Working state for coding agents

Continue where your AI agent left off

When a session dies — usage limit, crash, or you switch from Claude Code to Cursor — the plan, the files, the failed attempts, and the next action should still be there. CarryOn keeps that handoff and resumes it in the next agent.

Start free

Free includes 3 handoffs a month. No card. A guest can open one demo handoff first.

Usage limit

Claude Code or Codex stops mid-edit. The plan was in the thread, and the thread is gone.

Tool switch

You open Cursor to finish what Codex started. The new agent greets you like the repo is new.

Failed attempts

The next session retries the approach that already broke the build, because nobody wrote down why.

How it works

A handoff, not another memory database.

01
Capture
Your agent calls save_handoff, or you paste the working state, the moment the session is about to die.
02
Keep
CarryOn stores one actionable handoff: goal, plan, touched files, failed attempts, and the next action.
03
Resume
Copy the resume prompt, or let the next agent call get_handoff. It continues instead of rediscovering the task.

MCP

Cursor and Claude call CarryOn directly.

Add the remote MCP server with your API key. The tools are save_handoff, list_handoffs, get_handoff, and format_resume_prompt. Tell the agent to save a handoff before it stops.
