Mcpspend
If you're running MCP tools across Cursor, Claude Desktop, Windsurf, or VS Code and want to know what they're actually costing you, this server turns that telemetry into queryable data. It exposes tools like get_today_cost, list_top_tools, and recent sessions so your agent can pull usage stats, budget projections, and per-tool breakdowns without leaving the conversation. The underlying proxy wraps your existing MCP servers and streams metrics to mcpspend.com. You get 25,000 tool calls free per month. Reach for this when you're iterating on agent workflows and need to spot which tools are burning tokens or when you want programmatic access to cost data instead of opening a dashboard.
