# mcpspend

Tracks MCP tool call costs across your coding agents and lets you inspect spending directly in the chat. Useful for catching runaway token bills early.

## What it does

This server connects your client to `mcpspend.com`, letting an assistant run queries like `get_today_cost` and `list_top_tools`. Data collection happens through the companion `@mcpspend/proxy`, which wraps existing tool configurations to record latency, tool names, models, and rough token counts based on payload length.

Tool arguments and raw output bodies stay on your local disk; only aggregated metadata reaches the ingestion endpoint. Running the server requires an `MCPSPEND_API_KEY`. The free plan covers 25,000 tool executions per month without entering payment details.

## Requirements
- Needs: Node.js (commands run via npx)
- Environment variables: `MCPSPEND_API_KEY`, `MCPSPEND_ENDPOINT` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## Install

## When to use it
- check current day tool spending inside the agent conversation
- spot the most heavily invoked MCP tools across your setup
- forecast monthly budget usage before hitting billing limits
- inspect session activity without leaving the terminal

## Example prompts
- How much did my MCP tool calls cost today?
- List the top tools by invocation count from recent sessions.
- What is my projected spend for this month?
