Overview

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.

Key features of Mcpspend

  • Transparent stdio proxy intercepting every tools/call
  • Auto-detects MCP clients on the machine (Claude Desktop, Cursor, Windsurf, etc.)
  • Dashboard shows top-N tools by cost with gradient bars
  • Sessions view with drill-down into specific agent runs
  • Budget projections with Slack alerts at 50/80/100%
  • Per-project cost allocation by labeling MCP servers
  • Privacy-by-design: never sends tool arguments, responses, or file contents
  • 25,000 calls/month on the free tier

Use cases of Mcpspend

  • Identify which MCP tool is consuming the most budget across multiple agents
  • Track the cost of a single Claude Code or Cursor session in detail
  • Project monthly spending and get alerted before exceeding a budget
  • Allocate costs to specific projects by labeling MCP servers
