the chat. For example, a total for the day, a ranked list of your most expensive tools, or a breakdown per project or customer. If you ask for a CSV, you get a file you can open in a spreadsheet.

Before you start

What you need

A free MCPSpend account (25,000 tool calls per month, no card needed)
An MCPSpend API key, which looks like mcps_live_xxx (the site gives you one when you sign up)
Node.js installed on your computer if you use the one-command installer

Good to know

The proxy watches your tool calls and sends usage details to MCPSpend, so if you handle sensitive work, read their privacy page first; they say tool arguments and responses never leave your machine.
