Know what every
MCP call costs you.
MCPSpend is the observability proxy for Model Context Protocol tools. Track tokens, attribute spend per team and customer, and ship AI to production with audit-grade visibility.
No credit card. 5-minute install. Works with Claude, OpenAI, and any MCP-compatible client.
MCP tools are eating budgets nobody is tracking.
Every team building with agents is hitting the same wall: tool calls explode in volume, costs spike unpredictably, and there's no clean way to see what's happening until the invoice lands.
Your AI costs are a black box
Vendor bills arrive a month late, mixed across teams, projects, and customers. You react instead of plan.
No attribution, no accountability
You can't answer "which customer cost us $4k last week" or "which workflow is bleeding tokens." Engineering ships blind.
Compliance has no audit trail
SOC 2, ISO 27001, internal reviews — auditors want every tool call logged, attributed, and queryable. Spreadsheets don't cut it.
Five minutes from install to first insight.
MCPSpend sits transparently between your agents and your MCP tools. No SDK changes, no proxy wars, no vendor lock-in.
Install the proxy
One npm install. Drop @mcpspend/proxy in front of your MCP server config. Five lines of code, zero changes to your agent.
npx @mcpspend/proxy add --key sk_live_...
