⭐ Back Delta MCP with a star. Click Star at the top right of this page. It takes one second, it’s free, and it helps other people who use MCP find Delta MCP before launch.

Coming soon for macOS, Windows and Linux: free, no account. Follow the launch and you’ll know the moment it’s out, with no email address: RSS, or Watch → Custom → Releases on this repository.

Decide before. See after. Go back.

1. You decide before. For each tool, choose what your AI may do alone: only read, ask before deleting or sending, or ask every time. When it asks, you see each change before and after.
2. You see what happened. Every change is recorded with its before and after, written by Delta MCP, not by your AI. It checks results in the tool when it can, and if a connection drops it checks before doing anything twice.
3. You can go back. Undo puts back what can be put back, and tells you before you click what can’t, like a message already sent.

⭐ Like what you see? A star is the simplest way to back Delta MCP. It tells us this is worth finishing.

Ctrl+Z for your AI’s work.

Every task shows each change before and after. Undo it right away, and in some cases later, by you or by your AI.

• Before and after. Changes are shown as they were and as they are now, read back from the service wherever it can be read.
• One step or the whole task. Your AI writes how to undo each step. If a later step fails, or you click Undo, they run in reverse order.
• Honest about what can’t come back. Before you click, you see what will be put back and what can’t, like a message already sent. It never says everything is undone without proof.

Automate the tasks you repeat.

Set it once. Delta MCP runs it every day, on weekdays, every Monday or every hour, at a very low cost, and your AI steps in only when the task needs thinking.

• Reports and routines. Analyze last night’s Grafana logs and send your team a report. Follow the market every morning. Close finished tickets every Friday.
• Free, or with your AI. Delta MCP runs it for free, no AI needed. When it needs analysis, your AI takes the run at the time you set, then reports, emails or acts on what it finds.
• Ask your AI to set it up. Tell your AI what to automate and it creates it in Delta MCP. You test it, sign once, and it pauses and tells you after two failures.

Measured: up to 24.1× fewer tokens

Same result, far fewer tokens. On tasks with several steps, Delta MCP uses fewer tokens, costs less and finishes as fast or faster, with the same end result, checked in the service itself. 8 scenarios, each run with and without Delta MCP, in Claude Code with Sonnet 5.5. A single one-step question costs more: the gain is on tasks with several steps.
