Brakes for AI agents.

Agents now hold your API keys and your wallet. Burnrate puts the limits outside the agent — hard budgets, action policies and on-chain enforcement — where the agent can't talk its way past them.

The Burnrate band in Claude Code: 5-hour and 7-day limit meters, context fill, cache hit rate, what fills the context, and guard warnings

Agents spend. Nothing stops them.

The only controls today are a dashboard you read after the bill arrives, or a system prompt the agent is free to ignore.

Limits hit mid-taskA coding agent burns the 5-hour quota on one repo-wide scan and stalls the rest of your day.
Keys drained overnightA loop with a paid API key and no budget is a surprise invoice waiting to happen.
Funds moved, no breakerA trading agent swaps into a token that rugs an hour later. There was no one to say no.

One policy, three layers.

The same idea everywhere an agent can spend: the limit lives outside the agent.

Burnrate for Claude Code

A plugin and MCP server that make the agent see — and respect — its own limits.

  • Live 5h / 7d limit band and context breakdown
  • Cache-miss watchdog with the likely cause
  • Near the cap: blocks subagents and wide scans, asks for short answers
Live · free and open source

Burnrate Gateway

An OpenAI-compatible proxy that gives every agent and every customer its own key and its own budget.

  • Per-key USD budgets and rate limits
  • Over budget means refused — before the provider is called
  • A ledger of every call, in tokens and dollars
Prototype · early access
On-chain

Burnrate Vault

A policy vault for AI trading agents on Solana. An AI risk oracle scores the token, publishes the score on-chain, and the vault refuses the swap.

  • Rug-pull scorer, ROC AUC 0.90 on 2,350 held-out tokens
  • Enforced by a smart contract, not a prompt

“I run agents all day and kept hitting the same wall: they spend with no brakes. Every Burnrate tool started as something I needed that week.” Talap Kenzhebaev, founder — AI engineer, previously built and sold an IT media and HR-tech platform
