MCPSpend is the first cost-observability platform built natively for the Model Context Protocol (MCP). One CLI command wraps every MCP server across Claude Desktop, Cursor, Windsurf, VS Code and Claude Code; the hosted dashboard shows per-tool, per-project, per-end-customer spend in real time. Free tier 25K calls/month forever; EU-hosted, GDPR-ready.
Existing AI observability (Helicone, Langfuse, PostHog) sees the LLM call. None of them see the MCP tool layer where agents spend most of their time and money. MCPSpend fills that gap with zero SDK changes — one CLI command wraps the user's existing MCP servers, even inside closed IDEs like Cursor and Claude Desktop where SDK-wrap tools can't reach. Built by a solo Romanian founder, open-source proxy on npm, listed on the official MCP Registry and Smithery, scored #1 of 11 in SEETO AI's competitive analysis (100/100).

Andrei Sirbu is the solo founder and engineer of MCPSpend. Based in Bucharest, Romania, with a background in software engineering. He built MCPSpend after his own Claude Desktop and Cursor bills kept surprising him — and discovered no existing observability tool could tell him which MCP tool was responsible.
“Existing AI cost tools see the LLM call. We see the layer underneath — every MCP tool the agent invoked, what each one cost, which project it belonged to. That's where most of the money actually goes.”
“One CLI command and the proxy is running across every MCP client you have. Zero SDK changes, zero code edits. It just slots in.”
“We're an indie team and we don't hide behind marketing copy. The free tier is 25,000 tool calls — that's a heavy solo dev for a month. We'd rather have you use it than charge you to try it.”
