Hand off AI work with a signed Verification Receipt — an independent verifier proves it runs.

Overview

AI-generated overview

Baton seals AI work into encrypted handoff capsules and lets an independent verifier replay it and issue a server-signed verification receipt.

What you can do
Seal work into a handoff code, receive and continue it, diff two snapshots, revoke codes (handoff tools). Run verification plans, issue signed receipts from observed end-to-end evidence, and consolidate many handoffs into a trust-tiered board (verify tools). Create and manage persistent team rooms with invite codes, messaging, inbox, kick, approve and close (room tools). Track a private task DAG, bind Git commit/diff/test evidence, and record provider/model/task costs (operations tools). Store, search and delete encrypted cross-session memories, and register MCP endpoints and agent profiles with receipt-based reputation (network tools). Manage a free account, plan limits and paid upgrades.
When to use it
Useful when AI-produced work is handed between people, teams or different models and the receiver needs proof it actually runs, not just that a build passed. Also fits outsourced-to-in-house or team-to-team transitions where observed evidence matters.
Requirements
Runs as a remote Streamable HTTP endpoint or locally via the npm package baton-mcp over stdio (Node.js). A free account can be created in-band; the returned api_key goes in the MCP client Authorization header or is passed to baton_pass. Paid plans require a crypto transfer of USDT/USDC on Tron or BSC and a transaction hash.
Before you install
Handoff bodies are encrypted with a code-derived key, but the hosted service stores ciphertext, metadata, task, Git and cost facts. Inbound capsules and messages are returned as untrusted data and may carry prompt injection. Paid upgrades involve sending USDT/USDC to a wallet and submitting a transaction hash. Room owners can kick members and close rooms, destroying rooms, codes and messages. Verification receipts are only meaningful with observed end-to-end evidence.

Installation

In SourceWeft

  1. Open Baton in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.vinsenzo83%2Fbaton/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

README

🏃 BATON

Hand off AI work — with a receipt.

An AI did the work. How does the next person — or the next AI — know it actually works, not just that the build passed? BATON seals a unit of AI work into a portable capsule, and an independent verifier replays it and issues a server-signed Verification Receipt. The receiver trusts observed evidence, not a claim.

Never trust an agent handoff without a receipt.

BATON is a standard MCP (Model Context Protocol) server — any MCP-capable tool (Claude Code, Codex CLI, Gemini CLI, Cursor …) connects with one URL. The producer and the verifier can be different models, machines, and people.

Why this, and not the dozen orchestration tools?

Running Claude + Codex + Gemini together (swarms, rooms, agent messaging) is a crowded space. BATON isn't that. The one thing almost nobody does: bind the handoff artifact to independent execution evidence as a single, forgeable-proof trust unit. That's the receipt.

Claude did the work   ↓  baton_pass  → sealed capsule (BTN-H-…)Codex / a teammate receives it   ↓  baton_verify → replay in a clean env, observe the real flow   ↓🕸️ VERIFIED — signed receipt: who verified · what was observed · in what env · with what artifacts   ↓trust  (or reject)

The real buyer isn't "me switching Claude→Codex" (just re-read the repo). It's outsourcer→in-house, leaver→joiner, KO team→US team — where "an AI made this, does it really work?" is a question worth paying to answer.

The receipt (the differentiator)

baton_verify doesn't return a ✅ sticker. It returns a signed record:

json
{  "kind": "baton.verification-receipt/v1",  "capsule": "BTN-H-…",              // the handoff this verifies  "verifier": "receiver-spider",    // WHO verified — independent of the producer  "environment": { "os": "ubuntu-24.04", "node": "24.2" },  "observed": [{ "claim": "payment succeeds", "observed": true,                 "detail": "POST /pay 200 + order row +1" }],  "artifacts": ["playwright.trace.zip", "network.har"],  "verdict": "verified",  "signature": "…hmac-sha256…"       // server-signed → tamper the verdict, break the sig}

Flip verdict to "verified" without re-signing and the badge is refused. A passing build never earns verified on its own — only observed E2E does (this is what catches a silent upsert that returns 200 but writes nothing).

Operationsbaton_task_* baton_git_* baton_cost_*Cycle-safe private task DAG, Git commit/diff/test evidence binding, and idempotent provider/model/task cost ledger

Operations dashboard: /ops.html. It stores only task metadata, Git evidence, and cost facts; BATON never asks for repository credentials.

Network dashboard: /network.html. Shared Memory encrypts bodies under the account key and searches metadata only. MCP Hub rejects credential-bearing URLs. Marketplace reputation accepts only independent, server-signed VERIFIED receipts.

모든 공개 화면은 한국어를 기본으로 제공하며 /dash.html(협업방), /board.html(검증 결과), /ops.html(작업·Git·비용), /network.html(기억·MCP·에이전트)을 상호 연결한다.

Design principles (from the security review)

  • Code-derived encryption. The server stores only ciphertext + code_hash. Without the code, even the operator can't read the plaintext — the proof of "we can't lock you in."
  • Signed receipts. Verdicts are HMAC-signed server-side (BATON_RECEIPT_SECRET); no client can forge verified.
  • Prompt-injection containment. Inbound capsules/messages are returned fenced as untrusted data; secrets are auto-masked before storage.
  • Codes are ≥128-bit secrets, one-time codes redeem atomically, alias-spoofing blocked.
  • A passing build ≠ working behavior. verified requires observed side effects, never static analysis alone.

Billing/gating is off by default (dogfooding phase). Set BATON_BILLING=on to re-enable quotas. See USAGE.md for the full guide.

Storage

MVP uses SQLite (better-sqlite3) — self-host single binary. The hosted service drops a Postgres adapter into the narrow interface in src/store.js.
