Mcpspend について

MCPSpend is the first cost-observability platform built natively for MCP. One CLI command wraps yourexisting MCP servers across Claude Desktop, Cursor, Windsurf, VS Code, and Claude Code — zero SDKchanges. Per-tool / per-project cost attribution, $ budget alerts via email + Slack

概要

What is Mcpspend?

MCPSpend is a cost-observability tool for the Model Context Protocol (MCP). It uses a transparent stdio proxy to record metadata on every tool call—server name, tool name, latency, success/error, and estimated token usage—and streams that data to a dashboard for cost analysis. It is built for developers running MCP clients like Claude Desktop, Cursor, Windsurf, VS Code, and Claude Code who need to understand which tool calls drive their LLM bills.

How to use Mcpspend?

Run the single command npx @mcpspend/proxy add in the terminal. The CLI auto-detects every MCP client on the machine, lists the servers it found, asks for confirmation, then rewrites the configuration files in-place (with .mcpspend.bak backups) to wrap each server with the transparent proxy. The proxy then streams metadata to api.mcpspend.com/v1/ingest authenticated with your API key.
