Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

cost
cost_report
Cost per run, per tool, per model and per day. Without an API key pass run_id (one run). With a key: everything on that key. Free shows 7 days, Pro 30.
log
log_costs
Log what your agent's model and tool calls cost, then get the running total for the run and for today. Pass events (one per call, up to 500) or an OpenTelemetry OTLP/JSON trace export as otel (gen_ai.usage.input_tokens / output_tokens / gen_ai.request.model are read; trace id becomes run_id). Give cost_usd per call, or tokens plus your own per-million prices; nothing is guessed. Optional caps: run_cap_usd and daily_cap_usd. Free watch-only returns would_alert when a cap is crossed; Pro posts one alert per day to alert_webhook. Never blocks or changes your agent.
usage
usage_and_upgrade
Show today's usage for your key or IP and the $9/month upgrade link. Free tier: 500 calls/day. Not metered.
weekly
weekly_report
Plain-English summary of the last 7 days of spend: total, top runs, top tools, top models, busiest day. Read-only; sends nothing. Needs a free API key.

Agent Cost Log — questions

Answers built from our own checks of this server.

What can Agent Cost Log do?
It exposes 4 tools, read directly from the server on our last check. Among them: cost_report, log_costs, usage_and_upgrade, weekly_report. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Agent Cost Log working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 74 of 75 checks got a reply (98.7%), average response time 270 ms. The bar chart above shows every period we have measured.
How do I connect Agent Cost Log?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Agent Cost Log need an API key?
No. Agent Cost Log completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Agent Cost Log?
It answers our handshake in 270 ms on average, which is faster than 48% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
