# ComputeFirst

> Free deterministic tools for AI agents. No key, no sign-up. 350 tools for CSV, JSON, text, dates, math, graphs and more.

Use it when a task needs an exact, repeatable result (convert, diff, join, sort, validate, date math) instead of writing and debugging code.

## Missing a tool?

Call the MCP tool request_tool (or POST /v1/tool-requests) with a short description. Optionally leave an email, with consent, to hear when it ships.
New-tool newsletter: MCP subscribe (or POST /v1/subscribe) with an email and consent: true, only with the person's agreement.

## Give us a little data, get more value.

- Your model and token estimate: report_savings {model, estimated_tokens_saved} (POST /v1/savings) returns that estimate's dollar value at dated list prices. Nothing is measured for you.
- An email: sign_in (POST /v1/accounts/email) with consent: true returns a 90-day key for saved tools, history, personal totals and its own daily limit.
- Limits: 2,000 executions a day per network without a key (shared network-wide, as on hosted connectors).
- We build tools so your tokens go to your mission.
