# session_transfer Transfer an AI agent session from THIS machine to another device in one step. The session (conversation history, agent state, optionally workspace) is packaged, sent to the target device, and imported there. The user can then continue working from the target device via mobile or desktop. Supports Claude Code, Aider, Codex, Goose, Amp, OpenCode sessions. Agent View of the PolicyLayer registry record for `session_transfer`. HTML page: https://policylayer.com/tools/io-github-kivanccakmak-yaver/session-transfer ## Facts - Tool: `session_transfer` - Server: Yaver (`yaver-cli`) — https://policylayer.com/tools/io-github-kivanccakmak-yaver.md - Install: `npx -y yaver-cli` - Homepage: https://github.com/kivanccakmak/yaver.io - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 4 (2 required) - Recommended policy verdict: Rate-limited ## Parameters | Parameter | Type | Required | Description | | --- | --- | --- | --- | | `task_id` | string | yes | The task ID of the session to transfer | | `target_device` | string | yes | Target device ID or hostname prefix (from your registered devices) | | `workspace_mode` | string | no | How to transfer workspace: 'none', 'git', or 'tar'. Default: 'git'. | | `include_workspace` | boolean | no | Include workspace files (default: false) | Parameters from the server's own tool schema. ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "session_transfer", "arguments": { "task_id": "", "target_device": "" } } } ``` ## Why session_transfer is rated High This tool triggers an external multi-step operation: it packages session state (conversation history, agent state, optionally workspace), transmits it to another device, and imports it there. This is not a simple read or write — it executes a cross-device transfer operation whose effects depend on arguments (target device, session scope). From the tool's own definition: "Transfer an AI agent session from THIS machine to another device in one step... packaged, sent to the target device, and imported there" ## Use case AI agents invoke session_transfer to trigger actions in Yaver. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Yaver: ```json { "version": "1", "default": "deny", "tools": { "session_transfer": { "limits": [ { "counter": "session_transfer_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on Yaver (644) - `acl_remove_peer` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/acl-remove-peer.md - `cancel_schedule` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/cancel-schedule.md - `cloud_destroy` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/cloud-destroy.md - `companion_down` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/companion-down.md - `data_delete` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/data-delete.md - `db_push` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/db-push.md - `db_reset` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/db-reset.md - `db_restore` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/db-restore.md - `dns_flush` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/dns-flush.md - `dns_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/dns-remove.md - `docker_prune` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/docker-prune.md - `docker_rm` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/docker-rm.md - `docker_rmi` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/docker-rmi.md - `feedback_delete` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/feedback-delete.md - `forgot_password` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/forgot-password.md - `git_member_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/git-member-remove.md - `git_stash` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/git-stash.md - `guest_delete` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/guest-delete.md - `guest_revoke` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/guest-revoke.md - `jobs_cancel` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/jobs-cancel.md - `machine_onboarding_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/machine-onboarding-remove.md - `machine_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/machine-remove.md - `migrate_rollback` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/migrate-rollback.md - `models_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/models-remove.md - `monitor_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/monitor-remove.md - `phone_project_delete` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/phone-project-delete.md - `proxy_remove` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/proxy-remove.md - `relay_clear_password` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/relay-clear-password.md - `release_rollback` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/release-rollback.md - `remote_destroy` — Destructive — https://policylayer.com/tools/io-github-kivanccakmak-yaver/remote-destroy.md - …and 614 more: https://policylayer.com/tools/io-github-kivanccakmak-yaver.md ## For agents This record is a snapshot.
