ai-economics-mcp
MCP server for AI economics. Gives Claude, Cursor and any MCP client 12 calculators for the questions that decide AI budgets: what tokens cost, what queries burn, and whether agent work can be proven.
Listed in the official MCP Registry as pl.piszczek/ai-economics (domain-verified). Wraps the free piszczek.pl/tools API — no key, no sign-up,
stateless (inputs are never stored). The math is the same as the interactive calculators.
Install
Claude Desktop / Claude Code (claude_desktop_config.json / .mcp.json):
{
"mcpServers": {
"ai-economics": {
"command": "npx",
"args": ["-y", "@michalpiszczek/ai-economics-mcp"]
}
}
}
Claude Code one-liner:
claude mcp add ai-economics -- npx -y @michalpiszczek/ai-economics-mcp
Tools
| Tool | Answers |
|---|---|
token_cost | What do 1M tokens cost per month across GPT, Claude, Gemini, DeepSeek? |
context_window | How many tokens is 50 pages, does it fit, what does carrying it cost? |
agent_hour | What does one hour of an AI agent cost, fully loaded with verification? |
model_routing | How much does routing to a cheaper tier save per year? |
llm_energy | How much electricity does an AI query use? |
joules_per_verified_task | Which model is most efficient per task that actually passes? |
token_burn | What does org-wide token burn cost in money, kWh, CO₂? |
humanoid_energy | How long can a humanoid robot run per charge? |
proof_adjusted_autonomy | How autonomous is a "90% autonomous" agent once proof is required? |
revocation_exposure | How long does a revoked token keep working across your stack? |
verification_bottleneck | How many AI agents can a human review team absorb? |
proof_debt | What does unverified AI work cost over time? |
All parameters are optional; defaults mirror the interactive calculators. Every response
includes result, formula, interpretation and a ready-to-quote cite_as sentence.
Example
You: how autonomous is our agent really? it completes 90% alone, evidence for 95%, 80% independently validated, 90% on time
Claude (calls
proof_adjusted_autonomy): PAA = 61.6% — supervised autonomy. The gap vs the claimed 90% is 28.4 pp, and the biggest lever is independent validation…
