Cycles: Pricing, Features & Best Use Cases

Open-source runtime authority layer that enforces budgets and action limits on autonomous AI agents before they execute.

Is Cycles right for you?

Cycles fits engineering teams running autonomous agents that need a self-hosted, open-source budget and action limiter placed before each model or tool call. Based on the vendor's documentation, not on a hands-on test.

Best for: Teams running autonomous agents in production

Also a good fit for

  • SaaS builders needing per-tenant AI spend limits

Consider another tool if self-hosting required; managed cloud is not yet available

Or if

  • Production support starts at $1,500/mo billed annually
  • Application must enforce results itself; it does not control tools directly

What is Cycles, and how does it work?

Cycles is an Apache 2.0 open-source, self-hosted service that checks budgets before an AI agent makes a model call or tool call. Applications reserve budget, and a rejected reservation lets the host skip the call, which the site presents as a way to stop runaway spend and risky actions. It ships SDKs and an MCP server with guides for Claude Desktop, Claude Code, Cursor and Windsurf, plus API and protocol references. Paid plans add support and assurance rather than features; a managed cloud is listed as planned.

How to use Cycles for enforcing a budget limit on an AI agent

Cycles documentation — screenshot of the coding AI tool, Oct 1, 2026
Cycles documentation: where the steps below come from. runcycles.io, captured Oct 1, 2026

Set up Cycles

  1. Self-host the Cycles service from the open-source repository
  2. Create a tenant and budget scope
  3. Install an SDK or the MCP server in your agent application

Example: enforcing a budget limit on an AI agent

  1. Reserve budget before each model or tool call
  2. Skip the call if the reservation is rejected
  3. Settle actual usage after the call
  4. Repeat per tenant or workflow scope

Review and export the result

  1. Exhaust a small test budget and confirm the next call is blocked
  2. Inspect recorded events for reserved vs settled amounts
