Claude Checkpoint MCP runs on your own machine — the client starts it, so there is no endpoint to ping. Last commit 7 Nov 2026.
MCP server that checkpoints Claude Code session context to survive crashes and token limits
Today is the operative word: we check Claude Checkpoint MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
claude mcp add claude-checkpoint-mcp -- npx -y session-checkpoint-mcp
{
"mcpServers": {
"claude-checkpoint-mcp": {
"command": "npx",
"args": [
"-y",
"session-checkpoint-mcp"
]
}

Optional settings from the registry entry, left out of the block above:
CHECKPOINT_PROJECT_ROOT (Optional. Absolute path of the default project to checkpoint, used when the client has no current project (e.g. Claude Desktop). A projectRoot argument on a tool call takes precedence), CLAUDE_CODE_SESSION_ID (Set automatically by Claude Code; do not set it yourself. Selects the per-session checkpoint file (.claude-checkpoints/<session-id>.json). Without it the server uses the shared .claude-checkpoint file).
