Plain-Markdown agent instructions
Write the agent’s job in Markdown instead of filling out a rigid workflow builder. The product presents this as a way to create specialized agents for sales, support, growth, engineering, and other repeatable work.
Cronloop
Cronloop is a platform for running AI agents on recurring schedules. It lets you define the job in plain Markdown, run agents with Codex or Claude Code, and monitor each run live from the app or via ChatGPT and Claude.
What Cronloop does
Cronloop is a platform for running AI agents on a schedule. Instead of asking an agent to do a one-off task, you describe a recurring job in plain Markdown, choose Codex or Claude Code, and let it keep running in a loop.
The product is built for work that repeats over time: prospect outreach, support triage, content updates, issue handling, and similar operational tasks. Cronloop shows each run live, keeps a memory between runs, and can be used directly in the Cronloop app or through a hosted MCP server connected to ChatGPT or Claude.
Features
Model and provider choice
Choose between Codex and Claude Code for the agent runtime. Cronloop says it works with your existing subscriptions or with provider API keys.
Recurring schedules
Schedule runs from every five minutes to once a week. The site also shows examples such as every 30 minutes, every hour, and every morning.
Durable agent memory
Each agent keeps a memory between runs, and the MCP tools expose read, write, and delete actions for that durable memory.
Live runs and run history
Watch each run live and review the recent history afterward. The dashboard examples show in-progress status, skipped runs, completed work, and timestamps for past runs.
Hosted MCP access and tool integrations
Connect agents to common tools through a broad catalog and through a hosted MCP server. The source lists apps and systems such as Gmail, HubSpot, Notion, GitHub, Zendesk, Google Calendar, and many others.
Use cases
Outbound prospecting
Set an agent to find new prospects on a schedule, enrich them, send outreach, and log results to tools like HubSpot. The home page shows a prospect-outreach agent running every 30 minutes.
Support triage
Use an agent to read new support tickets, reply from help docs, and escalate sensitive cases to a human. The MCP page gives this as a concrete example for Zendesk and similar support workflows.
Content and SEO maintenance
Have an agent review fresh performance data, draft content updates, and publish changes to a CMS on a recurring cadence. The home page frames this as a way to grow organic traffic with scheduled updates.
Engineering task automation
Pick up assigned engineering issues, write fixes and tests, and open pull requests on a schedule. The source positions this as a recurring automation for development work tied to systems like GitHub and issue trackers.
Assistant-driven operations
Ask an assistant connected through MCP to create agents, pause runs, review failures, or update memory without opening the dashboard. This fits teams that already work inside ChatGPT or Claude.
Pros and Cons
Pros
- Supports recurring agents rather than only one-time prompts.
- Lets you describe work in plain Markdown, which is a low-friction way to define a job.
- Includes live run visibility and run history so you can see what happened during execution.
- Agents retain memory between runs, which is useful for ongoing workflows.
- Can be accessed from ChatGPT or Claude through a hosted MCP server with OAuth sign-in.
Cons
- The public pages do not provide a complete pricing or limits breakdown beyond the Free and Pro plan highlights.
- Integration details are broad in the source, but the site does not document every third-party connection or setup requirement in depth.
- The pages emphasize operational workflows, but they do not cover many team, admin, or governance features in detail.
